Which option describes a storage setup that clearly violates the requirement to vent containers?

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

Answer: (B)

Vent containers to prevent pressure buildup and vapor accumulation. When containers are vented, any pressure or fumes can escape safely, reducing the risk of rupture or flare-ups. The described setup with approved containers that are not vented defeats this safety step, creating a hazardous condition where pressure can build up inside and vapors can accumulate. That’s why it clearly violates the venting requirement. The other scenarios either meet the venting rule (vented) or fail safety in different ways (unapproved containers or containers that are not secured), but they don’t specifically violate the venting requirement.
