How should flammable solvents and solvents be stored near a welding area?

• A. In approved flammable liquid cabinets, away from heat sources and ignition sources.
• B. In open containers on the bench.
• C. In the same cabinet as metal parts.
• D. Near the welding arc.

Answer: (A)

Flammable solvents must be stored away from heat and ignition sources in approved flammable-liquid storage cabinets. In a welding area, sparks and high heat can ignite vapors quickly, so using a dedicated cabinet helps contain vapors, restrict access, and provide fire resistance. Keeping containers closed and inside a proper cabinet minimizes the chance of spills and vapor buildup near the arc.

Storing solvents in open containers on a bench invites spills and allows vapors to spread, creating an immediate fire risk. Putting solvents with metal parts or near the welding arc directly increases ignition danger and does not provide the needed protection. So, the safe, recommended practice is to place flammable solvents in approved cabinets away from heat and ignition sources.
