How long must you wait to use a cylinder after it has fallen?

When a cylinder has fallen, it is critical to allow time for any potential gas leaks to stabilize before it is used again. The recommended duration of waiting—1 hour—ensures that any residual effects from the fall are taken into consideration. During this time, the cylinder can be visually inspected for damage, ensuring that it is safe to use.

If a cylinder has fallen, there may be internal fractures, compromised valves, or other issues that could lead to unsafe operating conditions. Waiting allows for a thorough check without immediate usage, which can prevent potential accidents. It's important for safety protocols to err on the side of caution, which is why this specific time frame is established in many safety guidelines in the industry. The other durations provided do not offer sufficient time to ensure the cylinder’s integrity and safety, making 1 hour the appropriate standard.
