May overflow vents and drain valves be installed on storage tanks for Class A flammable liquids? ? Urgent! Urgent! Urgent! ! ! What safety hazards or additional leakage points could arise? ? ?
It’s okay, there’s no rule saying it can’t be set up; we use it a lot in actual production
Then if the overflow port is connected to the atmosphere, wouldn’t the liquid evaporate very rapidly? Also, if a breather valve is installed, then there shouldn’t be a spill port, right? ?
The overflow port does not have to be in communication with the atmosphere...
There will definitely be some evaporation in a direct-through system; devices such as water seals can be installed. An overflow outlet is possible, and it’s essential to have a tank that can be used in emergency situations
