A concept that can be used in job safety analysis is “line of fire” assessment. “Line of fire” is the path an object may travel. On a typical jobsite, there are hazards that may possibly expose workers to line of fire danger. To evaluate these hazards in a JSA or JHA, it’s essential to identify all tools, equipment and other items with the potential to become mobile, then understand their possible trajectories and safeguard against them.
While conducting your JSA or JHA, remember to consider:
Fall potential – Top-heavy equipment or loads that may be susceptible to toppling over, and items on a forklift, dolly, or flatbed truck.
Roll Potential – All wheeled equipment should have parking brakes and wheel chocks implemented, especially for vehicles parked on an incline. Check for cylinders, poles and other tools that might roll or spin, and secure these items.
Swing Potential – Identify and secure all suspended items, especially ones with hooks, pulls, straps and buckles.
Pressurized Potential – Check that caps on pressurized cylinders and lines are tightly fitted and tanks are secured.
Spring Potential – Objects that are spring-loaded or contain coils can exert tremendous energy if compression is released suddenly or unexpectedly.
