The US-American Occupational Safety and Health Administration (OSHA) has
published seven new educational resources to help employers control exposure to
respirable crystalline silica at construction sites. The new fact sheets
provide information for employers and for workers who operate handheld
grinders, angle grinders, jackhammers, rotary hammers, stationary masonry saws,
handheld masonry saws or vehicle-mounted drilling rigs.
Respirable silica dust is a common hazard at many construction sites. Workers
who breathe high concentrations of silica day after day are at risk of
developing silicosis, a progressive and potentially disabling lung disease.
Exposure to silica dust also can increase the risk of lung cancer and has been
linked to other diseases such as chronic obstructive pulmonary disease, and
kidney and autoimmune diseases.
