Engineering Controls: Person -
related precautionary measures: Avoid substance contact. Do not inhale
vapours/aerosols. Ensure supply of fresh air in enclosed rooms. Procedures
for cleaning/absorbtion: Take up with liquid-absorbent material. Forward
for disposal. Clean up affected area. Additional notes: Render harmless:
nuetralise with diluted sodium hydroxide solution.
Personal Protection: Respirator
required when vapours/aerosols are generated. Ensure respirator is clean,
well fitting and in good working order. All respirators should comply with
Australian Standard AS 1716 and be used in accordance with AS 1715. Gloves,
face shield and goggles are also required.
Special risks: Combustible. Vapours heavier than air. Formation of
explosive mixtures possible with air. Development of hazardous vapours
possible in the event of fire. Acetic acid vapours may develop in event
of fire.
Extinguishing media: Water, CO2, foam, powder. Wash hand and face after
working with substance.
Storage and Transport:
Should be tightly closed in a
well ventilated place. Keep away from sources of ignition and heat. At
room temperature (recommendation: +15 to +25 deg C)
Spills & Disposal
Shut off all sources of ignition.
Wear appropriate protective clothing. Inform others to keep at a safe distance.
If local regulations permit, mop up with plenty of water and run to waste,
diluting greatly with running water. Otherwise absorb on an inert absorbent,
transfer to container and arrange removal by disposal company. Ventilate
area to dispel residual vapour. For large spillages, liquids should be
contained with sand or earth and both liquids and solids transferred to
salvage containers. Any residues should be treated as for small spillages.
No environmental hazard is anticipated provided that the material is handled
and disposed of with due care and attention. Chemical residues are generally
classified as special waste, and as such are covered by regulations that
vary according to location. Contact your local waste disposal authority
for advice, or pass to a chemical disposal company. Rinse out empty containers
thoroughly before returning for recycling.
Product: There are no uniform Australian Regulations for the disposal
of chemicals or residues. Chemical residues generally count as special
waste. The disposal of the latter is regulated in Australia through Commonwealth,
State, Territory or Local government laws and regulations. We recommend
that you contact either the authorities in charge or licensed waste disposal
companies that will advise you on how to dispose of special waste. Packaging:
Disposal in compliance with official regulations, Handle contaminated packaging
in the same way as the substance itself. If not officially specified differently,
non-contaminated packaging may be treated like household waste or recycled.
Fire/Explosion Hazard
Combustible. Vapours heavier than
air. Formation of explosive mixtures possible with air. Development of
hazardous vapours possible in the event of fire (Acetic acid vapours)
