TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Combustible. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames.	Powder, water spray, foam, carbon dioxide.
EXPLOSION

EXPOSURE		STRICT HYGIENE!	IN ALL CASES CONSULT A DOCTOR!
INHALATION	Headache. Nausea. Vomiting. Muscular pain. Symptoms may be delayed (see Notes).	Local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
SKIN	MAY BE ABSORBED! Redness. Pain (Further see Inhalation).	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
EYES		Face shield, or eye protection in combination with breathing protection.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
INGESTION	Abdominal pain. Nausea. Vomiting (further see Inhalation).	Do not eat, drink, or smoke during work.	Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
COLOURLESS OR PALE YELLOW LIQUID.

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance decomposes on heating and on burning producing toxic fumes including phosphorous oxides). Reacts with oxidants.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: ppm; 0.1 mg/m³ (skin) (ACGIH 1992-1993).

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and through the skin, by ingestion.

INHALATION RISK:
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the central nervous system and peripheral nervous system , resulting in impaired functions (paralysis). Exposure above OEL may result in permanent paralysis. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the nervous system , resulting in impaired functions and muscular paralysis.
