First-aid measures
- General advice: Get medical advice/attention . Show the safety sheet to the doctor who is on duty.
- Following inhalation: Remove victim to fresh air and keep at rest in a position comfortable for breathing. Get medical advice/attention
- Following skin contact: Wash with plenty of soap and water. Get medical advice/attention
- Following eye contact: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing . Get medical advice/attention
- Following ingestion: rinse mouth. Do NOT induce vomiting .Get medical advice/attention
Most important symptoms and effects, both acute and delayed:
Harmful if swallowed.
Indication of any immediate medical attention and special treatment needed:
Symptomatic treatment.
Fire-fighting measures
- Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry powder or carbon dioxide.
- Unsuitable extinguishing media: Do not use direct water jet.
Special hazards arising from the substance or mixture:
Carbon oxides.
Advice for firefighters:
Use self-contained breathing apparatus for fire fighting.
Accidental release measures
Use personal protective equipment. Avoid the formation of dust. Avoid breathing vapors / fog / gas/ dust. Ensure proper ventilation. Evacuate personnel to safe zones.
Environmental precautions:
Prevent new leaks or spills if it can be done without risk. Do not let the product enter the sewage system. The discharge into the environment should be avoided.
Methods and material for containment and cleaning up:
Collect and prepare the elimination without causing dust. Clean and shovel. Save in appropriate and closed containers for disposal.
Handling and storage
Avoid contact with eyes and skin. Avoid the formation of dust and aerosols.It must have adequate extraction in those places where dust is formed. Normal preventive fire protection.
Conditions for safe storage, including any incompatibilities :
Store in a cool place. Keep the container tightly closed in a dry and well ventilated place.

Exposure controls / personal protection
It contains no substances with occupational exposure limit values.
Exposure controls:
- Appropriate engineering controls: Handle with appropriate industrial hygiene precautions, and respect safety practices.
Wash your hands before breaks and after finishing the workday.
- Individual protection measures, such as personal protective equipment:
- Eye/face protection: Safety glasses with side shields (EN166).
- Hand protection: Wear protective gloves (EN 374).
- Skin protection: Full chemical protection suit.
- Respiratory protection: For annoying exposures, wear a particle respirator, type P1 (EN 143). For a higher level of protection, use respirator cartridges, type ABEK-P2 (EN 143).
- Environmental exposure controls: Prevent new leaks or spills if it can be done without risk. Do not let the product enter the sewer system. Discharge into the environment must be avoided.
