EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion. Effects of short-term exposure The substance may cause effects on the nervous system. This may result in convulsions and respiratory failure. Exposure above the OEL could cause death. Cholinesterase inhibition. The effects may be delayed. Medical observation is indicated.	Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying. Effects of long-term or repeated exposure Cholinesterase inhibition. Cumulative effects are possible. See Acute Hazards/Symptoms.

Cholinesterase inhibition. Cumulative effects are possible. See Acute Hazards/Symptoms.

OCCUPATIONAL EXPOSURE LIMITS
TLV: 0.05 mg/m³, as TWA; (skin); A4 (not classifiable as a human carcinogen); BEI issued

ENVIRONMENT
The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment. Special attention should be given to birds and bees. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal.

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 solvent(s) also consult the card(s) (ICSC) of the solvent(s). Carrier solvents used in commercial formulations may change physical and toxicological properties. Do NOT take working clothes home.
