During an intervention, positive pressure ventilation to forced evacuation of smoke or gases is used in the fight against fires in enclosed or semi-open volumes. The Drago’s main objective is to disperse and break down, quickly and efficiently, all types of toxic fumes.
With powerful positive pressure ventilation, Drago has a gas and smoke dispersion capacity that is unsurpassable.
Focus 1: Dispersion of toxic vapor cloud during a fire and liquefied gas discharge class C by the use of water spray or water mist.
Tactic 2: Ventilation to bring the concentration of the toxic vapor cloud in the air below the lower explosive limit or reduction of harmful or explosive concentrations of gas, vapor or aerosol in the air.
Tactic 3: Positive pressure ventilation (PPV) by the use of forced air:
Ventilation after extinguishing the fire during the excavation
Ventilation once the fire under control
Ventilation before the extinguishing operations (without the presence of flame)
Tactic 4: Positive pressure ventilation (PPV) by the use of forced air to disperse the smoke and maintain visibility of ground crews.
