SECTION 2: HAZARDS IDENTIFICATION

2.1. Classification of the Substance or Mixture

Classification (GHS-US)

Within the meaning of the OSHA Hazard Communication Standard [29 CFR 1910.1200]: this product
is considered a manufactured article and is not considered a hazard when used in a manner which
is consistent with the labeled directions.

2.2. Label Elements GHS-US Labeling No labeling applicable

2.3. Other Hazards

During normal operation and usage, cemented carbide products do not present inhalation, ingestion, or
other chemical hazards. However, operations such as grinding, cutting, burning, and welding of such
products may release dusts, fumes, or vapors which may present health hazards. The health hazards
described below relate to these non-routine operations, as well as exposure to component materials.
Wet or dry grinding of cemented carbide products will produce dusts of potentially hazardous ingredients
which can be inhaled, swallowed, or come in contact with the skin or eyes. During wet grinding, the dust
can be suspended or dissolved in the coolant mist.

SECTION 4: FIRST AID MEASURES

4.1. Description of First Aid Measures

First-aid Measures General: Never give anything by mouth to an unconscious person. If you feel
unwell, seek medical advice.

First-aid Measures After Inhalation: When symptoms occur: go into open air and ventilate suspected
area. Obtain medical attention if breathing difficulty persists.

First-aid Measures After Skin Contact: Wash with plenty of soap and water. Obtain medical
attention if irritation develops or persists.

First-aid Measures After Eye Contact: Rinse cautiously with water for several minutes. Remove
contact lenses, if present and easy to do. Continue rinsing.

First-aid Measures After Ingestion: If substantial quantities are swallowed, dilute with large
amount of water. Induce vomiting and seek medical attention.

4.2. Most important symptoms and effects, both acute and delayed

Symptoms/Injuries: None expected under normal conditions of use.

Symptoms/Injuries After Inhalation: Dust from this product may cause irritation to the respiratory tract.

Symptoms/Injuries After Skin Contact: Dust may cause irritation in skin folds or by contact in
combination with tight clothing. Skin exposure can cause an allergic red rash (cobalt itch).

Symptoms/Injuries After Eye Contact: Eye contact with dust may cause mechanical irritation.

Symptoms/Injuries After Ingestion: Ingestion is likely to be harmful or have adverse effects.

Chronic Symptoms: Chronic exposure to respirable dust containing cobalt and tungsten carry the
potential to cause permanent respiratory diseases, including occupational asthma, interstitial
pneumonitis and fibrosis (hard-metal disease), and emphysema. Symptoms include productive
cough, wheezing, dyspnea (upon exertion), pleuritic chest pain, and weight loss. Reports outside
the industry suggest that ingestion of significant amounts of cobalt can cause blood, heart, and
other organ effects. Cobalt metal with tungsten carbide is listed by IARC as Group 2A - probably
carcinogenic to humans. Nickel is listed by IARC as Category 2B possibly carcinogenic to humans.
Cobalt is listed by ACGIH as an animal carcinogen (A3). Cobalt and nickel are known to the State
of California to cause cancer. Nickel is considered reasonably anticipated to be a carcinogen by NTP.

4.3. Indication of Any Immediate Medical Attention and Special Treatment Needed If medical
advice is needed, have product container or label at hand.

SECTION 5: FIRE-FIGHTING MEASURES

5.1. Extinguishing Media

Suitable Extinguishing Media: Dry chemical powder, alcohol-resistant foam, carbon dioxide (CO2).

Unsuitable Extinguishing Media: Do not use a heavy water stream. Use of heavy stream of
water may spread fire.


5.2. Special Hazards Arising From the Substance or Mixture Fire Hazard: Not considered
flammable but may burn at high temperatures.

Explosion Hazard: Dusts may present a fire or explosion hazard under rare favoring conditions
of particle size, dispersion, concentration, and strong ignition source. However, this is not expected
to be a problem under normal handling conditions.

Reactivity: Hazardous reactions will not occur under normal conditions.

5.3. Advice for Firefighters

Precautionary Measures Fire: Exercise caution when fighting any chemical fire.

Firefighting Instructions: Do not breathe fumes or vapors from fire.

Protection During Firefighting: For a dust fire confined to a small area, use a respirator approved
for toxic dusts and fumes. For a large fire involving this material, fire fighters should use a self-contained
breathing apparatus.

Other Information: Refer to Section 9 for flammability properties.

SECTION 6: ACCIDENTAL RELEASE MEASURES

6.1.Personal Precautions, Protective Equipment and Emergency- Procedures

6.1.1. For Non-emergency Personnel

Protective Equipment: Use appropriate personal protection equipment (PPE).

Emergency Procedures: Evacuate unnecessary personnel.

6.1.2. For Emergency Responders

Protective Equipment: Equip cleanup crew with proper protection.

Emergency Procedures: Eliminate ignition sources. Ventilate area.

6.2. Environmental Precautions Prevent entry to sewers and public waters.

6.3. Methods and Material for Containment and Cleaning Up

For Containment: Contain and collect as any solid.

Methods for Cleaning Up: Clean up spills immediately and dispose of waste safely. Avoid actions that
cause dust to become airborne during clean-up such as dry sweeping or using compressed air. Use
HEPA vacuum or thoroughly wet with water to clean-up dust. Use PPE described in Section 8. Transfer
spilled material to a suitable container for disposal.

6.4. Reference to Other Sections See heading 8, Exposure Controls and Personal Protection. Concerning
disposal elimination after cleaning, see item 13.

SECTION 7: HANDLING AND STORAGE

7.1. Precautions for Safe Handling

Additional Hazards When Processed: Use care during processing to minimize generation of dust. Avoid dust
production that exceeds permissible exposure limits.

Hygiene Measures: Handle in accordance with good industrial hygiene and safety procedures. Wash hands
and other exposed areas with mild soap and water before eating, drinking, or smoking and again when leaving work.

7.2. Conditions for Safe Storage, Including Any Incompatibilities Storage Conditions: Store in a dry,
cool and well-ventilated place.
