TYPES OF HAZARD
/ EXPOSURE
ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE-FIGHTING
FIRE Not combustible but forms flammable gas on contact with water or damp air.  NO contact with acids, water or oxidizing agents.  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   PREVENT DISPERSION OF DUST! STRICT HYGIENE!   
Inhalation Cough. Headache. Fatigue. Nausea. Diarrhoea. Vomiting.  Use local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Refer for medical attention. 
Skin Burning sensation.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Pain. Photophobia.  Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Nausea. Incoordination. Fatigue. Vomiting. Cough. Diarrhoea. Dizziness. Headache. Laboured breathing. Unconsciousness.  Do not eat, drink, or smoke during work. Wash hands before eating.  Give a slurry of activated charcoal in water to drink. See Notes. Refer for medical attention .

Physical dangers
 

Chemical dangers
Decomposes on heating and on contact with acids. Decomposes slowly on contact with water. This produces toxic and flammable fumes of phosphorous oxides and zinc oxides and phosphine. Reacts violently with strong oxidants. This generates fire hazard. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK (respirable fraction): 0.1 mg/m³; Peak limitation category: I(4); Germ cell mutagen group: 2; Skin absorption (H);.
MAK (inhalable fraction): 2 mg/m³; Peak limitation category: I(2); Pregnancy risk group: C; (DFG 2009). 

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

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly , especially if powdered. 

Effects of short-term exposure
The substance is irritating to the respiratory tract. The substance may cause effects on the liver, kidneys, heart and nervous system. Exposure at high levels could cause death. Inhalation of decomposition products (phosphine) may cause lung oedema. See Notes. 

Effects of long-term or repeated exposure
The substance may have effects on the nervous system. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 1100°C
Melting point: 420°C
Density: 4.6 g/cm³
Solubility in water: none, slowly decomposes 
The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment. Special attention should be given to birds and mammals. 

NOTES
Reacts violently with fire extinguishing agents such as water and carbon dioxide.
Depending on the degree of exposure, periodic medical examination is suggested.
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 by an authorized person, should be considered.
If a patient vomits after ingestion, collect the vomitus in a plastic bag to prevent emission of phosphine.
Blue-ox, Gopha-rid, Kilrat, Mous-Con, Phosvin, Ratol, Rumetan and Zinc-Tox are trade names.
