How far from a source of ignition must DOT cylinders that are not filled on site be placed?

DOT cylinders that are not filled on site must be placed at least 5 feet away from any source of ignition to ensure safety and compliance with regulations. This distance is critical because it minimizes the risk of fire or explosion in the event that a leak occurs. Sources of ignition can include open flames, sparks from electrical equipment, or even hot surfaces. The 5-foot requirement serves as a precautionary measure to create a buffer zone, thereby further protecting both personnel and property from potential hazards associated with flammable gases.

It is important to understand that the safety regulations governing the storage and handling of compressed gases aim to prevent incidents that could lead to serious injury or damage. The specified distance is a key element in these safety protocols, and adhering to it is essential for safe operations in environments where DOT cylinders are present.
