TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Combustible. Liquid formulations containing organic solvents may be flammable.	NO open flames.	Use water spray, powder, foam, carbon dioxide.
EXPLOSION			In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		PREVENT DISPERSION OF DUST! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!	IN ALL CASES CONSULT A DOCTOR!
Inhalation	Nausea. Vomiting. Pupillary constriction, muscle cramp, excessive salivation.	Use local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Redness. Pain. See Inhalation.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes	Redness. Pain.	Wear safety goggles or eye protection in combination with breathing protection.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion	Abdominal cramps. Diarrhoea. Nausea. Vomiting. Pupillary constriction. Muscle cramps. Excessive salivation.	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Give a slurry of activated charcoal in water to drink. Give one or two glasses of water to drink. Refer for medical attention . See Notes.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Remove all ignition sources. Do NOT let this chemical enter the environment. Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.	Do not transport with food and feedstuffs. Marine pollutant. EC Classification Symbol: Xn, N; R: 22-40-50; S: (2)-22-24-36/37-46-61 UN Classification UN Hazard Class: 6.1; UN Pack Group: III GHS Classification

EMERGENCY RESPONSE	SAFE STORAGE
Transport Emergency Card: TEC (R)-61GT7-III.	Separated from oxidants and food and feedstuffs. Well closed. Keep in a well-ventilated room.

IMPORTANT DATA

Physical State; Appearance
ODOURLESS WHITE CRYSTALS OR SOLID IN VARIOUS FORMS.

Physical dangers

Chemical dangers
Decomposes on heating and on burning. This produces toxic fumes including nitrogen oxides. Reacts violently with strong oxidants. This generates fire and explosion hazard.

Occupational exposure limits
TLV: 5mg/m³ as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
MAK: 5 mg/m³; Peak limitation category: II(4); Skin absorption (H); (DFG 2003).

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.

Inhalation risk
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.

Effects of short-term exposure
The substance is irritating to the eyes and skin. The substance may cause effects on the nervous system. This may result in convulsions and respiratory depression. Cholinesterase inhibition. The effects may be delayed. Medical observation is indicated.

Effects of long-term or repeated exposure
Cholinesterase inhibition. Cumulative effects are possible. See Acute Hazards/Symptoms. This substance is possibly carcinogenic to humans.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Decomposes Melting point: 142°C Density: 1.2 g/cm³ Solubility in water, g/100ml at 30°C: 0.004-0.012 (very poor) Vapour pressure at 20°C: negligible Flash point: 193-202°C Octanol/water partition coefficient as log Pow: 1.59	The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment. Special attention should be given to birds and bees. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal.

NOTES

Depending on the degree of exposure, periodic medical examination is indicated.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
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.
