Not to be used for safety reasons: Strong water jet
Specific hazards arising from the chemical
Burning produces heavy smoke. Fire may produce irritating and/or toxic gases. In the event of fire and/or explosion do not breathe
fumes. May cause sensitization by skin contact.
Special protective equipment for fire-fighters
Wear self-contained breathing apparatus and protective suit. Cool containers with flooding quantities of water until well after fire is
out. Do not allow run-off from fire-fighting to enter drains or water courses.
Section 6: ACCIDENTAL RELEASE MEASURES
Personal precautions, protective equipment and emergency procedures
Personal precautions
Avoid breathing vapors or mists. Use personal protective equipment as required. Avoid contact with skin, eyes or clothing.
For emergency responders
Use personal protection recommended in Section 8.
Environmental precautions
Do not allow into any sewer, on the ground or into any body of water. If the product contaminates lakes, rivers or sewage, inform
appropriate authorities in accordance with local regulations. Prevent further leakage or spillage if safe to do so. Local authorities
should be advised if significant spillages cannot be contained.
Methods and material for containment and cleaning up
Methods for containment
Prevent further leakage or spillage if safe to do so.
Product Code 27037.01 Page 3 / 8 AGHS – USA OSHA SDS
Methods for cleaning up
Dispose of waste product or used containers according to local regulations. Clean with detergents. Avoid solvent cleaners. Dam
up. Pick up and transfer to properly labeled containers. Clean contaminated surface thoroughly. Take up mechanically, placing in
appropriate containers for disposal. Contain and collect spillage with an electrically protected vacuum cleaner or by wet-brushing
and place in container for disposal according to local regulations (see section 13).
Section 7: HANDLING AND STORAGE
Precautions for safe handling
Advice on safe handling
Use personal protection recommended in Section 8. Never use pressure to empty container. Comply with the health and safety at
work laws. Prevent product from entering drains. Use only with adequate ventilation. Do not breathe
dust/fume/gas/mist/vapors/spray.
General Hygiene Considerations
When using do not eat, drink or smoke. Wash contaminated clothing before reuse. Avoid contact with skin, eyes or clothing.
Conditions for safe storage, including any incompatibilities
Storage Conditions
Keep/store only in original container. Store in accordance with local regulations. Keep unauthorized personnel away. Containers
that have been opened must be carefully resealed and kept upright to prevent leakage. Keep container tightly closed in a dry and
well-ventilated place.

Appropriate engineering controls
Engineering Controls
Ensure adequate ventilation, especially in confined areas. Provide local exhaust ventilation. In case of insufficient ventilation, wear
suitable respiratory equipment.
Individual protection measures, such as personal protective equipment
Eye/face protection
Tight sealing safety goggles.
Skin and body protection
Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin
contact.
Hand Protection
There is no one glove material or combination of materials that will give unlimited resistance to any individual or combination of
chemicals. Ensure that the breakthrough time of the glove material is not exceeded. Refer to glove supplier for information on
breakthrough time for specific gloves. The instructions and information provided by the glove manufacturer on use, storage,
maintenance and replacement must be followed. Gloves should be replaced regularly and if there is any sign of damage to the
glove material. Always ensure that gloves are free from defects and that they are stored and used correctly. The performance
or effectiveness of the glove may be reduced by physical / chemical damage and poor maintenance. Wear protective gloves.
Respiratory protection
In case of inadequate ventilation wear respiratory protection.
