Date of issue/Date of revision

Section 4. First aid measures
Get medical attention immediately. Call a poison center or physician. Wash out mouth
with water. Remove dentures if any. Remove victim to fresh air and keep at rest in a
position comfortable for breathing. If material has been swallowed and the exposed
person is conscious, give small quantities of water to drink. Stop if the exposed person
feels sick as vomiting may be dangerous. Do not induce vomiting unless directed to do
so by medical personnel. If vomiting occurs, the head should be kept low so that vomit
does not enter the lungs. Chemical burns must be treated promptly by a physician.
Never give anything by mouth to an unconscious person. If unconscious, place in
recovery position and get medical attention immediately. Maintain an open airway.
Loosen tight clothing such as a collar, tie, belt or waistband.
Get medical attention immediately. Call a poison center or physician. Flush
contaminated skin with plenty of water. Remove contaminated clothing and shoes.
Wash contaminated clothing thoroughly with water before removing it, or wear gloves.
Continue to rinse for at least 10 minutes. Chemical burns must be treated promptly by a
physician. Wash clothing before reuse. Clean shoes thoroughly before reuse.
Protection of first-aiders
No action shall be taken involving any personal risk or without suitable training. If it is
suspected that fumes are still present, the rescuer should wear an appropriate mask or
self-contained breathing apparatus. It may be dangerous to the person providing aid to
give mouth-to-mouth resuscitation. Wash contaminated clothing thoroughly with water
before removing it, or wear gloves.
Treat symptomatically. Contact poison treatment specialist immediately if large
quantities have been ingested or inhaled.

Section 6. Accidental release measures
Environmental precautions
Personal precautions, protective equipment and emergency procedures
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.
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. Do not breathe vapor or mist.
Provide adequate ventilation. Wear appropriate respirator when ventilation is
inadequate. Put on appropriate personal protective equipment.
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.

Section 7. Handling and storage
Advice on general
occupational hygiene
Conditions for safe storage,
including any
incompatibilities
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. See also Section 8 for additional information on hygiene
measures.
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. Store locked up. 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). Avoid exposure obtain special instructions before use. Avoid exposure during pregnancy. Do not
handle until all safety precautions have been read and understood. Do not get in eyes
or on skin or clothing. Do not breathe vapor or mist. Do not ingest. 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.

Section 8. Exposure controls/personal protection
Based on the hazard and potential for exposure, select a respirator that meets the
appropriate standard or certification. Respirators must be used according to a
respiratory protection program to ensure proper fitting, training, and other important
aspects of use.
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.
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,
gases or dusts. If contact is possible, the following protection should be worn, unless
the assessment indicates a higher degree of protection: chemical splash goggles and/
or face shield. If inhalation hazards exist, a full-face respirator may be required instead.
Eye/face protection
Respiratory protection
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.
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.
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.
Individual protection measures
Appropriate footwear and any additional skin protection measures should be selected
based on the task being performed and the risks involved and should be approved by a
specialist before handling this product.
