TYPES OF
HAZARD /
EXPOSURE 		ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use water spray, foam, powder, carbon dioxide. 
EXPLOSION Risk of fire and explosion on confinement and exposure to high temperatures.    Combat fire from a sheltered position. 
 
EXPOSURE   AVOID ALL CONTACT! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Sweating. Headache. Laboured breathing. Nausea. Vomiting. Fever. Convulsions. Unconciousness. Cyanosis.  Use ventilation (not if powder), local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. 
Skin EASILY ABSORBED! Redness. Further see Inhalation.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer immediately for medical attention. 
Eyes Redness. Pain.  Wear face shield 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 pain. Further see Inhalation.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Rest. Give a slurry of activated charcoal in water to drink. Refer immediately for medical attention. 

SPILLAGE DISPOSAL
 		PACKAGING & LABELLING
Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. 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.

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic fumes including nitrogen oxides. The solution in water is a weak acid. Attacks many metals in the presence of water. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK (not established):. 

Routes of exposure
The substance can be absorbed into the body by inhalation, 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. The substance may cause effects on the central nervous system. Exposure at high levels could cause death. 

Effects of long-term or repeated exposure
The substance may have effects on the hematopoetic system. May cause reproductive toxicity in humans.

Octanol/water partition coefficient as log Pow: 3.69   		The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment. Special attention should be given to bees, birds and mammals. 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
Temperature of decomposition is unknown in the literature.
Depending on the degree of exposure, periodic medical examination is suggested.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
If the substance is formulated with solvents also consult the ICSCs of these materials.
Do NOT take working clothes home.
