|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE FIGHTING|
|FIRE||Extremely flammable. Gives off irritating or toxic fumes (or gases) in a fire.||NO open flames, NO sparks and NO smoking. NO contact with hot surfaces.||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.|
|EXPLOSION||Gas/air mixtures are explosive.||Closed system, ventilation, explosion-proof electrical equipment and lighting.||In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.|
|EXPOSURE||STRICT HYGIENE!||IN ALL CASES CONSULT A DOCTOR!|
|Inhalation||Cough. Nausea. Burning sensation. Diarrhoea. Abdominal pain. Headache. Dizziness. Lethargy. Incoordination. Chest pain. Chest tightness. Tremor. Shortness of breath. Vomiting. Convulsions.||Use breathing protection.||Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer 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||Wear safety goggles 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.|
|PACKAGING & LABELLING|
|Evacuate danger area! Consult an expert! Ventilation. Personal protection: chemical protection suit including self-contained breathing apparatus.||

The technical product often ignites spontaneously at room temperature because of the presence of other phosphorus hydrides (especially P_2H_4) as impurities.
Odourless when pure at concentrations up to 200 ppm, a highly toxic level.
Technical product has a garlic-like odour due to impurities.
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 is therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
The odour warning when the exposure limit value is exceeded is insufficient.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
