This program has the following objectives: Identify employees and students that are exposed to hazardous levels of airborne contaminants or become involved in tasks that take place in oxygen-deficient ...

It is widely believed that Earth's atmosphere has been rich in oxygen for about 2.5 billion years due to a relatively rapid increase in microorganisms capable of performing photosynthesis.

The sampling should show that: the oxygen content is within safe limits-not to oxygen deficient or oxygen enriched. A hazardous atmosphere (toxic gases, flammable atmosphere) is not present.

This program was developed to promote a safe work environment and to protect the health and safety of CU Boulder employees and students who are potentially exposed to airborne contaminants or may ...
