TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.

Water spray, foam, powder, carbon dioxide.
EXPLOSION Risk of fire and explosion if formulations contain flammable/explosive solvents.


EXPOSURE
PREVENT DISPERSION OF DUST! AVOID ALL CONTACT! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!

•INHALATION Burning sensation.
Local exhaust or breathing protection.
Fresh air, rest.
•SKIN 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 or eye protection in combination with breathing protection if powder.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION Abdominal pain. Burning sensation.
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Refer for medical attention. See Notes.

PHYSICAL STATE; APPEARANCE:
ODOURLESS COLOURLESS CRYSTALS.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating and on burning producing toxic and corrosive fumes including hydrogen chloride (see ICSC 0163) and nitrogen oxides.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: sensitization of skin (Sh);
Carcinogen category: 3B;
(DFG 2004).


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

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 irritates the eyes, the skin and the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the kidneys and gastrointestinal tract .

ENVIRONMENTAL
DATA

This substance may be hazardous to the environment; special attention should be given to aquatic organisms. The substance may cause long-term effects in the aquatic environment.

N O T E S

If the pesticide is present under the form of a formulation containing hydrocarbon solvents, vomiting may not be induced! Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. If the substance is formulated with solvents also consult the ICSCs of these materials. Carrier solvents used in commercial formulations may change physical and toxicological properties. Bombardier, Bravo, Bravocarb, Chlorothalonil, Chlortocaffaro, Contact 75, Corbel, Daconil, Dacosoil, Exotherm, Faber, Forturf, Nopcocide, Sweep and Termil TPN are trade names. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response.
