TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames, NO sparks, and NO smoking. NO contact with flammable substances. NO contact with air. NO contact with hot surfaces. NO contact with oxidants, halogens, sulfur and strong alkalis.	Water spray, wet sand.
EXPLOSION			In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		AVOID ALL CONTACT!	IN ALL CASES CONSULT A DOCTOR!
INHALATION	Burning sensation. Unconsciousness. Symptoms may be delayed (see Notes).	Ventilation.	Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.
SKIN	Skin burns. Pain (further see Inhalation).	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention. Wear protective gloves when administering first aid. Keep contaminated clothes and shoes under water or sand/earth; do NOT use soap for cleaning.
EYES	Pain. Loss of vision. Severe deep burns.	Safety goggles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
INGESTION	Abdominal cramps. Unconsciousness (further see Inhalation).	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Give nothing to drink. Rest. Refer for medical attention.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Evacuate danger area! Consult an expert! cover spilled substance with wet sand or earch. Do NOT wash away into sewer. Sweep spilled substance into containers then remove to safe place (extra personal protection: complete protective clothing including self-contained breathing apparatus).

Fireproof. Separated from strong oxidants, food and feedstuffs. Cool. Keep under water.

Airtight. Unbreakable packaging; put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs.

PHYSICAL STATE; APPEARANCE:
WHITE TO YELLOW TRANSPARENT CRYSTALLINE SOLID WITH WAXY APPEARANCE. TURNS DARK ON EXPOSURE TO LIGHT.

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance may spontaneously ignite on contact with air producing toxic fumes (phosphorus oxides). Reacts violently with oxidants, halogens and sulfur, with fire and explosion hazard. Reacts with strong alkalies, giving off toxic gas (phosphine).

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV not established.

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour and by ingestion.

INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation of vapour may cause lung oedema (see Notes). The substance may cause effects on the kidneys, liver. Exposure may result in death. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the bone , resulting in bone degeneration.

PHYSICAL
PROPERTIES

Boiling point: 280°C
Decomposes below melting point at 44°C
Relative density (water = 1): 1.83
Solubility in water: none

Vapour pressure, Pa at 20°C: 3.5
Relative vapour density (air = 1): 4.42
Auto-ignition temperature: 30°C

ENVIRONMENTAL
DATA

NOTES

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 spray, by a doctor or a person authorized by him/her, should be considered.
