Summary

Workers in carbide saw blade production may face elevated cobalt exposure, particularly in grinding. Elevated cobalt levels were found in air and urine, with grinding coolant showing high concentrations, suggesting a common issue in the industry.

Area of Science:

  • Occupational Health
  • Industrial Hygiene
  • Toxicology

Background:

  • Past reports link hard metal disease and respiratory symptoms to tungsten and cobalt exposure.
  • This study investigates a small carbide saw blade manufacturing company.

Purpose of the Study:

  • To characterize cobalt exposure in a carbide tip saw blade production facility.
  • To assess airborne and biological cobalt levels and identify exposure sources.

Main Methods:

  • Ambient air monitoring (area and personnel) for cadmium, cobalt, and tungsten.
  • Particle size determination and biological monitoring (urine cobalt levels).
  • Analysis of grinding coolant cobalt concentrations and a survey of other facilities.

Main Results:

Related Experiment Videos

  • Cobalt air levels in the grinding department approached the threshold limit value (0.05 mg/m3).
  • Production workers, especially grinders, showed elevated urine cobalt levels.
  • Grinding coolant had high cobalt concentrations, a potentially common issue in similar shops.

Conclusions:

  • Grinding operations are a significant source of cobalt exposure in this facility.
  • Elevated cobalt in grinding coolant may be widespread in the carbide grinding industry.
  • Further controls are needed to mitigate cobalt exposure risks for workers.
