Extinguishing Media - For powder fires, smother with dry sand, dry dolomite, ABC extinguisher, or flood with water

Special Fire Fighting Procedures - Powder Fire, confined to small area, use respirator approved for toxic dusts and fumes. Large Fire, Fire fighter should use self-contained breathing apparatus.

Unusual Fire and Explosion Hazards - Dust may present fire or explosion hazard under rate favoring conditions or particle size, dispersion and strong ignition source. However, this is not expected to be a problem under normal conditions.

Section VI - Health Hazard Data

Route(s) of Exposure: Grinding Cemented carbide product will produce dust of potentially hazardous ingredients which can be inhaled swallowed or come in contact with the skin or eyes.

Health Hazards (Acute and Chronic): It is reported that cobalt dust is the most probable cause of such respiratory diseases. Symptoms include productive cough, wheezing, shortness of breath, chest tightness and weight loss. Interstitial fibrosis (lung scarring) can lead to permanent disability or death. Certain pulmonary conditions may be aggravated by exposure.

Carcinogenic Assessment: (NPT Annual Report, IRAC Monograms, other): None of the components of this material have been identified as known or suspect carcinogens by NPT, IRAC, or OSHA.

Effects of Overexposure: Inhalation: Dust from grinding can cause irritation of the nose and it also has the potential for causing Transient or permanent respiratory diseases, including occupational asthma and interstitial fibrosis, in a small percentage of exposed individual

Medical Conditions Generally Aggravated by Exposure: Skin contact: can cause irritation or an allergic skin rash due to cobalt sensitization. Certain skin conditions such as dry skin, may be aggravated by exposure.

Eye Contact: Can cause irritation

Ingestion: Reports outside the industry suggest that ingestion of significant amounts of cobalt has the potential for causing blood, heart and other organ problems.

Emergency and First Aid Procedures - Inhalation: If symptoms of pulmonary involvement develop (Coughing, wheezing, etc.), remove from exposure and seek medical attention.

Skin Contact: If irritation or rash occurs, wash affected area with soap and water and isolate from exposure. If condition persist seek medical attention.

Eye Contact: If irritation occurs, flush with copious amounts of water. If condition persist, seek medical attention.
Ingestion: If substantial quantities are swallowed, dilute with a large amount of water, induce vomiting, seek medical attention.

Section VII - Precautions for Safe Handling and Use

Steps to Be Taken in Case Material is Released or Spilled - Ventilate area of spill. Clean up using methods which avoid dust generation such as vacuum (with appropriate filter to prevent airborne dust levels which exceed the PEL or TVL). wet dust mop or wet clean up. If airborne dust is generated use an appropriate NIOSH approved respirator.

Waste Disposal Method - Dispose of in accordance with appropriate government regulations. May be sold as scrap for reclaim.

Precautions to Be taken in Handling - Maintain good housekeeping procedures to prevent dust accumulation during grinding. Avoid dust inhalation and dire skin contact with the dust. Do not strike product with hardened steel hammer or similar device because of possible fracture/shattering of product. Product should be pressed if inserted into another metal part or product.

Other Precautions: Clean up using methods which avoid dust generation such as vacuum (with appropriate filter to prevent airborne dust levels which exceed the PEL or TVL) wet dust mop or wet clean up. If airborne dust is generated use an appropriate NIOSH approved respirator.

Section VIII - Control Measures

Respiratory Protection(Specify Type) Use an appropriate NIOSH approved respirator if airborne dust concentrations exceed appropriate PEL or TLV. All appropriate requirements set forth in 29 CFR 1910.134 should be met.

Ventilation - Use local exhaust ventilation which is adequate do not exceed the PEL or TLV. If such equipment is not available, respirators as specified above.

Protective Gloves - Protective gloves or Barrier cream are recommended when contact with dust or mist is likely. Prior to applying the barrier cream or protective gloves, wash thoroughly.

Eye Protection - Safety glasses with side shields or goggles should be worn.

Work/Hygenic Practices - Wash hands thoroughly after handling, before eating or smoking. Wash exposed skin at the end of work shift. Do not shake clothing, rags or other items to remove dust. Dust should be removed by washing or vacuuming.
