The accident is reported to have taken place when a carbon compound ignited. Both the U.S. Occupational Safety and Health Administration (OSHA) and the Chemical Safety Board are investigating the incident. Investigators have taken dust samples as they try to pinpoint the exact cause of the blast and fire.
Carbon black, also known as Lamp black, Furnace black, Thermal black, and Channel black, will likely be a focal point of the investigation. Carbon black is used by industry to strengthen and color rubber. It is also used to color inks, coatings, plastics and leather, and to insulate electrical equipment. In confined spaces, carbon black is considered to be a potential combustible dust hazard.
The ABIH, who administer the Certified Industrial Hygienist (CIH) certification program, recently cosponsored a video about carbon black and exposure risks to workers. “CIHs are uniquely qualified to anticipate, recognize, evaluate and control health hazards, including issues related to carbon black,” reported Tracy Parsons, CIH, Administrative Program Manager at ABIH. “In addition to explosion hazards, inhaling carbon black particles can affect the lungs and possibly result in lung disease. The International Agency for Research on Cancer has classified carbon black as a Group 2B, meaning possibly carcinogenic to humans. We hope this video reminds employers and workers of the possible risks associated with carbon black and that CIHs are trained to evaluate hazards and protect people from these types of hazards.”
