Public Safety Diver
Be careful about legislation!
Public safety diving is the underwater work conducted by law enforcement, fire rescue, and search & rescue/recovery dive teams. Public safety divers differ from recreational, scientific and commercial divers who can generally plan the date, time, and location of a dive, and dive only if the conditions are conducive to the task. Public safety divers respond to emergencies 24 hours a day, 7 days a week, and may be required to dive in the middle of the night, during inclement weather, in zero visibility "black water," or in waters polluted by chemicals and biohazards.
In the USA, many public safety divers are volunteers, but career law enforcement or fire rescue personnel also often take on these additional responsibilities as part of their occupation. Firefighters will find the diving equipment has similarities to the full face masks and breathing apparatus worn in smoke filled environments.
Public safety divers in the USA may fall under state or federal occupational safety and health legislation.
