I.
Testing Methods For Positioning Device Systems.
This
appendix serves as a non-mandatory guideline to assist employers
comply with the requirements for positioning device systems
in 1926.502(e). Paragraphs (b), (c), (d) and (e) of Appendix
C of subpart M relating to 1926.502(d) - Personal Fall Arrest
Systems - set forth test procedures which may be used, along
with the procedures listed below, to determine compliance with
the requirements for positioning device systems in 1926.502(e)(3)
and (4) of Subpart M.
(a)
"General." (1) Single strap positioning devices shall
have one end attached to a fixed anchorage and the other end
connected to a body belt or harness in the same manner as they
would be used to protect employees. Double strap positioning
devices, similar to window cleaner's belts, shall have one end
of the strap attached to a fixed anchorage and the other end
shall hang free. The body belt or harness shall be attached
to the strap in the same manner as it would be used to protect
employees. The two strap ends shall be adjusted to their maximum
span.
(2)
The fixed anchorage shall be rigid, and shall not have a deflection
greater than .04 inches (1 mm) when a force of 2,250 pounds
(10 kN) is applied.
(3)
During the testing of all systems, a test weight of 250 pounds
plus or minus 3 pounds (113 kg plus or minus 1.6 kg) shall be
used. The weight shall be a rigid object with a girth of 38
inches plus or minus 4 inches (96 cm plus or minus 10 cm).
(4)
Each test shall consist of dropping the specified weight one
time without failure of the system being tested. A new system
shall be used for each test.
(5)
The test weight for each test shall be hoisted exactly 4 feet
(1.2 m above its "at rest" position), and shall be
dropped so as to permit a vertical free fall of 4 feet (1.2
m).
(6)
The test is failed whenever any breakage or slippage occurs
which permits the weight to fall free of the system.
(7)
Following the test, the system need not be capable of further
operation; however, all such incapacities shall be readily apparent.
II.
Inspection Considerations.
As
required in 1926.502 (e)(5), positioning device systems must
be regularly inspected. Any component with any significant defect,
such as cuts, tears, abrasions, mold, or undue stretching; alterations
or additions which might affect its efficiency; damage due to
deterioration; contact with fire, acids, or other corrosives;
distorted hooks or faulty hook springs; tongues unfitted to
the shoulder of buckles; loose or damaged mountings; non-functioning
parts; or wearing or internal deterioration in the ropes must
be withdrawn from service immediately, and should be tagged
or marked as unusable, or destroyed.
