Guidance on Safe Use
Administrative data
First-aid measures
Inhalation : Get medical attention immediately. Move exposed person to fresh air. If it is suspected that fumes are still present, the rescuer should
wear an appropriate mask or self-contained breathing apparatus. Keep person warm and at rest. If not breathing, if breathing is irregular or if
respiratory arrest occurs, provide artificial respiration or oxygen by trained personnel. It may be dangerous to the person providing aid to give
mouth-to-mouth resuscitation. If unconscious, place in recovery position and get medical attention immediately. Maintain an open airway. Loosen tight clothing such as a collar, tie, belt or waistband.
Ingestion: Wash out mouth with water. In the event of swallowing, induce patient to drink plenty of water. Get medical attention immediately.
Skin contact: Get medical attention immediately. Flush contaminated skin with plenty of water. Remove contaminated clothing and shoes.
Continue to rinse for at least 10 minutes. Chemical burns must be treated promptly by a physician. Wash clothing before reuse. Clean shoes
thoroughly before reuse.
Eye contact: Immediately flush eyes with running water for at least 15 minutes, keeping eyelids open. Seek immediate medical attention.
Fire-fighting measures
Suitable : In case of fire, use water spray (fog), foam, dry chemical or CO2.
Not suitable : None known.
Special exposure hazards: In a fire or if heated, a pressure increase will occur and the container may burst.
Hazardous combustion products: Decomposition products may include the following materials: sulfur oxides
Special protective
equipment for fire-fighters: Fire-fighters should wear appropriate protective equipment and selfcontained breathing apparatus (SCBA) with a full
face-piece operated in positive pressure mode.
Accidental release measures
Personal precautions: No action shall be taken involving any personal risk or without suitable training. Keep unnecessary and unprotected
personnel from entering. Do not touch or walk through spilt material. Avoid breathing vapour or mist. Provide adequate ventilation. Put on
appropriate personal protective equipment (see section 8).
Environmental precautions: Avoid dispersal of spilt material and runoff and contact with soil, waterways, drains and sewers. Inform the relevant
authorities if the product has caused environmental pollution (sewers, waterways, soil or air).
Large spill : Stop leak if without risk. Move containers from spill area. Prevent entry into sewers, water courses, basements or confined areas.
Contain and collect spillage with non-combustible, absorbent material e.g. sand, earth, vermiculite or diatomaceous earth and place in container
for disposal according to local regulations (see section 13). The spilled material may be neutralized with sodium carbonate, sodium bicarbonate or sodium hydroxide. Dispose of via a licensed waste disposal contractor. Contaminated absorbent material may pose the same hazard as the spilt
product. Note: see section 1 for emergency contact information and section 13 for waste disposal.
Small spill : Stop leak if without risk. Move containers from spill area. Dilute with water and mop up if water-soluble or absorb with an inert dry
material and place in an appropriate waste disposal container. Dispose of via a licensed waste disposal contractor.
Handling and storage
Handling: Put on appropriate personal protective equipment. Eating, drinking and smoking should be prohibited in areas where
this material is handled, stored and processed. Workers should wash hands and face before eating, drinking and smoking. Do not get in eyes or on skin or clothing. Do not breathe vapour or mist. Do not ingest. If during normal use the material presents a respiratory hazard, use only with
adequate ventilation or wear appropriate respirator. Keep in the original container or an approved alternative made from a compatible material,
kept tightly closed when not in use. Keep away from alkalis. Empty containers retain product residue and can be hazardous.
Storage : Store in accordance with local regulations. Store in original container protected from direct sunlight in a dry, cool and wellventilated
area, away from incompatible materials (see section 10) and food and drink. Separate from alkalis. 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.
Packaging materials
Recommended : Use original container.
Remarks : Vent waste air only via suitable separators or scrubbers.

Exposure controls / personal protection
Exposure limit values : Not available.
Recommended monitoring procedures: If this product contains ingredients with exposure limits, personal,workplace atmosphere or biological
monitoring may be required to determine the effectiveness of the ventilation or other control measures and/or the necessity to use respiratory
protective equipment. Reference should be made to European Standard EN 689 for methods for the assessment of exposure by inhalation to
chemical agents and national guidance documents for methods for the determination of hazardous substances.
Risk management measures
Occupational exposure controls
Technical measures : If user operations generate dust, fumes, gas, vapour or mist, use process enclosures, local exhaust ventilation or other
engineering controls to keep worker exposure to airborne contaminants below any recommended or statutory limits.
Personal protection measures
Respiratory protection : Use a properly fitted, air-purifying or air-fed respirator complying with an approved standard if a risk assessment indicates
this is necessary. Respirator selection must be based on known or anticipated exposure levels, the hazards of the product and the safe
working limits of the selected respirator. Recommended: Combination filter, e.g. DIN 3181 ABEK or selfcontained breathing apparatus (SCBA)
Hand protection : Chemical-resistant, impervious gloves complying with an approved standard should be worn at all times when handling chemical
products if a risk assessment indicates this is necessary. After contamination with product change the gloves immediately and dispose of them
according to relevant national and local regulations <1 hours (breakthrough time): Fluorinated rubber - FKM
Eye protection : Safety eyewear complying with an approved standard should be used when a risk assessment indicates this is necessary to avoid
exposure to liquid splashes, mists, gases or dusts. Recommended: Tightly-fitting goggles and face shield
Skin protection : Personal protective equipment for the body should be selected based on the task being performed and the risks involved and
should be approved by a specialist before handling this product. Recommended: chemical-resistant protective suit
Hygiene measures : Wash hands, forearms and face thoroughly after handling chemical products, before eating, smoking and using the lavatory and
at the end of the working period. Appropriate techniques should be used to remove potentially contaminated clothing. Wash contaminated
clothing before reusing. Ensure that eyewash stations and safety showers are close to the workstation location.
Environmental exposure controls
Technical measures : Emissions from ventilation or work process equipment should be checked to ensure they comply with the requirements of
environmental protection legislation. In some cases, fume scrubbers, filters or engineering modifications to the process equipment will be necessary to reduce emissions to acceptable levels.
Stability and reactivity
Stability The product is stable.
Possibility of hazardous reactions: Under normal conditions of storage and use, hazardous reactions will not occur.
Conditions to avoid: Highly reactive with water and alkalis.
Materials to avoid : Attacks many metals producing extremely flammable hydrogen gas which can form explosive mixtures with air. Reactive or
incompatible with the following materials: alkalis
Hazardous decomposition products: Under normal conditions of storage and use, hazardous decomposition products should not be produced.
Disposal considerations
Methods of disposal : Examine possibilities for re-utilisation. Product residues and uncleaned empty containers should be packaged, sealed, labelled,
and disposed of or recycled according to relevant national and local regulations. Where large quantities are concerned, consult the supplier. When
uncleaned empty containers are passed on, the recipient must be warned of any possible hazard that may be caused by residues. For disposal within
the EC, the appropriate code according to the European Waste List (EWL) should be used. It is among the tasks of the polluter to assign the waste to
waste codes specific to industrial sectors and processes according to the European Waste List (EWL).
Hazardous waste : The classification of the product may meet the criteria for a hazardous waste.
