Fire-Fighting Measures

Suitable Extinguishing Media: Use alcohol-resistant foam, dry chemical or carbon dioxide. Water may not be effective but can cool exposed containers.
Unsuitable Extinguishing Media: Direct high-powered water streams may spread liquid.
Fire Hazards: Product is combustible. Vapors may travel and ignite at a distance.
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, formaldehyde, smoke
Protective Equipment: Firefighters should wear full protective gear and self-contained breathing apparatus.
Special Precautions: Evacuate area. Prevent runoff from enter drains or water courses.

Accidental Release Measures

Personal Precautions: Eliminate sources of ignition. Ventilate area. Use personal protective equipment, including gloves and goggles.
Environmental Precautions: Prevent further leakage or spillage if safe. Do not let product enter drains, waterways, or soil.
Methods for Clean-up: Absorb with earth, sand, or inert material. Collect and place in suitable, properly labeled containers for disposal.
Decontamination: Wash spill site after material pick up is complete.
Other Information: Clean up promptly to avoid slip hazard. Notify authorities in case of large spills or contamination of water bodies.

Handling and Storage

Handling: Do not breathe vapors. Avoid contact with eyes, skin, and clothing. Use only in well-ventilated environments. Wash thoroughly after handling. Remove contaminated clothing and wash before reuse.
Storage: Store in original, tightly-closed containers. Keep away from heat, sparks, open flames, or other ignition sources. Protect against physical damage and direct sunlight. Segregate from incompatible materials such as strong oxidizers and acids.
Storage Temperature: Keep away from excessive heat or freezing conditions (recommended 15–30 °C).
Packaging Materials: Use containers made from compatible materials like stainless steel or certain high-density plastics.

Exposure Controls and Personal Protection

Exposure Limits: No established national exposure limits for dimethoxy dipropyleneglycol, but keep below recommended threshold for general glycol ethers.
Engineering Controls: Local exhaust or general room ventilation is recommended to maintain vapor concentrations below permissible limits.
Personal Protective Equipment: Safety goggles or face shield, chemical-resistant gloves (nitrile or neoprene), protective clothing that prevents skin exposure.
Respiratory Protection: Use an approved respirator if vapor levels exceed applicable limits or in poorly ventilated areas.
Hygiene Measures: Do not eat, drink, or smoke while using this product. Wash hands and exposed areas thoroughly after handling.
Environmental Controls: Avoid environmental exposure. Comply with applicable regulations on emissions.
