Core Viewpoint - The article highlights the potential fire hazards posed by glass products, such as empty bottles and mirrors, when exposed to sunlight during the summer months, emphasizing the need for caution in their storage and handling [3][9][17]. 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].

Group 1 - High temperatures in closed car spaces can exceed 80℃, leading to potential explosions and fires from common items like lighters, perfumes, and power banks [1][5] - A simulation by firefighters showed that lighters can explode within 2 minutes at high temperatures due to the expansion of liquid butane [4][5] - Perfume bottles can eject their nozzles after 20 minutes in high heat, as alcohol inside vaporizes and increases pressure [4][6] Group 2 - Items like sunscreen and aerosol sprays can also explode in high temperatures due to increased internal pressure [6] - A magnifying glass can ignite paper within 40 minutes by focusing sunlight, similar to how other round objects can act as lenses [8] - Power banks can reach temperatures of 137℃ after 50 minutes in a hot car, posing risks of swelling and potential fires, especially if they contain substandard batteries [11] Group 3 - Cooling sprays can cause explosive reactions if used improperly near open flames, as demonstrated in a test where a fire ignited after spraying the product in a closed car [13] - Firefighters advise against leaving items like lighters, perfumes, and power banks in cars during summer to prevent accidents [13]

Core Points - The article highlights the risk of fire caused by glass objects under sunlight, comparing them to "small grenades" due to their potential to ignite surrounding materials [1][4] - A recent incident in Beijing's Huairou district involved a storage compartment catching fire due to improperly stored glass and paper materials, demonstrating the dangers of mixed storage [3][4] - The phenomenon is explained through the lens of the magnifying effect, where sunlight can be focused by glass objects, leading to ignition of flammable materials [6][11] Summary by Sections - **Incident Description** - A fire occurred on June 4 at a street shop's storage compartment, which was quickly addressed by firefighters [1][2] - The compartment contained only cardboard and miscellaneous items, with no active production or electrical wiring present [3] - **Cause of Fire** - The investigation revealed that the storage was overcrowded with mixed items, including empty glass bottles and paper products, which contributed to the fire risk [3][4] - Sunlight entering through gaps in the locked compartment door focused through glass items, igniting nearby combustible materials [4][6] - **Similar Cases** - Other incidents were cited, such as a fire caused by a double-sided mirror reflecting sunlight onto a table, and another involving crystal balls igniting cardboard in a backyard [6][9][7] - **Fire Prevention Tips** - Recommendations include avoiding placing glass objects in direct sunlight and keeping them away from flammable materials [13] - Emphasis on educating children about the dangers of using magnifying glasses and similar items [13]

Core Viewpoint - The release of ten group standards for trendy toy derivative products marks a significant milestone in China's trendy toy industry, transitioning from "wild growth" to a new phase driven by standardization for high-quality development [1][3]. Group 1: Industry Standards - The newly established group standards focus on two innovative dimensions: the first specialized standards for domestic two-dimensional derivative products and regulations for popular trendy toy derivatives such as phone cases, headphone charms, trendy clothing, crystal balls, aromatherapy, and plush products [3]. - The standards respond to industry innovation needs and align with international consumer safety requirements, facilitating a shift from "traffic-driven" to "value-driven" development [3][4]. Group 2: Industry Governance - The introduction of these standards fills a gap in systematic industry regulations, providing authoritative technical guidance for design, production, quality testing, and market circulation [3]. - The standards signify a deep advancement in the industry's governance system from "policy guidance" to "standard leadership," aiming for breakthroughs in quality safety, innovative design, green environmental protection, and international alignment [3][8]. Group 3: Environmental and Quality Control - The Chief Quality Officer of Pop Mart International Group highlighted that environmental compliance requirements, while seemingly increasing costs, actually guide the industry away from vicious low-price competition towards sustainable development based on quality [4]. - The standards on packaging environmental protection not only safeguard consumer health and reduce waste but also enhance the international competitiveness of Chinese trendy toy brands, clearing technical barriers for exports to Europe and the U.S. [4]. Group 4: Global Impact - The release of these standards demonstrates China's commitment to building a regulatory framework and provides an innovative and responsible "Chinese solution" for the sustainable development of the global trendy toy industry [8].
