TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Combustible under specific conditions. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames.	Water spray, foam, powder, carbon dioxide.
EXPLOSION

EXPOSURE		PREVENT DISPERSION OF DUST! AVOID ALL CONTACT! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
Inhalation		Ventilation (not if powder).	Fresh air, rest. Refer for medical attention.
Skin	MAY BE ABSORBED! Redness.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
Eyes	Redness. Pain. Blurred vision.	Safety spectacles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Diarrhoea. Vomiting.	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Refer for medical attention.

CAPTAN

ICSC: 0120

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALS.

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes including sulfur oxides, nitrogen oxides, hydrogen chloride, phosgene.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (Inhalable fraction) 5 mg/mł as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans); SEN; (ACGIH 2004).
MAK not established.

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and through the skin.

INHALATION RISK:
Evaporation at 20°C 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 is irritating to the eyes and the skin.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization.

PHYSICAL PROPERTIES

Melting point (decomposes): 178°C
Relative density (water = 1): 1.74
Solubility in water, g/100 ml at 25°C: (none)

Octanol/water partition coefficient as log Pow: 2.35

ENVIRONMENTAL DATA

This substance may be hazardous to the environment; special attention should be given to aquatic organisms and soil organisms.
