FN meaning in Governmental ?

A firefighter is a rescuer extensively trained in firefighting, primarily to extinguish hazardous fires that threaten life, property, and the environment as well as to rescue people and in some cases or jurisdictions also animals from dangerous situations. Male firefighters are sometimes referred to as fireman (and, less commonly, a female firefighter as firewoman).

The fire service, also known in some countries as the fire brigade or fire department, is one of the three main emergency services. From urban areas to aboard ships, firefighters have become ubiquitous around the world.

The skills required for safe operations are regularly practised during training evaluations throughout a firefighter's career. Initial firefighting skills are normally taught through local, regional or state-approved fire academies or training courses. Depending on the requirements of a department, additional skills and certifications such as technical rescue and pre-hospital medicine may also be acquired at this time.

Firefighters work closely with other emergency response agencies such as the police and emergency medical service. A firefighter's role may overlap with both. Fire investigators or fire marshals investigate the cause of a fire. If the fire was caused by arson or negligence, their work will overlap with law enforcement. Firefighters also frequently provide some degree of emergency medical service, including certifying and working as full-time paramedics from engine, truck, and rescue companies in some systems to initiate advanced life support until ambulance transport arrives.
