It begins with understanding the differences between hazard, exposure and risk or danger – the importance of considering product use and exposure and the limitations of using a hazard-only decision making process when selecting building materials. This article also will describe some tools, guidance and resources available for evaluating products and materials to help achieve both a high quality construction project, and one that is safe for building occupants. Finally, this article will provide information to help you use building materials safely.
