TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Water spray, foam, powder, carbon dioxide.
EXPLOSION Finely dispersed particles form explosive mixtures in air.
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.

EXPOSURE
PREVENT DISPERSION OF DUST!

Inhalation
Local exhaust or breathing protection.
Fresh air, rest.
Skin
Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes
Safety spectacles or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Give plenty of water to drink. Rest. Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Chemical protection suit including self-contained breathing apparatus. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place.
Do not transport with food and feedstuffs.

SIMAZINE ICSC: 0699
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALLINE POWDER

PHYSICAL DANGERS:
Dust explosion possible if in powder or granular form, mixed with air.

CHEMICAL DANGERS:
Upon heating, toxic fumes are formed.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
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 LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis.
PHYSICAL PROPERTIES
Melting point (decomposes): 225-227C
Density: 1.3 g/cm
Solubility in water: none
Vapour pressure, Pa at 20C: 8.1 x 10 exp-7
Octanol/water partition coefficient as log Pow: 2.1
ENVIRONMENTAL DATA
The substance is toxic to aquatic 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
The substance is combustible but no flash point is available in literature. 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. Card has been partly updated in October 2005. See section EU classification.
