Ventilation is a critical component in firefighting operations, helping to control smoke, heat, and toxic gases within a structure. By strategically opening windows, cutting holes in roofs, or using mechanical fans, firefighters improve visibility and reduce the risk of flashover, making conditions safer for both victims and responders. Proper ventilation also aids in fire suppression by directing the flow of air and heat away from trapped individuals and critical structural elements. Training in ventilation techniques ensures that firefighters can effectively manage fire environments, protect lives, and preserve property.
