ABC of Safety in the Biological Sciences
CREOSOTE
SYNONYMS
Wood tar fraction, wood tar.
CHARACTERISTICS
Colourless to pale yellow liquid with a smoky odour.
INCOMPATIBILITY
Heating produces toxic fumes. Creosote can react with oxidising
materials.
HEALTH HAZARD DATA
A strong eye and respiratory tract irritant and has an analgesic
affect upon skin. It is moderately toxic when ingested and can
cause irreversible changes including damage to kidneys and
liver.
HANDLING and GENERAL PRECAUTIONS
Avoid skin contact.
Avoid eye contact.
Avoid inhalation of the vapour.
Avoid ingestion.
Protect from light.
Keep the lid tightly sealed.
Keep away from heat or naked flames.
Keep away from oxidising materials.
Wash hands thoroughly after handling.
Use a well ventilated area or use a fume hood to avoid inhaling
the vapour. Wear protective clothing to avoid skin contact. A
long sleeved laboratory coat or gown, rubber gloves, safety
goggles and a face mask as a minimum standard.
TREATMENTS
Skin remove contaminated clothing and immediately wash the
affected area with large amounts of water until all evidence of
the chemical has been removed (approximately 15 minutes). Swab
the affected area with glycerol for at least 10 minutes. If
irritation or numbness persist seek medical attention.
Eyes immediately wash the affected eye with large amounts of
water until all evidence of the chemical has been removed
(approximately 15 minutes). Seek immediate medical attention.
Inhalation remove from the area of exposure to fresh air. If
breathing has ceased apply artificial respiration. Keep warm and
allow to rest. In severe cases seek immediate medical attention.
Ingestion wash the mouth with water then induce vomiting by
touching a finger to the back of the throat. Never induce
vomiting in a victim that is not conscious. Seek immediate
medical attention.
STORAGE
Store in an air tight container in a cool, dry atmosphere away
from heat and protected from the light.
DISPOSAL
WEAR:
Rubber gloves, face shield and laboratory coat. Have an all
purpose canister respirator available.
SPILLS:
A gas leak - keep the concentration of the gas below the
explosive mixture range by forced ventilation. Remove the tank
to an open area and allow dissipation to the atmosphere. Attempt
to cap the valve outlet and return the tank to the supplier.
A liquid - absorb on paper. Evaporate in an iron pan in a flame
proof fume hood then burn the paper.
A solid - sweep on to paper and place in an iron pan in a fume
hood. Burn the paper and compound.
PACKAGE LOTS:
A gas - pipe the gas into an incinerator or lower into a pit and
allow to burn.
A liquid - atomise into an incinerator. Combustion may be
improved by mixing with a more flammable solvent.
A solid - make up packages in paper or other flammable material.
Burn in the incinerator. Or the solid may be dissolved in a
flammable solvent and sprayed into a fire chamber.
