TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Extremely flammable.
NO open flames, NO sparks, and NO smoking.
Foam, dry powder, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting. 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. Drowsiness. Sore throat. Vomiting. Unconsciousness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest.
•SKIN Dry skin.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
•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 (See Inhalation).
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Refer for medical attention.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Evacuate danger area! Remove all ignition sources. 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 wash away into sewer. Personal protection: filter respirator for organic gases and vapours.
Fireproof. Separated from oxidants. Cool. Store in an area without drain or sewer access.

UN Hazard Class: 3
UN Packing Group: II
ICSC: 0490 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

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, and may accumulate in low ceiling spaces causing deficiency of oxygen.

CHEMICAL DANGERS:
Reacts violently with oxidants causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 50 ppm as TWA; (ACGIH 2004).
MAK not established.


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 mildly irritating to the eyes and the respiratory tract . Swallowing the liquid may cause aspiration into the lungs with the risk of chemical pneumonitis. Exposure at high levels could cause lowering of consciousness.

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

Solubility in water, g/100 ml at 20°C: 0.005
Vapour pressure, kPa at 20°C: 18.7
Relative vapour density (air = 1): 2.9
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.4
Flash point: -26°C c.c.

Explosive limits, vol% in air: 1.2-6.9
Octanol/water partition coefficient as log Pow: 3.39

ENVIRONMENTAL
DATA

The substance is toxic to aquatic organisms.

N O T E S

High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Check oxygen content before entering area.
Transport Emergency Card: TEC (R)-30S2370

NFPA Code: H1; F3; R0.
