Chemical Name: Diethylene Glycol Dimethyl Ether (Diglyme)
Concentration: 99% or greater
CAS Number: 111-96-6
Impurities: May contain trace amounts of diethylene glycol compounds
Other Ingredients: None reported in standard formulations
General Actions: Remove exposed person from source and to fresh air. Seek medical attention immediately for significant symptoms.
Inhalation: Move to fresh air. Give oxygen if breathing is difficult. Contact a doctor.
Skin Contact: Remove contaminated clothing. Wash skin thoroughly with soap and water.
Eye Contact: Flush eyes with water for at least 15 minutes, lifting eyelids periodically. Get medical help.
Ingestion: Rinse mouth with water, do not induce vomiting. Contact a poison center or doctor.
Extinguishing Media: Use alcohol-resistant foam, dry chemical powder, or carbon dioxide. Water spray may be used to cool containers.
Fire Hazards: Vapors form explosive mixtures with air and can travel to ignition sources. Thermal decomposition can produce toxic gases such as carbon monoxide and formaldehyde.
Protective Gear: Firefighters wear self-contained breathing apparatus and full protective clothing.
Special Procedures: Remove containers from fire area if it can be done safely. Use water spray to cool fire-exposed surfaces and prevent rupture.
Personal Precautions: Evacuate area and ensure proper ventilation. Avoid inhalation of vapors. Wear protective equipment including gloves, goggles, and chemical-resistant clothing.
Environmental Precautions: Prevent from entering drains, surface water, or soil.
Clean-Up Method: Use inert absorbent material to contain spill. Collect in containers for disposal according to local regulations. Wash spill area thoroughly with water after clean-up.
Handling: Work in a well-ventilated area or with local exhaust. Avoid breathing vapors or contact with skin and eyes. Use spark-proof tools and keep away from ignition sources. Avoid static discharge during transfer.
Storage: Store in tightly closed containers in a cool, dry, well-ventilated place away from direct sunlight, acids, oxidizers, and heat. Keep away from food and incompatible materials.
Exposure Limits: No specific OSHA PEL or ACGIH TLV, but use with caution and minimize exposure.
Engineering Controls: Use chemical fume hood or local exhaust ventilation.
Personal Protection: Wear chemical-resistant gloves (such as nitrile), splash goggles, lab coat or protective suit, and, for high concentrations, respiratory protection with organic vapor cartridges.
Hygiene Measures: Do not eat, drink, or smoke in work area. Wash hands and face after handling. Remove contaminated clothing before entering eating or restroom areas.
