Is carbon dioxide a toxic gas? Does its alarm belong to the category of toxic gas alarms?
Thread Content
I would like to ask the experts: Carbon dioxide is a simple asphyxiant gas; does it fall under the category of toxic gases? When setting up the alarm, should it be configured based on the radius of the toxic gas? Are there any specific standards regarding the design of detection and alarm systems for pure asphyxiant gases? Is there any regulation that specifies that purely asphyxiating gases are considered toxic gases?
It definitely isn’t a toxic gas alarm; there’s no such standard
I have a question: I need to trigger an alarm for carbon dioxide, but I’m not sure which button to use. Online, I found that it belongs to the category of asphyxiating gases, yet there are no relevant regulations specifying how to handle this situation. Using the button designated for flammable gases isn’t appropriate, and neither is using one designated for toxic gases~~~
There is carbon dioxide in the air – what’s the use of an alarm? **The specification refers to the amount that causes harm; this should be some requirement related to a specific manufacturing process, right? Determined based on operating conditions……
Carbon dioxide does not need to be monitored; an oxygen level detector installed on site is sufficient
You should be clear about why your position requires the detection of this gas. For example, in my role involving cryogenic air separation units, the carbon dioxide concentration in the surrounding atmosphere may be high; in such cases, I can set up the detection at the inlet of the air compressor. If you are in a design firm and want to install it in the office, unless your office building is in that area.
There are regulations regarding toxic gases, and these regulations cite the names of toxic chemicals listed by the Ministry of Health.
The carbon dioxide environment can measure oxygen content.
Online carbon dioxide monitoring is carried out when the carbon dioxide level in the atmospheric environment at the air separation unit’s inlet is high, in order to adjust the operation of the air separation unit and prevent carbon dioxide from freezing and blocking the pipes in the cryogenic tank. In enclosed environments that are not classified as toxic or hazardous areas, only oxygen level detection is required.
