Hazards and Protection.
Store in a cool, dry place. Keep container closed when not in use.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Wear appropriate safety goggles, protective clothing and gloves.
Wear a NIOSH/MSHA or European Standard EN 149 approved full-facepiece airline respirator in the positive pressure mode with emergency escape provisions.
Evacuate area and ventilate. Wear protective equipment. If required, use an inert absrobent. Sweep up and place in an appropriate container for disposal. Wash contaminated surfaces.
Above 90 C, explosive vapor/air mixtures may be formed.
Reacts with strong oxidizers. Avoid contact with acid chlorides, acid anhydrides, chloroformates and reducing agents.
When heated to decomposition it emits acrid smoke and irritating fumes.

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. In case of fire, use water, dry chemical, chemical foam, or alcohol-resistant foam.
Moderate fire hazard, when exposed to heat or flame.
Abnormally low blood pressure or elevated blood pressure may occur as a result of glycol toxicity. Rapid breathing has been reported with ethylene glycol and glycol ether ingestions. CNS depression, seizures, coma, cerebral edema, and delayed neurologic sequelae may occur following most glycol exposures. CNS symptoms are common following exposures to most glycols. Exposures to glycols have resulted in teratogenicity, specifically craniofacial and neural tube closure defects and skeletal dysplasia in animal studies.
Nausea and vomiting are frequent early findings.
Tachypnea, respiratory irritation, and pulmonary edema have been reported following exposure to glycols.
May cause irritation.
Eye irritation may occur with any of the glycols.
Do NOT induce vomiting. Allow the victim to rinse his mouth and then to drink 2-4 cupfuls of water, and seek medical advice.
Remove from exposure to fresh air immediately.
Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower lids.
