Would anyone be able to help me with the following question / calculation:-
How to calculate the air requirements for a person entering into a confined space, i.e a tank

I an, I am not quite sure what you're after. It's always better to have some air! Sorry being a bit flippant. If you could give us an idea of the sort of tank, location etc and the sort of work we might be able to give you some better idea. Alternatively see the ACoP L101 on confined spaces or drop me a pm.

As above, not sure what you are asking. However, the following parameters may be of some assistance: 19% low oxygen level; 21% normal air oxygen level; 23% oxygen enriched atmosphere.

Perhaps you are asking about possible air changes or flow through and area to maintian this level.?
What work are you conducting inside the vessel

Now I have got myself back to my desk I ca also offer the following
23.5% Gas monitor will alarm to warn of oxygen enrichment (this is ther GMI Visa monitor).
23% Oxygen enriched atmosphere - danger of fire or explosion.
21% Normal air oxygen level.
19.5% Gas monitor alarm level 1
19% Minimum ‘safe entry level’.
17% Possible euphoria, lethargy.
15% Disturbed respiration, increased lethargy, fatigue, and sickness.
13% Possible loss of bladder and/or bowel control.
11% Increased respiration, headache, legs collapse.
9% Major organs ‘close down’ to conserve oxygen. Rapid increase in breathing rate - hyperventilation, unconsciousness.
Less than 6% Respiration and heart stops, coma, convulsions, brain damage. Death in minutes.
