Personal protective equipment DISCUSSION The lack of significant differences among most of the measurements comparing the standard and prototype ensembles supports our hypothesis. A possible reason for this finding is that the standard ensemble served as the basic platform for the prototype. The differences between the standard and prototype ensembles are the attached boot liner-pant leg interface, the sleeve-glove magnetic ring interface, reinforced jacket zipper, facemask-hood seal interface, and the hose attachment connecting the SCBA to the jacket. The boot liner-pant leg interface differences could be accounted for by the attachment of the boot liner to the pant leg which may have limited plantar range of motion. In addition, the donning/doffing procedures were significantly longer because extra features of the prototype ensemble increased the number of actions used for donning and doffing. Firefighter ensembles limit wearer movement to some extent. The data collected in this study suggest that, in spite of design features to enhance chemical/biological hazard protection, the PE design does not adversely affect the wearer’s functional mobility or comfort compared to the SE in most interfaces. However, the new bootpant interface design of the PE, which incorporates an inside boot-sock extension of the pant, may reduce ankle motion and thus might limit the wearer’s ability to reach while standing on the toes. In general, these results were expected, as the PE was developed from the SE platform. Furthermore, the turnout gear interface seals necessary to provide the elevated protection against chemical/biological hazards should not introduce a significant additional ergonomic burden to firefighters.

DISCUSSION<br />
The lack of significant differences among most of the measurements comparing the<br />
standard and prototype ensembles supports our hypothesis. A possible reason for this<br />
finding is that the standard ensemble served as the basic platform for the prototype.<br />
The differences between the standard and prototype ensembles are the attached boot<br />
liner-pant leg interface, the sleeve-glove magnetic ring interface, reinforced jacket<br />
zipper, facemask-hood seal interface, and the hose attachment connecting the SCBA<br />
to the jacket. The boot liner-pant leg interface differences could be accounted for by<br />
the attachment of the boot liner to the pant leg which may have limited plantar range<br />
of motion. In addition, the donning/doffing procedures were significantly longer<br />
because extra features of the prototype ensemble increased the number of actions used<br />
for donning and doffing.<br />
Firefighter ensembles limit wearer movement to some extent. The data collected in<br />
this study suggest that, in spite of design features to enhance chemical/biological<br />
hazard protection, the PE design does not adversely affect the wearer’s functional<br />
mobility or comfort compared to the SE in most interfaces. However, the new bootpant<br />
interface design of the PE, which incorporates an inside boot-sock extension of<br />
the pant, may reduce ankle motion and thus might limit the wearer’s ability to reach<br />
while standing on the toes.<br />
In general, these results were expected, as the PE was developed from the SE<br />
platform. Furthermore, the turnout gear interface seals necessary to provide the<br />
elevated protection against chemical/biological hazards should not introduce a<br />
significant additional ergonomic burden to firefighters.<br />
