3. HAZARDS IDENTIFICATION
Highly flammable. Irritating to eyes, respiratory system and skin. May cause sensitisation by skin contact.
4. FIRST AID MEASURES
GENERAL INFORMATION: Remove contaminated or saturated clothing immediately.
INHALATION: Possible discomfort. Irritation of mucous lining (nose, throat, eyes) cough, sneezing, flow of tears.
Take affected persons out into fresh air. In case of persistent discomfort seek medical attention.
SKIN: When contact with skin, flush affected areas with ethanol polyethylene glycol 300 mixture (1:2) and
rinse thoroughly with soap and water.
EYE: Irrigate with eyewash solution or clear water, holding the eyelids apart, for at least 5 minutes. Obtain
immediate medical attention.
INGESTION: Do not induce vomiting. Wash out mouth with water and give 200-300 ml (half a pint) of water to drink.
Obtain medical attention. Never give anything by mouth to an unconscious person. Call a physician.
INSTRUCTIONS FOR DOCTOR At onset of cyanosis (lips, ear lobes, finger nails) give oxygen as quickly as possible
5. FIRE FIGHTING MEASURES
EXTINGUISHING MEDIA: Dry Sand, foam, dry powder or CO2. Keep fire exposed containers cool by spraying with water.
UNSUITABLE MEDIA: Full water jet
PARTICULAR DANGER CAUSED BY MATERIAL, ITS COMBUSTION PRODUCTS OR GASES PRODUCED:
Formation of flammable or explosive vapour/air mixtures possible. In the case of fire Methyl Methacrylate may be
released.
FIRE FIGHTING PROTECTIVE EQUIPMENT: A self-contained breathing apparatus and suitable protective clothing
should be worn in fire conditions.
ADDITONAL INFORMATION: Product is highly flammable.
Keep away from sources of ignition. Do not smoke. Caution electrostatic charge may occur.
6. ACCIDENTAL RELEASE MEASURES
Ref. C:\MSDS\CONDOLIQ.DOC Prepared May 2005
Page 2 of 7
MATERIAL SAFETY DATA SHEET
Eliminate sources of ignition. Ensure suitable personal protection (including respiratory protection) during removal of
spillages. Prevent entry into drains. Adsorb spillages onto sand, earth or any suitable adsorbent material. Do not
adsorb onto sawdust or other combustible materials. Transfer to a container for disposal or recovery.
7. HANDLING AND STORAGE
HANDLING: Avoid contact with skin and eyes.
Avoid inhalation of high concentration of vapors. Use only in well ventilated areas.
The vapour is heavier than air; beware of pits and confined spaces. Take precautionary measures
against static discharges.
STORAGE: Keep only in original container. Store in cool dry place away from heat, sparks, flame and direct
sunlight.
Keep container closed to prevent water absorption and contamination. Keep away from sources of
ignition 鈥? No Smoking. Ensure there is good room ventilation.
STORAGE TEMPERATURE: Preferably not exceeding 25 潞C.
INDUSTRIAL HYGIENE PRACTICES: Wash face and hands thoroughly with the soap and water after use and before
eating, drinking, smoking or applying cosmetics.
8. EXPOSURE CONTROL / PERSONAL PROTECTION
Provide adequate ventilation, including appropriate local extraction, to ensure that the defined occupational exposure
limit is not exceeded.
Considerations should be given to the work procedures involved and the potential extent of exposure as they may
determine whether a higher level of protection is required.
The following information is given as general guidance.
RESPIRATORS: Wear suitable respiratory protective equipment if exposure to levels above the occupational exposure
limit is likely. A suitable mask with filter type A may be appropriate. In the event of formation of
particularly high levels of vapor a self-contained breathing apparatus may be appropriate.
EYE PROTECTION: Safety glasses or chemical splash goggles.
GLOVES: Wear suitable gloves. Rubber or latex gloves offer the best protection. Gloves should be changed regularly
and if excessive exposure has occurred.
OTHER: Wear suitable protective clothing.
