Environmental hazards
Danger: volatile, flammable and irritating. Its vapor is mixed with air to form explosive gas. In case of high heat and open fire, it can burn or explode, and reacts violently with oxidants such as chromic acid, calcium hypochlorit e, hydrogen peroxid e, nitric aci d, silver nitrat e, perchlorate, etc., which has the risk of combustion and explosion. In the fire scene, heated containers have explosion risk. Its vapor is heavier than air, and can spread to a considerable distance at a lower place. It will ignit e in case of open fire.
Hazard prevention
Engineering control: airtight operation and enhanced ventilation. Respiratory system protection: generally, no special protection is required. Filter gas mask (half mask) can be worn in case of high concentration contact. Eye protection: wear chemical safety glasses. Body protection: wear anti-static adhesive tape anti poison clothing. Hand protection: wear general operation protective gloves (rubber gloves). Other protection: shower and change clothes after work. Keep good hygiene habits.
