TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames, NO sparks and NO smoking.  Use water spray, powder, foam, carbon dioxide. Evacuate area, fight fires only from an explosion-resistant location. 
EXPLOSION Risk of fire and explosion. Explosive.  Prevent build-up of electrostatic charges (e.g., by grounding). Use non-sparking handtools. Do NOT expose to friction or shock.  In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water. Combat fire from a sheltered position. 
 
EXPOSURE   STRICT HYGIENE!   
Inhalation Headache. Dizziness. Nausea. Weakness. Flushing of the face. Chest pain. Symptoms may be delayed. See Notes.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin MAY BE ABSORBED! See Inhalation.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes   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 See Inhalation.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.  Do not transport with food and feedstuffs.

IMPORTANT DATA
Physical State; Appearance
COLOURLESS-TO-YELLOWISH OILY LIQUID. 

Physical dangers
 

Chemical dangers
Heating may cause violent combustion or explosion. May decompose explosively on shock, friction or concussion. On combustion, forms toxic fumes of nitrogen oxides. Reacts with acids. 

Occupational exposure limits
TLV: 0.05ppm as TWA; (skin); (ACGIH 1999). 

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 can be reached rather quickly on evaporation of this substance at 20°C. 

Effects of short-term exposure
The substance may cause effects on the cardiovascular system. This may result in sudden lowering of blood pressure. The substance may cause effects on the blood. This may result in formation of methaemoglobin. Medical observation is indicated. The effects may be delayed. 

Effects of long-term or repeated exposure
Repeated exposure leads to marked tolerance and short absence from exposure may lead to sudden death. Repeated exposure leads to marked tolerance and short absence from exposure may lead to sudden death.

NOTES
Symptoms such as chest pains or palpitations that can develop during periods away from work may be indicative of toxicity of the substance and should be reported immediately to the responsible physician.
Use of alcoholic beverages enhances the harmful effect.
Rinse contaminated clothes (fire hazard) with plenty of water.
Do NOT take working clothes home.
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.
