|
Advantages of tactical ventilation |
Assist the escape of occupants by stopping the spread of smoke Improve conditions for firefighters and trapped occupants Speed up rescue operations and fire attack by reducing heat smoke Increase safety of a ff- reduce risk of flashover, backdraught and fire gas explosion. Reduce fire spread and property damage by controlling of hot smoke and gases Improve visibility |
