First Aid Measures

Ingestion
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.
Inhalation
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Skin
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.
Eyes
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.

Handling and Storage

Storage
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.
Handling
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.

Hazards Identification

Inhalation
May cause irritation of the respiratory tract with burning pain in the nose and throat, coughing, wheezing, shortness of breath and pulmonary edema.
Skin
Causes skin irritation.
Eyes
Causes eye irritation. Vapors may cause eye irritation.
Ingestion
May cause gastrointestinal irritation with nausea, vomiting and diarrhea.
EC Risk Phrase
R 36/38

Exposure Controls/Personal Protection

Personal Protection
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.
Respirators
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.
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.
Exposure limit(s)
TLV: 25 ppm; 121 mg/m3 ceiling (ACGIH 1995-1996). NIOSH REL: C 25 ppm (125 mg/m3)
Poison Class
4

Fire Fighting Measures

Flash Point
93
Autoignition
425
Fire Fighting
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.
Upper exp. limit
7.4
Lower exp. limit
1.3
Fire Potential
Slightly flammable. Combustion requires preheating. Moderate hazard.

Accidental Release Measures

Small spills/leaks
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.

Stability and Reactivity

Disposal Code
1
Stability
Stable under normal temperatures and pressures.
Incompatibilities
Strong acids, strong oxidizing agents, acid chlorides, strong reducing agents and acid anhydrides.
Decomposition
Carbon monoxide, irritating and toxic fumes and gases, carbon dioxide, acrid smoke and fumes.
