TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Flammable. NO open flames, NO sparks, and NO smoking. Alcohol-resistant foam, powder, carbon dioxide.
EXPLOSION Above 25°C explosive vapour/air mixtures may be formed. Above 25°C use a closed system, ventilation, and explosion-proof electrical equipment. In case of fire: keep drums, etc., cool by spraying with water.
 
EXPOSURE      
Inhalation Sore throat. Cough. Headache. Weakness. Drowsiness. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Refer for medical attention.
Skin Dry skin. Protective gloves. Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes Redness. Pain. Safety goggles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion Sore throat. Nausea. Abdominal pain. (Further see Inhalation). Do not eat, drink, or smoke during work. Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention.

SPILLAGE DISPOSAL PACKAGING & LABELLING
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. EU classification
R: 10-66
S: (2-)23-25
Note: C
UN classification
UN Hazard Class: 3
UN Pack Group: III


EMERGENCY RESPONSE SAFE STORAGE
Transport Emergency Card: TEC (R)-30S1104 or 30GF1-III
NFPA Code: H 1; F 3; R 0
Fireproof. Separated from strong oxidants.

IMPORTANT DATA
Physical State; Appearance
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

Physical dangers
The vapour mixes well with air.

Chemical dangers
Reacts violently with strong oxidants causing fire and explosion hazard. Attacks some forms of resins.

Occupational exposure limits
TLV: 50 ppm as TWA; 100 ppm as STEL; (ACGIH 2004).
MAK: 50 ppm, 270 mg/m³; Peak limitation category: I(1); Pregnancy risk group: D; (DFG 2006).

Routes of exposure
The substance can be absorbed into the body by inhalation of its vapour 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 vapour is irritating to the eyes and the respiratory tract. Exposure to high concentration of vapours may result in unconsciousness.

Effects of long-term or repeated exposure
The liquid defats the skin.
