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

EXPOSURE		STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!	IN ALL CASES CONSULT A DOCTOR!
•INHALATION	Pupillary constriction, muscle cramp, excessive salivation. Sweating. Nausea. Dizziness. Convulsions. Unconsciousness. Vomiting.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Refer for medical attention.
•SKIN	MAY BE ABSORBED! (Further see Inhalation).	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
•EYES	Blurred vision.	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 cramps. Nausea. Vomiting. Diarrhoea. (See Inhalation).	Do not eat, drink, or smoke during work. Wash hands before eating.	Induce vomiting (ONLY IN CONSCIOUS PERSONS)! Rest. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
COLOURLESS OR PALE YELLOW LIQUID.

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic and corrosive fumesincluding phosphoric acid and phosphorus oxides. Reacts violently with strong oxidants causing fire and explosion hazard. Attacks iron, stainless steel, brass, some forms of plastics, rubber and coatings.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.01 ppm as TWA; (skin); A4; SEN; BEI issued; (ACGIH 2004).
MAK: 0.01 ppm, 0.093 mg/mł; H;
Peak limitation category: II(2);
(DFG 2004).
OSHA PEL: TWA 0.1 mg/m³ skin
NIOSH REL: TWA 0.01 ppm (0.1 mg/m³) ST 0.03 ppm (0.3 mg/m³) skin
NIOSH IDLH: 4 ppm

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

INHALATION RISK:
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the nervous system , resulting in convulsions, respiratory failure. Cholinesterase inhibitor. Exposure far above OEL may result in death. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Decomposes below boiling point at 300°C
Melting point: 6.9°C
Relative density (water = 1): 1.25
Solubility in water:
miscible

Vapour pressure, Pa at 21°C: 0.38
Flash point: 79.5°C o.c.

ENVIRONMENTAL
DATA

The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment; special attention should be given to birds. Avoid release to the environment in circumstances different to normal use.

N O T E S

Depending on the degree of exposure, periodic medical examination is suggested. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Carrier solvents used in commercial formulations may change physical and toxicological properties. Do NOT take working clothes home. Apavinfos, Duraphos, Fosdrin, Gesfid and Phosdrin are trade names. Card has been partly updated in October 2004. See sections Occupational Exposure Limits, EU classification, Emergency Response.
