概括
自行车头盔在电动滑板车碰撞中显著减少头部受伤,降低加速和头部受伤标准 (HIC). 然而,严重的头部和部伤害风险仍然存在,这凸显了改善安全措施的必要性.
科学领域:
- 生物力学 生物力学
- 伤害预防 预防伤害
- 运输安全运输安全
背景情况:
- 电动滑板车的使用正在增加,导致头部和部受伤的增加.
- 关于电动滑板车撞击冲击和头盔有效性的实验数据有限.
研究的目的:
- 在模拟的电动滑板车中实验评估自行车头盔的性能.
- 评估头部动力学,撞击条件和带头盔或不带头盔的受伤风险.
主要方法:

Personal Protective Equipment
Personal protective equipment (PPE) is unique clothing or equipment worn by an employee to minimize or prevent exposure to infectious agents. PPE creates a barrier between the employee and the infectious materials. PPE must be readily available in the patient care area. PPE includes gloves, gowns and aprons, masks and respirators, goggles, face shields, shoes, and headcovers:
Survey Safety
Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...
