Which action best reduces the risk of fire when wires are routed near fuel lines?

• A. Route above lines and secure to prevent chafing
• B. Run parallel to lines for cooling
• C. Use thin insulation
• D. Do nothing

Answer: (A)

Keep electrical wiring away from fuel lines and secure it to prevent movement. When wires rub against fuel lines, the insulation can wear through from vibration, creating exposed conductors or arcing. In the presence of fuel vapors and heat, this can ignite a fire. Routing wires above the lines provides clearance, and securing them prevents chafing and shifting that would expose the conductors. Routing parallel to lines for cooling doesn’t reduce abrasion risks and can still position wiring where leaks or heat could affect it. Using thin insulation offers less protection against abrasion and heat, increasing fire risk. Doing nothing leaves the hazard completely unaddressed.
