Building sites in Berkshire are being inspected in a month-long blitz by the Health and Safety Executive (HSE).
More than 70 people die on construction sites a year
The initiative, which will see officials making unannounced visits, is part of a national campaign to tackle dangerous work practices.
Last year 159 people were injured on construction sites in Berkshire. Of these, 47 were major incidents, such as amputations and dislocations.
Accidents on building sites make up one-in-three of UK industrial deaths.
Andrew Gordon, principal construction inspector for Berkshire, said: "I see the consequences of poor work practices on a daily basis in the Berkshire area.
"My team will be working closely with local construction companies to make them aware of potential dangers and the negative effects they can have on employees and the business itself.
"Everyone has the right to work in decent, safe conditions. Our inspectors will be requiring those in charge of construction sites to ensure that workers can earn a living without risking injury."
