Most dog owners have heard of ethylene glycol since it is a poison and canines are attracted to it because of its sweet taste. If you watch Dateline or 48 hours you have heard of ethylene glycol since it is one of the ways you can poison your husband of wife. It is also a component of anti-freeze and is the green coolant that you put in your car.
In addition to these everyday encounters, this chemical is used heavily in industry. According to the American Chemistry Council, “it is used in many commercial and industrial applications including antifreeze and coolant. Other important uses of ethylene glycol include heat transfer fluids used as industrial coolants for gas compressors, heating, ventilating, and air-conditioning systems, and ice skating rinks. Ethylene glycol also is used as a raw material in the production of a wide range of products including polyester fibers for clothes, upholstery, carpet and pillows; fiberglass used in products such as jet skis, bathtubs, and bowling balls; and polyethylene terephthalate resin used in packaging film and bottles. “
Ethylene glycol can enter the body when it is ingested directly or when materials that contain it are ingested. Dermal exposure is also a significant route of entry. Persons who work with this chemical may also be exposed to ethylene glycol as a vapor. Short term exposure from ingestion can cause vomiting, drowsiness, coma, respiratory failure, convulsions, cardiopulmonary effects, and kidney and central nervous system damage. Vapors can irritate the eyes, throat, and nose. Breathing large concentrations of the vapor can cause effects similar to those affecting the skin.
Strict safety protocols and regulatory guidelines are required to minimize the chemical’s industrial and environmental exposure. Tips include:
- Do not store food, eat, or drink near processes that use ethylene glycol.
- To avoid skin contact, wear personal protective equipment such as gloves and clothing that are appropriate for ethylene glycol. (Check permeation and degradation tables.)
- Wear eye protection.
- Wash skin if exposed and remove contaminated clothing.
- Use local exhaust ventilation and respiratory protection to avoid breathing in vapors.
- Ethylene glycol is combustible and should be stored in locations away from heat and sources of ignition.
Despite its possible risks, ethylene glycol remains indispensable in various industrial sectors. Employers should provide and set up processes and procedures that control exposure, supply personal protective equipment, and safety training.
