What is the gas flash explosion introduction

What is gas flash explosion?

Flash explosion is when a flammable gas is concentrated in a space where air does not circulate, and when it reaches a certain concentration, it will immediately explode and explode if it encounters an open flame or an electric spark. In general, only a one-time explosion occurs, and if the flammable gas can be replenished in time, it will explode multiple times.

The danger of flashing:

1. The liquefied gas is volatile and has a wide range after explosion. At normal temperature and pressure, the liquefied gas is extremely volatile, and the liquid can rapidly expand 250-300 times when it encounters air. It can be seen that when the liquefied gas leaks, it will become a large amount of gas trapped in the air and form a large-area hazardous area. .

Second, the liquefied gas fire is sudden and strong, and the fire is highly harmful. When liquefied gas is dissipated into the air, it may be burned after explosion or burned first. Both of these conditions are completed in an instant, which makes people unprepared and can cause great harm to field personnel and rescue personnel. .

How to deal with flash explosion:

1. Remove the fire;
2. Prohibit the use of electricity for production and living;
3. Close all communication tools for all field personnel;
4. evacuate personnel to a safe place;
5. Rapidly dilute and disperse liquefied petroleum gas with a water gun.
