In order to reduce the probability and severity of escalator-related injuries and enhance the safety of passengers, this study analyzed 950 escalator-related injuries in Guangzhou metro stations to identify the characteristics and the risk factors associated with escalator-related injuries in China. The data extracted from Management Information System of Guangzhou Metro covers the site and time of the accident, age and gender of the victims, escalator condition and injury information. The results from the statistical analysis indicated that the majority of the escalator-related injuries was caused by failing to stand firm (287 cases, 30.2%), passengers carrying out other tasks (214 cases, 22.5%), not holding the handrail (168 cases, 17.7%) and unhealthy passengers (18 cases, 9.3%). Age was associated with all factors except for need for an ambulance and the distribution law of these factors differed with age groups. Elderly passengers (aged 66 years and above) accounted for the highest proportion of all injuries (49.1%), and failing to stand firm (18.63%) was the main cause of escalator-related injuries of elderly passengers. The most common mechanism of injury for all age groups was a fall, accounting for (51.0%) injuries. Proportion of injuries caused by a fall increased with age, whereas injuries attributed to entrapment decreased. Female passengers (65.9%) were more likely to be involved escalator-related injuries than male passengers (34.1%), while male passengers were more likely to have accidents caused by unhealthy physical condition than female passengers. These results based on the analysis of current accident data can be used to help metro operation corporation develop effective injury prevention measures and document the need for continued improvement of escalator safety in metro stations.
为降低自动扶梯相关伤害的发生概率和严重程度，提高乘客安全水平，本研究分析了广州地铁 950 起自动扶梯相关伤害事件，以明确我国自动扶梯相关伤害的特点及其危险因素。该研究从广州地铁管理信息系统中提取事故地点和时间、受害者年龄和性别、自动扶梯状况和伤害信息等数据。统计分析结果表明，大多数自动扶梯相关伤害是由于站立不稳（287 例，30.2%）、乘客执行其他任务（214 例，22.5%）、未扶扶手（168 例，17.7%）和乘客身体不适（18 例，9.3%）引起的。年龄与所有因素均相关，除需要救护车外，这些因素的分布规律随年龄组而异。老年乘客（66 岁及以上）占所有伤害的比例最高（49.1%），站立不稳（18.63%）是老年乘客自动扶梯相关伤害的主要原因。所有年龄组最常见的伤害机制是跌倒，占（51.0%）伤害。随着年龄的增长，跌倒导致的伤害比例增加，而被夹伤导致的伤害比例下降。女性乘客（65.9%）比男性乘客（34.1%）更容易发生自动扶梯相关伤害，而男性乘客因身体不适导致事故的比例高于女性乘客。这些基于当前事故数据分析的结果可用于帮助地铁运营公司制定有效的伤害预防措施，并记录需要持续改进地铁站自动扶梯安全。
