Specific Hazards: Vapors may form flammable mixtures with air. Containers may explode when heated.
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, organic vapors
Protective Equipment: Firefighters wear self-contained breathing apparatus and full protective gear.
Personal Precautions: Evacuate area and ventilate. Remove ignition sources. Avoid inhalation and skin contact.
Protective Equipment: Chemical-resistant gloves, safety goggles, protective clothing, and appropriate respiratory protection.
Environmental Precautions: Prevent entry into waterways, drains, or confined areas. Inform relevant authorities if product causes environmental pollution.
Clean-Up Methods: Absorb with inert material (sand, earth). Collect spilled material in separate containers. Dispose of according to local regulations.
Handling: Use in well-ventilated areas. Keep away from sources of ignition, hot surfaces, static discharge, sparks, and open flames. Wear personal protective equipment. Do not breathe vapors or mists. Avoid contact with eyes and skin.
Storage: Store in tightly closed containers in a cool, dry, and well-ventilated place. Store away from oxidizing agents, acids, alkalis, direct sunlight, heat, and ignition sources. Ground and bond containers when transferring liquid.
Exposure Limits: No established OSHA, ACGIH, or NIOSH limits; recommend using general solvent exposure guidelines (50 ppm as TWA for similar glycol ethers)
Engineering Controls: Use local exhaust ventilation or process enclosure to control airborne exposures. Provide eyewash stations and safety showers near workstations.
Personal Protective Equipment:
Respiratory: Use organic vapor respirators if ventilation inadequate
Skin: Wear chemical-resistant gloves and protective clothing
