| | Specific Hazards: N/A | ||||
| | | | |||
| Inhalation: | May cause irritation of respiratory tract. May cause central nervous system depression with symptoms of dizziness, headache, nausea, vomiting, drowsiness, and dizziness, and coma. May cause pulmonary edema. Can produce rapid, involuntary eye movement. | ||||
| Skin Contact: | May cause irritation. | ||||
| Skin Absorption: | May be absorbed through the skin in harmful amounts. | ||||
| Eye Contact: | May cause irritation, pain, and damage to the eye. | ||||
| Ingestion: | May cause central nervous system depression with symptoms of dizziness, headache, nausea, and drowsiness. High levels of exposure may result in rapid respiratory and heart rate, lowered blood pressure, stupor, collapse, unconsciousness, convulsions, and death due to respiratory failure or cardiovascular collapse. Lethal dose in humans is estimated at 100 ml (3-4 ounces). | ||||
| Effects of Chronic Exposure: Repeated exposures may result in severe kidney damage, liver damage, and brain damage. An allergic skin reaction can develop which becomes evident upon repeated exposure to mono ethylene glycol. Animal studies have reported fetotoxicity and teratogenicity. | |||||
| 8.4: FIRST AID MEASURES |
| Eye Contact: | Immediately flush eyes with water for at least 15 minutes. Hold eyes open while flushing out with water. Seek medical attention immediately. |
| Skin Contact: | Immediately remove contaminated clothing and shoes. Flush skin with water for at least 15 minutes. Use soap if available or follow by washing with soap and water. Do not reuse contaminated clothing without laundering. If irritation persists, seek medical attention. |
| Inhalation: | Remove victim to fresh air. If breathing is difficult, give oxygen. If not breathing, administer artificial respiration. Seek medical attention immediately. |
| Ingestion: | Induce vomiting immediately as directed by medical personnel. Seek medical attention immediately. |
| 8.5: FIREFIGHTING MEASURES |
| Flash Point Temperature: | 232oF, 111oC (CC) |
| Auto ignition Temperature: | 748oF, 398oC |
| Flammable Limits: | Lower: 3.2% Upper: 15.3% |
| Extinguishing Media: | Water, Dry Chemical, “Alcohol” Foam, Carbon Dioxide |
| Firefighting Procedures: | Firefighters should wear NIOSH approved self-contained breathing apparatus and appropriate protective clothing to prevent contact. Cool exposed containers with water. |
| Unusual Fire and Explosion Information: | Do not use direct stream of water to fight fire. Containers can build up pressure if subjected to heat of the fire and may explode. Flashback hazard – vapors are heavier than air and can collect in low areas forming an explosive MEG and air mixture. |
| Environmental Note: | Prevent product from getting into sewers or surface waters. |
| 8.6:ACCIDENTAL RELEASE MEASURES |
Isolate the hazard area and deny entry to nonessential personnel. Emergency responders and/or clean-up personnel should wear appropriate protective clothing and equipment when responding. Remove all ignition sources. Prevent from entering sewers or surface waters. Collect liquid in containers and seal shut. Absorb remaining material with a noncombustible absorbent such as earth, sand, or vermiculite and collect for disposal.
| 8.7: HANDLING AND STORAGE |
Keep away from heat, sparks, and open flames. Keep containers tightly closed. Store away from incompatible materials in a cool, dry place. Use adequate explosion-proof ventilation to prevent accumulation of static charge. When pouring or transferring materials, containers must be bonded and grounded.
Do not weld, heat, or drill on or near full or empty containers. Empty containers can contain explosive vapors.
Do not breathe vapors or mist. Minimize skin contact. Wash with soap and water before eating, drinking, smoking, or using toilet facilities. Launder contaminated clothing before reuse. Properly dispose of contaminated leather articles, including shoes that cannot be decontaminated.
| 8.8: EXPOSURE CONTROLS AND PERSONAL PROTECTION |
| Respiratory Protection: | Utilize NIOSH approved half face or full face respirator with organic vapor/P95 cartridges, supplied air, or self-contained breathing apparatus. Consult with an Industrial Hygienist before determining which respirators to use. Respirators must be utilized in compliance with OSHA regulations 29CFR1910.134. |
| Ventilation: | Use explosion-proof ventilation equipment. Utilize local exhaust to control vapors. Do not rely on general exhaust. |
| Protective Gloves: | Neoprene, nitrile, butyl, PVC, or viton gloves are recommended. |
| Eye Protection: | Chemical goggles and face shield. |
| Other Protective Equipment: | Wear additional protective clothing as required to prevent skin contact. This may include chemical aprons, chemical resistant boots, and chemical resistant suits. Safety shower and eyewash are necessary in work area. |
| Work Practices: | Use good personal hygiene practices. Wash hands before eating, drinking, smoking, or using toilet facilities. Promptly remove contaminated clothing and launder before reuse. Shower after work using plenty of soap and water. |
| Electrical Equipment: | N/A. |
