Detection of toxic gases at the plant boundary
Thread Content
Dear teachers, during the environmental compliance inspection of a certain facility, experts suggested that automatic detectors and alarms for toxic gases should be installed at the boundary of the factory site. How should the installation location of such detectors and alarms be determined? Which specific standard specifies this? I urgently need the guidance of all teachers; thank you!
Refer to the Code for Design of Detection and Alarm Systems for Flammable and Toxic Gases in Petrochemical Industries, GB 50493-2009
Depending on the gas medium being monitored, GB 50493-2009 has relevant regulations
It’s obvious that this expert came up with this idea on a whim; instead of examining your overall layout and the distances required for occupational health protection, they focused their efforts on the alarm devices. You should ask him back, on what standard such a requirement is based? Why is it arranged this way? According to his idea, should we install alarm devices around all our factory sites? Since it is an environmental compliance inspection, it is necessary to consider whether your environmental indicators are monitored in real time, whether the process technologies used meet the required standards, how well these environmental indicators are implemented, whether tests related to these indicators were conducted during the trial operation period, and where the test records can be found. The experts present for on-site inspection each had their own opinion and theory. Back in the day, when some of our company’s facilities were undergoing the three-concurrent acceptance inspections, I questioned those experts, and as a result, many of the subjective issues that should have been raised disappeared.
The skill levels of experts these days vary greatly, which is really troublesome
