Regarding the building height of the on-site cabinet room

This standard refers to the building height of the on-site cabinet room, aiming to ensure the safe and reliable operation of the equipment within the cabinet room as well as to enhance the safety of personnel on site. Cabinet rooms should not exceed two floors for the following main reasons: 1. Equipment layout and maintenance: There are numerous electrical and control devices in cabinet rooms, which require proper layout and maintenance. If the height of the cabinet room is too high, it increases the difficulty of equipment maintenance, and there are also risks associated with moving the equipment as well as for the workers performing the tasks. 2. Fire fighting and rescue: If the height of the cabinet room is too great, it will pose significant difficulties for fire fighting and rescue operations. When the fire spreads, firefighters may not be able to enter the cabinet room in time to extinguish the fire and carry out rescue operations, thereby increasing the risk of accidents. 3. Seismic resistance: The higher the height of the cabinet room, the weaker its seismic resistance, which increases the risk of damage to the cabinet room due to natural disasters such as earthquakes. If the height of your cabinet room building exceeds two floors, you can take the following measures: 1. Improve the building’s blast resistance to enhance the safety of the personnel on site. 2. Install robust firewalls and fire doors to enhance the fire protection capabilities of the cabinet room. 3. Design a reasonable fire extinguishing system, and conduct timely and regular inspections and upgrades. It should be noted, however, that the above measures only apply to the renovation of cabinet rooms in existing facilities; the requirement that new cabinet room buildings not exceed a height of two floors must still be followed. -

When did this standard come into effect?

SH3006-2012 is a standard within the \"Safety Regulations for Industrial Enterprises – Safety Regulations for the Installation and Maintenance of Mechanical and Electrical Equipment,\" which was issued in 2012. This standard specifies safety requirements such as the building height of on-site cabinet rooms, with the aim of ensuring the safe and reliable operation of equipment within those cabinets and enhancing the safety of personnel on site. This standard has now become one of the important standards for the design, construction, and use of cabinet rooms in the chemical industry. -

For the plant that came online in 2011, the cabinet areas indeed have two floors: the lower floor houses the cabinet rooms and air conditioning units, while the second floor contains the outdoor operation room and locker rooms

If your equipment cabinet room is already in use and is a two-story building, then to ensure the safety of the equipment and personnel on site, you may consider taking the following measures: 1. Modify the cabinet room to be fire- and explosion-resistant in order to enhance safety at the site. 2. Assess the seismic resistance of the cabinet room, and carry out necessary reinforcement and modifications to improve the safety and reliability of the on-site equipment. 3. Reasonably optimize the design of ventilation, drainage, etc. in the cabinet room to improve the quality of the working environment there. 4. Establish a comprehensive safety management system to ensure the safety of personnel and equipment on site. It should be noted that during operation, the equipment and systems in the cabinet room need to be regularly inspected and maintained, so as to promptly eliminate any potential safety hazards and ensure the safe and stable operation of the site. -

SH3006-2012: “The height of the on-site cabinet room for explosion-proof structures should be one floor, and should not exceed two floors.” It refers to the building height ； Earlier versions of SH 3006 did not specify any requirements regarding building height; this requirement was added in the 2012 version, primarily to meet the needs of enhancing a building’s blast resistance. Although there are separate specifications for the blast resistance of control rooms (SH/T 3160 Specification for Blast Resistance Design of Petrochemical Control Rooms), increasing the building height leads to a sharp rise in blast resistance costs, making it difficult to control quality; this is likely the main reason why a maximum of two floors is specified. .

There are also requirements in HG20508. It should not exceed two layers; two layers should be sufficient as well
