Disk 4 establishes the “mental safe haven” that every firefighter needs if they plan on going into a burning building. The time to learn how to comprise a MAYDAY or suddenly reorientate yourself to your surroundings is not when things have gone bad. Learn how to effectively communicate a MAYDAY while under survival stress in realistic conditions. Discover how you can maintain orientation to the burning building as soon as you exit the apparatus until you safely exit the structure. Also taught are reading couplings, skip breathing (when anxiety creeps up), four ways of getting out of entanglement, low profiling, and the notorious “Naked SCBA” drill. Disk 4 is mandatory for all levels of your department.
