![]() ![]() On many occasions, fire incidents are encountered where pre-planned fire flow information is not available. To determine needed fire flow during pre-planning requires the application of a "fire flow formula" to conditions observed during an inspection of the premises. When pre-planned information is available to the initial incident commander upon arrival at an incident, strategic and tactical decisions can be made more readily and accurately. This can be attained through a deliberate calculation of the occupancy, considering conditions when establishing the needed fire flow. Though minor, they could have been avoided by recognition of the potential seriousness of the situation by the first-arriving units and proper initial placement of apparatus.ĭetermining the amount of water needed to extinguish a fire in a specific building is best accomplished during the pre-planning stage. A brand patrol was dispatched and extinguished numerous fires.Īs the situation stabilized, firefighters were reporting to first-aid stations for treatment of burns sustained in moving the apparatus. The firefighters were now faced with the threat of flying fire brands being carried downwind and starting incipient fires a distance away. Hoselines were placed to knock down the fire spreading to the dwellings. Residents in night clothing were being evacuated under the protection of hoselines. #Fire commander 2 functions level 3 windowsWood moldings on doors and windows of the dwellings now started to ignite. The radiant heat attacked the vinyl siding, melting it. ![]() The intensity of the fire now ignited vehicles parked in the driveways of the dwellings across the street from the fire building. The disruption of moving the apparatus now meant a delay in placing master streams into operation, compounding an already serious situation. A pumper had to be driven away while still connected to a hydrant, tearing the couplings from the hoseline suction. Plastic reflectors were melting and window glass on a tower ladder was cracking due to the intense heat. Flames were being driven by the high winds from the fire building, causing paint to bubble on the apparatus in front of the fire building. This would remove them from the collapse zone and should the fire reach the level anticipated by the chief, it would not be necessary to relocate the apparatus at a later time under potentially dangerous conditions.īefore the apparatus could be moved, however, the intensity of the fire increased tremendously. The next order was to immediately move the apparatus from in front of the fire building to a flanking position. The chief assumed command and requested second and third alarms. This information will impact on the incident in terms of determining needed resources and the implementation of tactical operations. The first-arriving engine officer had ordered a defensive attack and companies were stretching large-diameter hoseline for master-stream operations.Ī problem facing the initial incident commander at a fire scene is how much water will be needed for effective fire control. Units had positioned their apparatus in front of the fire building. The heavy smoke conditions indicated a fire which, though showing little flame at this time, would develop into a serious problem. A strong wind was blowing from the rear of the fire building toward dwellings across from it. ![]() During the initial size-up, the chief recognized that conditions were not favorable. Heavy fire was pushing from a few windows of the one-story factory. ![]()
