Dust that arises during the construction process is called “construction dust”. People who are exposed for construction dust for a long period of time are at risk to develop several forms of lung problems, allergies and cancer. Today construction dust is a huge problem during the production in Skanska´s renovation projects. Every day workers are exposed of the unhealthy construction dust and it can cause lung problems and diseases after 10-30 years. This is a problem that must be taken into account to obtain a better working environment on Skanska´s building sites. Skanska Sweden AB has given two students the task to investigate possible problems about the spreading of construction dust. The students have made a literature study in construction wood- and quartz dust to try to solve this question. To obtain a reality-based approach of the problem, an observational study was performed on several construction sites as well as interviewing workers and officials. It has become clear that the problem is first and foremost based on a lack of knowledge about construction dust and the many risks that it causes. Based on the information and analyzes, a working method has been made called Kort Information Säkerhet (KIS). This presentation bases has been done to raise awareness and provide further knowledge of construction dust. The information will be carried out by Skanska officials to share the new information to Skanska’s employ’s.
