5. HEALTH HAZARD DATA
Routes of entry: Inhalation. Ingestion, Skin & Eyes.
Effects of Exposure / Symptoms:
Inhalation & Ingestion : Causes CNS depression, lung irritation, pulmonary edema, dialation of
heart, hyperemia of visceral organs, coma, convulsions, leading to death within 48 hrs. Chronic
poisoning is characterised by anemia,bronchitis, gastrointestinal disturbances and visual,
speech and motor disturbances, may result from continued exposure in low concentrations.
Emergency Treatment :
Inhalation: Remove the victim to fresh air area, apply artificial respiration of oxygen if needed.
Treatment should include recommendations listed in the oral exposure section when
Skin:
appropriate.
Immediately flush with running water for at least 20 minutes.
Eyes:
Ingestion: Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal).
Usual dose: 25 to 100 g in adults/adolescents.

6. PREVENTIVE MEASURES
Personal Protective : Avoid contact with liquid or vapour. Provide self-contained breathing
apparatus, side-copvered safety goggles I face shield, rubber hand
Equipment
gloves, protective overclothing and shoes.
Handling
: All chemicals should be considered hazardous. Avoid direct physical
contact. Use appropriate, approved safety equipment. Untrained
individuals should not handle this chemical or its container. Handling
should occur in a chemical fume hood.
Storage
: Keep in cool, dry, well ventilated area, away from heat, flame or
Chddisers.
Precautions
:
7. EMERGENCY / FIRST AID MEASURES
FIRE:
Fire Extinguishing Media : CO2, dry chemical powder, water spray.
Special Procedure
: Keep the containers cool by spraying water if exposed to heat or
flame.
Unusual Hazards
: Phosphine can explode with powerful oxidizers. The gas is heavier
than air and may travel along the ground to an ignition source.
Container may explode in heat of fire
EXPOSURE: First Aid Measures:
Inhalation: Remove the victim to fresh air area, apply artificial respiration of oxygen if needed.
Treatment should include recommendations listed in the oral exposure section
Skin:
when appropriate.
Immediately flush with running water for at least 20 minutes.
Eyes:
Ingestion: Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal).

8. ADDITIONAL INFORMATION / REFERENCES
A poison gas by inhalation. A very toxic gas whose effects are not completely understood.
Spontaneously flammable in air, if there is a trace of P2H4 present, burns with luminous flame.
Combines violently with oxygen and the halogens. Liberates hydrogen and forms phosphonium
salts when brought in contact with the halogen acids. Ignition or violent reaction with iodine,
metal nitrates, NO, NCl3, NO3, N2O, HNO2, K + NH3, Oxidants.
