What is the primary safety role of an approved cart when moving gas cylinders?

• A. To identify the gas inside the cylinder.
• B. To regulate gas flow during transport.
• C. To allow fast speeds.
• D. To safely transport cylinders, keeping them upright and secured with caps on when necessary.

Answer: (D)

An approved cylinder cart is there to move gas cylinders safely by keeping them upright and securely restrained during transport. This upright position prevents the valve from being damaged or the cylinder from tipping, rolling, or leaking if bumped, while the restraints stop movement that could cause injuries. Keeping the protective caps on helps shield the valve stem from impact and contamination as the cylinders are moved. Identifying the gas, regulating flow, or speeding transport aren’t the cart’s safety roles, which focus on safe handling and secure, stable transport.
