The National Institute for Occupational Safety and Health (NIOSH) Mining Program, in conjunction with the Industrial Minerals Association–North America, the National Mining Association, and the National Stone, Sand and Gravel Association, recognized four organizations in their respective industry sectors, some for developing new safety tools and systems, and others for instituting new health protocols to keep their workforce safe during the COVID-19 pandemic. For the stone, sand, and gravel category, Lehigh Hanson’s Lowrys Quarry in McConnells, South Carolina won for retrofitting a haul truck to comply with ISO 23875 and improve air quality in the cab.
To reduce dust accumulation and manage CO2 levels, Lowrys Quarry installed a real-time CO2 and pressure monitor, a recirculation filtration system, and an air intake filter. With the new technology in place, the air quality in the cab met or exceeded ISO 23875 requirements. These measures resulted in a healthier work environment for haul truck operators.
“This year’s awards attest to the mining industry’s ability to innovate in response to immediate global challenges while continuing to develop industry-specific health and safety solutions,” says Jessica Kogel, NIOSH associate director for mining.
