Description of first aid measures
Remove contaminated clothing.
Keep patient calm, remove to fresh air, seek medical attention.
On skin contact:
Wash thoroughly with soap and water. If adverse health effects develop seek medical attention.
On contact with eyes:
Wash affected eyes for at least 15 minutes under running water with eyelids held open. Seek medical attention if necessary.
Rinse mouth immediately and then drink plenty of water, seek medical attention.
Most important symptoms and effects, both acute and delayed
Symptoms: The most important known symptoms and effects are described in the labelling (see section 2 of MSDS) and/or in section 11 of MSDS.
Indication of any immediate medical attention and special treatment needed
Treatment: Treat according to symptoms (decontamination, vital functions), no known specific antidote.
Suitable extinguishing media:
water spray, dry powder, foam
Special hazards arising from the substance or mixture
nitrogen oxides, carbon oxides
The substances/groups of substances mentioned can be released in case of fire. Under certain conditions in case of fire other hazardous combustion products may be generated.
Advice for fire-fighters
Special protective equipment:
Wear self-contained breathing apparatus and chemical-protective clothing.
Collect contaminated extinguishing water separately, do not allow to reach sewage or effluent systems. Dispose of fire debris and contaminated extinguishing water in accordance with official regulations.
Personal precautions, protective equipment and emergency procedures
Use personal protective clothing. Information regarding personal protective measures see, section 8. Ensure adequate ventilation. Avoid contact with the skin, eyes and clothing.
Do not discharge into drains/surface waters/groundwater.
Methods and material for containment and cleaning up
For small amounts: Allow to solidify and sweep/shovel up.
For large amounts: Allow to solidify and sweep/shovel up.
Wear suitable protective equipment. Dispose of absorbed material in accordance with regulations. To clean the floor and all objects contaminated by this material, use plenty of water.
Reference to other sections
Information regarding exposure controls/personal protection and disposal considerations can be found in section "Exposure controls/personal protection" and section "Disposal considerations".
Precautions for safe handling
Ensure thorough ventilation of stores and work areas. Product should be worked up in closed equipment as far as possible. Personal protective equipment should be worn during open handling. Remove contaminated clothing and protective equipment before entering eating areas. Protect from direct sunlight. Protect against heat.
Protection against fire and explosion:
Prevent electrostatic charge - sources of ignition should be kept well clear - fire extinguishers should be kept handy.
Conditions for safe storage, including any incompatibilities
Segregate from acids and acid forming substances.
Further information on storage conditions: Containers should be stored tightly sealed in a dry place.
Storage temperature: 25 °C
Storage duration: 12 Months
From the data on storage duration in this safety data sheet no agreed statement regarding the warrantee of application properties can be deduced.
The product is stabilized, the shelf life should be noted.

Personal protective equipment
Wear respiratory protection if ventilation is inadequate. Combination filter for gases/vapours of organic compounds and solid and liquid particles (f.e. EN 14387 Type A-P2)
Consider the risk management measures as outlined in the exposure scenario.
Chemical resistant protective gloves (EN 374)
Suitable materials for short-term contact (recommended: At least protective index 2, corresponding > 30 minutes of permeation time according to EN 374)
fluoroelastomer (FKM) - 0.7 mm coating thickness
Supplementary note: The specifications are based on tests, literature data and information of glove manufacturers or are derived from similar substances by analogy. Due to many conditions (e.g. temperature) it must be considered, that the practical usage of a chemical-protective glove in practice may be much shorter than the permeation time determined through testing.
Consider the risk management measures as outlined in the exposure scenario.
Safety glasses with side-shields (frame goggles) (e.g. EN 166)
Body protection must be chosen depending on activity and possible exposure, e.g. apron, protecting boots, chemical-protection suit (according to EN 14605 in case of splashes or EN ISO 13982 in case of dust).
General safety and hygiene measures
Handle in accordance with good industrial hygiene and safety practice. Wearing of closed work clothing is required additionally to the stated personal protection equipment. Avoid contact with the skin, eyes and clothing. When using, do not eat, drink or smoke. Hands and/or face should be washed before breaks and at the end of the shift. Gloves must be inspected regularly and prior to each use. Replace if necessary (e.g. pinhole leaks). Take off immediately all contaminated clothing. Wash contaminated clothing before reuse. Store work clothing separately.
