Main Component: Propylene Glycol Methyl Ether
CAS Number: 107-98-2
Percent Range: 99% or greater
Impurities: Typical trace impurities do not significantly alter hazards.
Additives: None common for commercial grade.
Inhalation: Remove to fresh air. Seek medical attention if symptoms develop or persist, including headache, dizziness, or irritation.
Skin Contact: Wash with soap and water. Remove contaminated clothing and launder before reuse. If irritation occurs, get medical attention.
Eye Contact: Flush eyes with plenty of running water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing and seek medical advice if irritation persists.
Ingestion: Rinse mouth with water. Do not induce vomiting unless directed by medical personnel. Get medical help if large amounts are swallowed or symptoms occur.
Note to Physician: Symptomatic and supportive treatment recommended.
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical powder, carbon dioxide, water spray for large fires.
Specific Hazards: Vapors may form explosive mixtures with air. Burning releases toxic gases including carbon monoxide and carbon dioxide.
Protective Equipment and Precautions: Firefighters should wear self-contained breathing apparatus and protective clothing to prevent skin and eye contact.
Firefighting Procedures: Use water spray to cool containers. Avoid direct streams which may spread the fire.
Unusual Fire Hazards: Containers exposed to heat may burst or explode.
Personal Precautions: Evacuate area. Eliminate all sources of ignition. Ventilate the area.
Protective Equipment: Wear gloves, chemical safety goggles, and appropriate protective clothing.
Containment: Prevent entry into drains, surface water, or soil.
Cleanup Methods: Absorb with inert material such as sand or earth. Collect in suitable containers for proper disposal.
Environmental Precautions: Notify authorities if large spills contaminate water or if local regulations require.
Safe Handling: Use with adequate ventilation. Avoid breathing vapors, mist, or spray. Avoid skin and eye contact. Keep away from heat, sparks, and open flames.
Storage Conditions: Store in tightly closed, properly labeled containers in a cool, dry, well-ventilated area away from incompatible materials such as strong oxidizers.
Incompatibilities: Strong acids, base, and oxidizers.
Other Recommendations: Use non-sparking tools and intrinsically safe equipment. Ground and bond containers during transfer.
Occupational Exposure Limits: ACGIH TLV - 50 ppm TWA (184 mg/m³); STEL 100 ppm
Engineering Controls: Local exhaust ventilation or general ventilation to keep vapor concentrations below exposure limits.
Personal Protective Equipment: Eyes: Chemical goggles; Skin: Nitrile or neoprene gloves, protective clothing; Respiratory: Respirator if concentrations exceed limits or during cleanup and maintenance.
Hygiene Measures: Wash hands before breaks and after handling. Remove contaminated clothing and wash before reuse.
