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.

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:
metal oxide/oxides
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. Provide adequate ventilation.
Wear appropriate respirator when ventilation is inadequate. Put on appropriate
personal protective equipment (see Section 8).
Move containers from spill area. Approach release from upwind. Prevent entry into
sewers, water courses, basements or confined areas. Avoid dust generation. Do not
dry sweep. Vacuum dust with equipment fitted with a HEPA filter and place in a closed,
labeled waste container. Dispose of via a licensed waste disposal contractor. 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
:
Move containers from spill area. Avoid dust generation. Do not dry sweep. Vacuum
dust with equipment fitted with a HEPA filter and place in a closed, labeled waste
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 ingest. Avoid contact with eyes, skin and clothing. 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.

Use a properly fitted, particulate filter 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
:
Good general ventilation should be sufficient to control worker exposure to airborne
contaminants.
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.
