TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO contact with water.  NO water. In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION     In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water. 
 
EXPOSURE   AVOID ALL CONTACT!   
Inhalation Sore throat. Cough. Burning sensation. Shortness of breath. Laboured breathing. Symptoms may be delayed. See Notes.  Use local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. 
Skin Pain. Redness. Blisters. Skin burns.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Pain. Redness. Severe deep burns. Loss of vision.  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 Burning sensation. Shock or collapse. Abdominal pain.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Evacuate danger area! Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT wash away into sewer. Sweep spilled substance into covered sealable containers. Carefully collect remainder. Then store and dispose of according to local regulations.  Do not transport with food and feedstuffs.

IMPORTANT DATA
Physical State; Appearance
FUMING WHITE-TO-YELLOW CRYSTALS WITH PUNGENT ODOUR. 

Physical dangers
The vapour is heavier than air. 

Chemical dangers
Decomposes on heating. This produces toxic and corrosive fumes including hydrogen chloride and phosphorus oxides. Reacts violently with water and moisture. This produces phosphoric acid and hydrogen chloride. Reacts with many compounds. This generates fire and explosion hazard. Attacks many metals. This produces flammable/explosive gas (hydrogen - see ICSC 0001). Attacks plastics and rubber. 

Occupational exposure limits
TLV: 0.1ppm as TWA; (ACGIH 2004).
MAK (inhalable fraction): 1 mg/m³; Peak limitation category: I(1); Pregnancy risk group: C; (DFG 2005). 

Routes of exposure
The substance can be absorbed into the body by inhalation of its vapour and by ingestion. 

Inhalation risk
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C. 

Effects of short-term exposure
The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation may cause lung oedema. See Notes. The effects may be delayed. Medical observation is indicated. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Sublimation point: 100°C
Relative density (water = 1): 1.6
Solubility in water: reaction
Vapour pressure, Pa at 55.5°C: 133
Relative vapour density (air = 1): 7.2
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.2 
 

NOTES
Reacts violently with fire extinguishing agents such as water.
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 a person authorized by him/her, should be considered.
Card has been partly updated in October 2004 and 2005.
