BENOMYL ICSC: 0382
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALLINE POWDER, WITH CHARACTERISTIC ODOUR.

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

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 10 mg/m as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol 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 irritates the skin.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization. Animal tests show that this substance possibly causes toxic effects upon human reproduction. Animal tests show that this substance possibly causes malformations in human babies.
PHYSICAL PROPERTIES
Decomposes below melting point
Solubility in water: none
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment; special attention should be given to soil organisms. This substance does enter the environment under normal use. Great care, however, should be given to avoid any additional release, e.g. through inappropriate disposal.
NOTES
Card has been partly updated in October 2005. See sections Occupational Exposure Limits, EU classification.
