Which configuration for hazardous fuel container storage meets all required safety criteria?

• A. In unapproved containers, vented and secured to prevent tipping, away from ignition sources.
• B. In approved containers, not vented and unsecured, away from ignition sources.
• C. In approved containers, vented and secured to prevent tipping, away from ignition sources.
• D. In approved containers, vented and secured to prevent tipping, stored near ignition sources.

Answer: (C)

The main concept here is safe storage of hazardous fuel by meeting three safeguards: use only approved containers, ensure proper venting, and secure the containers to prevent tipping while keeping them away from ignition sources. Approved containers are built to regulatory standards and can safely contain fuel without leaking. Venting is important because fuel vapors can build up pressure or escape as flammable vapors; a vented container reduces the risk of overpressure and rupture. Securing containers to prevent tipping minimizes spills, which are a major fire and environmental hazard. Keeping everything away from ignition sources further lowers the chance that vapors will ignite.

Therefore, the best configuration is using approved containers that are vented, secured to prevent tipping, and stored away from ignition sources, because it satisfies all these safety criteria. Storing in unapproved containers, not vented, or unsecured increases risk, and storing near ignition sources raises the likelihood of ignition.
