Which element is NOT typically assessed during atmospheric monitoring?

Humidity is not typically assessed during atmospheric monitoring in confined spaces. The primary focus of atmospheric monitoring is to ensure the safety of individuals entering these potentially hazardous environments. This involves measuring key elements such as oxygen content, flammability, and toxicity.

Oxygen content is crucial because a deficiency or excess can pose immediate risks to human health. Flammability assessments are essential to identify the presence of potentially explosive gases or vapors, which can ignite in certain atmospheric conditions. Toxicity measurements help determine if harmful substances are present that could endanger workers.

While humidity can affect comfort levels and the efficiency of certain processes, it does not pose the same immediate physical threats that the other elements do. Therefore, the focus remains on those factors that directly impact safety and health in confined spaces.
