BOA 2015 -009 Hold a public hearing, consider and act upon a request for a variance to UDC Article 9, Section 21.9.8.B.2.b. Prohibited Materials, in order to permit an electric fence to be installed at 18115 IH- 35N. Mr. Dziewit opened the Public Hearing at 6:04 P.M. Mr. Cox gave the presentation on BOA201.5 -009 by stating that the Applicant is requesting a variance to Article 9, Sec.21.9.8, Screening and Fencing to allow an electric fence around the Minutes Board of Adjustment October 26, 2015 Page 1 of 3 perimeter of the storage yard on the subject property. The public hearing notice was published in "The Daily Commercial Recorder" on October 8, 2015 and in the "Herald" on October 14, 2015. There were five (5) notices mailed to surrounding property owners on October 7, 2015. At the time of this meeting, two (2) responses have been received; one (1) in favor of the request from the subject property owner and one (1) neutral to the request. The subject property is an approximately 3 acre tract of land containing two buildings totaling approximately 32,000 square feet of floor space and is occupied by a heavy equipment sales, service or rental facility. The applicant is requesting a variance to allow an electric fence around the storage yard which is not permitted by the Unified Development Code (UDC). Pursuant to the UDC Article 9, Section 21.9.8.B.2.b, Fences Nonresidential and Multifamily Areas: Prohibited Materials, above - ground electrical fencing, wire mesh (such as hog wire or chicken wire), screening slats within chain link fences and barbed wire are prohibited except for parcels or lots one (1) acre or greater in size in conjunction with the containment of livestock or farm animals. The applicant installed a ten foot (10') electric fence without a permit around the storage yard at the subject property. The Building Inspections department discovered the fence while conducting scheduled inspections for permitted interior renovation work. Staff met with the owner and applicant to discuss the fence and code violation. The applicant and property owner expressed a desire to seek a variance for the electric fence. Based on discussion between the Building Office and the property owner the fence has been lowered to eight feet (8') in height, which is the maximum height permitted by the UDC, and de- energized for the duration of the variance process. The property is located at 18115 IH -35N, approximately 3,250 feet east of the intersection of FM 3009 and IH -35N. According to UDC, Article 3, Sections 21.3.4.C, in order to make a finding of hardship and grant a variance from the zoning regulations of the UDC, the Board must determine the following: 1. The requested variance does not violate the intent of this UDC or its amendments; UDC Article 9 is intended to enhance property values, maintain aesthetic attractiveness, and promote commercial opportunity in the City, and to support and further the objectives of the City's Comprehensive Land Plan. The variance does not meet the intent of the UDC because the requested electric fence is not being used for the containment of livestock and is expressly prohibited by the UDC. 2. Special conditions of restricted area, topography or physical features exits that are peculiar to the subject parcel of land and are not applicable to other parcels of land in the same zoning district; The purpose of this variance is to acknowledge the special circumstances particular to the subject property. The subject property is not influenced by conditions that are unique to the land or land use. 3. The hardship is in no way the result of the applicant's own actions; or 4. The interpretation of the provisions in this UDC or any amendments thereto would deprive the applicant of rights commonly enjoyed by other properties in the same zoning district that comply with the same provisions. The property has no special circumstances or unique conditions that would result in the need of the variance requested. The variance request conflicts with the provisions of the UDC. Currently properties within the City of Schertz requesting a permit for a new fence are subject to the same electric fence and barbwire regulations. Staff recommends denial of BOA 2015 -009. The request for a variance does not comply with all the criteria for granting a variance as presented above. The applicant desires to erect an electric fence that is not in compliance with what is allowed per Code and does not provide sufficient justification Minutes Board of Adjustment October 26, 2015 Page 2 of 3 for granting a variance. Mr. Pate, the Applicant, that they are a licensed alarm contractor in the state of Texas and stated that they did the research and didn't find the section mentioned, and this system is hooked up to a battery powered by solar. He also stated that the UDC mentioned that this type of fence can be in the zone if there is livestock, and they could put up a chicken coop if they wanted. He also stated that the power lines are next to the access easement and this gives easy access to the property, and in addition that the back of the property is a wooded area and those are reasons why they applied for the variance. Mr. Dziewit closed the Public Hearing at 6:13 P.M. Mr. Hartzog asked about the voltage that is going similar to cattle fence and operates on 115th of the c were pictures to explain this interior fence. Mr. already permitted the 8' chain link fence, and the similar to other fences in Texas and the San Anton the UDC of those locations. Mr. Pate answered no rough the fence.

GENERAL INFORMATION: Owner/ Applicant: Bella Vista C.M.I., Ltd., Steve Louis and Tim Pruski Surveyor: Sinclair Land Surveying, Inc., Neil Linnen REQUEST: The applicant is requesting a variance to UDC Article 5, Section 21.5.7 Dimensional and Development Standards, in order to permit an encroachment of two and one half feet (25) into the front building setback at 5504 Devonwood Street (Lot 15, Block 5 or Cypress Point Subdivision Unit 2). PUBLIC NOTICE: The public hearing notice was published in "The Daily Commercial Recorder" on January 8, 2016 and in the "Herald" on January 13, 2016. There were twenty three (23) notices mailed to surrounding property owners on January 14, 2016. At the time of this staff report only one (1) response has been received, which is in favor of the request. ITEM SUMMARY: The subject property is zoned Single- Family Residential District - 7 (R -7) with an approximately 2,500 square foot single family home. The eight foot (8) wide front porch encroaches two and one half feet (25) into the front building setback. It was discovered by the applicant after having a final survey of the lot performed as a prerequisite for receiving a certificate of occupancy, that the front porch of the home was located twenty two and one half feet (225) from the property line. The minimum front building setback for the R -7 zoning district is twenty five feet (25) meaning the porch encroaches into the setback by two and one half feet (25). After investigating how this encroachment occurred it was determined that there was an error made by the surveyor on the original site survey. The original site survey shows the home being constructed behind the twenty five foot (25) front building setback line, however the survey calls out a specific dimension to the front porch of twenty two feet (22) and a distance to the front wall of the house of twenty four and nine tenths feet (24.9'). The labeled front building setback line and specific called measurements are in conflict. When measured, the building setback line is not scaled correctly. The Plan Reviewer for the City missed this discrepancy and the original site survey was approved as part of the building permit. SUBJECT PROPERTY GENERAL LOCATION ZONING AND LAND USE: The property is located at 5504 Devonwood Street. Existing Zoning I Existing Use Single- Family Residential District - 7 (R -7) I Single Family Residential Existing Zoning Existing Use North Single- Family Residential District - 7 (R -7) Single Family Residential South Single- Family Residential District- 7 (R -7) Single Family Residential East Single- Family Residential District- 7 (R -7) Single Family Residential West Right -of -way and Single - Family Residential Devonwood Street and Single Family Residential District - 7 (R -7) CRITERIA FOR REVIEW: According to UDC, Article 3, Sections 21.3.4.C, In order to make a finding of hardship and grant a variance from the zoning regulations of the UDC, the Board must determine the following: The requested variance does not violate the intent of this UDC or its amendments; Residential front building setbacks serve a variety of purposes including, ensuring that the use of property does not infringe on the rights of neighboring property owners and also allows room for lawns, trees, recreation space and maintains visually pleasing green space. The encroachment does violate UDC Article 5, Section 21.5.7 Dimensional and Development Standards, however the encroachment is minimal in nature being only a two and one half foot (2.5) into the setback for only the width of the front porch and does not violate the intent of the UDC. 2. Special conditions of restricted area, topography or physical features exits that are peculiar to the subject parcel of land and are not applicable to other parcels of land in the same zoning district; The subject property is not influenced by conditions that are unique to the land or that prevents the property owners from utilizing their property. 3. The hardship is in no way the result of the applicant's own actions; or The hardship is not the result of the applicant's own actions. The hardship was created by an error made by the surveying company on the site survey which caused the foundation to be placed two and one half feet (2.5) into the front building setback. The error was not intentional and the foundation was poured in compliance with the approved building permit. 4. The interpretation of the provisions in this UDC or any amendments thereto would deprive the applicant of rights commonly enjoyed by other properties in the same zoning district that comply with the same provisions.

No. The variance request does not violate the intent of the UDC Section 21.5.7.A. Only a portion of the covered front porch and columns encroach 2.5' x 8' into the front setback and the remaining structure of the home is setback at 25' as attached in survey provided with request. The driveway for the residence is setback 25' as typical of other properties in the subdivision. 2. No. There are no special conditions to the property. The encroachment was not detected until the final survey was performed by Sinclair Land Surveying for the property. The encroachment was caused by a survey form verification approval to proceed to pour foundation provided by Sinclair Land Surveying due to an administrative error of mislabeling of setback lines on the site plan used for the building permit application and applicant was allowed to pour the foundation. 3. No. The hardship was not a result of the applicant's own actions or intended for financial interest. The applicant proceeded with pouring the foundation after all inspections were passed and form verification was provided by Sinclair Land Surveying to proceed. An administrative error by the surveyor caused the encroachment and was not detected until a final survey was performed. 4. No. By granting this variance, it will not be detrimental to the public welfare or injurious to the value of the property. The property functions the same as all other properties in the subdivision. Except for the 2.5' x 8' of front covered porch encroachment, all other aspects of the property are in compliance with the City of Schertz Ordinances and Codes as this residence has received a Certificate of Occupancy and a letter from the Cypress Point Homeowner's Association allowing the covered front porch to encroach.

Prohibited Materials, in order to permit an electric fence to be installed at 18115 IH -35N. GENERAL INFORMATION: Owner: MAS Development CO LP, Trevor Williams Applicant: Electric Guard Dog LLC, Michael Pate Engineer: Alliance Engineering of Oregon, Jenn Artigo REQUEST: The applicant is requesting a variance to Article 9, Sec.21.9.8, Screening and Fencing to allow an electric fence around the perimeter of the storage yard on the subject property. PUBLIC NOTICE: The public hearing notice was published in "The Daily Commercial Recorder" on January 8, 2016 and in the "Herald" on January 13, 2016. There were five (5) notices mailed to surrounding property owners on January 14, 2016. At the time of this staff report no responses have been received. ITEM SUMMARY: The subject property is an approximately 3 acre tract of land containing two buildings totaling approximately 32,000 square feet of floor space and is occupied by a heavy equipment sales, service or rental facility. The applicant is requesting a variance to allow an electric fence around the storage yard which is not permitted by the Unified Development Code (UDC). Pursuant to the UDC Article 9, Section 21.9.8.B.2.b, Fences Nonresidential and Multifamily Areas: Prohibited Materials, above - ground electrical fencing, wire mesh (such as hog wire or chicken wire), screening slats within chain link fences and barbed wire are prohibited except for parcels or lots one (1) acre or greater in size in conjunction with the containment of livestock or farm animals. The applicant installed a ten foot (10') electric fence without a permit around the storage yard at the subject property. The Building Inspections department discovered the fence while conducting scheduled inspections for permitted interior renovation work. Staff meet with the owner and applicant to discuss the fence and code violation. The applicant and property owner expressed a desire to seek a variance for the electric fence. Based on discussion between the Building Office and the property owner the fence has been lowered to eight feet (8') in height, which is the maximum height permitted by the UDC, and de- energized for the duration of the variance process. The property is located at 18115 IH -35N, approximately 3,250 feet east of the intersection of FM 3009 and 11-1- 35K Existing Zoning I Existing Use General Business (GB) I Heavv Eauioment Sales.

The requested variance does not violate the intent of this UDC or its amendments; UDC Article 9 is intended to enhance property values, maintain aesthetic attractiveness, and promote commercial opportunity in the City, and to support and further the objectives of the City's Comprehensive Land Plan. The variance does not meet the intent of the UDC because the requested electric fence is not being used for the containment of livestock and is expressly prohibited by the UDC. 2. Special conditions of restricted area, topography or physical features exits that are peculiar to the subject parcel of land and are not applicable to other parcels of land in the same zoning district; The purpose of this variance is to acknowledge the special circumstances particular to the subject property. The subject property is not influenced by conditions that are unique to the land or land use. 3. The hardship is in no way the result of the applicant's own actions; or 4. The interpretation of the provisions in this UDC or any amendments thereto would deprive the applicant of rights commonly enjoyed by other properties in the same zoning district that comply with the same provisions. The property has no special circumstances or unique conditions that would result in the need of the variance requested. The variance request conflicts with the provisions of the UDC. Currently properties within the City of Schertz requesting a permit for a new fence are subject to the same electric fence and barbwire regulations. STAFF ARAILTSIS STAFF RECO The Chief Building Official's determination based on the documentation provided by the applicant is that this fence will carry an electrical charge which may be transferred through the human body when the fence is touched, therefore this fence is considered an electric fence. The request for a variance does not comply with all the criteria for granting a variance as presented above. The applicant desires to erect an electric fence that is not in compliance with what is allowed per Code and does not provide sufficient justification for granting a variance. Staff recommends denial of BOA 2015 -009. iN Planning Department Recommendation Approve as submitted Approve with conditions* X I Denial * While the Board can impose conditions; conditions should only be imposed to meet requirements of the UDC.

' `l' 16Nanance Checklist VpW1alY0.�d Pa-e 2 ur2 Variance Request — We Rent it, Schertz TX We are requesting variance to install a security fence system (Electric Guard Dog aka EGD) approximately 3 -12 inches inside /behind the existing perimeter chain link fence at We Rent It located at 18115 IH -35 N, Schertz TX. The EGD Security system is a powered by 12V marine battery which is charged by solar panel. The fence is an audible alarm and the sirens will sound if the fence is compromised. Security signage is posted a minimum of every 60 feet. With this, the EGD proactively' deters crime unlike cameras, beams and alarms that react to a crime in commission. This genre of business is a high target for crime due to the fact that their yard contains highly desirable, easily `fenceable' inventory of commercial and residential materials and equipment. Currently, We Rent It has a chain link fence around the perimeter of the property for security and to prevent intruders. This security system has proven ineffective. Many businesses in this industry use EGD security systems to effectively protect their property where other systems have failed. Essential safety facts regarding Electric Guard Doe fence a Powered by 12V marine: battery and solar panel a Totally enclosed inside perimeter fence of 6' minimum height. a Adheres to International Standard lEC: 60336.2.76. of which the United States is a supporting member a Response: The N1 Theft Deterrent Service in the U.S. 121 Executive Center Drive a Suite 230 =n` Columbia, SC 29210 Phone: (803) 404 -61891 Fax: (803) 404 -5378 The requested variance does not violate the current or any future intent of the Unified Development Code. Electric fences are allowed on parcels of greater than one acre; the property requesting the variance is three acres. The interpretation allows for electric fences in conjunction with the containment of livestock or farm animals. The requested variance is for a security fence powered by a 12 -volt DC battery and should not have to be used in conjunction with livestock or animals to keep the criminal class from burglarizing or vandalizing We Rent It —a tax paying business and employer in the City of Schanz. The implied use of animals toward off the criminal class in conjunction with an electric fence is not an effective form of security. The Electric Guard Dog security fence is proven to be safe and effective as a security deterrent. The remote location of the property and the high value targets secured therein are an open invitation to the criminal class. The only system that actually PREVENTS crime and break -ins is the Electric Guard Dog security system. We Rent It believes the variance is of the utmost importance to the protection of their business and inventory. Response: 2. Do special conditions or restricted area shape topography, or physical features exist that are irregular to the subject parcel of land and not applicable to other parcels of land in the same zoning districts? The subject property in question is unique in the following ways: a. High value of inventory— both the equipment and inventory; We Rent It is a supplier of all sizes of construction and residential type machinery and equipment. b. Due to size and nature of items, most must be stored outside and cannot be protected inside a building. These items consist of construction equipment, vehicles, and over - sized construction supplies. c The subject area is 1,120 linear feet in perimeter; it is not possible for security guards to effectively and constantly monitor the entire lot. d. Two sides of the property are screened by large trees and the eastern side is not able to be seen from the road due to the depth of the lot. Without the security system being sought; it is very easy to obtain access without being seen by patrolling Policemen or a neighborhood watch. e. The business is a reputable business, located in the appropriate zoning and complies with all other ordinances. If approved, the variance authorized will be consistent with the general purpose and intent of the provision from which the variance is sought as the general safety and welfare of the public is maintained, crime is prevented, and the city can police crime other than property break -ins and vandalism. 3. Is the hardship the result of the applicant's own actions or intended for financial 'interest? Response: This variance is not being sought to relieve illegal acts or self- imposed hardships. The business is a reputable business, located in the appropriate zoning and complies with all other ordinances. If approved, the variance authorized will be consistent with the general purpose and intent of the provision from which the variance is sought as the general safety and welfare of the public is maintained, crime is prevented, and the city can police crime other than property break -ins and vandalism. 4. Would granting this variance be detrimental to the public welfare or injurious to the value of property m the vicinity? Response: The granting of the variance will not be detrimental to the public welfare or injurious to the value of the property in the vicinity of We Rent It. In actuality the installation of the Electric Guard Dog will secure the variance property and increase the security of the surrounding properties and the immediate area by deterring the criminal element. It will be in be in harmony with the general purpose and intent of the approved standards and regulations for the installation of the Electric Guard Dog system. Electric Guard Dog has made a name for ourselves by protecting companies tike this one from criminals, we have a certain way of setting up our system fences that is safe to the public and allows for maximum protection of our clients. This is why the client has elected to use our service to protect the business; we have the expertise and experience in creating defense systems that are both safe and effective. Our Electric Guard Dog security system is a primary low voltage (12V), battery powered (DC), independent of the electrical grid, self - contained system that has a variety of functions to it which make for a 100% medically safe and extremely effective crime deterrent. This system is 10' high and is placed approximately 4" -12" inside of the existing perimeter fence. It is comprised of 20, 12.5 gauge, galvanized steel wires which are run horizontally to the height of 10'. In our system the first layer of protection (visual deterrent) is our.signage (located every 50'). This deters most would -be criminals. The second layer of protection (audible deterrent) of our system is sirens. These sirens sound when an illegal criminal trespasser cuts the wires or places objects on them to insulate them so as to bypass the system. The sirens will automatically shut off after a set amount of time. This audible deterrent usually drives away most of the would -be criminals that are bold enough to proceed in spite of the aforementioned visual deterrent (signage). Included in this second layer of protection is that we monitor our systems. In the event of an alarm, a signal will be sent to our monitoring station, who in turn, contacts our clients to let them know they had an alarm event. Our system does not directly connect to emergency services.

Hoeg can that happen and when? Walking across a carpet during (try weather, then touching it doorknob and feeling a spark- that jumps to the doorknob is a very common way. Placing a finger inside of a Tamp socket that inadvertently was turned on is yet tlnother. Touching the spank plug in a car or lawn mower has happened to many people as well. But why are we all still alive after receiving these electric shocks durinG a regular day? 6t /e are still alive because even thoigh the voltage is high, not enough electric c urrent flowed through our heart. Even when the voltage is high, when the current flows for only a very short duration we can not be electrocuted, Furthermore, it is even bard to get electrocuted in the home because the power line voltage of 120 volts can't drive enough continuous current through the High resistance of out- dry skin. Kitchens and bathrooms fall in a different category; they are dangerous places because our skin may be wet. When our skin is wet, our skin resistance is low and permits a large electric current to flow through the body as shown in Figure 1. A large enough current can cause ventricular fibrillation. During ventricular fibrillation the pumping action of the heart ceases and death occurs within - minutes - unless treated. In the United States, approximately 1000 deaths per year occur in accidents that involve cord - connected appliances in kitchens, bathrooms, and other wet locations. i -1 , sv,,1„l,�ni Siu ao d Myocardial } cauhaciiun 11�r tty4ti;l�`v lenticixan�jlf rllilllit Jill rrtl!Itll it Rcaphatwn'jur.lyss, fatigue, pain :6 icbao c."m 2tuealrald of pereept n i' J umd 1 1 1�1w! 1mA 10 mA 100 m SA to 100.A 604tr, ntrrcni, mis CIi C ii ; 1ll15 Figure 1 Physiological effects of electricity.

Note that as the shock duration is shortened to 0.2 seconds, it requires much more electric current to cause ventricular fibrillation. Electric security fences have taken advantage of this fact by shortening their shock duration to an even shorter duration of about 0.0003 seconds. Therefore, electric security fences are safe and do not lead to ventricular fibrillation due to the short 0.0003 second shock duration. .

It increases to about 800 milliamperes for 0.3 second shock duration. From L. A. Geddes, IEEE Trans. Biomed. Eng., 1973, 20,465-468. Electricity near the heart is most dangerous There are four situations where electricity may be applied close to the heart. (1) Figure 3(b) shows when a catheter tube is threaded through a vein into the heart, any accidental current is focused within the heart and a small current can cause ventricular fibrillation. (2) Cardiac pacemakers also pass electric current inside the heart, but the current is kept so small that ventricular fibrillation does not occur. (3) A Taser weapon may rarely shoot a dart between the ribs very close to the heart and apply a 0.0001 second pulse, but this has not been shown to cause ventricular fibrillation. Typically when a person takes an overdose of drugs, he creates a disturbance, police are called, the person refuses to obey, the police Taser him, afterwards he dies of a drug overdose, and the newspapers report, "Man dies after Taser shot." (4) A defibrillator applies a 0.005 second, 40 ampere electric current. This causes massive heart contraction that can change ventricular fibrillation to normal rhythm and save a life.

When comparing an electric security fence to the above examples, we know that an electric security fence is similar to Figure 3(a). Why do we know that? If a person contacts an electric fence, electric current is concentrated in the limbs and causes a deterrent shock; when it continues to pass through the torso, it spreads out and becomes more diffuse. Therefore as shown in Figure 3(a) and in Figure 2 electric security fences are safe because the deterrent shock spreads out and becomes more diffuse and is of a very short duration. Only power lines cause ventricular fibrillation Table 1 shows that short duration electric pulses, even though applied near the heart do not cause ventricular fibrillation. In contrast, the continuous current from power lines kills 1000 persons per year.

LC position on the relationship of security fences to codes and standards Electric fencing is used safely throughout the world, with applications for both animal control and contmercial security. In a commercial security setting, security fences dater crime and help apprehend criminals. The mere presence of a security fence discourages unlawful entry, theft and the destruction of property. hdditionally, it is easier to apprehend the detenuined criminal because the ow -ter and police are notified instantaneously when the criminal distorts or breaks the fence. Security fences also protect the people who work at a site, providing business owners and employees significant peace of mind. The security fence sold by Scntry Security Systems is powered by a 12 volt DC marine (or similar) battery. 'rho .National Electric Code does not cover battery powered products such as smoke alarms. Therefore, the security fence sold by Sentry Security Systems is not covered by the N.C. There is in fact no US standard that addresses security fences whother main or battery powered. CIE. 69 addresses animal control Fences but not security fences. There is, however, a good international standard - IEc 60:335 -2 -76 that addresses security fences. This standard is attached for your information. We respectfully request that you determine that; as a battery powered device, security fences do not fitll under the National Electric. Code.

Webster) Tel 608- 263 -1574, Fax 608- 265 -9239 Abstract The strength - duration curve for tissue excitation can be modeled by a parallel resistor - capacitor circuit that has a time constant. We tested five electric fence energizers to determine their current - versus- tirrre waveforms. We estimated their safety characteristics using the existing IEC standard and propose a new standard. The investigator would discharge the device into a passive resistor- capacitor circuit and measure the resulting maximum voltage. If the maximum voltage does not exceed a limit, the device passes the test. Key words: strength- duration curve, cardiac stimulation, vcntricular fibrillation, electric safety, electric fence energizers; standards. 1. Introduction The vast majority of work on electric safety has been done using power line frequencies such as 60 Hz. Thus most standards for electric safety apply to continuous 60 Hz current applied hand to hand. A separate class of electric devices applies electric current as single or a train of short pulses, such as are found in electric fence energizers (EFEs). A standard that specifically applies to EFEs is IEC (2006). To estimate the ventricular fibrillation (VF) risk of EFEs, we use the excitation behavior of excitable cells. Geddes and Baker (1989) presented the cell membrane excitation model (Analytical Strength- Duration Curve model) by a lumped parallel resistance - capacitance (RC) circuit. This model determines the cell excitation thresholds for varying rectangular pulse durations by assigning the strength - duration rheobase currents, chronaxie, and time constants (Geddes and Baker, 1989). Though this model was originally developed based on the experimental results of rectangular pulses, the effectiveness of applying this model for other waveforms has been discussed (IEC 1987, Jones and Geddes 1977). The charge- duration curve, derived from the strength - duration curve, has been shown in sound agreement with various experimental results for irregular waveforms. This permits calculating the VF excitation threshold of EFEs with various nonrectangular waveforms. We present measurements on electric fence energizers and discuss their possibility of inducing VF 2. Mathematical background and calculation procedures Based on the cell membrane excitation model(Weiss- Lapique model), Geddes and Baker (1989) developed a lumped RC model (analytical strength- duration curve) to describe the membrane excitation behavior. This model has been widely used in various fields in clectrophysiology to calculate the excitation threshold. Figure 1 shows the normalized strength - duration curve for current (1), charge (Q) and energy (0. The expression of charge is also known as the charge - duration curve which is important for short duration stimulations. 111-" C 0 3 x'.111! d 2 Duration d/r 0 v A w Figure 1. Normalized analytical strength- duration curve for current I, charge Q, and energy U. The x axis shows the normalized duration of dlr. Note that for d << z, Q is constant and the most appropriate variable for estimating cell excitation. (from Geddes and Baker, 1989). The equation for the strength - duration curve is (Geddes and Baker, 1989), t 4v= IR(1 -e r), (1) where I is a step current intensity, R is the shunt resistance, Av is the depolarization potential threshold which is about 20 mV for myocardial cells, r is the RC time constant, and t is the time I is applied. If we let the stimulation duration go to infinity, the threshold current is defined as the rheobase current (I = b). If we substitute I in equation (1) by b and define the threshold current Id = dvIR for the stimulation with duration d. Equation (1) becomes, Id = b d (2) 1 -e r We can calculate the threshold charge (Qd) by integrating equation (2) and it becomes, Qd =1dd= bd d, 1 -e ? (3) For short duration stimulation (d << r) with duration shorter than 0.1 times the RC time constant, equation (3) can be approximated by equation (4) and it yields equation (5), d 1 -e T (4) Qs = br (5) Equation (5) suggests that the charge excitation threshold for short duration stimulation is constant and equals the product of the RC time constants and the rheobase b. Geddes and Bourland (1985) showed that the charge— duration curve for single rectangular, trapezoidal, half sinusoid and critically damped waveforms had a good agreement for short duration stimulations. Therefore we used the same model to estimate thresholds for stimulation sources where l was not constant, under the same stimulation setting. Cardiaacell excitation has been intensively studied at the 60 Hz power line frequency because most accidental electrocutions occur with 60 Hz current, which has a longer duration relative to the cardiac cell time constant of about 2 ms. However, EFEs operate with pulse durations much shorter than the time constant. 3. Methods Figure 2 shows our experimental test set -up. The EFEs under test consist of Gallagher Group Ltd PowerPlus B600 (EFEI), Gallagher Group Ltd PowerPlus B280 (EFE2), Speedrite HPB (EFE3), Intellishock 20B (EF'E4) and Blitzer 8902 (EFE5) EFEs. The short duration electrical pulses from these EFEs are passed though a series of eleven 47 92 (ARCOL D4.29, HS50 47 R F) resistors which measure 518 0, which represents approximately the internal resistance of the human body. It is further connected to two 18 S2 (RE 10 207 DALE 10 W 3 %) resistors connected in parallel which measure 9.08 Si. This is used as the sensing resistor across which the oscilloscope measures the output voltage. For these very short pulses it is important to use noninductive resistors because the same current flowing through a resistor that has substantial inductance will measure a larger current than a resistor that is noninductive. To reduce electromagnetic interference, a faraday cage; covered with aluminum foil, was connected to ground. This diverted the electromagnetic interference to ground. The data were collected in EXCEL format from a disk in the Agilent 54621 oscilloscope. The calculations for different parameters presented in Table l and the Figures 3 -5 were plotted using MATLAB. 4 S3 `� 2 p'F r-- - -- - -- o R1 R2 R3 R11 S4 Oscilloscc S1 9.08 n2 � Agilent 200 pFi 54621 Faraday cage ' S2 ' ----------------------- ------- -- - - - --' Aluminum foil Aluminum Figure 2.

In 3.117 it defines "output current: r.m s. value of the output current per impulse calculated over the impulse duration." In 3.118 it defines "standard load` load consisting of a non - inductive resistor of 500 Q f 2.5 fl and a variable resistor that is adjusted so as to maximize the energy per impulse or output current in the 500 0 resistor, as applicable." In 22.108, "Energizer output characteristics shall be such that the impulse repetition rate shall not exceed 1 Hz; - the impulse duration of the impulse in the 500 n component of the standard load shall not exceed 10 ms; - for energy limited energizers the energy /impulse in the 500 Q component of the standard load shall not exceed 5 J The energy /impulses the energy measured in the impulse over the impulse duration. -for current limited energizers the output current in the 500 0 component of the standard load shall not exceed for an impulse duration of greater than 0.1 ms, the value specified by the characteristic limit line detailed in Figure 102; an impulse tchiration of not greater than 0.1 ms, 15 700 mA. The equation of the line relating impulse duration (ms) to output current (mA) for 1 000 mA < output current <;15 700 nnA, is given by impulse duration = 41.885 x 103 x (output current)- 1'34." We used these definitions and calculated the total energy, the shortest duration where 95% of the total energy occurs, the rms current for that duration from Figure 3 for the EFEs (EFEI- EFE5). Similarly we calculated the output current using the relationship impulse duration = 41.885 x 103 x (output current)" 1.3a provided by the IEC for all the EFEs (EFEI- EFE5). Table 1 lists these under the heading "A. (IEC) ". Table 1 shows that all the EFEs pass the IEC standard. 2015 5. Proposed new standard IEC (2006) uses the rms current for the shortest duration where 95% of the total energy occurs as the standard to determine if the EFE is safe for use. Geddes and Baker (1989) have shown that for pulses shorter than the cardiac cell time constant of 2 ms, the electric charge is the quantity that excites the cells. We propose a simple experimental set -up shown in Figure 2 to determine the maximum amount of charge that would flow from the EFEs and cause cardiac col l excitation. The cardiac cell is modeled as an RC circuit in Fig. 2 with R = 9.08 n and C = 200 µF (GECONOL 9757511FC 200 µF f10% 250 VPK) with the RC time constant of 1.82 ms. For the EFEs (EFEI and EFE2) the switches S1 and S4 are closed. This allows the 200 µF capacitor to charge rapidly (about 100 µs) and discharge fairly slowly (r= RC = 1.82 ms).

Discussion Geddes and Baker (1989) have shown that for pulses shorterthan the cardiac cell time constant of 2 ms, the electric charge is the quantity that excites cardiac cells. Because the first half wave is the largest, the charge integrated in the first half wave determines cardiac cell excitation. The next half wave discharges the cardiac cell capacitance and does not contribute to cardiac cell excitation. Thus we list integral I(t) = charge Q in Table 1. IEC (2006) integrates P(t), which is roughly equal to I(t). Their Figure 102 roughly follows charge. We propose revising EFE standards for measuring current to determine a safety standard to prevent VF. The new standard would measure cardiac cell excitation. It would not require the complex calculations required to determine "The current which flows during the time period in which 95 percent of the output energy (is delivered)." It would use a simple circuit similar to that in Figure 2 composed of resistors and a capacitor. The investigator would discharge the device into the circuit and measure the maximum voltage. If the maximum voltage does not exceed 5 V (as a conservative estimate), the EFE passes the test. The 500 n resistor closely approximates the resistance of the body and determines the current that flows through the body.

NOTE 1 This requirement is primarily intended to establish that a desirable level of safety is present or is being maintained in the physical barrier. NOTE 2 When selecting the type of physical barrier, the likely presence of young children should be a factor in considering the size of openings. CC.2 Location of electric security fence The electric fence should be separated from the public access area by means of a physical barrier. Where an electric fence is installed in an elevated position, such as on the inner side of a window or skylight, the physical barrier may be less than 1,5 in high where it covers the whole of the electric fence. If the bottom of the window or skylight is within a distance of 1,5 in from the floor or access level then the physical barrier need only extend up to a height of 1,5 m above the floor or access level. CC.3 Prohibited zone for pulsed conductors Pulsed conductors shall not be installed within the shaded zone shown in Figure CC1 NOTE i Where an electric security fence is planned to run close to a site boundary, the relevant government authority should be consulted before Installation begins. NOTE 2 Typical electric security fence installations are shown in Figure CC2 and Figure CC3. CCA Separation between electric fence and physical barrier Where a physical barrier is installed in compliance with CC.3 at least one dimension in any opening should be not greater than 130 mm and the separation between the electric fence and the physical barrier should be — within the range of 100 mm to 200 mm or greater than 1 000 mm where at least one dimension in each opening in the physical barrier is not greater than 130 mm; — greater than 1000 mm where any opening in the physical barrier has all dimensions greater than 50 mm; — less than 200 mm or greater than 1 000 mm where the physical barrier does not have any openings. NOTE i These restrictions are intended to reduce the possibility of persons making inadvertent contact with the pulsed conductors and to prevent them from becoming wedged between the electric Fence and the physical barrier, thereby being exposed to multiple shocks from the energizer. NOTE 2 The separation is the perpendicular distance between the electric fence and the physical barrier.

There should be no more than 6 inches from the insulators on a steel pole beside the gate, and the fiberglass pole that is mounted on the gate. if the steel pole cannot be set close enough to the gate pole or against a building, due to concrete footers, etc., causing a potential breach of security, attach a fiberglass pole to the building or gate post to close any gaps. 1.2C Steel poles Steel posts should be installed with a slight back lean, depending on the soil condition, so that after the fence settles and the con- crete dries, the poles will not lean into the yard. Poles should be set 5 ft deep with a 15" hole minimum. Unstable soil conditions will require a better foundation. 1:21) Double Poles Every site regardless of size must have break down points for troubleshooting. No section can be longer that 1,000 feet without double bracket pole for a break down spot. 1.2E Double Poles Cut off switches- are installed on the double bracketed pole and to bypass or isolate a section of fence. 1.21 Short. Sections A section of fence line that start and stops with Iootage of less than 251'. This section will have jumpers on each side, such as a section between two gates or a gate and a building or a roof sec- tion under 250ft. Short sections require springs on one end unless there is a 90 degree turn, in that case add a set of gate springs to the tg'n r end. e'} 3 h.d }5 l l r 7�a Ili.
