TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Highly 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. 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. Sore throat.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest.
•SKIN Redness.
Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
•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 Nausea. Diarrhoea. Vomiting.
Do not eat, drink, or smoke during work.
Rinse mouth. Give plenty of water to drink. Refer for medical attention.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Ventilation. Remove all ignition sources. 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. Remove vapour with fine water spray. Do NOT let this chemical enter the environment. (Extra personal protection: filter respirator for organic gases and vapours.)
Fireproof. Well closed. Cool.

UN Hazard Class: 3
UN Packing Group: II
ICSC: 1417 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 mixes well with air, explosive mixtures are formed easily.

CHEMICAL DANGERS:
The substance can presumably form explosive peroxides. The substance may polymerize due to warming and under the influence of inorganic acid(s) and base(s) with fire or explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 50 ppm as TWA (ACGIH 2001).
OSHA PEL†: none
NIOSH REL: TWA 50 ppm (175 mg/m3) See Appendix C (Aldehydes)
NIOSH IDLH: N.D. See: IDLH INDEX


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 , the skin and the respiratory tract .

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Boiling point: 103°C

Solubility in water, g/100 ml at 20°C: 1.4
moderate
Vapour pressure, kPa at 20°C: 3.4
Relative vapour density (air = 1): 3
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.07
Flash point: 12°C o.c.
Auto-ignition temperature: 222°C
Explosive limits, vol% in air: 1.4-7.2
Octanol/water partition coefficient as log Pow: 1.31

ENVIRONMENTAL
DATA

The substance is harmful to aquatic organisms.

N O T E S

Check for peroxides prior to distillation; eliminate if found.
