SECTION 2 PRODUCT INFORMATION

Product Name:Cemented Tungsten Carbide
Synonyms: WC, Carbide, Cemented Carbide, Tungsten Carbide
Chemical Formula: WC+Co
Hazardous Composition: Nil.

SECTION 3 HAZARDOUS IDENTIFICATION

Health Hazards: 
No health hazards are known to exist or have been reported from exposure to this material in its usual ‘solid form’, however, grinding a Tungsten Carbide product will produce dust
and powder or a mist of potentially hazardous ingredients which can be inhaled, swallowed, or come in contact with the skin or eyes, and may be subject to combustion.
Environmental Impact: 
No environmentally hazardous effect has been clearly reported about cemented carbide.
Physical & Chemical Impact: 
Cemented Carbide is physically and mechanically stable in its solid form, and no hazards have been reported as regard of conflagration.
No acute hazards or impact have been reported.

SECTION 4 FIRST AID MEASURES

Inhalation: 
Inhalation of carbide dust, powder or mixture may lead to symptoms of pulmonary involvement (coughing, wheezing, dyspnea, etc.). In such case, remove to fresh air. If symptoms persist, seek medical attention. Skin Contact: 
Skin contact might lead to irritation or rash, thorough wash on affected area with soap and water should be applied and isolate from exposure. If irritation or rash persists, seek medical attention. Note: not to rub fibers into skin. Eye Contact: 
Immediate Removal of contact lenses is asked. Flush eyes with large amounts of purified water. If irritation persists, seek medical attention. Ingestion: 
If substantial quantity is swallowed, drink purified water for dilution and immediately seek medical attention.

SECTION 5  FIRE FIGHTING MEASURES

Flash Point: Not applicable
Lower Explosive Limit: Not applicable  Upper Explosive Limit: Not applicable Cemented Tungsten Carbide products are not a fire hazard under normal conditions of use. However, dusts generated in grinding may be sensitive to static discharge or ignite if allowed to accumulate and then are exposed to an ignition source. Extinguishing Media: 
Appropriate dry powder extinguisher can be used with metal dust fires. Special Fire Fighting Procedures: 
Firefighters are required to wear a NIOSH/MSHA approved full-facepiece self-contained breathing apparatus (SCBA) operated in positive pressure mode and full turnout gear. Unusual Fire and Explosion Hazards: 
Dusts or Powder may present a fire or explosion hazard under rare favoring conditions of particle size, dispersion, concentration, or/and strong ignition source. However, this is not expected to be a problem under normal handling conditions.

SECTION 6 ACCIDENTAL RELEASE MEASURES

Clean-up Area: 
Use methods (such as a high efficiency particulate air (HEPA) vacuum, wet dust mop, or wet clean-up) that can avoid dust generation. Operating Personnel: 
Personnel to process work piece or clean up dusts/powders, etc. are required to be in protective clothing including facepiece, etc to alleviate direct or indirect exposure to dusts/powders. Environmental Precaution: 
Wastes such as dusts/powders should be collected instead to be discarded randomly.

SECTION 7 HANDLING AND STORAGE MEASURES

Cemented Tungsten Carbide is physically and chemically stable. Under normal operating conditions, the use of carbide products do not require special safety precautions beyond normal safety procedures for handling and using, such as safety glasses and gloves. However, operations such as grinding, cutting, burning, and welding of carbide products may generate dusts or fumes which may require special handling procedures. Long time using of or frequent exposure to dusts/powders and/or solution with cobalt or/and nickel content might lead to pachylosis. Wash hands thoroughly after handling, and before eating or smoking. Wash exposed skin at the end of the work shift. Smoking and consumption of food or beverages should be restricted from areas where hazardous components may be present. Do not shake clothing, rags, or other items to remove dust. Dust should be removed by laundering or vacuuming (with appropriate filters) the clothing, rags, or other items. Maintain good housekeeping procedures to prevent dust accumulation during grinding. Avoid dust inhalation and direct skin contact with dust. Note: 
Periodic medical monitoring is recommended for individuals regularly exposed to dust or fumes, with particular attention to any potential sensitization effects of such substances

SECTION 8 EXPOSURE CONTROLS, PERSONNEL PROTECTION

Engineering Control: 
Use Protective Appliance such as Face Piece, Aspirator, etc to control aerosol dusts to below standard figure of admissible concentration as per below table.

SECTION 11 TOXICOLOGICAL INFORMATION

Dusts/powders at processing of cemented tungsten carbide may lead to irritation on nose, mouth, eyes, and/or throat, irritation on respiratory organ and lungs. Skin rash, coughing, breathing difficulty might occur. Over-inhalation of cobalt and/or nickel might result in symptoms of blood, heart, thyroid gland and/or splenic organ.
