Group 1: Incidents of Fire Caused by Glass Products - On June 4, a storage compartment in Beijing caught fire due to sunlight refracting through empty glass bottles, igniting surrounding flammable materials [3]. - A similar incident occurred in Fujian, where sunlight focused through a double-sided mirror ignited a promotional flyer, leading to a fire that destroyed items in the store [5][6]. - In May of the previous year, a backyard fire in Zhejiang was traced back to 80 crystal balls that reflected sunlight, igniting nearby cardboard boxes [8]. Group 2: Other Fire Hazards in High Temperatures - A fire in a vehicle in Beijing was caused by sunlight heating water bottles placed on top of the truck, which ignited surrounding materials [11]. - The structure of common items like bottled water and reading glasses can act as convex lenses, concentrating sunlight and increasing temperatures, which can lead to fires [13]. - Firefighters conducted experiments showing that items like lighters and spray cans can explode when left in a car under direct sunlight, with significant temperature increases observed [15]. Group 3: Safety Recommendations - It is advised to keep items such as magnifying glasses, bottled water, and other glass products away from direct sunlight and flammable materials [17]. - Specific caution is recommended for items like lighters, power banks, and aerosol sprays, which should not be left in vehicles during hot weather [17].
