Firefighter Uniforms Must:Firefighter Uniforms Must:• Be functional• Allow tasks to be performed

– Fire– Chemical/biological agents

• Protect against toxic substance exposure• Allow quick and efficient movements

Ergonomic Test ProtocolErgonomic Test Protocol• Assessed

– Functional characteristics

– Fit– Comfort

• Divisions– Anthropometric– Range of motion– Generic dynamics– Job-specific

dynamics– Manual tasks– Donning

Experimental FabricsExperimental Fabrics• 100% cotton needlepunched nonwoven

with carbon filler• 100% cotton print cloth treated with

epoxy bis-phosphonate monomer, cyanoguanidine and citric acid

• Twaron woven fabric with ripstop weave• Nomex III A moisture barrier• Silicone rubber sheeting

Construction ParametersConstruction Parameters• Flat-pattern methodology• Juki industrial sewing machine

– 12 stitches/inch• Cotton wrapped polyester thread• Machine quilting

– Needlepunched nonwoven and print cloth– For thermal barrier

ConclusionsConclusions• Lightweight, body-hugging protective

clothing can be constructed giving maximum protection to the wearer.

• Closure issue addressed for ease of donning and doffing the uniform.

• Better mobility due to breathing apparatus being located in an enclosed back pouch.

• Radio easily accessed on the jacket sleeve.
