No information available

Warning Properties:
Information not available for evaluation.

Uses and Occurrences:
Solvent


SECTION 3. HAZARDS IDENTIFICATION

EMERGENCY OVERVIEW:
Colourless liquid. FLAMMABLE LIQUID AND VAPOUR. Vapour is heavier than air and may spread long distances. Distant ignition and flashback are possible. 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 exposures, 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 available on diethylene glycol ethyl vinyl ether. Can be absorbed through the skin, but exposure must be severe before health effects would be reported.

Eye Contact:
Liquid is essentially non-irritating. It was rated 1 on a scale of 10 in rabbit eye tests.(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:
Probably 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 condition of use in the particular workplace.



SECTION 5. FIRE FIGHTING MEASURES

Flash Point:
32.8 deg C (91 deg F) (open cup)

Lower Flammable (Explosive) Limit (LFL/LEL):
0.4%

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

Autoignition (Ignition) Temperature:
201 deg C (394 deg F)

Sensitivity to Mechanical Impact:
Not sensitive. Stable material.

Sensitivity to Static Charge:
No information is available on electrical conductivity. However, vapours in the flammable range may be ignited by a static discharge of sufficient energy.

Fire Hazard Summary:
Flammable liquid. Can release vapours that form explosive mixtures with air at, or above, 32 deg C. Vapour is heavier than air and may travel a considerable distance to a source of ignition and flash back to a leak or open container.

Extinguishing Media:
Carbon dioxide, dry chemical powder, alcohol foam. Water may be ineffective, since it may not cool diethylene glycol ethyl vinyl ether below its flash point.

Fire Fighting Instructions:
Diethylene glycol ethyl vinyl ether is soluble in water and has a moderately low flash point. Water may be ineffective for fighting fires involving this compound, unless used under favourable conditions by experienced fire fighters trained in fighting all types of flammable liquid fires. However, water may be used to dilute the liquid to the point where it is no longer flammable.
Also, water can be used in the form of a spray or mist to absorb heat, keep containers cool and protect exposed material. If a spill or leak has not ignited, use water spray to disperse the vapours and to protect personnel attempting to stop a leak. Water spray may be used to flush spills away from ignition sources.
Fire fighters may enter the area if positive pressure self-contained breathing apparatus (MSHA/NIOSH approved or equivalent) and full Bunker Gear is worn.
