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.

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.
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.

Use an extinguishing agent suitable for the surrounding fire.
5. Fire-fighting measures
Extinguishing media
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.
In a fire or if heated, a pressure increase will occur and the container may burst.
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.

Special exposure hazards
:
None known.

Hazardous thermal
decomposition products
:
Decomposition products may include the following materials:

carbon monoxide
metal oxide/oxides
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. 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).
Personal precautions
:
Large spill
:
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.
Small spill
:
Methods for cleaning up
Store in accordance with local regulations. Store in original container protected from
direct sunlight in a dry, cool and well-ventilated area, away from incompatible materials
(see Section 10) and food and drink. Keep container tightly closed and sealed until
ready for use. Containers that have been opened must be carefully resealed and kept
upright to prevent leakage. Do not store in unlabeled containers. 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.
Do not get in eyes or on skin or clothing. Do not ingest. Avoid breathing vapor or mist.
If during normal use the material presents a respiratory hazard, use only with adequate
ventilation or wear appropriate respirator. Keep in the original container or an approved
alternative made from a compatible material, kept tightly closed when not in use. Empty
containers retain product residue and can be hazardous. Do not reuse container.

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: chemical splash goggles.
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.
Personal protection
Eyes
Skin
Respiratory
:
:
:
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.
Hands
:
Engineering measures
:
If user operations generate dust, fumes, gas, vapor or mist, use process enclosures,
local exhaust ventilation or other engineering controls to keep worker exposure to
airborne contaminants below any recommended or statutory limits.
Hygiene measures
:
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.
