Many connecting devices can be properly used in more than one OPE system application. Some connecting devices, however, can be used for only one application. The intended use of each Klein OPE connecting device can be identified by one or more Klein use/function symbols printed on each product warning tag or warning packet. By careful selection, a connecting device can be chosen that offers the necessary features for the work to be done.

Choose a connecting device that is compatible with the OPE system you wish to use. Remember, OSHA prohibits the use of connecting devices with non locking snap hooks in Fall Arrest applications. Make sure your connecting devices are equipped with locking snap-hooks. The decision to use a particular connecting device or a combination of connecting devices (such as one for suspension, another for fall-arrest) in your fall-protection system is based not only on the specific job, but also on your job-site environment. Sharp-edged fall-arrest anchorages, such as I-beams, may require a nylon rope lanyard with wire pigtail; on the other hand, exposure to welding splatter requires a steel-cable lanyard.

Required length of all connecting devices should be determined before reaching the elevated position. Be sure the connecting device you choose for a job is designed and marked for that particular use. Misuse of a connecting device or any other piece of OPE equipment can result in serious injury or death. Know the job before selecting the connecting device.

Fall-arrest connecting devices must be short enough and attached to a fall-arrest anchorage in a manner that will limit a worker's free-fall to 6 ft. per OSHA regulations. OSHA also requires that the maximum impact force for a harness system be under 1,800 Ibs.

1. Use as short a length Fall Arrest connecting device as possible.
2. Minimize the amount of slack.
3. Always keep the fall-arrest anchorage above shoulder height.

Positioning Systems

Positioning connecting devices are intended to hold the worker close enough to the work position so that he will be able to get the job done with his hands free. The required length for the positioning connecting device depends upon the size of the structure to be used as the positioning anchorage.

Suspension connecting devices are often attached to winches, pulleys, and other mechanical devices. The length of a suspension connecting device depends on the job-site and equipment used to vertically hold the worker at the correct height to do the job.

Choose the shortest lanyard with a minimum amount of slack in order to allow fast removal of a worker in a potentially dangerous situation. The lanyard, however, should be long enough to allow the worker to move around and get the job done.
