Chemical Name: Propylene Glycol Beta-Monoethyl Ether
CAS Number: 1569-02-4
Concentration: ≥ 99% by weight
Impurities: Trace levels of other glycol ethers, unreacted starting materials, water (up to 1%)
Inhalation: Move person to fresh air. Seek medical attention if symptoms develop such as dizziness, headaches, or lack of coordination.
Skin Contact: Remove contaminated clothing and wash skin with water and soap. Call a doctor if irritation persists.
Eye Contact: Rinse with water for several minutes, lifting upper and lower eyelids. Remove contact lenses if present and continue rinsing. Obtain medical attention if redness or pain continues.
Ingestion: Rinse mouth with water. Do not induce vomiting unless directed by medical personnel. Call doctor or poison control center immediately for further treatment directions.
Suitable Extinguishing Media: Water spray, foam, carbon dioxide, or dry chemical
Unsuitable Media: Straight water streams may spread burning liquid.
Specific Hazards: Vapor may travel to ignition source. Produces harmful fumes under fire such as carbon monoxide and carbon dioxide.
Protective Equipment: Firefighters need full protective clothing and self-contained breathing apparatus.
Special Procedures: Cool containers with water spray to prevent pressure buildup. Move containers from fire area if safe.
Personal Precautions: Evacuate unnecessary personnel. Ventilate area to prevent vapor accumulation. Avoid inhalation or skin contact. Wear appropriate personal protective equipment (gloves, goggles, respiratory protection).
Environmental Precautions: Prevent product from entering drains, waterways, soil.
Containment: Stop leak if safe. Dike and absorb spillage with inert material such as sand or earth.
Cleanup Methods: Shovel absorbed material into suitable containers for disposal. Wash area with water after cleanup.
Handling: Use in well-ventilated areas. Keep away from heat sources, sparks, open flames. Avoid contact with eyes, skin, clothing. No eating, drinking, or smoking during use.
Storage: Keep in tightly closed original container in cool, dry, well-ventilated storage area. Store away from direct sunlight and incompatible materials such as acids, oxidizers. Ground and bond containers and receiving equipment.
Exposure Limits: Workplace limits for glycol ethers often set at 25 ppm TWA (consult local regulations).
Engineering Controls: Use local exhaust or general ventilation to keep air concentrations below exposure limits.
Personal Protection: Chemical resistant gloves (nitrile, neoprene), splash proof goggles or face shield, flame resistant clothing, and suitable respiratory protection if airborne concentrations exceed exposure limits.
Hygiene Measures: Wash hands before eating, drinking, or using the restroom. Remove contaminated clothing and wash before reuse.
