SECTION 3: HAZARD IDENTIFICATION

Emergency Overview
During normal operation and usage, cemented carbide products do not present inhalation, ingestion, or other chemical hazards. However, non-routine operations such as grinding, cutting, burning, or welding of such products could release dusts or fumes which may present a health hazard, if the exposure limits described in Section 2 are exceeded.

Inhalation: Irritant/Sensitizer: 20 mg (CO)/m3 is immediately dangerous to life and health.
Acute Overexposure: May cause respiratory tract irritation which include wheezing, shortness of breath, and fits of coughing which may produce blood, soreness in the chest, and dust accumulation in the lung. It may also cause weight loss, bronchitis, asthma, and inflammation of or damage to lung tissue.
Chronic Overexposure: May cause build-up of dust in the lungs, allergic respiratory reaction, obstructed airways, and lung damage or disease, with symptoms as described in acute exposure. Previously exposed individuals may be at increased risk.

Skin Contact: Irritant/Sensitizer: in the form of metallurgical powder, dust, or mist from grinding.
Acute Overexposure: May cause irritation with inflammation, rash and itching. It may also cause allergic skin reaction if previously exposed. A rash may develop, usually in the flexor areas of the elbow, neck and face.
Chronic Overexposure: May cause inflammation and/or rash (irritant or allergic contact dermatitis).

Eye Contact: Irritant.
Acute Overexposure: May cause irritation with redness, pain and itching.
Chronic Overexposure: May cause conjunctivitis.

Ingestion: Irritant: in the form of metallurgical powder, dust, or mist from grinding.
Acute Overexposure: May cause abnormally low blood pressure and gastrointestinal irritation with pain, vomiting, and sensations of hotness or nausea. Large doses may cause diarrhea. Severe exposure may cause heart damage, convulsions, or enlargement of the thyroid.
Chronic Overexposure: May adversely affect the pancreas, thyroid gland, heart, or bone marrow.

 


SECTION 4: FIRST AID MEASURES

Inhalation
If symptoms of pulmonary involvement develop (coughing, wheezing, shortness of breath), remove from exposure area to fresh air immediately. If breathing has stopped, perform cardiopulmonary resuscitation (CPR). Keep affected person warm and at rest. Get medical attention immediately.

Skin Contact
If irritation or rash occurs, remove contaminated clothing and shoes immediately. Wash affected areas with soap or mild detergent and large amounts of water until no evidence of material remains. Get medical attention.

Eye Contact
If irritation occurs, wash eyes immediately with large amounts of water, occasionally lifting upper and lower lids, until no evidence of material remains. Get medical attention immediately.

Ingestion
If this material has been swallowed and person is conscious, immediately give person large amounts of water. Do not attempt to make an unconscious person drink or vomit. Induce vomiting only if specifically instructed by a physician. Get medical attention immediately.

 


SECTION 5: FIRE FIGHTING MEASURES

Fire and Explosion Hazards Flash Point: not applicable Explosive Limits: not applicable
Cemented Carbide Products are not a fire hazard under normal conditions of use. However, under rare conditions, finely divided powder/dust or fumes -- from non-routine operations such as grinding, cutting, burning, or welding of such products -- are expected to be a fire and explosion hazard when exposed to high temperatures or ignition sources. Particle size, concentration, dispersion, and ignition source would determine reactivity.

Firefighting Media
For localized dust fires, smother with ABC-type fire extinguisher, dry sand, dry dolomite, sodium chloride, or soda ash or flood with water.

Special Fire Fighting Procedures
Avoid breathing fumes from burning material. Use a NIOSH-approved particulate filter respirator for toxic dusts and fumes.

 


SECTION 6: ACCIDENTAL RELEASE MEASURES

Steps To Be Taken If Material Is Spilled or Released
Clean up area using methods that avoid dust generation such as a high efficiency particulate air (HEPA) vacuum, wet dust mop, or wet cleanup. Residue should be collected in suitable closed containers for later disposal. Use appropriate personal protective equipment including respiratory protection and gloves. Use a NIOSH-approved particulate filter respirator if airborne concentrations could exceed exposure limits listed in Section 2.

 


SECTION 7: HANDLING AND STORAGE

 

Non-routine operations such as grinding, cutting, burning, or welding of Cemented Carbide Products could generate dust or fumes which would require special
handling procedures, as follows:

Handling and Storage
Minimize free fall of powder and avoid dispersion of dust in air. Do not shake clothing, rags, or other items to remove dust. Dust should be removed by washing or vacuuming. Finely divided particles, dust, or fumes may be flammable or explosive. Keep away from sparks or ignition sources. Contents should be stored in a clean area. See Section 13 for disposal methods.

Cleanup
Clean up area using methods that avoid dust generation such as a high efficiency particulate air (HEPA) vacuum, wet dust mop, or wet cleanup. Residue should be collected in suitable closed containers for later disposal. Use appropriate personal protective equipment including respiratory protection and gloves. Use a National Institute of Occupational Safety and Health (NIOSH)-approved respirator if airborne concentrations could exceed exposure limits listed in Section 2.

Other Precautions
Wash hands thoroughly after handling, and before eating or smoking. Periodic medical monitoring is recommended for individuals regularly exposed to dust or
fumes.

 


SECTION 8: EXPOSURE CONTROLS AND PERSONAL PROTECTION

Non-routine operations such as grinding, cutting, burning, or welding of Cemented Carbide Products could generate dust or fumes which would require special handling procedures, as follows:

Ventilation
Provide local (preferable) or general exhaust ventilation to maintain exposure levels below exposure limits listed in Section 2.

Respiratory Protection
Use a NIOSH-approved particulate filter respirator if airborne concentrations could exceed exposure limits listed in Section 2. All appropriate requirements set forth in Federal OSHA Hazards Communications Standard 29 CFR 1910.134 should be met.

Clothing
Use appropriate protective clothing that would prevent repeated or prolonged skin contact with dust particles. Soiled clothing should be laundered separately.

Gloves
Use appropriate protective gloves (leather or rubber) or barrier creams to prevent contact with dust particles.

Eye Protection
Use safety glasses with side shields or dust-proof safety goggles. Contact lenses should not be worn when performing these non-routine operations. Where there is a possibility that the machinist's eyes may be exposed to the particulates, an eyewash fountain within the immediate work area should be provided for
emergency use.
