Examples of the prevention through design (PTD) concept exist in practice in all industrial sectors, including the construction, manufacturing, healthcare and service industries. Process and design solutions have been developed and implemented to reduce or eliminate risks to occupational safety and health (OSH). Awareness is building that engaging with designers as part of OSH management is an effective practice for reducing injuries, illnesses and fatalities (Manuele, 1997). Effective diffusion and implementation of the PTD concept call for detailed understanding of the principles and practices of both design and OSH. PTD also requires that architects, engineers and designers know the processes, jobs and work conditions associated with their designs and that they understand the associated risks. Within OSH management, PTD is recognized as a top priority. The ability to remove or reduce jobsite hazards and, therefore, eliminate or decrease risk to worker safety and health is an attractive and welcome proposition.
