3. Composition/information on ingredients
There are no additional ingredients present which, within the current knowledge of the supplier and in the
concentrations applicable, are classified as hazardous to health or the environment and hence require reporting
in this section.
Wash out mouth with water. Do not induce vomiting unless directed to do so by medical
personnel. Never give anything by mouth to an unconscious person. Get medical
attention immediately.
Treat for possible frostbite. Immediately flush eyes with plenty of water for at least 15
minutes, occasionally lifting the upper and lower eyelids. Check for and remove any
contact lenses. Get medical attention immediately.
May cause frostbite. If frostbite occurs, get medical attention. In case of contact,
immediately flush skin with plenty of water for at least 15 minutes while removing
contaminated clothing and shoes. Wash clothing before reuse. Clean shoes thoroughly
before reuse. Get medical attention immediately.
Move exposed person to fresh air. If not breathing, if breathing is irregular or if
respiratory arrest occurs, provide artificial respiration or oxygen by trained personnel.
Loosen tight clothing such as a collar, tie, belt or waistband. Get medical attention
immediately.
No specific treatment. Treat symptomatically. Contact poison treatment specialist
immediately if large quantities have been ingested or inhaled.
Protection of first-aiders
No action shall be taken involving any personal risk or without suitable training. It may
be dangerous to the person providing aid to give mouth-to-mouth resuscitation.

Use an extinguishing agent suitable for the surrounding fire.
5. Fire-fighting measures
Promptly isolate the scene by removing all persons from the vicinity of the incident if
there is a fire. No action shall be taken involving any personal risk or without suitable
training. Move containers from fire area if this can be done without risk. Use water
spray to keep fire-exposed containers cool.
In a fire or if heated, a pressure increase will occur and the container may burst.
Bursting aerosol containers may be propelled from a fire at high speed.
Special protective
equipment for fire-fighters
Fire-fighters should wear appropriate protective equipment and self-contained breathing
apparatus (SCBA) with a full face-piece operated in positive pressure mode.
Hazardous thermal
decomposition products
Decomposition products may include the following materials:
carbon dioxide
carbon monoxide
halogenated compounds
Flammability of the product
No action shall be taken involving any personal risk or without suitable training.
Evacuate surrounding areas. Keep unnecessary and unprotected personnel from
entering. In the case of aerosols being ruptured, care should be taken due to the rapid
escape of the pressurized contents and propellant. If a large number of containers are
ruptured, treat as a bulk material spillage according to the instructions in the clean-up
section. Do not touch or walk through spilled material. Avoid breathing vapor or mist.
Provide adequate ventilation. Wear appropriate respirator when ventilation is
inadequate. Put on appropriate personal protective equipment (see Section 8).
Stop leak if without risk. Move containers from spill area. Approach release from
upwind. Prevent entry into sewers, water courses, basements or confined areas. Wash
spillages into an effluent treatment plant or proceed as follows. Contain and collect
spillage with non-combustible, absorbent material e.g. sand, earth, vermiculite or
diatomaceous earth and place in container for disposal according to local regulations
(see Section 13). Dispose of via a licensed waste disposal contractor. Contaminated
absorbent material may pose the same hazard as the spilled product. Note: see
Section 1 for emergency contact information and Section 13 for waste disposal.
Environmental precautions
6. Accidental release measures
Avoid dispersal of spilled material and runoff and contact with soil, waterways, drains
and sewers. Inform the relevant authorities if the product has caused environmental
pollution (sewers, waterways, soil or air).
Stop leak if without risk. Move containers from spill area. Dilute with water and mop up
if water-soluble. Alternatively, or if water-insoluble, absorb with an inert dry material and
place in an appropriate waste disposal container. Dispose of via a licensed waste
disposal contractor.
Put on appropriate personal protective equipment (see Section 8). Eating, drinking and
smoking should be prohibited in areas where this material is handled, stored and
processed. Workers should wash hands and face before eating, drinking and smoking.
Remove contaminated clothing and protective equipment before entering eating areas.
Pressurized container: protect from sunlight and do not expose to temperatures
exceeding 50°C. Do not pierce or burn, even after use. Do not ingest. Avoid contact
with eyes, skin and clothing. Avoid breathing gas. Avoid breathing vapor or mist. Use
only with adequate ventilation. Wear appropriate respirator when ventilation is
inadequate. Empty containers retain product residue and can be hazardous.

Store in accordance with local regulations. Store away from direct sunlight in a dry, cool
and well-ventilated area, away from incompatible materials (see Section 10) and food
and drink. Protect from sunlight. Use appropriate containment to avoid environmental
contamination.

AIHA WEEL (United States, 10/2011).
TWA: 1000 ppm 8 hours.
8. Exposure controls/personal protection
Use a properly fitted, air-purifying or air-fed respirator complying with an approved
standard if a risk assessment indicates this is necessary. Respirator selection must be
based on known or anticipated exposure levels, the hazards of the product and the safe
working limits of the selected respirator.
Safety eyewear complying with an approved standard should be used when a risk
assessment indicates this is necessary to avoid exposure to liquid splashes, mists or
dusts. If contact is possible, the following protection should be worn, unless the
assessment indicates a higher degree of protection: safety glasses with side-shields.
Personal protective equipment for the body should be selected based on the task being
performed and the risks involved and should be approved by a specialist before
handling this product.
Chemical-resistant, impervious gloves complying with an approved standard should be
worn at all times when handling chemical products if a risk assessment indicates this is
necessary. Considering the parameters specified by the glove manufacturer, check
during use that the gloves are still retaining their protective properties. It should be
noted that the time to breakthrough for any glove material may be different for different
glove manufacturers. In the case of mixtures, consisting of several substances, the
protection time of the gloves cannot be accurately estimated.
Use only with adequate ventilation. Use process enclosures, local exhaust ventilation or
other engineering controls to keep worker exposure to airborne contaminants below any
recommended or statutory limits.
Wash hands, forearms and face thoroughly after handling chemical products, before
eating, smoking and using the lavatory and at the end of the working period.
Appropriate techniques should be used to remove potentially contaminated clothing.
Wash contaminated clothing before reusing. Ensure that eyewash stations and safety
showers are close to the workstation location.
Recommended monitoring
procedures
If this product contains ingredients with exposure limits, personal, workplace
atmosphere or biological monitoring may be required to determine the effectiveness of
the ventilation or other control measures and/or the necessity to use respiratory
protective equipment. Reference should be made to appropriate monitoring standards.
Reference to national guidance documents for methods for the determination of
hazardous substances will also be required.
Environmental exposure
controls
Emissions from ventilation or work process equipment should be checked to ensure
they comply with the requirements of environmental protection legislation. In some
cases, fume scrubbers, filters or engineering modifications to the process equipment
will be necessary to reduce emissions to acceptable levels.
