Many architects, and specifications writers spend long stretches of time at a desk in an office, and are potentially exposed to numerous other work situations that present health and safety hazards when out in the field. There is an entire series of regulations that apply to construction projects, many of which apply to representatives of architectural firms while onsite. It is recommended that architectural firms be familiar with the act and with regulations that apply not only to industrial and construction environments, but also to their own practices.
