Guidance on Safe Use
Administrative data
First-aid measures
In all cases of doubt, or when symptoms persist, seek medical attention. If unconscious, place in recovery position and get medical attention immediately. Never give anything by mouth to an unconscious person. In any case show the physician the Safety Data Sheet
Eye contact: Immediately flush eyes with running water for at least 15 minutes, keeping eyelids open. Begin
with medical treatment.
Inhalation: Remove the casualty into fresh air and keep at rest.
Skin contact: Take off immediately all contaminated clothing. Wash contaminated clothing before reusing. Wash
skin thoroughly with soap and water or use recognised skin cleanser.
Ingestion: If swallowed, rinse mouth with water (only if the person is conscious). Do not induce vomiting
unless directed to do so by medical personnel. Seek medical attention.
Most important symptoms and effects, both acute and delayed
General information : No known significant effects or critical hazards.
4.3 Indication of any immediate medical attention and special treatment needed
Notes to physician: No special recommendations.
Fire-fighting measures
Extinguishing media
Suitable: Extinguishing measures to suit surroundings. In case of fire, use water spray jet, dry extinguishing
powder, foam or carbon dioxide.
Not suitable: water jet.
Special hazards arising from the substance or mixture
Hazardous combustion products: In a fire, the following may be released: carbon dioxide, carbon monoxide, nitrogen oxides.
Advice for firefighters
Special protective equipment for fire-fighters: During fire-fighting wear self-contained breathing apparatus and protective clothing.
Additional information :The product is combustible. Use extinguishing media suitable for surrounding materials. Fire
residues and contaminated fire extinguishing water must be disposed of in accordance with local
regulations.
Accidental release measures
Personal precautions, protective equipment and emergency procedures
General information : Avoid the creation of dust. Avoid all possible sources of ignition (spark or flame). Provide adequate
ventilation. Use personal protective equipment.
Environmental precautions
General information : Do not discharge into the drains / surface waters / groundwater. Prevent spread over a wide area e.
g. by containment or oil barriers.
Methods and material for containment and cleaning up
General information : Vacuum or sweep up material and place in a designated, labelled waste container. Disposal of this
product, solutions and any by-products should at all times comply with the requirements of
environmental protection and waste disposal legislation and any regional local authority
requirements.
Handling and storage
Precautions for safe handling
Protective measures : Keep away from sources of ignition. Avoid the creation of dust. Fine dust clouds may form
explosive mixtures with air. Take precautionary measures against electrostatic discharges. Provide
good ventilation of working area.
Conditions for safe storage, including any incompatibilities
General Information: Store in a dry, cool and well-ventilated area. 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 unlabelled containers. Use appropriate containment to avoid
environmental contamination. Store in accordance with local regulations. Eliminate all ignition
sources.

Exposure controls / personal protection
Control parameters
Occupational exposure limits: Not known.
Exposure controls
Hygiene measures : Observe the usual precautions for handling chemicals. When using do not eat, drink or smoke. Use protective skin cream for preventive skin protection. Clean skin thoroughly after work; apply skin cream.
Skin protection: Usual working clothes for the chemical industry, suitable for the job.
Hand protection: Wear protective gloves in cases of prolonged contact (DIN EN 374). Protective gloves should in any case be tested for workplace-specific suitability (e.g. mechanical resistance, product
compatibility, antistatic properties). Comply with instructions and information provided by the glove manufacturer concerning use, care and replacement of the gloves. Replace protective gloves
immediately upon damage or at the first signs of wear. As far as possible, plan work procedures so that wearing gloves will not be necessary.
Respiratory protection: If the occupational exposure limits are exceeded, suitable respiratory protective equipment must be
worn. If no occupational exposure limits are defined, sufficiently effective respiratory protective
measures must be taken in the presence of dust
Stability and reactivity
Stability and reactivity
Reactivity
General information : No specific test data related to reactivity available for this product or its ingredients.
Chemical stability
General information : The product is stable.
Possibility of hazardous reactions
General information : No hazardous reactions when stored and handled according to prescribed instructions.
Conditions to avoid
General information:Store away from direct sunlight. Keep away from heat. Keep away from moisture.
Incompatible materials
General information: oxidising agents
Hazardous decomposition products
General information: Thermal disintegration depends to a great extent on the external conditions. A complex mixture of
solids, liquids and gases forms in the air, including among other substances carbon dioxide, carbon
monoxide and other organic compounds, when this material is burnt or is thermally or oxidatively
degraded.
Disposal considerations
Waste treatment methods
Product
Methods of disposal : The generation of waste should be avoided or minimised wherever possible. Empty containers or
liners may retain some product residues. This material and its container must be disposed of in a
safe way. Dispose of surplus and non-recyclable products via a licensed waste disposal contractor.
Incineration in suitable incineration plant. Disposal of this product, solutions and any by-products
should at all times comply with the requirements of environmental protection and waste disposal
legislation and any regional local authority requirements.
Packaging
Methods of disposal : The generation of waste should be avoided or minimised wherever possible. Waste packaging
should be recycled. Incineration or landfill should only be considered when recycling is not feasible.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
