|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Extremely flammable. May ignite spontaneously on contact with air. Gives off irritating or toxic fumes (or gases) in a fire. Gas/air mixtures are explosive.||NO open flames, NO sparks and NO smoking. NO contact with hot surfaces. Closed system, ventilation, explosion-proof electrical equipment and lighting.||Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with powder, carbon dioxide. In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.|
|AVOID ALL CONTACT! FIRST AID: USE PERSONAL PROTECTION. IN ALL CASES CONSULT A DOCTOR!|
|Inhalation||Headache. Dizziness. Nausea. Diarrhoea. Chest pain. Shortness of breath. Irregular heartbeat. Convulsions. Unconsciousness.||Use closed system or ventilation.||Fresh air, rest. Half-upright position. Administration of oxygen may be needed. Artificial respiration may be needed. Refer immediately for medical attention.|
|Skin||ON CONTACT WITH LIQUID: FROSTBITE.||Cold-insulating gloves. Protective clothing.||ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention .|
|Eyes||ON CONTACT WITH LIQUID: FROSTBITE.||Wear face shield or eye protection in combination with breathing protection.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|Ingestion||Wash hands before eating.|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Evacuate danger area! Consult an expert! Ventilation. Personal protection: chemical protection suit including self-contained breathing apparatus.||

|OCCUPATIONAL EXPOSURE LIMITS|
TLV: 0.05 ppm as TWA; (ceiling value): 0.15 ppm as STEL; A4 (not classifiable as a human carcinogen).
MAK: 0.14 mg/m3, 0.1 ppm; peak limitation category: II(2); pregnancy risk group: C.

|This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal.|
|Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
The technical product often ignites spontaneously at room temperature because of the presence of other phosphorus hydrides, especially diphosphine (CAS:13445-5-6) as impurities.
Odourless when pure at concentrations up to 200 ppm (278 mg/m3) (a highly toxic level).
Technical product has odour of garlic or decaying fish due to impurities.
The odour warning when the exposure limit value is exceeded is insufficient.
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor, or by an authorized person, should be considered.
