| TYPES OF HAZARD / EXPOSURE | 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. Dullness. Ataxia. Pain and tightness in the chest. Tremors. Shortness of breath. Vomiting. Convulsions.
|
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 |
|
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 take to a doctor.

| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: COLOURLESS COMPRESSED LIQUEFIED GAS PHYSICAL DANGERS: The gas is heavier than air. CHEMICAL DANGERS: The substance decomposes on heating or on burning producing toxic fumes including phosphorus oxides. Reacts violently with air, oxygen, oxidants such as chlorine and nitrogen oxides, metal nitrates, halogens and other many substances, causing fire and explosion hazard. Attacks many metals. OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.3 ppm as TWA, 1 ppm as STEL; (ACGIH 2005). EU OEL: 0.1 ppm, 0.14 mg/m³ as TWA; 0.2 ppm, 0.28 mg/m³ as STEL (EU 2006). |
ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation. INHALATION RISK: A harmful concentration of this gas in the air will be reached very quickly on loss of containment. EFFECTS OF SHORT-TERM EXPOSURE: The substance is severely irritating to the respiratory tract. Inhalation of the gas may cause lung oedema (see Notes). Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the central nervous system, cardiovascular system, heart, gastrointestinal tract, liver and kidneys , resulting in impaired functions. Exposure above the OEL may result in unconsciousness or death. The effects may be delayed. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Chronic poisoning may cause toothache, swelling of the jaw, phossy jaw, spontaneous fractures of bones and anaemia. Effects are cumulative. | ||

| NOTES | |||
|
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. Card has been partly updated in October 2005 & 2006. See sections: Occupational Exposure Limits, EU classification, Emergency Response. Card has been partially updated in August 2007: see Occupational Exposure Limits.
