Apply passive fire protection systems via spray, brush, roll, trowel, or even board. These fireproofing products do not prevent nor suppress fires. Rather, they ensure adequate thermal insulation of structures in the event of a fire, allowing time for the evacuation of people, etc. That is, passive fire protection ensures the structure (floor, beam, column, cross-bracing, etc., usually concrete or steel) will not buckle &/or collapse within a certain period of rated time (e.g., 1 hour) in the event of a fire. Passive Fire Protection systems range from thin filmed organic coatings to thicker cementitious products to mineral or fibre board. Passive Fire Protective systems contrast with Active Fire Protection systems, the latter of which employs an extinguishing media (e.g., sprinkler systems), and are installed by other trades.
