4. First-Aid Measures○ Damage from fumes or dust・ Immediately remove victim to fresh air.
・ If victim has trouble breathing, assist with breathing and seek medical attention.
○ Eye contact
・ If foreign matter enters the eyes, do not rub. Wash out eyes with plenty of water.
・ If irritation persists, seek medical attention.
○ Skin contact
・ Brush off foreign matter with hands and wash the affected area well with water.
・ If irritation persists, seek medical attention.

5. Fire-Fighting Measures
Not applicable (non-combustible)

6. Accidental Release Measures
Product is a solid, so accidental release / spillage is not a concern under normal environmental conditions.

7. Handling and Storage・ No special handling needed, though wearing gloves is recommended when handling products with sharp

corners and edges.
・ In high-humidity locations, store product indoors.

8. Exposure Controls / Personal Protection
Melting, casting, cutting, thermal cutting and grinding are classified as "dusty work" according to
the "Ordinance on Prevention of Hazards Due to Dust," and must be managed accordingly.
・ Keep source of dust sealed, or install local exhaust ventillation system
・ Wear respiratory protective equipment
・ Periodically clean up accumulated dust
・ If dust gets on work clothes, clean clothes by washing・ Wash hands and gargle after working
