OBJECTIVES
The effect of lockdown periods on the number of residential fires was investigated based on three factors: the weekly change in the number of residential fires, the time of the day of residential fires, and the notional cost associated with residential fires.
STUDY DESIGN
observational study.
METHODS
Analysis from Open Data Source. A new index was introduced and the weekly change during the lockdown periods was investigated to accommodate the seasonal differences in the number of residential fires.
RESULTS
From the index change, the number of residential fires increased at the beginning of each lockdown period. The timing of residential fires shifted during the day.
CONCLUSIONS
These changes were associated with meal preparation or mealtimes. Adjustment to lockdowns as the global pandemic dragged on, such as changes to mealtimes, and getting used to lockdown life, are believed to be responsible for these changes.
目的
基于三个因素对封锁期对住宅火灾数量的影响进行了调查：住宅火灾数量的每周变化、住宅火灾发生的时间以及与住宅火灾相关的名义成本。
研究设计
观察性研究。
方法
来自开放数据源的分析。引入了一个新指数，并对封锁期内的每周变化进行了调查，以适应住宅火灾数量的季节性差异。
结果
从指数变化来看，每次封锁期开始时住宅火灾数量都会增加。住宅火灾发生的时间在白天发生了变化。
结论
这些变化与做饭或用餐时间有关。随着全球疫情的持续，对封锁措施的调整，如用餐时间的改变以及适应封锁生活，被认为是造成这些变化的原因。
