TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Extremely flammable.
NO open flames, NO sparks, and NO smoking.
Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). Do NOT use compressed air for filling, discharging, or handling.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE


•INHALATION Cough. Dizziness. Dullness. Headache. Laboured breathing. Shortness of breath. Unconsciousness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
•SKIN Redness.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
•EYES Redness.
Safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION (Further see Inhalation).
Do not eat, drink, or smoke during work.
Rinse mouth. Give a slurry of activated charcoal in water to drink. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Rest. Refer for medical attention.

PACKAGING & LABELLING

Evacuate danger area! Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. Personal protection: self-contained breathing apparatus.
Fireproof. Separated from strong oxidants. Cool.

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. The vapour mixes well with air, explosive mixtures are easily formed.

CHEMICAL DANGERS:
Reacts vigorously with oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
OSHA PEL†: TWA 100 ppm (250 mg/m3)
NIOSH REL: TWA 100 ppm (250 mg/m3) ST 150 ppm (375 mg/m3)
NIOSH IDLH: 4500 ppm See: 107313
TLV: 100 ppm as TWA, 150 ppm as STEL; (ACGIH 2004).
MAK: 50 ppm, 120 mg/m3;
Peak limitation category: II(4);
skin absorption (H);
Pregnancy risk group: C;
(DFG 2004).


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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes and the skin . The vapour is irritating to the eyes and the respiratory tract . The substance may cause effects on the central nervous system. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
