Oxygen level above 23.5% considered as oxygen enrichment.

What does oxygen deficiency mean?

Oxygen level below 19.5% considered as oxygen deficiency.

What are the hazards of confined space?

Hazards of confined space are:-
Limited entry/exit.

Oxygen deficiency.
Oxygen enrichment.
Toxic gases.

Note: SCBA/SCUBA tank filled with air in Volume.

For 1 min breathing 1.5 cu.ft. air required.
For 30 minutes = 1.5 × 30 = 45 cu ft.
Pressure left in pressure gauge = Volume of air.
100 bar – 15 min
200 bar – 30 min
300 bar – 45 min.
