Preventing Silicosis in the Mining Industry

Preventing Silicosis in the Mining Industry

Silicosis can cause difficulty breathing and lead to other medical issues. Learn what practices the Mine and Health Administration recommend to protect workers.

The Mine Safety and Health Administration (MSHA) recently published an alert on protecting workers in the mining industry from the dangers of respirable crystalline silica.

Workers can be exposed to this very small-sized type of silica from “cutting, sawing, grinding, drilling, and crushing stone, rock, concrete, brick, block, and mortar,” OSHA said. When these particles are breathed in, workers can be at risk for diseases like silicosis. Silicosis not only can lead to difficulty breathing, caused by scar tissue, but can also lead to lung cancer, kidney disease and other medical issues.

To reduce the risk for workers, MSHA recommends four best practices.

  1. “Perform air monitoring of worksites.” Air monitoring can give employees and employers the information they need to make decisions about more practices and respiratory protection, MSHA says.
  2. “Install and maintain engineering controls to reduce the amount of silica in the air.” There are multiple engineering controls that can be addressed, including “exhaust ventilation,” “water sprays” and “wet drilling or suppression.”
  3. “Administrative controls are the second line of defense for minimizing silica exposures.” Controls like housekeeping and training are just a few ways to reduce worker exposure to this hazard.
  4. “Provide miners with appropriately selected, properly fitted and NIOSH approved respirators, as engineering controls are installed or updated.” MSHA specifies that these respirators must be “kept clean and properly maintained.”

The National Institute for Occupational Safety and Health has Dust Control Handbooks for Coal Mining and Metal/Nonmetal Mining.
