What safety measure should be taken when handling gas cylinders?

When handling gas cylinders, checking for leaks before use is essential for safety. Gas leaks can pose significant risks, including fire hazards and exposure to harmful gases. By checking for leaks, you ensure that the cylinder is secure and functioning properly, reducing the chances of accidents or injuries.

Leak detection can involve conducting a visual inspection for any obvious signs of damage and using soapy water or specific leak detection solutions that will bubble up in case of a leak. This precautionary step is critical to maintaining a safe working environment, particularly when working with flammable or toxic gases commonly stored in cylinders.

Other options present unsafe practices. Storing gas cylinders horizontally can lead to leakage and is not recommended because cylinders are designed to be stored upright. Keeping them indoors without proper ventilation can accumulate gases in case of a leak, which is hazardous. Additionally, using cylinders without regulators can create uncontrolled gas flow, which is dangerous and could result in equipment damage or personal injury.
