The accident frequency in the construction industry has shown a downward trend every year but this trend was broken 2010th. It is often lack of precautionary measures within work environment and safety that is the cause of accidents. The big construction companies understand the importance of precautionary measures within work environment and safety, as they spend a lot of money and time on that matter. By examining the work environment and the safety of the small construction companies you can see how they work. The report will presents how these small companies work with work environment and safety, and also how they follow the safety instructions that are available and how they make use of safety equipment. By making use of interviews with staff in small construction companies, information has been collected about how they work with work environment and safety, and how they experience them. An interview with inspector at Swedish Work Environment Authority has been done to get their point of view of the small construction companies. The results show that small construction companies can get better at planning the work environment before construction begins. The constructions sites were kept clean to avoid falls. It appeared that they sometimes didn’t use harness at small jobs on the roof, but on larger work on the roof they used scaffolds. The reason to the sloppiness of not following the safety rules were time pressure and fast pace.
