4. First Aid Measures

Ingestion: Rinse mouth with water, but do not swallow mouthwash. Do not induce vomiting. Give plenty of water to drink (ONLY IN CONSCIOUS PERSONS). Refer for medical attention.
Inhalation: Immediate fresh air & rest. Keep under observation and if breathing becomes difficult seek immediate medical attention. Resuscitate if breathing stops.
Skin Contact: Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eye Contact: First rinse with plenty of water for at least 10 minutes (remove contact lenses if easily possible), ensure lids remain open during flushing, and then seek immediate medical attention.
Other Information: No further relevant information available.

5. Firefighting Measures

Special protective equipment and precautions for fire fighters

Wear self contained breathing apparatus with full face shield operated in positive pressure mode, MSHA/NIOSH (approved or equivalent), and full protective gear.
May produce black acrid smoke if burned.
Forms combustible solid if allowed drying out. Emits corrosive & toxic fumes, including oxides of carbon, & nitrogen during combustion.

6. Accidental Release Measures

Personal precautions, protective equipment and emergency procedures: Use protective equipment as detailed in section 8.
Environmental precautions: Not available.
Methods and materials for containment and clean up: Clean up spills using an absorbent, non-combustible material and gather up placing in a clean closed container for disposal. Do not wash away into sewers.

7. Handling and Storage

Precautions for safe handling: Read the Suppliers' technical data sheet carefully before commissioning or using the product.
Conditions for safe storage: Store unopened package at ambient temperature in a well ventilated place away from heat.

8. Exposure Controls / Personal Protection

Exposure Standards

Engineering controls: No components above the 0.1% threshold have specific workplace control parameters assigned to our knowledge. Local mechanical ventilation not required as supplied, but this is also dependent on other mobile phases and analytes used. Always use a fume cupboard if handling as the dry power or where the liquid component may become airborne.

Personal protective equipment

Eye and face protection: Safety glasses with side-shields conforming to EN 166.
Skin protection: Suitable impervious gloves e.g. Nitrile or Neoprene rubber. The selected protective gloves have to conform to EN 374.
Body protection: Avoid contact of contents with skin and clothing.
Respiratory protection: If required to control exposure, use only suitable respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).
