TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Highly flammable.
NO open flames, NO sparks, and NO smoking.
Powder , foam , 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. Use non-sparking handtools.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
STRICT HYGIENE!

 •INHALATION Confusion. Cough. Dizziness. Drowsiness. Headache. Laboured breathing. Nausea. Sore throat. Unconsciousness.
Ventilation.
Fresh air, rest. Refer for medical attention.
 •SKIN Dry skin. Redness.
Protective gloves. Protective clothing.
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 Vomiting. (See Inhalation).
Do not eat, drink, or smoke during work.
Do NOT induce vomiting. Give nothing to drink. Refer for medical attention.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Evacuate danger area! Ventilation. 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. Do NOT let this chemical enter the environment. Personal protection: self-contained breathing apparatus.
Fireproof. Separated from strong oxidants. Cool. Ventilation along the floor.

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

CHEMICAL DANGERS:
Reacts with strong oxidants causing fire and explosion hazard. Attacks some forms of plastics, rubber and coatings.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 300 ppm as TWA; (ACGIH 2004).
MAK: 500 ppm, 2400 mg/m3;
Peak limitation category: II(2); Pregnancy risk group: D;
(DFG 2008).
OSHA PEL: TWA 500 ppm (2350 mg/m3)
NIOSH REL: TWA 75 ppm (350 mg/m3) C 385 ppm (1800 mg/m3) 15-minute
NIOSH IDLH: 1000 ppm 10%LEL See: 111659


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation 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 is irritating to the eyes , the skin and the respiratory tract . Swallowing the liquid may cause aspiration into the lungs with the risk of chemical pneumonitis. Exposure to high concentrations of vapour could cause lowering of consciousness.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. The liquid defats the skin.
