Hazards and Protection.
Storage
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
Handling
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.
Protection
Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Whre chemical resistant gloves. To prevent repeated or prolonged skin contact, wear impervious clothing and boots.
Respirators
Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
Small spills/leaks
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.
Stability
No data.
Incompatibilities
Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products.

Fire.
Fire fighting
Fire Extinguishing Agents Not to Be Used: Water.Fire Extinguishing Agents: Dry chemical, alcohol foam, or carbon dioxide.
Hazards
Irritating vapors and toxic gases, such as carbon dioxide and carbon monoxide, may be formed when involved in fire.
Combustion products
Irritating vapors and toxic gases, such as carbon dioxide and carbon monoxide, may be formed when involved in fire.

Exposure effects
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.
   Ingestion
Nausea and vomiting are frequent early findings.
   Inhalation
Tachypnea, respiratory irritation, and pulmonary edema have been reported following exposure to glycols.
   Eyes
Eye irritation may occur with any of the glycols.

First aid
 
   Ingestion
Ipecac induced vomiting is not recommended because of the potential for cns depression. Consider after ingestion of a potentially life-threatening amount of poison if it can be performed soon after ingestion (generally within 1 hour). Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal).
   Inhalation
Remove to fresh air. If breathing has stopped, give artificial respiration. If breathing is difficult, give oxygen.
   Skin
Remove contaminated clothing and shoes. Flush with water.
   Eyes
Flush with water for at least 15 min., lifting lids occasionally.
