13. © MSA Shock Absorbing Lanyards n Classification u Type A – separation of woven material u Type B – stretching of woven material n Sizes u Minimum lengths n Connectors u Locking snaphooks or carabiners u Sewn fiber loops

14. © MSA Product Testing: Harnesses and Shock Absorbing Lanyards n Electric Arc Exposure Testing u ASTM F1958/F 1958M n Post Arc-Exposure Testing u ANSI Z359.1 Fall Arrest Components u Dynamic Drop Test Testing confirms that the equipment will continue to function after exposure to an electric arc flash of very high intensity

15. © MSA Electric Arc Performance n Test Method ASTM F 1958/ F 1958M “Standard Test Method for Determining the Ignitability of Non-Flame-Resistant materials for Clothing by Electric Arc Exposure Method Using Mannequins” n Relevance to Fall Protection PPE u Worn over outerwear u Protection against flame and melting

16. © MSA Electric Arc Testing n Harnesses placed on mannequins as normally worn n Six test samples u 3 exposed on the front u 3 exposed on the back n Exposed to an intense electric arc flash with a thermal energy transfer of 40 cal/cm 2 (plus or minus 5 cal/cm 2)

17. © MSA Electric Arc Test - Example of Test Non-Compliance n Video of actual testing conducted at Kinetrics High Voltage Test Lab, QC, Canada n Observe explosive intensity of arc flash n Test Criteria: u No electric arc ignition u No melting or dripping u No greater than 5 s of afterflame (click to play video)

18. © MSA Electric Arc Test – Example of Successful Test n Test Criteria: u No electric arc ignition u No melting or dripping u No greater than 5 s of afterflame n Harness in this example does not support an afterflame and webbing does not melt (click to play video)

19. © MSA Drop Testing n Performed as soon as possible after electric arc test n For Harnesses: u 6 ft free-fall distance with 220 lb rigid test torso u Head-first and feet-first drops n For Lanyards: u 6 ft free-fall distance with 220 lb rigid test mass u 1800 lbf maximum arrest force u 42 in maximum elongation

20. © MSA Value Added by the New Standard n Improved methods for evaluating fall protection equipment used in an electrical hazards environment n Additional assurance that equipment will function to arrest a fall after thermal shock of a high-energy arc flash

21. © MSA Applications for Equipment Certified to ASTM F887-05 n Utility linesmen n Construction workers exposed to energized electrical sources n Maintenance and repair personnel working in electrical vaults n Tree trimmers working in proximity to high voltage power lines

22. © MSA Importance of Third Party Certification n Independent testing and certification of equipment to the standard n Validation of manufacturer’s quality management system n Regular verification testing to assure ongoing compliance n Provisions for recall in the event of non-compliance
