Which statement describes a clearly unsafe storage scenario for hazardous fuel containers at the dock?

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

Answer: (D)

The safety principle here is that hazardous fuel storage on the dock must minimize ignition risk by using approved, vented containers that are secured to prevent tipping, and by keeping them away from any ignition sources. The clearly unsafe scenario is storing even vented, secured, approved containers near ignition sources. Fuel vapors can ignite when they encounter a spark, flame, or hot surface, and proximity to ignition sources dramatically increases that risk. Venting is important to release any pressure and prevent container rupture, while securing prevents spills from tipping. Being away from ignition sources reduces the chance of ignition. The other factors matter too—unapproved containers are risky because their construction is not guaranteed to be safe, and not vented or unsecured containers are prone to leaks and explosions—but the defining unsafe condition in this case is the near ignition sources.
