| HEALTH HAZARD DATA | |
ROUTES OF EXPOSURE:
GRINDING CEMENTED TUNGSTEN CARBIDE PRODUCT WITH COBALT BINDER MAY PRODUCE
DUST OF POTENTIALLY HAZARDOUS INGREDIENTS WHICH CAN BE INHALED, SWALLOWED
OR COME IN CONTACT WITH THE SKIN OR EYES.
INHALATION:
DUST FROM GRINDING CAN CAUSE IRRITATION OF THE NOSE AND THROAT. IT ALSO
HAS THE POTENTIAL FOR CAUSING TRANSIENT OR PERMANENT RESPIRATORY DISEASE,
INCLUDING OCCUPATIONAL ASTHMA AND INTERSTITIAL FIBROSIS, IN A SMALL
PERCENTAGE OF EXPOSED INDIVIDUALS. 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.
SKIN CONTACT:
CAN CAUSE IRRITATION OR AN ALLERGIC SKIN RASH IN COBALT HYPERSENSITIZED
INDIVIDUALS.
EYE CONTACT: CAN CAUSE MILD PAIN OR 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.
CHRONIC EXPOSURE:
PROLONGED, REPEATED INHALATION OF DUSTS MAY EXACERBATE PRE-EXISTING
PULMONARY AND SKIN DISEASES OR IMPAIRED LIVER AND KIDNEY FUNCTIONS.
| EMERGENCY AND FIRST AID PROCEDURES APPLICABLE FOR DUSTS | |
AND/OR MISTS
INHALATION:
IF SYMPTOMS OF PULMONARY INVOLVEMENT DEVELOP (COUGHING, WHEEZING, SHORTNESS
OF BREATH, ETC.), REMOVE FROM EXPOSURE AND SEEK MEDICAL ATTENTION.
SKIN CONTACT:
IF IRRITATION OR RASH OCCURS, THOROUGHLY WASH AFFECTED AREA WITH SOAP AND
WATER AND ISOLATE FROM EXPOSURE. IF IRRITATION OR RASH PERSISTS, SEEK
MEDICAL ATTENTION.
EYE CONTACT:
IF IRRITATION OCCURS, FLUSH WITH COPIOUS AMOUNTS OF WATER. IF IRRITATION
PERSISTS, SEEK MEDICAL ATTENTION.
INGESTION:
IF SUBSTANTIAL QUANTITIES ARE SWALLOWED, DILUTE WITH LARGE AMOUNTS OF
WATER, DO NOT INDUCE VOMITING AND SEEK MEDICAL ATTENTION.
CARCINOGENIC ASSESSMENT (NTP ANNUAL REPORT, IARC MONOGRAPHS, OTHER):
NONE OF THE COMPONENTS OF THIS MATERIAL HAVE BEEN IDENTIFIED AS KNOWN OR
SUSPECTED CARCINOGENS BY NTP, IARC OR OSHA.
NOTES TO PHYSICIAN:
EMPLOYEES REGULARLY EXPOSED TO DUSTS SHOULD HAVE PERIODIC MEDICAL
EXAMINATIONS WITH PULMONARY FUNCTION EMPHASIZED, AND THEY SHOULD BE
CERTIFIED BY A PHYSICIAN AS TO THEIR FITNESS TO WEAR RESPIRATORS.
PERSONS WITH PRE-EXISTING PULMONARY, SKIN, LIVER, KIDNEY CONDITIONS
MAY BE AT INCREASED RISK FROM EXPOSURE TO DUSTS.
| FIRE AND EXPLOSION HAZARD DATA | |
FLASH POINT: N/A
TEST METHOD USED:
FLAMMABLE LIMITS: N/A
LEL:
UEL:
HARD CEMENTED TUNGSTEN CARBIDE PRODUCT IS NOT A FIRE HAZARD. DUSTS
GENERATED IN GRINDING OPERATIONS MAY IGNITE IF ALLOWED TO ACCUMULATE
AND ARE SUBJECTED TO AN IGNITION SOURCE.
EXTINGUISHING MEDIA:
FOR POWDER FIRES, SMOTHER WITH DRY SAND, DRY DOLOMITE, ABC TYPE FIRE
EXTINGUISHER OR FLOOD WITH WATER.
SPECIAL FIRE FIGHTING PROCEDURES:
FOR A POWDER FIRE CONFINED TO A SMALL AREA, USE A RESPIRATOR APPROVED
FOR TOXIC DUSTS AND FUMES. FOR A LARGE FIRE, FIRE FIGHTERS SHOULD USE
SELF-CONTAINED BREATHING APPARATUS.
UNUSUAL FIRE AND EXPLOSION HAZARDS:
DUSTS MAY PRESENT A FIRE OR EXPLOSION HAZARD UNDER RARE FAVORING CONDITIONS
OF PARTICLE SIZE, DISPERSION AND STRONG IGNITION SOURCE. HOWEVER, THIS IS
NOT EXPECTED TO BE A PROBLEM UNDER NORMAL HANDLING CONDITIONS.

| SPILL OR LEAK PROCEDURES | |
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 OSHA PEL OR THE ACGIH TLV),
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.
| SPECIAL PROTECTION INFORMATION | |
RESPIRATORY PROTECTION:
USE AN APPROPRIATE NIOSH APPROVED RESPIRATOR IF AIRBORNE DUST
CONCENTRATIONS EXCEED THE APPROPRIATE OSHA PEL OR THE ACGIH
TLV. ALL APPROPRIATE REQUIREMENTS SET FORTH IN 29 CFR 1910.134
SHOULD BE MET.
VENTILATION:
USE LOCAL EXHAUST VENTILATION WHICH IS ADEQUATE TO LIMIT PERSONAL EXPOSURE
TO AIRBORNE DUST LEVELS WHICH DO NOT EXCEED THE OSHA PEL OR THE ACGIH TLV.
IF SUCH EQUIPMENT IS NOT AVAILABLE, USE 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 USE OF PROTECTIVE
GLOVES, WASH THOROUGHLY.
EYE PROTECTION:
SAFETY GLASSES WITH SIDE SHIELDS OR GOGGLES ARE RECOMMENDED.
OTHER PROTECTIVE EQUIPMENT: N/A
| SPECIAL PRECAUTIONS | |
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORAGE:
MAINTAIN GOOD HOUSEKEEPING PROCEDURES TO PREVENT DUST ACCUMULATION DURING
GRINDING. AVOID DUST INHALATION AND DIRECT SKIN CONTACT WITH DUST.
OTHER PRECAUTIONS:
CLEAN UP USING METHODS WHICH AVOID DUST GENERATION SUCH AS VACUUM (WITH
APPROPRIATE FILTER TO PREVENT AIRBORNE DUST LEVELS WHICH EXCEED THE OSHA
PEL OR THE ACGIH TLV), WET DUST MOP OR WET CLEAN-UP. IF AIRBORNE DUST IS
GENERATED, USE AN APPROPRIATE NIOSH APPROVED RESPIRATOR.
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 (WITH APPROPRIATE FILTERS) THE CLOTHING, RAGS, OR OTHER
ITEMS.
PERIODIC MEDICAL EXAMINATIONS ARE RECOMMENDED FOR INDIVIDUALS REGULARLY
EXPOSED TO DUST OR MIST.
