  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible but forms flammable gas on contact with water or damp air.    NO contact with water, oxidizing agents or acids.    NO water, foam. In case of fire in the surroundings, use appropriate extinguishing media.  In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water. 

 AVOID ALL CONTACT!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Cough. Headache. Sore throat. Laboured breathing. Tremor. Diarrhoea. Convulsions. Vomiting.  Use local exhaust or breathing protection.  Refer for medical attention. Half-upright position. Artificial respiration may be needed. No mouth-to-mouth artificial respiration. 
Skin Redness. Pain.  Protective clothing. Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
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 See Inhalation.  Do not eat, drink, or smoke during work.  Refer for medical attention . Induce vomiting (ONLY IN CONSCIOUS PERSONS!). NO mouth-to-mouth artificial respiration.

PACKAGING
 
CALCIUM PHOSPHIDE ICSC: 1126
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
RED-BROWN CRYSTALLINE POWDER OR GREY LUMPS. 

Physical dangers
 

Chemical dangers
Reacts violently with acids, water and moist air. This produces phosphine (see ICSC 0694). This generates fire and toxic hazard. Reacts violently with strong oxidants. This generates fire and explosion hazard. 

Formula: Ca3P2
Molecular mass: 182.2
Melting point: 1600°C
Density: 2.5 g/cm³ 


EXPOSURE & HEALTH EFFECTS

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

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

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 

Effects of long-term or repeated exposure
 


Occupational exposure limits
 

ENVIRONMENT
The substance is very toxic to aquatic organisms. 

NOTES
Environmental effects from the substance have not been investigated adequately.
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.
Do NOT take working clothes home.
