for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical
attention immediately.
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.

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.
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.
Extremely flammable aerosol. In a fire or if heated, a pressure increase will occur and
the container may burst, with the risk of a subsequent explosion. Gas may accumulate
in low or confined areas or travel a considerable distance to a source of ignition and
flash back, causing fire or explosion. Bursting aerosol containers may be propelled
from a fire at high speed. Runoff to sewer may create fire or explosion hazard.
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
carbonyl halides
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. Shut off all ignition sources. No
flares, smoking or flames in hazard area. Avoid breathing vapor or mist. Provide
adequate ventilation. Wear appropriate respirator when ventilation is inadequate. Put
on appropriate personal protective equipment (see Section 8).
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. Use spark-proof tools and
explosion-proof equipment. 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.

6. Accidental release measures
Stop leak if without risk. Move containers from spill area. Use spark-proof tools and
explosion-proof equipment. 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.
Store in accordance with local regulations. Store in a segregated and approved area.
Store away from direct sunlight in a dry, cool and well-ventilated area, away from
incompatible materials (see Section 10) and food and drink. Eliminate all ignition
sources. Use appropriate containment to avoid environmental contamination.
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. Store and use away from heat, sparks, open flame or any other ignition
source. Use explosion-proof electrical (ventilating, lighting and material handling)
equipment. Use non-sparking tools. Empty containers retain product residue and can
be hazardous.

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: chemical splash goggles.
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. The engineering controls also need to keep gas,
vapor or dust concentrations below any lower explosive limits. Use explosion-proof
ventilation equipment.
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.
