  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible but forms flammable gas on contact with water or damp air. Gives off irritating or toxic fumes (or gases) in a fire.  Risk of fire and explosion on contact with acids or water.  NO open flames, NO sparks and NO smoking. NO contact with acids or water.    Use special powder, dry sand. NO other agents. NO water.   

 PREVENT DISPERSION OF DUST! STRICT HYGIENE!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Sore throat. Cough. Shortness of breath. Headache. Dizziness. Nausea. Vomiting.  Use local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. 
Skin Redness. Burning sensation.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Wear protective gloves when administering first aid. 
Eyes Redness.  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. 
Ingestion Nausea. Vomiting. Diarrhoea. Abdominal pain. Headache. Convulsions. Shock or collapse. Unconsciousness.  Do not eat, drink, or smoke during work. Wash hands before eating.  Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention .

ALUMINIUM PHOSPHIDE ICSC: 0472
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
DARK GREY OR YELLOW CRYSTALS. 

Physical dangers
 

Chemical dangers
Decomposes on contact with water. This produces highly flammable and toxic gases (phosphine see ICSC 0694). 

Formula: AlP
Molecular mass: 58
Melting point: >1000°C
Relative density (water = 1): 2.9
Solubility in water: reaction 


EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. Inhalation of decomposition products (phosphine) may cause lung oedema. See Notes. The substance may cause effects on the cardiovascular system, nervous system and respiratory tract. This may result in impaired functions and respiratory failure. Exposure could cause death. 

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly. Hydrolysis in atmospheric moisture or perspiration may yield gaseous phosphine which can be inhaled. 

Effects of long-term or repeated exposure
 


Occupational exposure limits
 

ENVIRONMENT
The substance is toxic to aquatic organisms. 

NOTES
Commercial formulations for fumigations usually contain 57% of active ingredient.
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.
Do NOT take working clothes home.
Also consult ICSC 0694 for Phosphine.
