Emergency overview: flammable gas, mixed with air can form an explosive mixture, in the case of heat or open flame explosion, gas is lighter than air, in indoor use and storage, leakage rises and stays on the roof is not easy to discharge, in the case of Mars will cause an explosion.
GHS risk Categories:Flammable gas 1, Pressurized gas - Compressed gas, self-reactive substance -D, specific target organ system toxicity first contact -1, severe eye injury/eye irritation -2, acute toxicity - human inhalation -1
Warning word: Danger
Hazard description: highly flammable gas; Gas under pressure, if heated can explode; Heating can cause combustion - secondary contact and organ damage; Cause severe eye irritation; Suck people to death.
Precautions:
· Precautions :- Keep away from fire sources, sparks and hot surfaces. No smoking. Use only tools that do not produce sparks - use explosion-proof appliances, ventilation and lighting. During the transfer process, the container must be grounded and connected to prevent static electricity,
- Keep the container closed
- Use personal protective equipment as required,
- Prevent gas leakage into the workplace air and avoid inhaling human gas.
- Do not eat, drink or smoke in the workplace.
- Prohibited discharge into the environment,
· Incident response
In case of fire, mist water, foam, carbon dioxide and dry powder are used to extinguish the fire.
- In case of inhalation, quickly leave the scene to a place with fresh air, keep the airway unobstructed, if breathing is difficult, give oxygen, breathing, heart stop, immediately perform cardiopulmonary resuscitation, medical treatment
· Safe storage:
- Keep containers sealed and store in a cool, ventilated warehouse. Keep away from fire and heat sources and avoid contact with oxidants. Explosion-proof lighting and ventilation facilities are adopted. Equipped with the corresponding variety and quantity of fire equipment and leakage emergency treatment equipment.
· Disposal of waste :- Disposal according to national and local regulations, or contact with the manufacturer to determine the disposal method Physical and chemical hazards: flammable, can form an explosive mixture when mixed with air, in case of heat or open fire explosion gas is lighter than air, in indoor use and storage, leakage gas rises and stays on the roof is not easy to discharge, in case of Mars will cause explosion.
Health hazards:Among them, phosphine components mainly damage the nervous system, respiratory system, heart, kidney and liver. 10mg/m exposure for 6 hours, symptoms of poisoning; At 409~846mg/m, death occurred 30min to 1h.
Acute mild poisoning, the patient has headache, fatigue, nausea, insomnia, thirst, dry nose and throat, chest tightness, cough and low fever; Moderate poisoning, patients with mild disturbance of consciousness, dyspnea, myocardial damage; Severe poisoning results in coma, convulsions, pulmonary edema and obvious myocardial, liver and kidney damage. Direct skin contact with liquid can cause frostbite. 

Environmental hazards:It can pollute the atmosphere, it can be toxic to aquatic life.
