The employer must ensure that each positioning system meets the following requirements:
All positioning systems, except window cleaners' positioning systems, are capable of withstanding, without failure, a drop test consisting of a 4-foot (1.2-m) drop of a 250-pound (113-kg) weight;
Positioning systems, including window cleaners' positioning systems, that meet the test methods and procedures in appendix D of this subpart are considered to be in compliance with paragraphs (e)(1)(i) and (ii).
Lineman's body belt and pole strap systems must meet the following tests:
A dielectric test of 819.7 volts, AC, per centimeter (25,000 volts per foot) for 3 minutes without visible deterioration;
A leakage test of 98.4 volts, AC, per centimeter (3,000 volts per foot) with a leakage current of no more than 1 mA; and
A flammability test in accordance with Table I-7 of this section.
|Test Method||Criteria for Passing Test|
|1.Vertically suspend a 19.7-inch (500-mm) length of strapping supporting a 220.5-lb (100-kg) weight;||Any flames on the positioning strap must self-extinguish.|
|2. Use a butane or propane burner with a 3-inch (76-mm) flame;||The positioning strap must continue to support the 220.5-lb (100kg) mass.|
|3. Direct the flame to an edge of the strapping at a distance of 1 inch (25-mm);|
|4. Remove the flame after 5 seconds; and|
|5. Wait for any flames on the positioning strap to stop burning.|
All window cleaners' positioning systems must:
Be capable of withstanding without failure a drop test consisting of a 6-foot (1.8-m) drop of a 250-pound (113-kg) weight; and
Limit the initial arresting force on the falling employee to not more than 2,000 pounds (8.9 kN), with a duration not exceeding 2 milliseconds and any subsequent arresting forces to not more than 1,000 pounds (4.5 kN).
