Guidance on Safe Use
Administrative data
First-aid measures
- Persons who have come into contact with the material or have breathed in vapours should get immediate medical treatment also in case of delayed symptoms.
- Add all available substance related information.
- Immediately remove any clothing soiled by the product.
- Involve doctor immediately.
- In case of irregular breathing or respiratory arrest provide artificial respiration.
After inhalation: In case of unconsciousness place patient stably in side position for transportation.
After skin contact: Seek medical treatment.
After eye contact: Call a doctor immediately. Protect unharmed eye. Rinse opened eye for several minutes under running water.
After swallowing: Call a doctor immediately.
Fire-fighting measures
- CO₂, powder or water spray. Fight larger fires with water spray or alcohol resistant foam.
For safety reasons unsuitable extinguishing agents:
- No restriction in large fires.
Special hazards arising from the substance or mixture:
- In case of fire, the following can be released:
- Carbon monoxide (CO), Nitrogen oxides (NOx)
Advice for firefighters: Protective equipment:
- Wear self-contained respiratory protective device.
- Chemical resistant protective suit.
- Under the protective suit a fire protective suit according to EN 469 should be applied.
- Use chemical protective suit and self contained breathing apparatus while undressing contaminated co-workers or handling contaminated equipment.
Accidental release measures
- Wear protective clothing.
- Avoid contact with eyes and skin and clothes
- Keep people at a distance and stay on the windward side.
- Access only for trained personnel with personal protective equipment.
- Use respiratory protective device against the effects of fumes/dust/aerosol.
- Ensure adequate ventilation.
Environmental precautions:
- Dilute with plenty of water.
- Keep contaminated washing water and dispose of appropriately.
- Do not allow undiluted product or large quantities of it to reach ground water, water course or sewage system.
Methods and material for containment and cleaning up:
- Absorb with liquid-binding material (sand, diatomite, acid binders, universal binders, sawdust).
- Ensure adequate ventilation.
- Put damaged containers into recovery drums.
- Do not refill spilled product into original container.
Handling and storage
- Empty containers must not be used for other products.
- Contaminated protective equipment should be cleaned before taking it off.
- Ensure good ventilation/exhaustion at the workplace.
- Prevent formation of aerosols.
- Fill only in dedicated and assigned containers.
- Keep containers tightly sealed.
Information about fire - and explosion protection:
- No special measures required.
Conditions for safe storage, including any incompatibilities:
Storage
Requirements to be met by storerooms and receptacles:
- Store in a dry location, keep away from humidity.
- Store in a cool location.
Corrosion of metals:
- No corroding action on metals (expert statement).
Information about storage in one common storage facility:
- Store away from oxidising agents.
Further information about storage conditions:
- Protect from heat and direct sunlight.
Maximum storage temperature:
- No data available.
Recommended storage temperature:
- Currently no data available.
- It is therefore recommended not to exceed room temperature (max. 25°C) during storage over a longer period of time.
Acceptable storage time:
- No data available.
