(2) “For lanyard systems. ” (i) A test fat of 220 pounds plus or minus 3 pounds (100 kg plus or minus 1.6 kg) should always be utilized. (See paragraph (b)(4) for this appendix).
(ii) Lanyard length should always be 6 legs plus or minus two ins (1.83 m plus or minus 5 cm) as calculated through the fixed anchorage to your accessory from the human body gear or body harness.
(iii) The test fat should fall free of the anchorage degree to its hanging location (a complete of 6 legs (1.83 m) free autumn distance) without disturbance, obstruction, or striking a floor or ground through the test.
(3) “for several other systems. ” (i) A test fat of 220 pounds plus or minus 3 pounds (100 kg plus or minus 1.6 kg) must certanly be utilized. (See paragraph (b)(4) for this appendix)
(ii) The free autumn distance to be utilized within the test ought to be the maximum fall distance actually allowed because of the system during normal usage conditions, as much as a maximum free autumn distance for the test fat of 6 legs (1.83 m), except the following:
(A) For deceleration systems which may have a connection link or lanyard, the test fat should free fall a distance corresponding to the bond distance (calculated between your centerline associated with the lifeline and also the accessory point out your body gear or harness).
(B) For deceleration unit systems with key lifelines or lanyards which immediately restrict free fall distance to 2 foot (0.61 m) or less, the test fat should free fall a distance corresponding to that allowed by the machine in normal usage. (as an example, to try a system by having a lifeline that is self-retracting lanyard, the test fat must be supported plus the system permitted to retract the lifeline or lanyard since it would in normal usage. The test weight would be released and then the force and deceleration distance calculated).
(4) something fails the force test in the event that recorded maximum arresting force surpasses 1,260 pounds (5.6 kN) when utilizing a human body belt, and/or surpasses 2,520 pounds (11.2 kN) when utilizing a human body harness.
(5) the utmost elongation and deceleration distance ought to be recorded through the force test.
( ag ag e) “Deceleration device tests. ” (1) “General. ” These devices should really be examined or tested underneath the environmental conditions, (such as for instance rainfall, ice, oil, dust, types of lifeline, etc. ), which is why these devices is made .
(2) “Rope-grab-type deceleration devices. ” (i) Devices must be managed to move on a lifeline 1,000 times on the exact same amount of line a distance of no less than 1 base (30.5 cm), plus the system should secure each and every time.
(ii) Unless the product is completely marked to point the type(s) of lifeline which can be used, a few kinds (different diameters and various materials), of lifelines should really be utilized to try the product.
(3) ” Other deceleration that is self-activating-type. ” The securing mechanisms of other deceleration that is self-activating-type made for multiple arrest should secure all of 1,000 times because they would in normal solution.
II. Extra non-mandatory tips for individual autumn arrest systems. Listed here information comprises extra tips for use within complying with needs for a individual autumn arrest system.
(a) “Selection and make use of factors. ” (1) The type of individual autumn arrest system selected should match the work that is particular, and any feasible free autumn distance must certanly be held to the absolute minimum. Consideration must certanly be directed at the specific work place. As an example, the clear presence of acids, dust, dampness, oil, oil, etc., and their impact on the system, must certanly be examined. Hot or cool environments could also have a negative impact on the device. Wire rope shouldn’t be utilized where a hazard that is electrical expected. The employer must plan to have means available to promptly rescue an employee should a fall occur, since the suspended employee may not be able to reach a work level independently as required by the standard.
(2) Where lanyards, connectors, and lifelines are at the mercy of harm by work operations such as for example welding, chemical cleansing, and sandblasting, the component ought to be protected, or other securing systems should always be utilized. The boss should completely evaluate the work conditions and environment (including seasonal weather changes) before choosing the correct personal autumn security system. As soon as being used, the machine’s effectiveness should really be checked. In many cases, a program for cleaning and maintenance associated with system might be necessary.
