Protecting construction, surface mining workers from silica dust: CPWR publishes new resources
Silver Spring, MD — Three new resources from CPWR – The Center for Construction Research and Training are intended to help prevent silica exposure among construction and surface mining workers who operate mobile equipment in enclosed cabs.
The hazard alert card, toolbox talk, and dealer/rental fact sheet are available in English and Spanish.
In the hazard alert, CPWR advises that, before work begins, cabs of mobile equipment be examined for issues with:
The air filtration system: Inspect filters for damage or airflow bypass.
The cab structure: Inspect daily for any holes, gaps or cracks around doors, windows, joints, controls and power-line entries. Silicone caulk or rubber gaskets can be used to repair and seal damaged areas.
Air pressure: Check the pressure gauge daily to ensure it’s working properly, and monitor the pressure throughout the workday to ensure positive air pressure is maintained and dusty air is kept out.
Enclosed cabs should have a communication system that allows operators to speak with other workers without having to open a door or window. Cabs should be cleaned and properly maintained to ensure proper working order of closing mechanisms, gaskets and all seals.
The toolbox talk tells the story of Grace and the result of her exposure to silica dust at work, and the fact sheet is designed to help businesses that rent or sell equipment understand the requirements of OSHA and Mine Safety and Health Administration standards on silica dust.
