Firefighters work in unpredictable conditions, necessitating the use of personal protective equipment (PPE). However, the additional weight from the PPE and self-contained breathing apparatus (SCBA) alters their centre of mass (COM), restricts movement and limits vision (face mask) contributing to a firefighters' challenge of maintaining balance. Thus, the purpose of this study was to quantify the effects of firefighter PPE on static and dynamic balance. Participants performed two sets of three functional balance tests: (1) Static Single Leg (SSL); (2) Dynamic Single Leg (DSL); (3) Limits of Stability (LOS). The balance tests were performed under one control and three randomised PPE conditions: (1) athletic clothing; (2) turnouts; (3) turnouts + SCBA; (4) turnouts + SCBA + face mask. Our study found turnouts + SCBA both with and without the face mask negatively affected dynamic balance. These findings identify factors in fall-related injuries and strategies to reduce occupational risk. : Slips, trips and falls are the most common cause of injury in firefighters. Our study investigated the effects of firefighter personal protective equipment (PPE) on static and dynamic balance utilising a computerised balance instrument. We found that turnouts with a self-contained breathing apparatus (SCBA) with or without face mask negatively affected balance.
消防员在不可预测的条件下工作,需要使用个人防护设备 (PPE)。然而,PPE 和自给式呼吸器 (SCBA) 的额外重量会改变他们的质心 (COM),限制运动并限制视野(面罩),这给消防员的平衡能力带来了挑战。因此,本研究的目的是量化消防员 PPE 对静态和动态平衡的影响。参与者进行了两组三个功能性平衡测试:(1) 静态单腿 (SSL);(2) 动态单腿 (DSL);(3) 稳定性极限 (LOS)。平衡测试在一个控制和三个随机 PPE 条件下进行:(1) 运动服;(2) 消防服;(3) 消防服+SCBA;(4) 消防服+SCBA+面罩。我们的研究发现,无论是否戴面罩,消防服和 SCBA 都会对动态平衡产生负面影响。这些发现确定了与跌倒相关的伤害因素和降低职业风险的策略。 滑倒、绊倒和跌倒是消防员受伤的最常见原因。我们的研究使用计算机平衡仪调查了消防员个人防护设备 (PPE) 对静态和动态平衡的影响。我们发现,带有自给式呼吸器 (SCBA) 的消防服或带有或不带有面罩都会对平衡产生负面影响。
