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.
Water spray, foam, powder, carbon dioxide.
EXPLOSION Risk of fire and explosion if formulations contain flammable/explosive solvents.


EXPOSURE
PREVENT GENERATION OF MISTS! STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
IN ALL CASES CONSULT A DOCTOR!
Inhalation Pupillary constriction, muscle cramp, excessive salivation. Sweating. Nausea. Headache. Dizziness. Laboured breathing. Convulsions. Unconsciousness.
Ventilation (not if powder), local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
Skin MAY BE ABSORBED! Muscle twitching. (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. 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 Muscle twitching. Abdominal cramps. Vomiting. Diarrhoea. (Further see Inhalation).
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Give a slurry of activated charcoal in water to drink. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Rest. Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. Personal protection: chemical protection suit including self-contained breathing apparatus.
Do not transport with food and feedstuffs. Severe marine pollutant.

CARBOPHENOTHION ICSC: 0410
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance decomposes on heating or on burning producing toxic fumes including phosphorus oxides, sulfur oxides, hydrogen chloride.

OCCUPATIONAL EXPOSURE LIMITS:
TLV 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:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the nervous system, resulting in convulsions and respiratory failure. Cholinesterase inhibitor. Exposure may result in death. 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
Boiling point at 0.0013 kPa: 82C
Relative density (water = 1): 1.3
Solubility in water: none
Vapour pressure, Pa at 20C: negligible
Relative vapour density (air = 1): 11.8
Relative density of the vapour/air-mixture at 20C (air = 1): 1.00
Octanol/water partition coefficient as log Pow: 5.1
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment; special attention should be given to honey bees and birds. The substance may cause long-term effects in the aquatic environment. Avoid release to the environment in circumstances different to normal use.
NOTES
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. If the substance is formulated with solvents also consult the ICSCs of these materials. Carrier solvents used in commercial formulations may change physical and toxicological properties. Do NOT take working clothes home. Acarithion, Dagadip, Garrathion, Nephocarb, Trithion are trade names. Card has been partly updated in October 2005. See section Emergency Response.
