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.
Foam, powder, carbon dioxide.
EXPLOSION The explosion hazard will depend on the solvent used in the formulation or on the characteristics of the dust.


 
EXPOSURE
PREVENT GENERATION OF MISTS! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
IN ALL CASES CONSULT A DOCTOR!
INHALATION Convulsions. Dizziness. Nausea. Unconsciousness. Vomiting. Pupillary constriction, muscle cramp, excessive salivation.
Ventilation (not if powder), 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.
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 if powder.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
INGESTION Abdominal cramps. Diarrhoea. Laboured breathing. Nausea. Unconsciousness. Vomiting. Blurred vision.
Do not eat, drink, or smoke during work.
Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Do NOT wash away into sewer. Sweep spilled substance into sealablecontainers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. (extra personal protection: complete protective clothing including self-contained breathing apparatus).
Separated from food and feedstuffs. Keep in a well-ventilated room.
Do not transport with food and feedstuffs.

PHYSICAL STATE; APPEARANCE:
COLOURLESS CRYSTALS

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating above 200°C producing toxic and corrosive fumes including nitrogen oxides, phosphorous oxides, sulfur oxides. The substance decomposes under influence of acids and bases (hydrolysis).

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: ppm; 0.2 mg/m3 (skin) (ACGIH 1991-1992).


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

INHALATION RISK:
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the nervous system , resulting in convulsions, respiratory failure. Exposure at high level may result in death. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Cholinesterase inhibitor; cumulative effect is possible: see acute hazards/symptoms.
PHYSICAL
PROPERTIES
 Melting point: 73-74°C
Relative density (water = 1): 1.44
Solubility in water: none 		Vapour pressure, Pa at 20°C: <10-3
Octanol/water partition coefficient as log Pow: 2.75
ENVIRONMENTAL
DATA
 This substance may be hazardous to the environment; special attention should be given to fish.
NOTES
The technical material is a brown waxy solid. Depending on the degree of exposure, periodic medical examination is indicated. The symptoms of acute intoxication do not become manifest until 30 minutes to 1-2 hours. 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. Guthion and gusathion M are trade names.
