	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 water, moist air, heat or many materials.	NO open flames, NO sparks and NO smoking. NO contact with water, heat or many other substances.	Use dry powder, dry sand, carbon dioxide. NO water.

PREVENT DISPERSION OF DUST! STRICT HYGIENE!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Sore throat. Cough. Shortness of breath. Headache. Dizziness. Nausea. Vomiting. Diarrhoea.	Use local exhaust or breathing protection.	Fresh air, rest. Half-upright position. Artificial respiration may be needed. No mouth-to-mouth artificial respiration. Refer immediately for medical attention. See Notes.
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. Pain.	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.	Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention. See Notes.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT wash away into sewer. Do NOT let this chemical enter the environment. Cover the spilled material with dry earth, dry sand or plastic sheet. Sweep spilled substance into covered sealable containers. Carefully collect remainder. Then store and dispose of according to local regulations.	According to UN GHS Criteria DANGER In contact with water releases flammable gases which may ignite spontaneously Fatal if swallowed or if inhaled Toxic in contact with skin Very toxic to aquatic life Transportation UN Classification UN Hazard Class: 4.3; UN Subsidiary Risks: 6.1; UN Pack Group: I
STORAGE

ALUMINIUM PHOSPHIDE

ICSC: 0472

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance DARK GREY OR YELLOW CRYSTALS. Physical dangers Chemical dangers Decomposes on contact with water or moisture. This produces highly flammable and toxic gases (phosphine see ICSC 0694). This generates toxic, fire and explosion hazard.	Formula: AlP Molecular mass: 58 Melting point: 2500°C Relative density (water = 1): 2.9 Solubility in water: reaction

Chemical dangers
Decomposes on contact with water or moisture. This produces highly flammable and toxic gases (phosphine see ICSC 0694). This generates toxic, fire and explosion hazard.

Formula: AlP
Molecular mass: 58
Melting point: 2500°C

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, respiratory tract, liver and kidneys. This may result in impaired functions, respiratory failure, tachycardia and coma. 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

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, respiratory tract, liver and kidneys. This may result in impaired functions, respiratory failure, tachycardia and coma. 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 very toxic to aquatic organisms.

NOTES
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Do NOT take working clothes home. Consult a poison information centre or an expert for further information.
