     You must:

     • Make sure ladder safety devices and related support systems meet all of the following:

     – Are capable of withstanding, without failure, the test drop of a five hundred pound weight for a free-fall distance of eighteen inches.

     – The device does not require a person to continually hold, push, or pull any part of the device and allows them to have both hands free to grip the ladder.

     – In the event of a fall, the device:

     ▪ Is activated within two feet

     and

     ▪ Limits the fall velocity to seven feet per second or less.

     – Uses a connection between the carrier or lifeline and the point of attachment on the full body harness that is not longer than nine inches.

     • Make sure ladder safety devices with rigid carriers have mountings that:

     – Are attached at each end of the carrier

     and

     – Have intermediate mountings that are all of the following:

     ▪ Spaced along the entire length of the carrier in accordance with the manufacturer's recommendations.

     ▪ Installed within one foot below each splice on the carrier.

     ▪ Have a maximum distance between mountings that is twenty-five feet or less.

     • Make sure ladder safety devices with flexible carriers have:

     – Mountings that are attached at each end of the carrier

     and

     – Cable guides that are spaced at least twenty-five feet, but no further than forty feet, apart along the entire length of the carrier.

     • Make sure the design and installation of mountings and cable guides does not reduce the design strength of the ladder.
