Only trained personnel should respond to an emergency involving LPG. Other personnel should be evacuated at a safe distance located upwind;
Do not use a flame to detect a leak. Soapy water may be used to test if a LPG cylinder or connection points on the system are leaking. Use an explosion proof LPG detector to determine the presence and concentration of flammable LPG in an indoor location. Where permanently installed, LPG detectors and alarm should be visible and audible. Workers should be familiar with the alarm system and its warning sounds;
If a LPG cylinder leaks, tighten the valve, attach a tag indicating that the cylinder is damaged and contains flammable gas, and store it in a well-ventilated area. Contact the supplier for instructions on returning the LPG leaking cylinder;
In case of a fire caused by flammable gas, shut off the gas supply to extinguish the fire if it is safe to do so. Attempting to extinguish the fire without shutting off the fuel supply will not prevent the LPG from escaping and accumulating in the atmosphere at hazardous levels. The fire extinguishers provided in the area are intended to extinguish small fires near the location of the LPG cylinders or tanks;
Call both LPG supplier or a professional fire brigade.
*Note: LPG Cylinders or tank exposed to fire may vent and release the flammable gas through safety pressure relief devices.
