EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. Effects of short-term exposure The substance is irritating to the eyes.	Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. Effects of long-term or repeated exposure Repeated or prolonged contact may cause skin sensitization.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

Effects of short-term exposure
The substance is irritating to the eyes.

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization.

OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT
The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment. Special attention should be given to plants. Avoid release to the environment in circumstances different to normal use.

NOTES
The technical grade is 98% pure; dazomet is moderately stable but is sensitive to temperature > 35°C and to moisture. 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.
