TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Not combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.

In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION Risk of fire and explosion if formulations contain flammable/explosive solvents.


EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
IN ALL CASES CONSULT A DOCTOR!
Inhalation Dizziness. Sweating. Laboured breathing. Unconsciousness. Vomiting. Pupillary constriction, muscle cramp, excessive salivation.
Ventilation (not if powder), local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention. See Notes.
Skin
Protective gloves. Protective clothing.
Rinse and then wash skin with water and soap.
Eyes
Safety spectacles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion Abdominal cramps. Diarrhoea. Headache. Nausea. Vomiting. Weakness. (Further see Inhalation).
Do not eat, drink, or smoke during work. Wash hands before eating.
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
Do NOT wash away into sewer. Sweep spilled substance into containers; 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).
Do not transport with food and feedstuffs. Marine pollutant.

CARBOFURAN ICSC: 0122
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS CRYSTALS.

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes including nitrogen oxides.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.1 mg/m^3 (ACGIH 1993).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, 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 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. Cholinesterase inhibitor. Exposure may result in death. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the immune system. Cholinesterase inhibitor; cumulative effect is possible: see acute hazards/symptoms.
PHYSICAL PROPERTIES
Melting point: 153-154C
Relative density (water = 1): 1.2
Solubility in water, g/100 ml at 25C: 0.07
Vapour pressure, Pa at 33C: 0.0027
Octanol/water partition coefficient as log Pow: 2.32
ENVIRONMENTAL DATA
This substance may be hazardous to the environment; special attention should be given to water organisms, soil organisms, honey bees and birds.
NOTES
Temperature of decomposition unknown in literature. 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. Bay 70143, Curaterr, FMC 10242, Furadan, Niagara 10242, Pillarfuran and Yaltox are trade names. If the substance is present under the form of a formulation containing hydrocarbon solvents, vomiting may not be induced. If the pesticide is formulated with an organic solvent, also consult the ICSC of the solvent used.
