What should be kept readily available when working with compressed gases?

When working with compressed gases, it is essential to have emergency contact information and fire extinguishers readily available. This is due to the potential hazards associated with compressed gases, including the risk of fire and other emergencies. Having fire extinguishers on hand ensures that any accidental ignition can be promptly dealt with, helping to prevent a small fire from escalating. Emergency contact information is crucial for quickly obtaining assistance or reporting accidents to the appropriate authorities.

In contrast, while a first aid kit is important in many settings, it is not specific to the immediate needs when dealing with compressed gases as effectively as fire safety measures are. Extra cylinders and spare parts may be useful in certain situations but do not address immediate emergency response needs. Personal entertainment devices are irrelevant in the context of safety and emergency preparedness when handling potentially hazardous materials.
