(1) Ignition and explosion characteristics and fire protection

Combustibility: combustibility

Grade of construction fire risk: B

Flash point (° C) : Meaningless

Spontaneous combustion temperature (℃) : meaningless

Lower explosive limit (V%) : Meaningless

Upper explosion limit (V%) : Meaningless

Hazardous characteristics: Exposure to organic matter may cause burning hazard. Explosion may occur when heated sharply. Can with concentrated sulfuric acid, fuming nitric acid. React violently, even explode. Strong oxidizing agent. Decomposition occurs when exposed to heat or light [decomposition occurs at 100℃].

Fire extinguishing method: mist water, sand. It fuels the fire. If the substance or contaminated fluid enters the waterway, notify downstream users with potential water contamination, and notify local health and fire officials and pollution control authorities.

(2) Precautions for storage and transportation

Precautions for storage and transportation: Store in a cool and ventilated warehouse. Keep away from fire and heat. Protect from direct sunlight. Keep the container airtight. It should be stored separately from inflammable and combustible materials and acids. Avoid mixed storage and transportation. Should not be large or long lasting. Load and unload lightly during handling to prevent damage to packaging and containers. Do not shock, impact or friction.

(3) Emergency treatment of leakage

Leak disposal: Isolate the contaminated area of the leak and set warning signs around it. Emergency personnel are advised to wear gas masks and chemical protective suits. Do not make the leakage and combustible substances (wood, paper, oil, etc.) contact, do not directly contact the leakage, wash with a lot of water, diluted water into the waste water system or carefully sweep up, add water (3%), with sulfuric acid to adjust the pH value to 2, then by

Gradually add excess sodium bisulfite and discard after reaction. Such as a large amount of leakage, collection and recycling or harmless disposal after waste.
