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

See Notes.
EXPOSURE
PREVENT GENERATION OF MISTS! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
IN ALL CASES CONSULT A DOCTOR!
•INHALATION Cough. Headache. Pupillary constriction, muscle cramp, excessive salivation. Nausea. Dizziness. Laboured breathing. Convulsions. Sweating. Unconsciousness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.
•SKIN MAY BE ABSORBED! Redness. Pain. (Further see Inhalation).
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
•EYES Redness. Pain.
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. Confusion. Diarrhoea. Shortness of breath. Vomiting. (Further see Inhalation).
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
BROWN TO YELLOW LIQUID , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating or on burning producing toxic fumes including nitrogen oxides, phosphorous oxides and sulfur oxides.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and 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 irritates the eyes and the skin. The substance may cause effects on the nervous system , resulting in convulsions, respiratory failure and death. Cholinesterase inhibitor. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Cholinesterase inhibitor; cumulative effect is possible: see acute hazards/symptoms.

PHYSICAL
PROPERTIES

Decomposes below boiling point at 140-145°C
Melting point: 0.3°C
Relative density (water = 1): 1.3
Solubility in water: none
Vapour pressure, Pa at 20°C: 0.018

ENVIRONMENTAL
DATA

The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment; special attention should be given to crustacea and honey bees. In the food chain important to humans, bioaccumulation takes place, specifically in fish.

N O T E S

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. Accothion, Metathion, Novathion, Sumithion are trade names.
