Determination of gas alarm level
Thread Content
I have a question: What determines the alarm levels for toxic gases and flammable gases? What actions are taken after reporting the incident? Thank you
Toxic gases are generally warned at a concentration level of 20% that can cause harm to the human body, while flammable gases are generally warned at a concentration level of 20% corresponding to their lower explosive limit
Are there no distinctions between level 1 alarms and level 2 alarms?
You can set it yourself; generally, there are low and high alarm settings. Please check the instructions for details. If you have any problems, feel free to ask me and I’ll show you how to resolve them
It can be set according to the on-site conditions. For combustible gases, a warning is issued at 20% of the lower explosive limit concentration, while emergency evacuation is carried out at 25%. These should be determined during risk assessment and implemented during commissioning.
