EC number: 212-133-3
CAS number: 764-99-8
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.
On contact with eyes:
Wash affected eyes for at least 15 minutes under running water with eyelids held open.
Rinse mouth and then drink plenty of water.
Indication of any immediate medical attention and special treatment needed
Treatment: Symptomatic treatment (decontamination, vital functions).
Suitable extinguishing media:
carbon dioxide, dry powder, water spray, alcohol-resistant 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 a self-contained breathing apparatus.
Cool endangered containers with water-spray. 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. Avoid inhalation. Sources of ignition should be kept well clear.
Do not discharge into drains/surface waters/groundwater.
Methods and material for containment and cleaning up
For large amounts: Dike spillage. Pump off product.
For residues: Pick up with suitable absorbent material (e.g. sand, sawdust, general-purpose binder, kieselguhr).
Avoid sources of ignition. Wear suitable protective equipment. Dispose of absorbed material in accordance with regulations.
Precautions for safe handling
Ensure thorough ventilation of stores and work areas. Protect from direct sunlight. Wear suitable gloves and eye/face protection.
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.
Suitable materials for containers: Stainless steel 1.4301 (V2), Stainless steel 1.4401, glass, Carbon steel (Iron)
Unsuitable materials for containers: Paper/Fibreboard
Further information on storage conditions: Keep container tightly closed in a cool, well-ventilated place. Keep away from sources of ignition - No smoking.
Storage temperature: <= 25 °C
Storage duration: <= 24 Months
The product is stabilized, the shelf life should be noted.
From the data on storage duration in this safety data sheet no agreed statement regarding the warrantee of application properties can be deduced.
potassium hydroxide; caustic potash (CAS Number: 1310-58-3)
Content: 0.01 %
Personal protective equipment
Breathing protection if gases/vapours are formed. Gas filter for gases/vapours of organic compounds (boiling point >65 °C, e. g. EN 14387 Type A)
Chemical resistant protective gloves (EN 374)
Suitable materials also with prolonged, direct contact (Recommended: Protective index 6, corresponding > 480 minutes of permeation time according to EN 374):
butyl rubber (butyl) - 0.7 mm coating thickness
fluoroelastomer (FKM) - 0.7 mm coating thickness
Manufacturer's directions for use should be observed because of great diversity of types.
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.
Safety glasses with side-shields (frame goggles) (e.g. EN 166)
No body protection required if used for intended purpose and satisfying generally accepted industrial hygiene rules.
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 inhalation of vapour. No eating, drinking, smoking or tobacco use at the place of work. Hands and/or face should be washed before breaks and at the end of the shift. Store work clothing separately.
Environmental exposure controls
Do not discharge product into the environment without control.
Strong exothermic reaction with acids.
Corrosion to metals:
Corrosive effects to metal are not anticipated. Study scientifically not justified.
Formation of flammable gases:
Remarks: Forms no flammable gases in the presence of water.
The product is stable if stored and handled as prescribed/indicated.
Possibility of hazardous reactions
Evolution of heat under influence of acids. Polymerization occurs with acids. The product can polymerize if the shelf life or storage temperature are greatly exceeded. Heat develops during polymerization. Ignitable air mixtures can form when the product is heated above the flash point and/or when sprayed or atomized.
Conditions to avoid
Avoid all sources of ignition: heat, sparks, open flame. Avoid direct sunlight. Avoid heat. Avoid humidity.
Substances to avoid: acids
Hazardous decomposition products
Possible decomposition products:
The substances/groups of substances mentioned may be released upon the reaction with water.
Waste treatment methods
Incinerate in suitable incineration plant, observing local authority regulations.
Contaminated packaging should be emptied as far as possible; then it can be passed on for recycling after being thoroughly cleaned.
