4. Description of First Aid Measures


For advice, contact a Poisons Information Centre (e.g. phone Australia 131 126; New Zealand 0800  764 766) or a doctor.  

Inhalation: Remove victim from area of exposure – avoid becoming a casualty. Remove  contaminated clothing and loosen remaining clothing. Allow patient to assume most comfortable  position and keep warm. Keep at rest until fully recovered. If patient finds breathing difficult and  develops a bluish discolouration of the skin (which suggests a lack of oxygen in the blood – cyanosis),  ensure airways are clear of any obstruction and have a qualified person give oxygen through a face  mask. Apply artificial respiration if patient is not breathing. Seek immediate medical advice.  

Skin Contact: If skin contact occurs, remove contaminated clothing and wash skin with running  water. If irritation occurs seek medical advice.  

Eye Contact: If in eyes, wash out immediately with water. In all cases of eye contamination it is a  sensible precaution to seek medical advice.  

Ingestion: Rinse mouth with water. If swallowed, give a glass of water to drink. If vomiting occurs give  further water. Seek immediate medical assistance.  

Indication of immediate medical attention and special treatment needed: Treat symptomatically.  Following ingestion admission to hospital should be the first priority. Gastric lavage or emesis should  be performed as soon as possible to minimise absorption and is recommended within four hours of  ingestion. Gastric lavage or emesis should not be attempted unless medical expertise or adequate  facilities are available. Ethanol may be given intravenously as an antidote to prevent build-up of toxic  metabolites and increase excretion of unchanged ethylene glycol by the kidneys. Uraemia, pulmonary  oedema and metabolic acidosis can occur and dialysis, preferably haemodialysis, may be employed  to treat these complications and to remove ethylene glycol and its metabolites from the blood.  Ethylene glycol can cause central nervous system depression and metabolic acidosis. Consider  removal by gastric lavage. Blockade of the diacid/hydroxyacid metabolites may follow competitive  inhibition of alcohol dehydrogenase with ethanol or 4-methyl pyrazole. Consider maintenance of a  plasma ethanol level of 100 mg/dL to 150 mg/dL.  

5. Fire Fighting Measures


Suitable Extinguishing Media:  

Fine water spray, normal foam, dry agent (carbon dioxide, dry chemical powder).

lead to the containers exploding. If safe to do so, remove containers from the path of fire. Keep  containers cool with water spray.  

6. Accidental Release Measures


Emergency procedures/Environmental precautions:  

Clear area of all unprotected personnel. Shut off all possible sources of ignition. If contamination of  sewers or waterways has occurred advise local emergency services.  

Personal precautions/Protective equipment/Methods and materials for containment and  cleaning up:  

Slippery when spilt. Avoid accidents, clean up immediately. Wear protective equipment to prevent skin  and eye contact and breathing in vapours. Work up wind or increase ventilation. Contain – prevent run  off into drains and waterways. Use absorbent (soil, sand or other inert material). Collect and seal in  properly labelled containers or drums for disposal. Wash area down with excess water.  

7. Mono Ethylene Glycol (MEG) – Handling and Storage


Classified as a C1 (COMBUSTIBLE LIQUID) for the purpose of storage and handling, in accordance  with the requirements of AS 1940. Refer to State Regulations for storage and transport requirements.  

This material is a Scheduled Poison S6 and must be stored, maintained and used in accordance with  the relevant regulations.  

Precautions for safe handling:  

Avoid skin and eye contact and breathing in vapour. Keep out of reach of children.  

Conditions for safe storage, including any incompatibilities:  

Store in a cool, dry, well ventilated place and out of direct sunlight. Store away from foodstuffs. Store  away from incompatible materials described in Section 10. Keep containers closed when not in use –  check regularly for leaks.  

8. Exposure Controls/Personal Protection


Ethylene glycol (vapour): 8hr TWA = 52 mg/m3 (20 ppm), 15 min STEL = 104 mg/m3 (40 ppm), Sk  Ethylene glycol (particulate): 8hr TWA = 10 mg/m3 , Sk  

As published by Safe Work Australia Workplace Exposure Standards for Airborne Contaminants.  

TWA – The time-weighted average airborne concentration of a particular substance when calculated  over an eight-hour working day, for a five-day working week.  

STEL (Short Term Exposure Limit) – the airborne concentration of a particular substance calculated as  a time-weighted average over 15 minutes, which should not be exceeded at any time during a normal  eight hour work day. According to current knowledge this concentration should neither impair the  health of, nor cause undue discomfort to, nearly all workers.  

`Sk’ (skin) Notice – absorption through the skin may be a significant source of exposure. The exposure  standard is invalidated if such contact should occur.  

These Workplace Exposure Standards are guides to be used in the control of occupational health  hazards. All atmospheric contamination should be kept to as low a level as is workable.  These workplace exposure standards should not be used as fine dividing lines between safe and  dangerous concentrations of chemicals. They are not a measure of relative toxicity.

Appropriate engineering controls:  

Ensure ventilation is adequate and that air concentrations of components are controlled below quoted  Workplace Exposure Standards. Vapour heavier than air – prevent concentration in hollows or sumps.  DO NOT enter confined spaces where vapour may have collected. Keep containers closed when not  in use.  

If in the handling and application of this material, safe exposure levels could be exceeded, the use of  engineering controls such as local exhaust ventilation must be considered and the results  documented. If achieving safe exposure levels does not require engineering controls, then a detailed  and documented risk assessment using the relevant Personal Protective Equipment (PPE) (refer to  PPE section below) as a basis must be carried out to determine the minimum PPE requirements.  

Individual protection measures, such as Personal Protective Equipment (PPE):  The selection of PPE is dependent on a detailed risk assessment. The risk assessment should  consider the work situation, the physical form of the chemical, the handling methods, and  environmental factors.  


Wear overalls, safety glasses and impervious gloves. Use with adequate ventilation. If determined by  a risk assessment an inhalation risk exists, wear an organic vapour respirator meeting the  requirements of AS/NZS 1715 and AS/NZS 1716. Always wash hands before smoking, eating,  drinking or using the toilet. Wash contaminated clothing and other protective equipment before  storage or re-use.

11. Mono Ethylene Glycol (MEG) – Toxicological Information


No adverse health effects expected if the product is handled in accordance with this Safety Data  Sheet and the product label. Symptoms or effects that may arise if the product is mishandled and  overexposure occurs are:  


Initial symptoms following a large dose (>100ml) are those of alcohol intoxication progressing to  vomiting, headache, stupor, convulsions and unconsciousness. Respiratory system involvement may  occur 12 – 24 hours after ingestion. Symptoms may include hyperventilation and rapid shallow  breathing. Death may occur from respiratory failure or pulmonary oedema.  

Eye contact:  

May be an eye irritant.  

Skin contact: 

Contact with skin may result in irritation. Will have a degreasing action on the skin. Repeated or  prolonged skin contact may lead to irritant contact dermatitis. Can be absorbed through the skin.  Effects can include those described for ‘INGESTION’.  


Breathing in vapour can result in headaches, dizziness, drowsiness, and possible nausea.  

Acute toxicity:  

Oral LD50 (rat): 4700 mg/kg  

Skin corrosion/irritation: Mild irritant (rabbit).  

Serious eye damage/irritation: Mild irritant (rabbit).  

Chronic effects: Available evidence from animal studies indicate that repeated or prolonged  exposure to this material could result in effects on the central nervous system, liver and kidneys .  

Estimated minimum lethal dose (human) following ingestion of ethylene glycol is thought to be  1.4ml/kg. High doses of ethylene glycol in rats and mice have resulted in reproductive and  developmental toxicity following exposure by the oral and inhalation (respirable aerosol) routes. These  particular data sets are not considered relevant to normal industrial use but do emphasise the need  for care in handling.  

Data from animal and human studies to date do not provide evidence that exposure to ethylene glycol  has mutagenic or carcinogenic effects.
