ABC of Safety in the Biological Sciences
PETROLEUM SPIRIT
Petroleum spirit is a mixture of paraffinic, naphthenic and
aromatic hydrocarbons.
SYNONYMS
Petroleum ether.
GENERAL PRECAUTIONS
Avoid inhalation of the vapour.
Avoid ingestion.
Keep away from heat or naked flames.
Keep away from oxidising materials.
Keep the container tightly closed.
Protect against electrostatic charges.
Wash hands thoroughly after handling.
CHARACTERISTICS
Clear, colourless, volatile liquid, mild aromatic odour.
HEALTH HAZARD DATA
Petroleum ether is a narcotic and can be absorbed into the body
by inhalation of the vapour, ingestion of the liquid or through
skin contact. It can cause polyneuritis. Prolonged contact can
be fatal. It is a flammable liquid and should not be handled or
stored close to heat or a naked flame. The vapours are heavier
than air and can travel for a considerable distance along the
ground to a source of ignition and flash back.
TREATMENTS
Skin immediately remove contaminated clothing and wash the
affected area with soap or mild detergent and large amounts of
water until all evidence of the chemical has been removed
(approximately 15 minutes). Wash contaminated clothing before
reuse.
Eyes immediately wash the affected eye with large amounts of
water until all evidence of the chemical has been removed
(approximately 15 minutes). If irritation or pain persist seek
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. If signs of narcosis develop seek immediate
medical attention.
Ingestion wash out the mouth thoroughly with water and give
water to drink. Do not induce vomiting. Seek immediate medical
advice.
INCOMPATIBILITY
Petroleum spirit is incompatible with oxidising agents.
STORAGE
Store in a cool, dry, well ventilated atmosphere away from heat
or naked flames and oxidising agents.
HANDLING
Use a fume hood to minimise exposure to this substance. Wear
protective clothing. A long sleeved laboratory coat or gown,
rubber gloves, safety goggles and a face mask as a minimum
standard.
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 leak: 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.
