I’m completely confused about the ventilation requirements for Class A warehouses.
Thread Content
Assume a Class A warehouse: First, it was generally required to have 6 air changes under normal conditions, and 12 air changes in the event of an accident. The fan draws in air from outside the warehouse while expelling the air inside, thereby maintaining pressure balance and carrying out ventilation. Article 2: It is now required that the exhaust gases emitted without proper control from Class A warehouses must be collected (it’s a requirement related to environmental protection, right?) ), then the exhaust gases are led to the exhaust treatment device through pipes via negative-pressure collection devices such as suction hoods. Combining the first and second points, Class A warehouses must be airtight except at the fans. Under normal conditions, the fans draw in air from outside the warehouse and exhaust it through negative pressure collection devices such as suction hoods; exhaust cannot occur from other locations (otherwise, the exhaust gas would still be released outside, rendering the installation pointless!) ), is my understanding correct?
I’ve encountered this problem as well; environmental regulations require that the air from normal mechanical ventilation be collected and treated 6 times, and this is indeed difficult to implement. . . . .
Collecting unorganized emissions in accident conditions is a challenging issue
The key is the value and significance of recovering unorganized emissions in accident situations; personally, I don’t think it holds much significance
Uncontrolled emission of gases in accident conditions; collection of emitted gases under normal operating conditions
Personally, I think the collection and handling procedures in the event of an accident are also reasonable. Now even those with normal mechanical ventilation need to have their waste collected and processed – that’s completely absurd. I’m completely confused now; I don’t know what to do with the warehouse. Treatment should be carried out if it exceeds a certain concentration threshold; otherwise, no collection or treatment is necessary.
