This study quantified the impact of hood design on firefighters' range of motion, noise production, and hearing. Particulate-blocking hoods reduced rotational range of motion, while thicker hoods decreased hearing ability. Design, rather than the number of layers, affected noise production during head movement.
Firefighter hoods must provide protection from elevated temperatures and products of combustion while simultaneously being comfortable and limiting interference with firefighting movement or completion of fireground activities. This study was to quantify the impact of hood design (traditional knit hood vs. several models of particulate-blocking hoods) on wearability measures such as range of motion, noise production and hearing threshold. Firefighters' perceptions of wearability were also collected. In a controlled laboratory environment, 24 firefighters performed movement and hearing tests. Wearing particulate-blocking hoods resulted in decreased rotational range of motion, and thicker hoods reduced hearing ability. Design, but not necessarily the number of layers, affected noise production by the hood during head movement.Practitioner summary: Particulate-blocking hoods resulted in reduced rotational range of motion relative to the traditional design and the no-hood condition. Hoods with additional layers resulted in decreased hearing ability. Noise production was increased in designs of particulate-blocking hoods with a membrane-based blocking layer independent of the number of layers.
