(2) Health hazards. Contact causes eye irritation, burning sensation, dry mouth and nose, fatigue, headache, nausea and so on. Poisoning can affect the liver, central nervous system and cardiovascular system, can cause skin ulcers.
(3) Hazardous properties. Decomposed by high heat to produce toxic corrosive fumes. (4) Emergency treatment of leakage. Isolate the leaking contaminated area and restrict access. Cut off the source of ignition. It is recommended that emergency personnel wear dust masks (full face masks) and anti-virus clothing. Small amount of leakage: collect in dry, clean, covered container with clean shovel. Large amount of leakage: collect for recycling or transport to waste disposal site for disposal.
(5) Fire extinguishing methods. Firefighters shall wear gas masks and full body firefighting suits to extinguish the fire upwind. Extinguishing agents: mist water, foam, dry powder, carbon dioxide, sand, etc.This article comes from: https://fireworkslit.com/Fireworkslit-https://fireworkslit.com/materials-commonly-used-in-fireworks-22-properties-of-hexachlorobenzene/ This article comes from: https://fireworkslit.com/Fireworkslit-https://fireworkslit.com/materials-commonly-used-in-fireworks-22-properties-of-hexachlorobenzene/
