4. First Aid Measures

Ingestion: If swallowed, do not induce vomiting. Immediately rinse mouth with water. Give 3 to 4 glasses of water. Never give anything by mouth to an unconscious person. Seek immediate medical attention.
Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. Do not use mouth-to-mouth method if victim inhaled the substance. Induce artificial respiration with the aid of a pocket mask equipped with a oneway valve or other proper respiratory medical device. If breathing is difficult, give oxygen. Seek medical attention if breathing problems develop.
Skin Contact: In case of skin contact, immediately remove contaminated clothing and wash affected areas with water and soap. Seek medical attention if symptoms occur.
Eye Contact: In case of eye contact, hold eyelids open and rinse with water for at least 15 minutes. Seek immediate medical attention.
Other Information: No further relevant information available.

5. Firefighting Measures

Suitable extinguishing equipment

Fire: Water fog, foam, dry chemical or carbon dioxide.
HAZCHEM: Not available.

Special protective equipment and precautions for fire fighters

Hazardous combustion products include acrid smoke and fumes. Product is highly flammable. Vapours may travel considerable distances to a source of ignition where they can ignite, flashback, or explode. Closed containers may explode when exposed to extreme heat. Containers close to fire should be removed if safe to do so. Use water spray to cool fire exposed containers.
Acrid smoke and fumes. When fighting a major fire wear self-contained breathing apparatus and protective equipment.

6. Accidental Release Measures

Personal precautions, protective equipment and emergency procedures: Wear appropriate respiratory protection and protective clothing. Evacuate all non-essential personnel from affected area. Do not breathe vapours. Ensure adequate ventilation. Extinguish all sources of ignition. Avoid sparks and open flames. No smoking.
Environmental precautions: In the event of a major spill, prevent spillage from entering drains or water courses.
Methods and materials for containment and clean up: Stop leak if safe to do so and absorb spill with sand, earth, vermiculite or some other absorbent material. Collect the spilled material and place into a suitable container for disposal. Use non-sparking tools. For large spills, contact emergency services. Bund the area and blanket the spill with foam or use water fog to disperse vapours.

7. Handling and Storage

Precautions for safe handling: Use of safe work practices are recommended to avoid eye or skin contact and inhalation of vapours. Food, beverages and tobacco products should not be stored or consumed where this material is in use. Always wash hands before smoking, eating, drinking or using the toilet. Wash contaminated clothing and other protective equipment before storage or re-use. Provide eyewash fountains and safety showers in close proximity to points of potential exposure.
Conditions for safe storage: Store in a cool, dry and well ventilated area. Keep in original container tightly closed when not in use. Protect from direct sunlight, heat, sparks, open flames and other sources of ignition. Keep away from strong oxidising agents, nitrates, acids and alkalies.

8. Exposure Controls / Personal Protection

Exposure Standards

Material	TWA ppm	TWA mg/m³	STEL ppm	STEL mg/m³
Ethanol	1000ppm	1880 mg/m³	-	-
Methanol	200 ppm	262 mg/m³	250 ppm	328 mg/m³
Acetic acid	10 ppm	25 mg/m³	15 ppm	37 mg/m³

Engineering controls: Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapour below occupational exposure standards.
Prevent accumulation of gases in hollows or sumps. Do not enter room unless monitored by another person (i.e. buddy-buddy system.

Personal protective equipment

Eye and face protection: Eye and face protectors for protection against splashing materials or liquids. See Australian/New Zealand Standard AS/NZS 1337 for more information.
Skin protection: PVC or rubber gloves. See Australian/New Zealand Standard AS/NZS 2161 for more information. When selecting gloves for use against certain chemicals, the degradation resistance, permeation rate and permeation breakthrough time should be considered. Occupational protective clothing (depending on conditions in which it has to be used, in particular as regards the period for which it is worn, which shall be determined on the basis of the seriousness of the risk, the frequency of exposure to the risk, the characteristics of the workstation of each worker and the performance of the protective clothing). See Australian/New Zealand Standard AS/NZS 4501 for more information.
Body protection: No information available.
Respiratory protection: When vapours approach the exposure standards then the use of a half-face organic vapour respirator with dust/mist filter is recommended. When vapours exceed the exposure standards, the use of an positive pressure demand self-contained orairline breathing apparatus is recommended. Filter capacity and respirator type depends on exposure levels. If entering spaces where the airborne concentration of a contaminant is unknown then the use of a selfcontained breathing apparatus (SCBA) with positive pressure air supply is recommended. See Australian Standards AS/NZS 1715 and 1716 for more information.

11. Toxicological Information

Acute effects: Methanol has been reported to cause death or serious irreversible injury such as blindness in humans. Studies in experimental animals indicate that the metabolism of methanol to formic acid results in metabolic acidosis and reversible or irreversible damage to the optic nerve. Ingestion of methanol, even in small amounts, can cause blindness and death. Onset of symptoms may be delayed for 18 - 24 hours and are similar in affect to ethanol poisoning.
Eye contact: May cause eye irritation, stinging, tearing and blurred vision.
Skin contact: Toxic in contact with skin. Causes skin irritation, itchiness, redness, drying and defatting.
Ingestion: Toxic if swallowed. May cause irritation of mouth, throat and stomach, mucous build up, stomach pain, nausea, vomiting and diarrhoea. Overexposure to methanol can cause death or damage to kidneys, liver, lungs, eyes, brain and nervous system.
