Verification of the Effectiveness of a Fire Hose Backpack in Areas Fire Trucks have Difficulty Accessing

The research aims to verify the effectiveness of firefighting hose backpacks through a comparative analysis backpack and conventional in an area difficult access with fire truck. research, which targets 24 firefighters, was conducted as random cross experiment. To this end, firefighters were divided into 2 groups: one group comprised 12 other hoses. purpose test total time required extinguish firefighters’ degree physical tiredness. In number steps, walked 1109.63 steps less than hoses (p = < .001). Furthermore, taken spread out fire, performed on average 674.75 s faster both tasks, respectively. Regarding heart rates lactic acid production, had 23 fewer pulses .002) produced 3.14 mmol/L .049) An additional verification experiment showed that spreading shortened by 81% speed discharge doubled. addition, operating pressure for appropriate water analyzed be 0.5 MPa 100–200 m, 0.8 300 0.95 400–600 m. Therefore, should encouraged use areas truck rapidly reduce tiredness firefighters.
