Oxygen Detection

CAS Number: 7782-44-7

Properties

The oxygen (O2) content in air is about 21%, in water 88.8%, and in the human body it is about 65%.

Dangers

Not enough oxygen in the ambient air can be fatal, causing hypoxia (deprivation of an adequate oxygen supply for the body. On the other hand, excessive oxygen in the air poses a fire hazard as it lowers the combustion temperature of flammable materials, and it serves as an accelerant.

Where is it found

Oxygen is the most abundant naturally occurring gas which is discharged into the atmosphere through the process of plant photosynthesis. It is consumed during the respiration process of flora and fauna, photosynthesis in plants, as well as combustion processes. Essentially, oxygen concentrations are measured in working environments to prevent hypoxia incidents; particularly sites where air often stagnates; for instance: manholes, workshop pits, storage tanks, silos, sewer pipes/conduits, warehouses, holds or galleys (on ships), etc. Typically, measurement of oxygen is required to be conducted before the day's work begins and as necessary throughout.
