It is impossible to become a fire fighter online because of the type of training that fire fighters go through. There are practical skills that can only be imparted in a face-to-face or offline training program.
Fire fighters are specialized professionals who help save lives and property. To gain the skills needed for this career, you need to undergo rigorous training that combine in-class lectures and on-field practical lessons.
Some of the lecture lessons can be delivered online; however, lectures alone do not equip you with requisite skills for a successful fire fighting career. You must complement the lectures with real life practical training. The practical lessons are valuable in exposing you to different scenarios and equipping you with skills that are necessary for the field.
