When assessing fire hazards, which items should be checked?

• A. Roof
• B. Combustibles around the welding area
• C. Workspace floors
• D. All of the above

Answer: (D)

When evaluating fire hazards in welding, you look for any potential ignition sources in the entire area, not just one spot. Sparks and molten metal can ignite materials overhead, on the floor, or in nearby surroundings, so a thorough check covers overhead surfaces like the roof, any combustibles around the welding area (solvents, oils, rags, paints, wood, etc.), and the workspace floors themselves (spills, oily residues, or flammable floor coverings). Because all of these areas can pose a fire risk, the safest and most complete approach is to inspect each one.
