When liquid nitrogen and/or helium are dispensed they release nitrogen and/or helium gas, which is defined as being a simple asphixiant (displaces oxygen). Displacing oxygen creates the potential for an oxygen deficient or hazardous atmosphere, which is an occupational hazard.


5 points you should know about measuring CO2 in HVAC …

Mar 18, 2019· One of the most important standards in relation to HVAC applications is the ASHRAE green building standard, which places strict requirements on CO₂ sensors in terms of accuracy and requires either that they should be capable of measuring outdoor CO₂ concentration or that the concentration should be estimated based on local statistics.


FUMIGATION CO2 Considerations for a controlled atmosphere ...

CO2, like other fumigant gases, works well at higher temperatures. At a grain temperature of 25°C, a successful fumigation with CO2 can be completed in five days and compares well to fumigants, such as phosphine. However, when grain temperature reaches 20°C, 14 days is required, and when the temperature is 10°C, 56 days are required.
