Main target for the unannounced checks are sites where refurbishment projects or repair works are underway.
Safe working at height, management of dust risks and provision of adequate welfare facilities are among the topics that inspectors have been briefed to check.
HSE chief inspector of construction Heather Bryant said: “Too many people die or are seriously injured every year on Britain’s construction sites as a result of entirely avoidable incidents. Just as importantly, workers are unnecessarily being exposed to serious health risks, such as asbestos or silica dust, which can have fatal or debilitating consequences.
“Often we find it is smaller companies working on refurbishment and repair work who are failing to protect their workers through a lack of awareness and poor control of risks.
“This initiative provides a chance to engage with these firms to help them understand what they need to do, so they can put in place the practical measures needed to keep people safe.”
