Section 3 - Hazards Identification


Appearance: almost colorless liquid.
Caution! May cause eye, skin, and respiratory tract irritation.
Target Organs: No data found.

Potential Health Effects 
Eye: May cause mild eye irritation.
Skin: May cause mild skin irritation. May be absorbed through the skin.
Ingestion: May cause digestive tract disturbances.
Inhalation: May cause respiratory tract irritation.
Chronic: No information found.

Section 4 - First Aid Measures

Eyes: In case of contact, immediately flush eyes with plenty of water for a t least 15 minutes. Get medical aid.
Skin: In case of contact, flush skin with plenty of water. Remove contaminated clothing and shoes. Get medical aid if irritation develops and persists. Wash clothing before reuse.
Ingestion: If swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. Get medical aid.
Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician: Treat symptomatically and supportively.

Section 5 - Fire Fighting Measures

General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Containers may explode when heated. This liquid floats on water and may travel to a source of ignition and spread fire.
Extinguishing Media: In case of fire, use water, dry chemical, chemical foam, or alcohol-resistant foam.
Flash Point: 101 deg C ( 213.80 deg F)
Autoignition Temperature: 310 deg C ( 590.00 deg F)
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating: (estimated) Health: 1; Flammability: 1; Instability: 0

Section 6 - Accidental Release Measures

General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Clean up spills immediately, observing precautions in the Protective Equipment section. Provide ventilation.

Section 7 - Handling and Storage

Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Avoid breathing vapor or mist.
Storage: Keep container closed when not in use. Store in a cool, dry, well-ventilated area away from incompatible substances. Store at 15°-25°C.

Section 8 - Exposure Controls, Personal Protection

Engineering Controls: Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate ventilation to keep airborne concentrations low.

Section 11 - Toxicological Information

CAS# 112-73-2: KN0350000
CAS# 112-73-2:
     Oral, rat: LD50 = 3900 mg/kg;
     Skin, rabbit: LD50 = 4040 uL/kg;
Skin, rabbit: LD50 = 4040 uL/kg = 3555 mg/kg.
CAS# 112-73-2: Not listed by ACGIH, IARC, NTP, or CA Prop 65.

Epidemiology: No information found.
Teratogenicity: No information found.
Reproductive Effects: As is the case for some other glycol ethers, diglyme produces testicular toxicity in rats, producing degeneration of spermatocytes. This effect, which is mediated by the methoxyacetic acid metabolite, appears to be reversible.
Mutagenicity: No information found.
Neurotoxicity: No information found.
