I was checking the permissible level for Argon and Nitrogen but I could not find, though I know that these gases could cause asphyxiant if released to a workshop closed room. I would like to know what is the permissible level and what safety measures should I make to ensure no suffocation will occur while working inside the workshop.

Looking at it from the other perspective, air is about 78% nitrogen, 20.9% oxygen, argon 0.93%
So if you arre worried about asphyiants, nitrogen will displace oxygen - once oxygen drops below about 19% would be of concern.

Most gas cylinders contain of order 10 to 15 cubic metres of gas (the contents are often on the label). So you could work out how much they could potentially reduce the oxygen content of your room.
I imagine you have some kind of ventilation as well.
Bear in mind that if the gas is escaping rapidly, there is a volume close to the cylinder that is seriously depleted in oxygen. However, if it is escaping rapidly you can hear it, so it should be obvious.
A slow leak is unlikely to be dangerous as it will be taken care of by ventilation.
