7 thoughts on “Natural or Positive Pressure

  1. Looks as if the natural is already venting it well. With todays fires being so filled with unexpected fire loads, postive pressure too early might accelerate the fire more. They might want to be sure all areas where the venting is occurring is fully cleaned out for any emergency bail outs and allow for most vent possible

    • The fire is certainly venting, but not venting well. There is thick black turbulent smoke to the knee level from an opening with hose and firefighters in it. Bad stuff with happen here soon if nothing changes. No technique is 100% applicable to each scene. Know the fundamentals and be flexible enough to adapt the plan to fit the fire in front of you. These are not buzz words. This is modern firefighting.
