Hazardous Chemical Information System (HCIS)

Ethylene glycol (vapour)

This exposure standard was revised as part of the Source A Updates 2005 declared by NOHSC in August 2005.

No standard should be applied without reference to Guidance on the interpretation of Workplace exposure standards for airborne contaminants.

This exposure standard has been sourced from the British Health and Safety Executive (HSE). Summaries of substances recently reviewed by the HSE are published in EH64 Summary criteria for occupational exposure limits. These can be purchased from the HSE.

Additional health effect information can be found in the hazard classification.

Identity

Chemical and Physical Properties

Ethylene glycol is a clear, colourless, odourless, viscous, hygroscopic liquid with a bittersweet taste. Its chemical and physical properties include:

Note: The low vapour pressure of ethylene glycol at room temperature usually precludes excessive exposure to the vapour. However, inhalation exposure may be a problem if ethylene glycol is handled hot or if a mist is generated by heat or by violent agitation.

Major Industrial Uses

Ethylene glycol is used as antifreeze in heating and cooling systems. Large amounts are used as a chemical intermediate in the production of ethylene glycol esters, ethers, and resinous products, particularly polyester fibres and resins.
