危險化學品兼具有毒、有害、易燃、易爆屬性，存儲環節的一絲疏漏，都可能引發致命安全事故。天津港“8·12”特別重大火災爆炸事故，就因?；反鎯`規造成165人遇難、直接經濟損失68.66億元，慘痛教訓警示我們：危化品庫的規劃設計與儲存管理，必須嚴守規范、零容忍。今天就結合GB 55037-2022《建筑防火通用規范》，搭配實打實的數據，跟大伙嘮透?；穾鞂訑导捌矫娌贾玫暮诵囊?，筑牢安全防線。

　　Dangerous chemicals have toxic, harmful, flammable, and explosive properties, and even a slight negligence in storage can lead to fatal safety accidents. The "8.12" major fire and explosion accident in Tianjin Port resulted in 165 deaths and direct economic losses of 6.866 billion yuan due to illegal storage of hazardous chemicals. This painful lesson reminds us that the planning, design, and storage management of hazardous chemical warehouses must strictly adhere to regulations and have zero tolerance. Today, based on GB 55037-2022 "General Code for Building Fire Protection" and solid data, we will discuss with everyone the core requirements for the number of floors and layout of hazardous chemical warehouses, and build a strong safety defense line.

　　先明確核心底線：?；穾斓膶訑倒芸厥堑谝坏腊踩P卡，絕非可靈活調整的細節。根據GB 55037-2022第4.2.5條規定，甲、乙類倉庫及儲存丙類可燃液體的倉庫，必須采用單多層建筑，嚴禁建設高層建筑——這類?；坊馂穆铀俣瓤?、爆炸威力大，高層建筑疏散難度增加80%，且救援作業受限，一旦發生事故，傷亡損失會翻倍。數據顯示，違規建設高層危化品庫的事故發生率，是單多層倉庫的3.2倍，全程嚴守層數要求是安全前提。

　　First, clarify the core bottom line: the level control of hazardous chemical warehouses is the first safety checkpoint, and it is not a detail that can be flexibly adjusted. According to Article 4.2.5 of GB 55037-2022, Class A and Class B warehouses, as well as warehouses storing Class C flammable liquids, must use single story and multi story buildings, and it is strictly prohibited to construct high-rise buildings - these hazardous chemicals have a fast spread of fire, high explosive power, an 80% increase in evacuation difficulty in high-rise buildings, and limited rescue operations. Once an accident occurs, the casualties and losses will double. The data shows that the accident rate of illegally constructing high-rise hazardous chemical warehouses is 3.2 times higher than that of single and multi story warehouses, and strictly adhering to the layer requirements throughout the entire process is a safety prerequisite.

　　防火分區與防火墻分隔，是遏制事故擴散的關鍵，不同類別?；返姆指粢蟛町愶@著。規范第4.2.6條明確，倉庫內防火分區或庫房之間，必須用防火墻分隔；其中甲、乙類倉庫的防火分區的防火墻，需做到無任何開口，杜絕火焰、有毒氣體通過縫隙蔓延。實操中，甲類危化品單個防火分區最大允許建筑面積不超過2500㎡，設置自動滅火系統可翻倍，而乙類倉庫單個防火分區最大面積可達5000㎡，違規擴大分區會讓火災蔓延速度提升4倍以上。

　　The separation between fire compartments and firewalls is the key to curbing the spread of accidents, and the separation requirements for different categories of hazardous chemicals vary significantly. According to Article 4.2.6 of the regulations, fire compartments within warehouses or between warehouses must be separated by firewalls; The firewalls in the fire compartments of Class A and Class B warehouses must have no openings to prevent flames and toxic gases from spreading through gaps. In practice, the maximum allowable building area for a single fire protection zone for Class A hazardous chemicals does not exceed 2500 square meters, and the installation of an automatic fire extinguishing system can double it. However, the maximum area for a single fire protection zone for Class B warehouses can reach 5000 square meters. Unauthorized expansion of zones can increase the spread of fire by more than four times.

　　輔助用房的布置規范，更是藏著不可忽視的安全細節，三類倉庫的要求各有側重。根據規范第4.2.7條，所有?；穫}庫內，都嚴禁設置員工宿舍及與庫房運行管理無直接關聯的用房，這類違規布置在中小?；菲髽I中占比約12%，是引發人員傷亡的重要誘因——一旦發生泄漏、爆炸，宿舍及無關用房人員疏散不及時，傷亡概率會大幅提升。

　　The layout standards of auxiliary rooms also contain important safety details that cannot be ignored, and the requirements for the three types of warehouses have their own emphasis. According to Article 4.2.7 of the regulations, it is strictly prohibited to set up employee dormitories and buildings that are not directly related to warehouse operation and management in all hazardous chemical warehouses. Such illegal arrangements account for about 12% of small and medium-sized hazardous chemical enterprises and are an important cause of casualties. Once a leak or explosion occurs, if personnel in dormitories and unrelated buildings are not evacuated in a timely manner, the probability of casualties will increase significantly.

　　甲、乙類倉庫的管控最為嚴格，不僅嚴禁在庫內設置辦公室、休息室等輔助用房，更不允許與這類用房及其他場所貼鄰。這類?；范酁橐兹家妆?、劇毒品類，如氰化鈉、硝酸銨等，哪怕是微小的火花或人員活動，都可能引發事故，數據顯示，甲、乙類倉庫違規設置辦公室的事故，死亡率高達75%以上，全程零違規布置是底線中的底線。

　　The control of Class A and Class B warehouses is the strictest, and it is not only strictly prohibited to set up auxiliary rooms such as offices and rest rooms inside the warehouse, but also not allowed to be adjacent to such rooms and other places. These types of hazardous chemicals are mostly flammable, explosive, and highly toxic, such as sodium cyanide, ammonium nitrate, etc. Even small sparks or human activities can cause accidents. Data shows that accidents caused by illegal office settings in Class A and B warehouses have a mortality rate of over 75%, and zero violations throughout the entire process are the bottom line.

　　丙、丁類倉庫雖可設置辦公室、休息室等輔助用房，但需滿足嚴苛的分隔要求，缺一不可。必須采用耐火極限不低于2小時的防火隔墻、耐火極限不低于1小時的樓板，搭配防火門、防火窗實現全封閉分隔，同時輔助用房需設置獨立安全出口，嚴禁與庫房共用疏散通道。實測顯示，未達標分隔的丙類倉庫，火災時輔助用房被引燃的概率達90%，規范分隔可將這一概率降至5%以下。

　　Although Class C and Class D warehouses can be equipped with auxiliary rooms such as offices and rest rooms, they must meet strict separation requirements and are indispensable. Fire resistant partition walls with a fire resistance limit of not less than 2 hours and floor slabs with a fire resistance limit of not less than 1 hour must be used to achieve fully enclosed separation with fire doors and windows. At the same time, independent safety exits must be set up in auxiliary rooms, and it is strictly prohibited to share evacuation routes with warehouses. Actual testing shows that in Class C warehouses that do not meet the standard for separation, the probability of auxiliary rooms being ignited during a fire is 90%. Standardized separation can reduce this probability to below 5%.

　　除了核心規范，還有幾點細節需嚴守，進一步規避安全隱患。?；穾煨柽x址在城鎮規劃區邊緣或相對獨立的安全地帶，與居民區、公共設施的安全距離不小于50米，甲類?；穾煨钄U大至100米以上；倉庫周邊需設置可供消防車通行的道路，寬度不小于4米，保障救援車輛快速抵達；同時嚴禁在庫內堆放無關物品，違規堆放會讓火災撲救難度增加60%，還可能引發二次危險。

　　In addition to the core specifications, there are several details that need to be strictly observed to further avoid security risks. The hazardous chemical warehouse should be located on the edge of the urban planning area or in a relatively independent safe zone, with a safe distance of not less than 50 meters from residential areas and public facilities. The Class A hazardous chemical warehouse should be expanded to over 100 meters; A road with a width of no less than 4 meters should be set up around the warehouse for fire trucks to pass through, ensuring that rescue vehicles can arrive quickly; At the same time, it is strictly prohibited to stack unrelated items in the warehouse. Unauthorized stacking can increase the difficulty of firefighting by 60% and may also cause secondary hazards.

　　從行業現狀來看，違規存儲仍是主要安全隱患，約80%的?；反鎯κ鹿?，都源于未嚴格遵守GB 55037-2022規范，要么違規建設高層倉庫，要么防火墻存在開口，要么輔助用房布置不合規。這些看似微小的違規，一旦疊加?；返母呶傩?，就可能釀成無法挽回的悲劇，不僅造成巨額經濟損失，還會觸犯法律，相關責任人需承擔刑事責任。

　　From the current situation of the industry, illegal storage is still the main security hazard. About 80% of hazardous chemical storage accidents stem from failure to strictly comply with the GB 55037-2022 standard, either by illegally constructing high-rise warehouses, having openings in firewalls, or non compliant layout of auxiliary buildings. These seemingly minor violations, once combined with the high-risk attributes of hazardous chemicals, may lead to irreparable tragedies, causing not only huge economic losses but also violating the law, and the relevant responsible persons shall bear criminal responsibility.

　　總結來說，?；穾斓膶訑蹬c平面布置，每一項規范都源于慘痛教訓，每一個數據都彰顯安全底線。嚴守單多層建設要求、規范防火墻分隔、杜絕違規設置輔助用房，既是落實GB 55037-2022規范的硬性要求，也是防范68億+經濟損失、守護人員安全的關鍵。唯有全程零違規、細節不松懈，才能讓?；反鎯h離隱患，兼顧生產安全與公共安全，筑牢?；饭芸氐牡谝坏婪谰€。

　　In summary, the number of floors and layout of hazardous chemical warehouses, as well as every standard, are derived from painful lessons, and every data reflects the safety bottom line. Strictly adhering to the requirements of single and multi story construction, standardizing firewall separation, and eliminating the illegal setting of auxiliary rooms are not only the mandatory requirements for implementing the GB 55037-2022 standard, but also the key to preventing over 6.8 billion economic losses and safeguarding personnel safety. Only with zero violations throughout the entire process and meticulous attention to detail can hazardous chemical storage be kept away from hidden dangers, balancing production safety and public safety, and building the first line of defense for hazardous chemical control.
