The team that developed this bibliography first searched for occupational health and safety resources specific to law enforcement. Once those resources were collected, the team expanded its search to include other resources that could be relevant to the health of public safety employees. Resources were grouped into categories that aligned with those used by the Centers for Disease Control and Prevention's National Institute on Occupational Safety and Health (NIOSH). The four topic areas of the bibliography are 1) Diseases, such as influenza, heart disease, and mental illness; 2) Hazards, such as weather and other environmental conditions with health risks; 3) Safety, which pertains to injury, protective gear, and resources for law enforcement officers performing various types of duties; and 4) Emergency Preparedness, which pertains to preparedness for any event that has potential dangers for many people or a community, requiring an immediate response. When possible, the bibliography groups resources within each category by type, i.e., journal articles, signs and posters, videos and podcasts, and links to websites.
