When a gas leak is detected while using a gas boiler, what emergency measures should be taken?

When a gas leak is detected while using a gas boiler, the following emergency measures should be immediately taken to ensure personal safety and control the leakage situation:

Quickly locate and close the main gas valve of the boiler to cut off the gas supply and prevent further leakage.If there is a flame near the valve, use a wet towel or wet clothing to wrap your hand, and try to close the valve to avoid hand injuries.

If the gas leak occurs in the boiler room or nearby areas, immediately cut off the power supply to the area to prevent electrical equipment from generating sparks that could trigger an explosion.Ventilate the Area:Open doors and windows to ensure indoor air circulation, reducing the concentration of gas inside and lowering the risk of explosion.Avoid turning on or off any electrical equipment, including lights, exhaust fans, etc., to prevent the creation of sparks.

Quickly evacuate the personnel from the leakage site and surrounding areas, and prevent unauthorized personnel from approaching to ensure safety.Establish a warning zone to prevent others from inadvertently entering the hazardous area.

Ensure your own safety first, then use a phone outside the danger area to call the local gas company's emergency center or dial 110 to report the leak and request professional assistance.Provide the dispatcher with details about the leak's exact location, the amount of leakage, and whether there are any injuries.

Prohibit Open Flames:Strictly prohibit smoking, the use of open flames, or any operations that may generate sparks in and around the leak site to prevent an explosion.Wait for Professional Assistance:Do not attempt to enter the leakage site or fix the leak on your own before professionals arrive.Cooperate with the professionals, providing necessary assistance and information.

To prevent gas leaks, users should regularly inspect the gas boiler, its pipes, valves, and other equipment for integrity and proper sealing, and promptly replace any aged or damaged components. Ensure that the environment where the gas boiler is used is well-ventilated and free from flammable or explosive materials. Users should also be knowledgeable about the correct operation of the gas boiler and emergency response procedures so they can act quickly and effectively to protect themselves and others in the event of a leak or other emergency situation.
