pact. Following are some general considerations for each part of a personal fall protection system.
Anchorage connectors are a vital part of any fall protection system. They need to be tested to ensure they are strong enough to withstand the tremendous forces generated by a fall. The most critical consideration in selecting an appropriate anchorage is where the worker will tie-off. If you are able to connect directly to the scaffolding, a scaffold choker anchor is an appropriate solution. This type of anchor wraps around the scaffold support and features a compatible D-ring to connect the lanyard. As mentioned above, if you cannot connect directly to the scaffolding, a permanent or temporary anchor can be used on a permanent structure that allows the anchorage point to be above or adjacent to the worker.
On mobile platforms, employers need to decide whether the worker will connect to an anchor inside the bucket or basket, or on the boom arm. Based on this selection, it is quite simple to determine whether a permanent or temporary anchor is desired. Anchors that connect inside a bucket or basket are permanent options, while anchors that connect to the boom arm are usually temporary.
A full body harness is designed to distribute fall arrest forces to the upper thighs, pelvis, chest and shoulders. A harness should be selected based on the application and environment in which it will be used. Consider the worker's comfort and time spent working in the harness. A comfortable harness has adjustment points on the legs, waist, chest and shoulders, as well as padding and lining to help increase the comfort level. A harness featuring breathable lining that wicks moisture away from the body helps workers stay dry and comfortable in hot or cold weather.
When it comes to connecting the anchorage and harness, there are two main connector options: lanyards and self retracting lifelines (SRLs). SRLs should be used if a worker requires more mobility. When less mobility is needed, a lanyard can be used. Lanyards are a fixed length with a connector at each end to connect the anchorage to the
