Which of the following represents a correct approach when handling flammable materials on a job site?

• A. Use non-sparking tools and ensure all equipment is properly grounded
• B. Keep all flammable liquids in open containers
• C. Store near heat sources
• D. Ignore grounding

Answer: (A)

Handling flammable materials safely hinges on eliminating ignition sources and controlling static electricity. Using non-sparking tools minimizes the chance of creating sparks if metal tools strike or interact with fittings, and ensuring equipment is properly grounded provides a path for any static buildup or stray currents to flow to earth instead of creating a spark. Together, these measures dramatically reduce the risk of ignition on a job site.

Why the other approaches are risky: keeping flammable liquids in open containers allows vapors to escape and can lead to spills or splashes that ignite easily; storing flammables near heat sources introduces a readily available ignition source; ignoring grounding leaves equipment susceptible to static discharge or electrical sparks.
