If your multigas CGI meter shows 0% of LEL, 20.9% O2, and 0ppm CO, what can you conclude?

The readings from the multigas CGI meter indicate a safe environment based on the presented values. With 0% of the Lower Explosive Limit (LEL) for flammable gases, it is clear that there is no presence of combustible gases that could initiate a fire or explosion under the given conditions.

The oxygen level of 20.9% is characteristic of normal atmospheric conditions, as this is the usual concentration of oxygen in the air. Furthermore, the measurement of 0 ppm of carbon monoxide (CO) indicates that there is no detectable concentration of this toxic gas present, which is crucial for safety in an enclosed or confined space.

Taken together, these readings confirm that the environment is free from explosive hazards, toxic gases, and maintains normal oxygen levels, providing a solid conclusion regarding the absence of harmful contaminants.
