The document outlines critical controls for line of fire safety including establishing and honoring barriers and buffer zones, properly positioning people to avoid hazards, and protecting against dropped objects. Specific considerations are given for barriers, the positioning of people during pressure releases, working with vehicles and heavy equipment, suspended loads, moving objects, equipment under stress, and pinch points. Preventing dropped objects by securing tools and establishing exclusion zones below overhead work is also emphasized.

Critical Controls
The Critical Controls for Line of Fire are:
• Establish, maintain, and honor barriers and buffer zones
• Position yourself and others to avoid line of fire hazards
• Protect against dropped objects.
Barriers and Exclusion Zones
When establishing barriers and buffer zones consider the following:
• Overhead lifts, pressure testing, moving equipment, overhead work, etc.
• Completeness, maintenance, and communication of barricades
• Adherence to barriers and buffer zones.
Positions of People
When determining proper position of people during work, consider:
• Pressure Releases
o breaking flanges and hose connections, removing plugs, blowing down equipment, pressure testing
• Vehicles and Heavy Equipment
o barricades, spotters, evaluation, and planning of traffic patterns.
• Suspended and Swinging Loads
o tethering of tools/equipment, management of loads with tag lines and guide poles, evaluation of
centers of gravity and environmental conditions.
• Moving Objects
o unexpected movement of tools or equipment, securing of materials such as piping.
• Equipment in Stress
o (compression, tension, or bent) – expected direction of energy release in a failure scenario.
• Pinch Points activities that subject people to crushing injuries
Prevent Dropped Objects
Protect against dropped objects:
• Secure tools and equipment from falling to a lower level
• Establish and maintain exclusion zones below overhead work
