This book familiarizes personnel serving as Emergency Managers, Safety Officers, Assistant Safety Officers, and in other safety-relevant Incident Command System (ICS) roles with physical and psychosocial hazards and stressors that may impact the health and safety of workers and responders in an All-Hazards Response, and ways to minimize exposure. This book provides knowledge on regulations and worker safety practices to the Safety Officer with an emergency responder background, and provides the tools for the Safety Officer with an industrial hygiene or safety professional background that help them be successful in this role. In order to work together effectively, it is important that anyone responding to an emergency be familiar with all standards and protocols.
