SECTION 2. DESCRIPTION

Appearance and Odour:
Colourless liquid

Odour Threshold:
No information available

Warning Properties:
Information not available for evaluation.

Uses and Occurrences:
Chemical intermediate; cross-linking agent


SECTION 3. HAZARDS IDENTIFICATION

EMERGENCY OVERVIEW:
Colourless liquid. Can probably burn if strongly heated. Very mild central nervous system depressant. May cause headache, nausea, dizziness, drowsiness and incoordination.



POTENTIAL HEALTH EFFECTS

Effects of Short-Term (Acute) Exposure

Inhalation:
No adverse effects on humans have been reported. This material does not tend to form vapours at normal room temperatures and appears to have a low acute toxicity in animal tests. Therefore, no short-term health effects are expected unless the material is heated or mists are formed. In severe cases, effects might be like those described for ingestion, below.

Skin Contact:
Does not cause irritation and has not been reported to cause sensitization. Although allergic reactions to glycols are rare, contact sensitivity to some glycols has been reported. There is no information on diethylene glycol divinyl ether in this regard. Can be absorbed through the skin, but exposure must be severe before health effects would be reported.

Eye Contact:
Liquid is essentially non-irritating.(1)

Ingestion:
No cases have been reported, but early symptoms are expected to be similar to those of alcohol intoxication. Vomiting, bluish colouring of the skin (cyanosis), headache, rapid respiration and heart rate, low blood pressure, muscle tenderness, and unconsciousness may follow. Large or repeated amounts may affect kidney function.

Effects of Long-Term (Chronic) Exposure

No adverse human experience has been reported.

SKIN: Can be absorbed through the skin in toxic amounts if contact is extensive and prolonged.

Carcinogenicity:

No human or animal information is available.

The International Agency for Research on Cancer (IARC) has not evaluated the carcinogenicity of this chemical.

The American Conference of Governmental Industrial Hygienists (ACGIH) has no listing for this chemical.

The US National Toxicology Program (NTP) has not listed this chemical in its report on carcinogens.

Teratogenicity and Embryotoxicity:
The available evidence suggests that most diethylene glycol ethers do not cause reproductive effects. There is some evidence that the monomethyl ether causes reproductive effects in animals. (See CHEMINFO record no. 50E for details).

Reproductive Toxicity:
No human or animal information is available.

Mutagenicity:
No information is available.

Toxicologically Synergistic Materials:
No information is available.

Potential for Accumulation:
None. Ethers of diethylene glycol do not appear to be metabolized to oxalic acid.


SECTION 4. FIRST AID MEASURES

Inhalation:
If symptoms occur, remove source of contamination or move victim to fresh air. Obtain medical advice immediately.

Skin Contact:
Flush contaminated area with lukewarm, gently running water for at least 5 minutes, or until the chemical is removed. Obtain medical advice immediately. Completely decontaminate clothing, shoes and leather goods before re-use or discard.

Eye Contact:
If irritation occurs, immediately flush the contaminated eye(s) with lukewarm, gently flowing water for at least 5 minutes, or until the chemical is removed, while holding the eyelid(s) open. If irritation persists, obtain medical attention immediately.

Ingestion:
Never give anything by mouth if victim is rapidly losing consciousness, is unconscious or convulsing. Have victim rinse mouth thoroughly with water. DO NOT INDUCE VOMITING. Have victim drink 240 to 300 ml (8 to 10 oz.) of water to dilute material in stomach. Obtain medical attention immediately.

First Aid Comments:
Provide general supportive measures (comfort, warmth, rest). Consult a doctor and/or the nearest Poison Control Centre for all exposures except minor instances of inhalation or skin contact. All first aid procedures should be periodically reviewed by a doctor familiar with the material and its conditions of use in the particular workplace.



SECTION 5. FIRE FIGHTING MEASURES

Flash Point:
Not available

Lower Flammable (Explosive) Limit (LFL/LEL):
Not available

Upper Flammable (Explosive) Limit (UFL/UEL):
Not available

Autoignition (Ignition) Temperature:
Not available

Sensitivity to Mechanical Impact:
Not sensitive. Stable material.

Sensitivity to Static Charge:
No information available.

Fire Hazard Summary:
This material can probably burn if strongly heated.

Extinguishing Media:
No specific information available. In common with other diethylene glycol ethers, alcohol foam, dry chemical powder, carbon dioxide, water spray or fog may be effective.

Fire Fighting Instructions:
Water spray, fog or alcohol foam can probably be used to extinguish fires involving diethylene glycol divinyl ether.
Water spray can be used to absorb heat, keep containers cool and protect exposed material. If a leak or spill has not ignited, use water spray to disperse the vapours and to protect personnel attempting to stop a leak. Water spray can be used to flush spills away from ignition sources.
Firefighters may enter the area if positive pressure self-contained breathing apparatus (MSHA/NIOSH approved or equivalent) and full Bunker Gear is worn.
