Swallowed: If a very minor amount has been accidentally swallowed, then if conscious, rinse mouth with
water and then dilute stomach contents by giving large amounts of water. Seek medical
attention.
Do not attempt to induce vomiting or give anything by mouth to an unconscious person. If
person vomits, place person on their side in recovery position.
Eyes: Flush eye with water for a minimum of 15 minutes. Seek medical attention if irritation persists or
any loss of vision occurs.
Skin: Immediately remove all contaminated clothing. Wash affected skin with water. Launder
contaminated clothing before re-use. If irritation persists, seek medical attention.
Inhaled: Remove promptly to fresh air. If there are signs of drunkenness (intoxication or inebriation) or
respiratory irritation, dizziness, nausea or unconsciousness occurs, seek immediate medical
attention. Apply artificial respiration if breathing stops.
First Aid Facilities: Safety showers, eye wash stations and first aid kits.
Advice to Doctor: Treat symptomatically and as for a narcotic substance/alcohol poisoning. Supportive, hospital
or even intensive care may be required.
SECTION 5: FIRE FIGHTING MEASURES
Highly flammable liquid. May form flammable mixtures with air. Burns with a
Flammability:
colourless flame. The vapour is heavier than air and may travel along the
ground; distant ignition and flash back are possible.
Run off to sewers and drains may cause explosions. Isolate for at least 800
metres in all directions if tanks or tankers are involved. The use of compressed
air for filling, discharging, mixing or handling is prohibited due to the vapour
hazard.
All vessels must be earthed to avoid generation of static charges when agitating
or transferring solvents. Avoid all ignition sources. Intrinsically safe equipment
is necessary in areas where this chemical is being used.
Suitable extinguishing media: Use water fog (or if unavailable fine water spray), dry chemical, carbon dioxide
or alcohol stable foam.
Hazards from combustion products: Burning can produce carbon monoxide and/or carbon dioxide.
Special protective precautions and Highly flammable liquid. Use water to cool exposed containers. Heating can
equipment for fire fighters: cause expansion or decomposition leading to violent rupture of containers. If
safe to do so, remove containers from path of fire.
Spills and leaks may be washed away with copious volumes of water, fog or
spray.
For major fires or where the atmosphere is either oxygen deficient or contains
unacceptable levels of combustion products, firefighters must wear self-
contained breathing apparatus with full face-mask and protective clothing.

vapour.
Clear area of all personnel not directly involved in the clean up.
All personnel involved in the containment and disposal procedures to wear
protective equipment as described in Section 8 to prevent skin and eye
contamination and inhalation of vapours.
Ventilate area well and ensure the atmosphere is safe before personnel return
to the work area.
Containment Procedure: Stop and contain the spill for salvage or absorb in inert absorbent material (e.g.
soil, sand, vermiculite) for disposal by an approved method.
Prevent run-off into drains and waterways.
If contamination of sewers or waterways has occurred, advise the local
emergency services.
Clean Up Procedure: Wash the cleaned up area with copious volumes of water to remove any trace
amounts of product.
Non-returnable containers should be de-gassed prior to disposal. Dispose of all
waste containers and used drums in accordance with local authority guidelines.
SECTION 7: HANDLING AND STORAGE
Handling: Use in well ventilated areas away from all ignition sources. Intrinsically safe
equipment only must be used in area where this chemical is being used.
The use of compressed air for filling, discharging, mixing or handling is
prohibited due to the vapour hazard. Containers must be earthed to avoid
generation of static charges when agitating or transferring product.
Storage: Store in tightly closed containers in cool, dry, isolated and well ventilated areas
away from heat, sources of ignition and incompatibles. Store away from
oxidizing agents. Keep containers closed at all times; check regularly for leaks.

SECTION 8: EXPOSURE CONTROLS / PERSONAL PROTECTION
Exposure Standards: National Occupational Exposure Standard (NES) Australian Safety &
Compensation Council, ASCC (formerly NOHSC)
Ethanol:
3
TWA - 1000 ppm (1880 mg/m )
STEL - None Allocated
Carcinogen Category - None Allocated
Notices - None Allocated
MIBK:
3
TWA - 50 ppm (205 mg/m )
STEL - 75 ppm (307 mg/m3)
Carcinogen Category - None Allocated
Notices - None Allocated
Notes: All occupational exposures to atmospheric contaminants should be kept to as
low a level as is workable (practicable) and in all cases to below the National
Standard.
TWA (Time Weighted Average): the time-weighted average airborne
concentration over an eight-hour working day, for a five-day working week over
an entire working life. According to current knowledge this concentration should
neither impair the health of, nor cause undue discomfort to, nearly all workers.
STEL (Short Term Exposure Limit): the average airborne concentration over a
15 minute period which should not be exceeded at any time during a normal
eight-hour work day.
Biological Limit Values: N/A
ENGINEERING CONTROLS
Ventilation: Local exhaust ventilation and/or mechanical (general) exhaust is recommended
where vapours are likely to be generated. All such equipment must be
intrinsically safe. MIBK should be used in minimal quantities in designated
areas with adequate ventilation and away from sources of heat or sparks.
Special Consideration for Empty containers retain residue (liquid and/or vapour) and are dangerous. Do
Repair &/or Maintenance of not pressure cut, weld, braze, solder, drill, grind or expose such containers to
Contaminated Equipment: heat, flame, sparks, static electricity, or other sources of ignition.
Vapour is heavier than air 鈥? prevent concentration in hollows or sumps. Do not
enter confined spaces where vapour may have collected. Keep containers
closed when not in use. Containers should be grounded during transfer or
mixing operations.
PERSONAL PROTECTION
Personal Hygiene Protective clothing (gloves, coveralls, boots, etc.) should be worn to prevent
skin contact. Always wash hands before smoking, eating, drinking or using the
toilet.
Wash contaminated clothing and other protective equipment before storing or
re-using.
Skin Protection: Avoid skin contact by the use of approved chemical resistant gloves and aprons
selected as appropriate to the task, in accordance with AS2161, and with
reference to glove manufacturers recommendations. Chemical resistant barrier
gloves should be used where risk of contact with MIBK is high. PVC, neoprene,
rubber and nitrile gloves are not recommended for use with MIBK.
Eye Protection: Avoid eye contact by wearing chemical goggles with side shields or face shield
(AS/NZS 1336) whenever exposed to vapour or mist or if there is a risk of
splashing liquid in the eyes.
Safety showers with eye-wash should be provided in all areas where product is
handled.
CSR SDS Reference: ETH-SDS-053
Date Issued: March 2008
MSDS for Mixed Denaturant Page 5 of 8
Respiratory Protection: None should be needed if engineering, storage and handling controls are
adequate to ensure that atmospheric contamination is kept below the National
Standard.
Where vapour concentrations are likely to approach or exceed the National
Standard, an approved organic vapour respirator (AS/NZS 1715 and 1716)
must be worn.
In high vapour concentrations at or above the occupational limit, consideration
should be given to wearing powered positive pressure air purifying respirators or
air-supplied hood type.
In suspected oxygen deficient atmospheres, such as empty vessels or confined
spaces, positive pressure full face-piece self-contained breathing apparatus
should be worn.
Smoking: Smoking must be prohibited in all areas where this product is used - see safety
information on flammability.

SECTION 11: TOXICOLOGICAL INFORMATION
Toxicological Data:
Acute toxicity (ethanol): LD50/oral/rat: 7060 mg/kg (literature data)
LC50/inhalation/rat: 38 mg/l/10 h (literature data)
Acute toxicity (MIBK): LD50/oral/rat: 2080 mg/kg
Health effects information is based on reported effects in use from overseas and Australian reports.
ASCC (NOHSC) does not classify ethanol as a carcinogen. IARC has evaluated ethanol IARC has evaluated ethanol
as a carcinogen on the basis of effects of drinking alcoholic beverages, but there is no known carcinogenic risk from
occupational exposures. There is extensive toxicological and epidemiological information on the health effects of
ingesting alcoholic drinks containing ethanol.
Effects: Acute
Swallowed: Accidental swallowing is unlikely under normal occupational exposures.
Swallowing ethanol can cause harmful central nervous system effects. Effects may include
excitation, euphoria, headache, dizziness, drowsiness, blurred vision, fatigue, tremors,
convulsions, loss of consciousness, coma, respiratory arrest and death. Severe acute
intoxication may cause hypoglycaemia, hypothermia and extensor rigidity. Other effects
may include decreased blood pressure, vomiting blood, and blood changes.
Swallowing a minor amount of MIBK may cause throat irritation, vomiting and diarrhoea.
Ingestion of larger amounts may cause narcotic effects, and lead to coma and death.
Swallowing the liquid may cause aspiration into the lungs with the risk of chemical
pneumonitis.
Eyes: Vapours may irritate the eyes resulting in redness, pain and swelling. Liquid and mists may
severely irritate or damage the eyes.
Skin: Contact with skin will result in moderate irritation. Brief contact may cause redness. A
small proportion of people exposed to repeated skin contact may develop an allergic skin
reaction.
Inhaled: Ethanol vapour is moderately irritating to mucous membranes and respiratory tract.
Inhalation of ethanol vapour may result in drunkenness, headache, nausea, incoordination,
narcosis and vomiting. Symptoms may occur at airborne levels of 1000 to 5000 ppm. High
concentrations may cause central nervous symptoms similar to 鈥淪wallowed鈥? above.
Inhalation of MIBK vapour can cause irritation of the nose and throat and upper respiratory
tract. Inhalation of higher concentrations of MIBK can cause drowsiness, headache,
nausea, dizziness and eventually unconsciousness. Harmful if aspirated into the lungs,
may cause chemical pneumonitis.
Effects: Chronic
Nasal and eye irritation may occur at concentrations below the exposure standard.
Long term exposure by swallowing or repeated inhalation may cause degenerative changes in the liver, kidneys,
gastrointestinal tract and heart muscle.
Prolonged or repeated contact and heavy skin contamination may cause skin drying and cracking and/or dermatitis with
redness, itching, and swelling. This may lead to secondary infection.
Exposure to ethanol in the work setting adds to any intake from alcoholic drinks and any health effects caused by the
total intake of alcohol.

Additional Notes
In work areas where exposures in excess of the occupational exposure limits occur, then the following may apply:
Persons with pre-existing liver impairment, skin and respiratory disorders may be at an increased risk.
Absorption of some drugs may be affected causing adverse health effects.
Ethanol may cause adverse reproductive effects. Ingestion by pregnant women may cause serious effects in their
newborn babies (鈥渇oetal alcohol syndrome鈥?).
A blood alcohol level in excess of 0.05g/100ml is regarded as likely to impair functioning for tasks such as operating
machinery.
The denaturant (denatonium benzoate) is a very bitter substance. It never exceeds 1.0% of the final product and at this
low concentration will not affect the safety of the product.
