TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION         FIRE FIGHTING   
FIRE Explosive. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames, NO sparks, and NO smoking. Powder, water spray, foam, carbon dioxide, Note: Evacuate area, fight fires only from an explosion-resistant location.
EXPLOSION Risk of fire and explosion. 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: cool drums, etc., by spraying with water but avoid contact of the substance with water. Combat fire from a sheltered position.
 
EXPOSURE   STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR!
Inhalation Flushing of the face. Hypotension. Dizziness. Headache. Nausea. Weakness. Blue lips or finger nails. Blue skin. Confusion. Convulsions. Unconsciousness. 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   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 take to a doctor.
Ingestion (See Inhalation). Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Give a slurry of activated charcoal in water to drink. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.

SPILLAGE DISPOSAL PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT let this chemical enter the environment. (Extra personal protection: complete protective clothing including self-contained breathing apparatus.) E Symbol

Do not transport with food and feedstuffs.


EMERGENCY RESPONSE STORAGE
  Fireproof. Store in separate building. Separated from acids, food and feedstuffs. Cool. Well closed.

IMPORTANT DATA
Physical State; Appearance
LIQUID

Physical dangers
As a result of flow, agitation, etc., electrostatic charges can be generated.

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

Occupational exposure limits
MAK: IIb (see Notes); H (DFG 2002).

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

Effects of short-term exposure
The substance may cause effects on the cardiovascular system, central nervous system and blood, resulting in impaired functions and the formation of methaemoglobin. The effects may be delayed. Medical observation is indicated.

Effects of long-term or repeated exposure
The substance may have effects on the cardiovascular system, resulting in cardiac disorders.


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point at 0.9 kPa: 139°C
Melting point: 2°C
Vapour pressure, Pa at 20°C: 0.5
The substance is harmful to aquatic organisms.

NOTES
Use of alcoholic beverages enhances the harmful effect.
Depending on the degree of exposure, periodic medical examination is suggested.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
Rinse contaminated clothes (fire hazard) with plenty of water.
MAK value not established but full documentation is available (MAK IIb).
