Firefighter Mobility: Are Boots and Gear Putting Lives at Risk?

Firefighters experience mobility challenges primarily due to the bulkiness and restrictive design of their personal protective equipment (PPE). Standard-issue fire boots and self-contained breathing apparatus (SCBA) are the main culprits. The research indicates that the fixed height of fire boots, as mandated by the National Fire Protection Association (NFPA) 1971 standard, restricts lower body movement. This includes restricted ankle movement, reduced knee mobility, and altered gait. Simultaneously, fixed-size SCBA cylinders can impede upper body mobility, especially for shorter firefighters, limiting neck extension and lumbopelvic flexion. These restrictions combine to cause early fatigue, reduced balance, and increased susceptibility to injuries like strains, sprains, and falls. The findings highlight that standard PPE often does not accommodate the wide range of firefighters' body types.

The design of fire boots significantly affects a firefighter's mobility in several ways. The research found that fixed-height boots, dictated by the NFPA 1971 standard, are a key problem. These boots can limit ankle flexion, which is critical for climbing and navigating uneven terrain. They also restrict knee mobility, hindering the ability to squat or crawl. Furthermore, inflexible boots alter natural walking patterns, increasing fatigue and the risk of trips. The study indicates that the single boot height cannot adequately fit the diverse range of firefighters' leg lengths. Shorter firefighters, in particular, may experience limited lower body mobility due to reduced clearance between the knee and the top of the boot, leading to mechanical binding between turnout pants and hindering movement.

The self-contained breathing apparatus (SCBA) can restrict a firefighter's upper body mobility. The study shows that fixed-size SCBA cylinders limit the range of motion in neck extension and lumbopelvic flexion. This is particularly true for shorter firefighters. This restriction can impair a firefighter's ability to look up, reach, and maintain balance during critical situations. The bulk of the SCBA combined with other gear adds to the overall weight and bulkiness, compounding mobility limitations and contributing to fatigue and the risk of injury.

Personalized protective equipment is crucial for firefighter safety because standard-issue gear doesn't cater to the diversity of firefighters' body types. The research highlights that a 'one-size-fits-all' approach with fixed boot heights and SCBA cylinder sizes can hinder mobility and increase injury risk. By offering a wider range of boot heights and SCBA cylinder sizes, manufacturers can significantly improve firefighter mobility. This tailored approach would reduce the risk of injuries like strains, sprains, and falls, enhance overall safety on the fireground and combat early fatigue. The research underscores the need for gear that considers human factors and uses anthropometric data to better protect and empower firefighters.

Ill-fitting gear, particularly fire boots and SCBA, can severely impact a firefighter's ability to perform critical tasks. Restricted ankle movement, reduced knee mobility, and altered gait caused by standard boots can impede climbing, crawling, and walking on uneven terrain. This restricts their ability to navigate confined spaces and treacherous environments effectively. Fixed-size SCBA can limit upper body movement, making it difficult to look up, reach, and maintain balance, thus hindering situational awareness and the ability to react quickly in emergencies. These limitations contribute to early fatigue, increased risk of falls, and slower response times, all of which can jeopardize a firefighter's safety and the success of rescue operations.
