Scissor lifts are one of the most popular ways for workers to reach projects at heights. But do the guard rails on these lifts provide all the fall protection necessary for the workers utilizing them?
The American National Safety Institute (ANSI) deems guard rails around the work platform to be a sufficient fall prevention measure. But in practice they may not be. Fall protection needs to be evaluated in relation to the work being performed. If you have a scissor lift in operation at your facility, it’s a good idea to have your OSHA-defined competent person evaluate the potential fall hazards posed by the work performed in your lift.
Are scissor lifts superior to ladders? Of course. They offer a compact, stable, and highly maneuverable platform from which to work. Once a worker is trained on the scissor lift, they can drive it directly to the project, raise the platform to the desired level, and get to work. But the possibility does exist that certain jobs may require body positioning which puts a worker in danger of falling either through the space below the rails or over the top of the guardrails.
Corrective measures for potential falls often include the use of a fall arrest system. Incorporating these new safety measures into your existing fall safety program will include not only the use of an anchor point, connection device, harness, and SRL or appropriate lanyard, but also a plan for prompt rescue in the event of a fall. Most lifts will include a clearly marked and rated anchor point. If yours does not, it’s important to contact the manufacturer before installing this anchor point to receive structural information and authorization.
Fall arrest in scissor lifts is most often accomplished with the use of self-retracting lifelines (SRLs) like the DBI-SALA Nano-Lok made specifically for a bucket truck or aerial lift. Because most work is done at an average of 14 ft. according to EHS Magazine (Vol. 6, No. 2), shock-absorbing lanyards often don’t serve because their average clearance can be over 16.5 feet. Workers need to be fully aware of the distance to the next lower level and understand the limitations of their fall protection when using lifts.
