The Main Factors Of Chemical Oxygen Self Rescuer Fire
The main factors that cause the fire of chemical oxygen self rescuers are chlorate oxygen candles, potassium superoxide oxygen generators and combustibles, etc. These are important sources of danger in the use of chemical oxygen self rescuers. There are usually two situations when a chemical oxygen self rescuer catches fire -
First, in the process of wearing the self rescuer, after pulling off the sealing belt to remove the outer casing, unplug the oxygen candle starting needle, so that when the oxygen candle starts to generate oxygen, the air outlet at the bottom of the oxygen candle starting device will have sparks ejected with the high-temperature oxygen, leading to Burn the rubber hose below.
Second, during the process of carrying the self rescuer, the oxygen candle starting needle fell off for some reason, and the oxygen candle starting device started to release oxygen, and the high-temperature oxygen generated accumulated in the sealed shell, causing the pressure to rise and the internal energy to increase, making self-rescuing The combustible material in the appliance catches fire.
If the two kinds of fires are in the case of underground flammable gas exceeding the standard, it is very easy to cause an accident, especially if the self rescuer is activated after the accident occurs, it is very likely to cause a secondary accident.
