EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body in hazardous amounts by inhalation, through the skin and by ingestion. Effects of short-term exposure Cholinesterase inhibition. The substance may cause effects on the nervous system. This may result in convulsions and respiratory depression. Exposure could cause death. The effects may be delayed. Medical observation is indicated.	Inhalation risk No indication can be given about the rate at which a harmful concentration of this substance in the air is reached. Effects of long-term or repeated exposure Cholinesterase inhibition. Cumulative effects are possible. See Acute Hazards/Symptoms.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body in hazardous amounts by inhalation, through the skin and by ingestion.

Effects of short-term exposure
Cholinesterase inhibition. The substance may cause effects on the nervous system. This may result in convulsions and respiratory depression. Exposure could cause death. The effects may be delayed. Medical observation is indicated.

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached.

Effects of long-term or repeated exposure
Cholinesterase inhibition. Cumulative effects are possible. See Acute Hazards/Symptoms.

OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT
The substance is very toxic to aquatic organisms. 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. Do NOT take working clothes home. 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.
