Firefighting is considered one of the most dangerous professions due to the extreme conditions and hazards that firefighters face. They must use personal protective clothing (PPC) and equipment (PPE) for safety. Despite advancements in protective gear, especially for thermal hazards, the increased weight and bulk have compromised firefighters' mobility and comfort, exacerbating the risk of overexertion, stress, and injury. Studies have identified issues in PPC design that affect mobility, but there has been a lack of research specifically targeting the user needs of U.S. structural firefighters to improve ergonomic mobility.
On November 16, 2023, Emergency Management Science and Technology published a research article entitled by “Structural firefighter personal protective clothing user needs in the US: a mobility perspective”. This paper investigates the ergonomic mobility of structural firefighting PPC in the U.S., aiming to enhance design and reduce injury rates, ultimately benefiting PPC designers, product developers, and manufacturers.
A Qualtrics survey distributed across the U.S. was used to assess the perceptions structural firefighters regarding the mobility of their turnout suits. Out of 420 completed questionnaires showed that the majority of respondents were male, full-time firefighters with extensive experience, predominantly serving in the Southeast. While 78.1% of participants believed that their turnout suit fit properly, some concerns were raised about general fit issues, bulkiness, and restricted mobility, particularly in the crotch and shoulder areas. The evaluation of mobility and range of motion revealed that 64% of participants felt that their movement was restricted by their PPE, specifically in the crotch and shoulder areas. The study found a significant correlation between proper fit and mobility, with significant dissatisfaction in areas like the crotch, waist, and shoulders when performing actions like bending, kneeling, and overhead reaching. Participants have expressed a desire for design improvements such as lighter weight gear, increased mobility, and improved comfort features like ventilation.
The study highlighted the necessity for better fitting gear that is tailored to individual firefighters measurements, improves mobility, and reduces discomfort and injury risks. The study concludes with recommendations for further analysis of fit and mobility issues by PPE manufacturer and model, in-depth insights from focus groups, and the development of prototype turnout suits with improved mobility and comfort features guided by firefighter feedback and ISO/TS 20141 PPE compatibility testing guidelines.
