TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
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!

•INHALATION Headache. Dizziness. Nausea. Weakness. Flushing of the face. Chest pain. Symptoms may be delayed (see Notes).
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. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.

SPILLAGE DISPOSAL

STORAGE

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).
Fireproof. Store in a separate building. Separated from acids, food and feedstuffs. Cool. Well closed.
Do not transport with food and feedstuffs.

PHYSICAL STATE; APPEARANCE:
COLOURLESS TO YELLOWISH, OILY LIQUID

PHYSICAL DANGERS:


CHEMICAL DANGERS:
Heating may cause violent combustion or explosion producing toxic fumes (nitrogen oxides). May explosively decompose on shock, friction, or concussion. Reacts with acids.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.05 ppm; (as TWA) (skin) (ACGIH 1999).
OSHA PEL†: C 0.2 ppm (1 mg/m3) skin
NIOSH REL: ST 0.1 mg/m3 skin
NIOSH IDLH: 75 mg/m3 See: 628966


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 , resulting in sudden lowering of blood pressure. The substance may cause effects on the blood , resulting 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. Short absence from exposure may lead to sudden death.

PHYSICAL
PROPERTIES

Boiling point: explodes at 114°C
Melting point: -22°C
Relative density (water = 1): 1.49
Solubility in water, g/100 ml at 25°C: 0.5
Vapour pressure, Pa at 20°C: 7
Relative vapour density (air = 1): 5.2
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.0
Octanol/water partition coefficient as log Pow: 1.16

ENVIRONMENTAL
DATA

The substance is harmful to aquatic organisms.

N O T E S

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.
