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.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Do NOT wash away into sewer. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Personal protection: P2 filter respirator for harmful particles.	T+ Symbol N Symbol R: 26-37-40-41-43-50/53 S: (2-)28-36/37/39-45-60-61 UN Hazard Class: 6.1	Do not transport with food and feedstuffs. Marine pollutant.

EMERGENCY RESPONSE	SAFE STORAGE
Transport Emergency Card: TEC (R)-61GT7-III	Provision to contain effluent from fire extinguishing. Separated from food and feedstuffs.

IMPORTANT DATA

Physical State; Appearance
ODOURLESS COLOURLESS CRYSTALS.

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.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 350°C Melting point: 250-251°C Relative density (water = 1): 1.8 Solubility in water, g/100 ml at 25°C: (none) <0.01 Vapour pressure, Pa at 40°C: <1.3 Octanol/water partition coefficient as log Pow: 4.38	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.

NOTES

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.
