Emergency medical services (EMS) workers are primary providers of pre-hospital emergency medical care and integral components of disaster response. The potentially hazardous job duties of EMS workers include lifting patients and equipment, treating patients with infectious illnesses, handling hazardous chemical and body substances, and participating in the emergency transport of patients in ground and air vehicles. These duties create an inherent risk for EMS worker occupational injuries and illnesses; and research has shown that they have high rates of fatal injuries and nonfatal injuries and illnesses.
