Ergonomic analysis of forest fire helmet.

The ergonomic design of forest fire helmet is closely related to its safety performance. In order to improve the performance of forest fire helmet, three representative forest fire helmets are evaluated from the shape, material, safety, comfort and other aspects and analyzed according to the firemen’s usage condition. Some suggestions for helmet design, such as using suspension system, installing height adjuster, using adjustable goggles with peripheral knobs and decomposition using helmets, goggles and masks, are proposed, which provide referential technical guidance for the design of forest fire helmets in the future.
