4. First-Aid Measures
If Inhaled If the high concentration of dust is inhaled or respiratory symptoms (coughs, gasping,shortness of breath, etc.) are experienced, move to fresh air and take a rest with postureeasy to breathe. If breathing difficulties occur, administer oxygen inhalation. If breathinghas stopped, immediately administer artificial respiration and get medical
advice/attention.

protective equipment to minimize exposure.
Environmental Precautions
 Dispose of dust as industrial wastes and prevent release in water systems.
Containment and Cleanup Methods and Equipment
 If there is dust which occur from CBN/Cemented Carbide producing process, isolate thearea and remove with a cleaner equipped with a filter which can take up fine particles
very efficiently. If appropriate removing methods are not available, sweep with water
sprayers or wet mops.
7. Handling and Storage
Handling■ Technical Measures If the disperse of dust containing cobalt or nickel is concerned, provide local exhaust
ventilation and use personal protective equipment to minimize exposure to human body.
■ Precautions for Safe Handling Obtain safety instructions before use.

■ Contact Avoidance Take measures described in “Exposure Controls/Personal Protection.” Do not breathe dust, fume or vapor.
 Do not eat, drink or smoke in handling area.
■ Hygiene Measures
 Wash skin thoroughly after handling.
 Do not release into the environment.
Storage■ Conditions for Safe Storage
 Avoid sudden changes of temperature and high humidity for storage.
 If storing fine powder, dust, and swarf generated by cutting or polishing, cover themwith a cover to prevent dispersal.
■ Materials for Safe Container
 Use materials meeting the specific gravity of Cemented Carbide
