ABOUT GAS
Gas Hazards - Oxygen
Properties:
Odourless, colourless and tasteless gas. Can be displaced or diluted by other gases including carbon dioxide and nitrogen as well as other inserting or toxic gases.
Description:
Oxygen content in normal atmosphere is approx 20.9% by volume, the balance is primarily nitrogen.
Health Hazards:
At 15 -19% oxygen impaired coordination and a decreased ability to work strenuously. At 10 -14% respiratory problems. Few recover after more than 5 mins in less then 8% oxygen
Exposure Limits:
Deficiency: 18%
Enrichment: 23%
Typical Applications:
Deficiency: areas subject to oxidation combustion, bacterial growth, oxygen displacement by other gas or purge gases.
