Should a single call valve be added to the exhaust outlet of the vacuum pump?

Dear friends, if the exhaust outlet of the vacuum pump is connected to the exhaust system, is it necessary to add a single exhalation valve with a flame arrester or a flame arrester? Does anyone have any evidence to follow?

According to Sinopec's document Sinopec Safety and Technology No. 33, the air extraction equipment in front of the recycling facility should be equipped with a detonation flame arrester or a detonation flame arrester that has passed the test under working conditions. According to Sinopec's Sinopec Refining and Refining Letter No. 127, a detonation-resistant flame arrester should be installed at the entrance of the exhaust gas treatment device.
So detailed, thank you very much, brother
Regarding the installation location of the flame arrester, should it be close to the heating equipment or far away?
Just be as close as possible and eliminate it from the source. Of course, it also depends on the piping requirements.
