Physical employment standard for Canadian wildland fire fighters; identifying and characterising critical initial attack response tasks
2018
AbstractPhysical employment standards evaluate whether a worker possesses the physical abilities to safely and efficiently perform all critical on-the-job tasks. Initial Attack (IA) wildland fire fighters (WFF) must perform such critical tasks in all terrains. Following a physical demands analysis, IA WFF (n = 946 out of a possible 965) from all fire jurisdictions ranked the most demanding tasks and identified mountains, muskeg and rolling hills as the most challenging terrains. Experimental trials found the oxygen cost (mean ± SD O2 mL·kg–1·min–1) while performing the hose pack back carry to be 40 ± 7 in steep mountains, 34 ± 5 in muskeg and 34 ± 2 in rolling hills (n = 168). Back-carrying and hand-carrying a 28.5 kg pump, back-carrying a 25 kg hose pack and advancing charged hose were the most demanding tasks. Performing the same emergency IA WFF tasks was significantly more demanding in mountains (p ≤ 0.05), and these higher demands must be taken into account when developing a physical employment stand...
