Core Viewpoint - The recent issues surrounding multi-brand power banks, including recalls, removal from e-commerce platforms, and safety concerns regarding lithium battery cells, have sparked significant public discussion about the safety and management of lithium batteries [1][3]. Group 1: Lithium Battery Characteristics - Lithium batteries, including both ternary lithium and lithium iron phosphate batteries, are categorized as chemical batteries composed of positive and negative electrodes, electrolyte, and separator [1]. - The positive electrode materials include lithium cobalt oxide, lithium manganese oxide, nickel cobalt aluminum oxide, ternary materials, and lithium iron phosphate, while lithium serves as the active material in the negative electrode [1][3]. Group 2: Causes of Thermal Runaway - During normal charge and discharge cycles, lithium ions move between the electrodes, but factors such as usage time, charge/discharge cycles, and temperature differences can increase internal resistance [3]. - External factors like overcharging, over-discharging, short circuits, and high temperatures can lead to chemical reactions within the battery, potentially resulting in thermal runaway, where internal heat cannot be dissipated, leading to fire or explosion [3][4]. Group 3: Firefighting Methods for Lithium Battery Fires - Once thermal runaway occurs, high temperatures can decompose the electrolyte, producing flammable gases like hydrogen and methane, which can ignite without oxygen [5]. - Water is considered one of the most effective extinguishing agents for lithium battery fires, as it can absorb heat through evaporation, lowering the battery's temperature and preventing further thermal runaway [9]. - Perfluorohexane is also effective in extinguishing battery fires due to its cooling, oxygen-isolating, and chemical suppression properties, although it is more expensive [11].

Group 1 - The core theme of the recent safety production month activities in Hangzhou is "Everyone Talks Safety, Everyone Knows Emergency" focusing on identifying safety hazards in the community [1] - The Xihu District introduced an "Emergency Ark" equipped with advanced safety technologies, providing a one-stop safety advisory service covering various safety topics [1] - The event showcased innovative emergency rescue technologies, including robotic dogs for forest fire patrol and drones for aerial emergency rescue [1] Group 2 - The Qiantang District organized diverse safety promotion and emergency drill activities, incorporating a "theory + practice + competition" model in their safety classes [2] - Interactive projects included a fire safety knowledge quiz, identifying daily hazards from cartoons, and practical demonstrations of emergency equipment [2] - Emergency drills simulated critical situations such as toxic exposure in confined spaces, forklift accidents, and hazardous material leaks, enhancing participants' emergency response skills [2]

Core Viewpoint - The Jiangsu Provincial Public Security Department has intensified efforts to combat the production and sale of counterfeit and substandard products in the safety production sector, successfully handling over 280 cases and arresting more than 800 suspects since last year [1][2]. Group 1: Actions Taken - Jiangsu police have launched targeted operations against counterfeit and substandard products, dismantling 13 criminal gangs involved in the production and sale of fake fire extinguishers, gas masks, and fire hoses [2]. - The first conviction in the province for producing and selling counterfeit electric bicycles was achieved in Nanjing, serving as a strong deterrent against such crimes [2]. Group 2: Focus Areas - The police identified nine categories of products that pose safety risks, including fire-fighting equipment, gas stoves, auto parts, construction materials, industrial equipment, mobile phone accessories, automotive oils, fireworks, and electric bicycle batteries and chargers [1]. - Collaborative efforts with departments such as construction, market regulation, and fire rescue have been established to conduct special rectification actions in key industries, leading to the investigation of 35 criminal cases and the arrest of 135 individuals [2]. Group 3: Strategic Approach - The Jiangsu police have developed a comprehensive policing process that emphasizes risk detection, precise strikes, and collaborative governance, transitioning from investigation and punishment to prevention and remediation [2]. - The initiative aims to enhance the overall safety level by implementing full-cycle governance strategies [2].

不仅消防箱检查记录卡存在补签的情况,还有超前填写的现象。记者跟随警韵之家北区A12号楼的业主王 先生来到地下车库,在A-355停车位附近的消防箱检查记录卡上发现,填写日期为6月15日。 "问题不止于此,有些消防箱内没有配备消防水带,干粉灭火器也存在问题。"王先生说。在王先生所住的 单元一楼电梯口的消防箱内,摆放着两个落满尘土的干粉灭火器,"我无意间拉开消防箱的门,发现其中一 个干粉灭火器是空瓶,另一个干粉灭火器的维保时间也存在问题"。 "小区物业消防检查记录卡弄虚作假,存在补签、超前填写的情况。"近日,家住济宁警韵之家的壹粉在齐 鲁壹点情报站反映,小区物业在消防器材管理中存在问题。尽管已接到三张消防罚单,其中空瓶灭火器已 经更换,剩余大多数问题物业公司至今未改正。 文/片 丁安顺 济宁报道 超期未报废 消防巡检仍合格 6月13日上午,记者来到警韵之家小区,多位业主向记者反映小区消防器材管理存在问题。 "这是我拍摄的消防检查记录卡的照片,发现物业工作人员存在补签的现象。"壹粉"美少女"说。 干粉灭火器筒体上一张蓝色的灭火器维修铭牌生产日期为2018年5月,维修日期为2024年1月3日。揭开蓝 色铭牌,下面还有一 ...

"不好！二楼发生火灾。大家赶紧用湿毛巾捂住口鼻，弯腰沿着安全通道疏散……"近日，一场消防 演练在鞍山市铁东区台町历史文化街区展开。 小贴士 铁东区园林街道办事处辖区内的台町地区，拥有100余栋建于上世纪二三十年代的老建筑，防火工 作复杂。对此，园林街道通过组织社区工作人员、网格员及志愿者等，定期上门入户对老建筑的防火情 况进行检查，特别是检查建筑内部的入户电线、燃气管路等防火重点部位。 老建筑使用年限长，用电环境较为复杂，因此老建筑在灭火器配备上一般选择干粉灭火器。干粉灭 火器的压力表有3个颜色不同的区域，其中指针处于绿色区域时，表明灭火器可以正常使用；指针处于 红色区域时，表明灭火器压力不足，无法正常使用，需要维护；指针处于黄色区域时，表明灭火器压力 过高，这种情况下虽然灭火器可以喷出干粉，但是存在一定的安全隐患。 "老建筑的用电负荷有限，因此我们在检查过程中，重点关注电器和用电负荷的增加情况，确保用 电负荷始终处于安全范围内。针对台町地区老建筑内老年居民较多、清理杂物不方便的情况，我们及时 联系废旧物品回收人员上门服务，确保杂物及时得到清理。"园林街道办事处主任刘洪业说。 除了日常的消防安全检查，确保灭火 ...
