LPG Combustible Gas Detector Introduction
LPG is a kind of flammable and explosive hazardous material, it is easy to spontaneous combustion, when the content of LPG in the air reaches or exceeds the explosion limit value (the explosion range of the mixture of LPG in its gasified state and air is 1.7%~9.7%), it will explode when it meets open fire, causing bad impact. Moreover, there are all kinds of safety hazards in the storage and transport of LPG, such as leakage during storage and leakage problems during transport, all of which may cause serious consequences.
Once an LPG leakage accident occurs, we should take active countermeasures. First of all, the accident unit needs to take certain evacuation and emergency measures. For example, timely evacuation of staff at the scene, rapid organisation of emergency personnel to carry out on-site crowd evacuation and basic treatment of the leakage point, and pull out a cordon at the accident site to isolate the crowd and the accident site, to carry out effective isolation, and wait for the fire department to arrive at the scene. Firefighters arriving at the scene will quickly according to the terrain, meteorology, etc., in the distance from the leakage point at least 800 metres within the implementation of a comprehensive jie strict, and delineate the cordon, set up a clear sign, in order to notify the cordon area and the surrounding personnel to quickly evacuate, and prohibit the entry of all vehicles and unrelated personnel. LPG leakage, the fear is the scene of fire, at this time, in order to eliminate the fire in the cordon area, should be immediately on the cordon area of electricity, fire in a timely manner to pinch off, to eliminate all possible triggers of fire and explosion factors. In addition, before entering the hazardous area, the ground should be sprayed wet with a water gun, which is to prevent the personnel's feet from friction with the ground, impact and other actions to produce sparks.
In order to prevent safety accidents caused by LPG leakage, we should conduct a detailed study of the leakage accidents that have occurred and understand some common precautionary measures against LPG leakage, so as to reduce the recurrence of similar accidents, which will also help the firemen to be able to take positive and effective measures in time to minimise the injuries caused by the accidents and to reduce the damages when dealing with similar accidents.
Moreover, explosion-proof combustible gas detectors should be installed in places where there is a potential risk of LPG leakage. Combustible gas detector can monitor the concentration of LPG in the factory online 24 hours a day, once the LPG leakage occurs, the concentration of the mixture of LPG and air in the air reaches or exceeds the alarm value set by the instrument, the combustible gas detector will send out acoustic and visual alarm signals, and start the linkage of protection devices, forced exhaust, forced cut off the valve and other safety and emergency measures to reduce the concentration value of the site in time, and reduce the risk of LPG leakage, so as to reduce the danger. LPG concentration value in time to reduce the probability of danger.
