Distance between Class A workshops and other Class A workshops
Thread Content
The 15m or 12m fire separation distance specified in Article 4.2.9 of the \"Fire Protection Standards for Engineering Design of Fine Chemical Enterprises\". When equipment is located at the edge of the workshop, the arrangement within the facility also has a significant impact on the fire separation distances specified in the overall layout. In accordance with Note 4 of Article 4.2.9 of the \"Fire Protection Design Standards for Fine Chemical Enterprises,\" the fire separation distance between the liquefied hydrocarbon storage tanks in the workshop’s tank group and other production facilities outside that workshop must meet the requirements outlined in this table. That is, the distance between the liquefied hydrocarbon storage tanks and other production facilities must satisfy both the fire separation requirements specified in Article 4.2.9 for such tanks and those for Class A production facilities, with the larger of these two values being adopted. When there is equipment installed between Class A workshops, is it necessary to adjust the fire separation distance based on the medium used by that equipment?
Yes, adjustments are needed. In accordance with Article 4.2.9 and its explanatory notes of the \"Fire Protection Design Standards for Fine Chemical Enterprise Engineering\", when equipment is installed between two Class A workshops, the following aspects must be considered simultaneously: 1. The fire separation distance between the facilities within each workshop ； 2. Fire separation distances between equipment installed within or at the edge of the workshop (such as liquefied hydrocarbon tanks) and other workshops or facilities ； At this time, the fire separation requirements for these two scenarios should be satisfied simultaneously, and the larger of the two values should be adopted. In other words, if there are equipment between a Class A workshop and another Class A workshop, it is necessary to analyze each of these pieces of equipment in terms of its medium and installation conditions, and ensure that they meet the corresponding fire separation requirements based on their respective media. Only by meeting the above requirements simultaneously can it meet the standards, which means that it may be necessary to adjust the fire separation distances from the existing values (usually by increasing them appropriately). A common practice in practice is to determine it based on the strictest fire separation requirement to ensure safety and compliance. .
Yes, the spacing will be very large this way.
