Hazards and Protection.
Keep away from heat and flame. Keep container closed when not in use. Store in a cool, dry, well-ventilated area away from incompatible substances.
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use only in a well ventilated area. Avoid contact with eyes, skin, and clothing. Avoid contact with heat, sparks and flame. Avoid ingestion and inhalation.
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Wash area with soap and water. Clean up spills immediately, using the appropriate protective equipment. Provide ventilation.
Stable under normal temperatures and pressures.
Strong acids, strong oxidizing agents, acid chlorides, strong reducing agents and acid anhydrides.
Carbon monoxide, irritating and toxic fumes and gases, carbon dioxide, acrid smoke and 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. Extinguishing media: Use foam, dry chemical, or carbon dioxide. For large fires, use water spray or fog.
Slightly flammable. Combustion requires preheating. Moderate hazard.
TLV: 25 ppm; 121 mg/m3 ceiling (ACGIH 1995-1996). NIOSH REL: C 25 ppm (125 mg/m3)
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.
May cause gastrointestinal irritation with nausea, vomiting and diarrhea.
May cause irritation of the respiratory tract with burning pain in the nose and throat, coughing, wheezing, shortness of breath and pulmonary edema.
Causes skin irritation.
Causes eye irritation. Vapors may cause eye irritation.
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists. Wash clothing before reuse.
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
