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

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

Answer: (D)

Keeping fuel storage away from ignition sources is essential because fuel vapors can ignite if they encounter flames, sparks, or hot surfaces. Using approved containers helps prevent leaks and container failures, venting reduces the risk of pressure buildup, and securing prevents tipping or spills. The option that places fuel in approved, vented, and secured containers but near ignition sources directly violates this safety guideline, since proximity to ignition sources increases the chance of ignition and fire. The other options show safer practices in some respects but fail in other ways (unapproved containers, or lack of venting and securing), whereas the key unsafe element here is being near ignition sources.
