Falls: Problems and Solutions
Deck openings or penetrations create fall hazards if not properly guarded.
Horse staging is frequently used to access areas where work is to be done. While fall protection such as back rails is not required unless the staging is above five feet, working from a single plank is not a safe or acceptable practice. A fall of just a few feet can result in serious injury.
During ship construction or refitting, trip hazards may be unavoidable and may pose the potential for impalement.
Pipe guardrails can be quickly erected to provide adequate fall protection. Make sure that the materials to provide fall protection are readily available on hand prior to removing the cover or to making an access cut. This will eliminate the need for the shipfitter to leave the unguarded opening unattended while obtaining the necessary materials for fall protection.
Double planking with two10-inch planks provides the extra width needed to ensure that a step backward will not end in the emergency room. Planks must extend at least six inches beyond the supports, but not more than twelve inches. When horse staging reaches five feet in height, fall protection (such as guardrails) must also be used and toeboards may be needed as well.
Studs and pipe caps (as seen here) can prevent trip or fall hazards from resulting in impalement.
