Abstract
Firefighter turnout gear and equipment protect the wearer against external hazards but unfortunately restrict mobility The aim of this study was to determine the ease of mobility and comfort while wearing a new prototype firefighter ensemble PE with additional chemical/biological hazard protection compared to a standard ensemble SE by measuring static and dynamic range of motion ROM jobrelated tasks and comfort Eight healthy adults five males three females aged 20–40 years participated in this study The study consisted of two repeated phases separated by five uses of the ensembles Subjects randomly donned either the SE or PE in either dry or wet conditions on separate days In each phase five tests were carried out as follows baseline nonensemble SEdry SEwet PEdry and PEwet There was a significant reduction P 005 of wrist flexion for PEdry condition compared to the same SEdry condition Donning the PE took 80 s longer than the SE in phase 1 this difference disappeared in phase 2 There was a significant decrease P 005 in posttest comfort wearing the PE compared to the SE The data collected in this study suggest that in spite of design features to enhance chemical/biological hazard protection the PE design does not decrease the wearer’s overall functional mobility compared to the SE However subjects seem to be more comfortable wearing the SE compared to the PE These overall findings support the need for a comprehensive ergonomic evaluation of protective clothing systems to ascertain human factors issuesThe findings and conclusions of this manuscript are those of the authors and do not necessarily reflect the views of the National Institute for Occupational Safety and Health Mention of any company name or product does not constitute endorsement by the National Institute for Occupational Safety and HealthWe would like to thank Ms Nicolette Shriver for her technical support during the experimental testing We would also like to thank Mr Edward Sinkule for his helpful suggestions and careful review of this manuscript This study was partially supported by funding from Technical Support Working Group TSWG This research was performed while one of the authors AC held a National Research Council Resident Research Associateship at the National Personal Protective Technology Laboratory NPPTL
