Regarding the issue of no doors leading directly outside should be provided in cabinet rooms
Thread Content
There is a provision in the design specifications for chemical engineering control rooms stating that there should be no doors leading directly outside in the cabinet room. Does this requirement apply only to control rooms that have cabinet rooms, or does it apply to all cabinet rooms? For example, does a cabinet room that contains cabinets only need to comply with this rule as well? I understand this refers only to the area between the control room and the cabinet rooms, where the doors of those cabinet rooms can only open toward the operation room to facilitate personnel management – is that correct?
Your understanding is correct; this requirement in the design specifications for chemical process control rooms applies only to those control rooms that have cabinet areas, and not to all cabinet areas. This requirement is mainly aimed at facilitating personnel management and ensuring safety, by preventing doors that lead directly from the cabinet room to the outside from being opened by unauthorized persons, which could otherwise lead to equipment damage or safety incidents. Therefore, this requirement may not apply to cabinet rooms where only cabinets are placed on site, but an evaluation and decision need to be made based on the specific circumstances. .
