TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Highly flammable.
NO open flames, NO sparks, and NO smoking.
AFFF, alcohol-resistant foam, powder, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Use non-sparking handtools.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT GENERATION OF MISTS!

•INHALATION Cough. Dizziness. Drowsiness. Headache. Nausea. Sore throat. Unconsciousness. Weakness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
•SKIN Dry skin.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
•EYES Redness. Pain.
Safety goggles, 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
Do not eat, drink, or smoke during work.
Rinse mouth. Give plenty of water to drink.

PACKAGING & LABELLING

Evacuate danger area! 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 wash away into sewer. Personal protection: complete protective clothing including self-contained breathing apparatus.
Fireproof. Separated from strong oxidants. Cool. Well closed.

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
The vapour is heavier than air and may travel along the ground; distant ignition possible.

CHEMICAL DANGERS:
Heating may cause violent combustion or explosion. The substance decomposes under the influence of UV light , acids , bases . Reacts with strong oxidants , bases or acids . Attacks aluminium and plastics.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 400 ppm as TWA; (ACGIH 2004).
MAK: 400 ppm, 1500 mg/m3;
Peak limitation category: I(2); Pregnancy risk group: C;
(DFG 2004).
OSHA PEL: TWA 400 ppm (1400 mg/m3)
NIOSH REL: TWA 400 ppm (1400 mg/m3)
NIOSH IDLH: 2000 ppm 10%LEL See: 141786


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour.

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 is irritating to the eyes and the respiratory tract . The substance may cause effects on the central nervous system. Exposure far above the OEL may result in death.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin.
