Which statement about transporting a propane cylinder during vehicle transport is correct?

• A. It should be laid flat to prevent rolling.
• B. It should be secured upright in a ventilated area to reduce venting risk and allow any released gas to disperse.
• C. It should be placed in the trunk with the lid closed.
• D. It should be kept in direct sunlight.

Answer: (B)

Transporting a propane cylinder safely centers on how the cylinder is positioned and how it can vent any gas if a leak occurs. Keeping the cylinder upright and secured prevents damage to the valve and keeps the protective relief system aligned properly. When the cylinder is upright, any gas that vents does so through the valve system without being blocked or stressed by pressure on the valve stem, and the securing prevents it from rolling and potentially causing damage or a short incident during movement. Ventilation matters because propane is heavier than air and can pool in low spots inside a vehicle if there’s a leak. A well-ventilated area allows any released gas to disperse quickly, reducing the chance that leaked gas accumulates in a confined space where it could ignite. The combination of upright positioning, being secured, and having good airflow minimizes both the physical risk to the cylinder and the risk of gas buildup. Other options fail for practical and safety reasons: laying the cylinder flat can put stress on the valve and interfere with venting; placing it in a closed trunk creates a confined space where leaked gas could accumulate; and keeping it in direct sunlight raises temperature and pressure inside the cylinder, increasing overall risk.
