Which option clearly violates the rule by placing containers near ignition sources?

• A. Approved containers, vented, secured to prevent tipping, away from ignition sources.
• B. Unapproved containers, vented, secured to tipping, away from ignition sources.
• C. Approved containers, not vented, unsecured, away from ignition sources.
• D. Approved containers, vented, secured to prevent tipping, near ignition sources.

Answer: (D)

The key idea is keeping fuel containers away from ignition sources to prevent vapors from igniting. Fuel vapors can ignite if they encounter heat, sparks, or flames, so containers must be placed where they won’t be exposed to those ignition sources, be approved, vented to release vapors, and secured to avoid tipping.

The option that clearly violates the rule places containers near ignition sources, which directly increases the chance that any vapors or spills could ignite. Even though the container is approved, vented, and secured to prevent tipping, being near a heat source or spark is unsafe and defeats the safety objective.

The other options either keep containers away from ignition sources, or have other unsafe features (not vented or unsecured), but they don’t violate this specific rule about proximity to ignition sources.
