2. It is flammable, heated to 100, that is, it decomposes violently, and can detonate when exposed to fire or heat or shock. It will react violently when in contact with reducing agents, accelerators, organic matter, combustibles, etc., and there is a risk of combustion. It is highly corrosive.
3. The flash point of peracetic acid is 41, which is organic peroxide and belongs to secondary flammable liquid; Therefore, it has the fire hazard of organic peroxides and flammable liquids.
1) It is highly flammable. It is flammable, the ignition energy required is very small, and it is easy to cause combustion or ** when it encounters open flames and electrostatic sparks during storage and use; At the same time, it can react with combustibles and produce enough heat, and the oxygen released after its decomposition can strongly support combustion, which can eventually lead to spontaneous combustion, combustion and occurrence**.
2) Vapor has a strong ** property. Due to its strong volatility, the volatile vapor can form a flammable mixture with air at any concentration, which can cause combustion in case of open flame.
3) Thermal expansion. When it is used in a closed container, if the storage environment temperature is high or affected by heat, vibration and other factors, it can lead to an increase in the vapor pressure in the container, and when the limit pressure of the container is exceeded, it will cause the container to burst or **, and liquid burns to staff or fire accidents.
4) Mobility. Mobility increases its fire hazard, and once a leak occurs, it will flow along the terrain and even into the pipe ditch, etc., and when a fire occurs, it will cause the expansion and spread of the fire.
5) Electrostatic. In the process of perfusion, transportation, transportation, activity and handling, it is easy to produce static electricity, and when the static electricity accumulates to a certain extent, it will be discharged, causing fire or **.
6) It is extremely sensitive to heat, impurities, impact, pH, strong light and vibration, friction, etc., and is prone to combustion or electric sparks by impact, heat and electric sparks; Heating to 110 is violently decomposed**, and the sensitivity of ** occurs when it is shaken.
7) In the process of storage, transportation and use, once mixed with organic matter, flammable matter, acid and alkali, reducing agent and inorganic oxidant, it can react violently, release a large amount of oxygen, heat and water vapor and cause combustion or **.
