New HSE report on dust exposure
The Health and Safety Executive (HSE) has published a report on the risks of dust inhaled as a result of construction activities including the use of power tools.
The report, which concludes the HSE investigation into construction dust risks, showed wide variation in exposure levels among workers. All three systems recorded dust readings above HSE’s Workplace Exposure Limit of 0.1 mg.m-3, although this limit relates to an eight-hour working day.
It also includes the results of extensive laboratory tests of three different manufacturers’ dust extraction systems for hand-held electric diamond cutters and levels of respirable crystalline silica (RCS) – a recognised carcinogen.
“Diamond cutters are often used to cut concrete and natural stone, both of which can contain high levels of crystalline silica, in the case of concrete up to 70%,” the report says.
