Which of the following tools should be used in areas near open fuel cells to reduce ignition risk?

• A. Copper tools
• B. Non-sparking Tools
• C. Aluminum tools
• D. Wooden tools

Answer: (B)

Working near open fuel cells involves exposure to flammable vapors, so any tool could become the source of an ignition. Non-sparking tools are designed to minimize that risk by using alloys that don’t produce sparks when they strike or rub, which is crucial in these environments. This keeps the same ability to perform the task while dramatically lowering the chance of igniting vapors. Regular metal tools can spark and potentially start a fire, while wooden tools, though they don’t spark, are not ideal due to durability, potential contamination, and practical issues when performing precise maintenance around fuel systems.
