4.3. Indication of any immediate medical attention and special treatment needed
Notes for the doctor Treat symptomatically.

SECTION 5: Firefighting measures
5.1. Extinguishing media
Suitable extinguishing media The product is not flammable. Extinguish with alcohol-resistant foam, carbon dioxide, dry
powder or water fog. Use fire-extinguishing media suitable for the surrounding fire.
Unsuitable extinguishing
media
Do not use water jet as an extinguisher, as this will spread the fire.
5.2. Special hazards arising from the substance or mixture
Specific hazards Containers can burst violently or explode when heated, due to excessive pressure build-up.
Severe corrosive hazard. Water used for fire extinguishing, which has been in contact with the
product, may be corrosive.
Hazardous combustion
products
Thermal decomposition or combustion products may include the following substances: Very
toxic or corrosive gases or vapours.
5.3. Advice for firefighters
Protective actions during
firefighting
Avoid breathing fire gases or vapours. Evacuate area. Keep upwind to avoid inhalation of
gases, vapours, fumes and smoke. Cool containers exposed to heat with water spray and
remove them from the fire area if it can be done without risk. Cool containers exposed to
flames with water until well after the fire is out. If a leak or spill has not ignited, use water
spray to disperse vapours and protect men stopping the leak. Avoid discharge to the aquatic
environment. Control run-off water by containing and keeping it out of sewers and
watercourses. If risk of water pollution occurs, notify appropriate authorities.
Special protective equipment
for firefighters
Regular protection may not be safe. Wear chemical protective suit. Wear positive-pressure
self-contained breathing apparatus (SCBA) and appropriate protective clothing. Firefighter’s
clothing conforming to European standard EN469 (including helmets, protective boots and
gloves) will provide a basic level of protection for chemical incidents.

SECTION 6: Accidental release measures
6.1. Personal precautions, protective equipment and emergency procedures
Personal precautions Wear protective clothing as described in Section 8 of this safety data sheet. No action shall be
taken without appropriate training or involving any personal risk. Avoid inhalation of dust and
vapours. Use suitable respiratory protection if ventilation is inadequate. Avoid contact with
skin and eyes.
6.2. Environmental precautions

Environmental precautions Avoid discharge into drains or watercourses or onto the ground. Avoid discharge to the
aquatic environment.
6.3. Methods and material for containment and cleaning up
Methods for cleaning up Wear protective clothing as described in Section 8 of this safety data sheet. Clear up spills

immediately and dispose of waste safely. This product is corrosive. If the product is soluble in
water, dilute the spillage with water and mop it up. Alternatively, or if it is not water-soluble,
absorb the spillage with an inert, dry material and place it in a suitable waste disposal
container. The contaminated absorbent may pose the same hazard as the spilled material.
Label the containers containing waste and contaminated materials and remove from the area
as soon as possible. Flush contaminated area with plenty of water. Wash thoroughly after
dealing with a spillage. Dangerous for the environment. Do not empty into drains. For waste
disposal, see Section 13.
6.4. Reference to other sections
Reference to other sections For personal protection, see Section 8. See Section 11 for additional information on health
hazards. See Section 12 for additional information on ecological hazards. For waste disposal,
see Section 13.
SECTION 7: Handling and storage
7.1. Precautions for safe handling
Usage precautions Read and follow manufacturer’s recommendations. Wear protective clothing as described in
Section 8 of this safety data sheet. Keep away from food, drink and animal feeding stuffs.
Handle all packages and containers carefully to minimise spills. Keep container tightly sealed
when not in use. Avoid the formation of mists. Avoid contact with acids. Contact with acids
liberates toxic gas. This product is corrosive. Immediate first aid is imperative. Avoid
discharge to the aquatic environment. Do not handle until all safety precautions have been
read and understood. Do not handle broken packages without protective equipment. Do not
reuse empty containers.
Advice on general
occupational hygiene
Wash promptly if skin becomes contaminated. Take off contaminated clothing. Wash
contaminated clothing before reuse.
7.2. Conditions for safe storage, including any incompatibilities

Storage precautions Keep out of the reach of children. Keep away from food, drink and animal feeding stuffs. Keep

glove supplier/manufacturer, who can provide information about the breakthrough time of the
glove material. To protect hands from chemicals, gloves should comply with European
Standard EN374. Considering the data specified by the glove manufacturer, check during use
that the gloves are retaining their protective properties and change them as soon as any
deterioration is detected. Frequent changes are recommended.
