Is a nitrogen protection system necessary when using low-purity alcohol for cleaning during the operation of a centrifuge? What are the criteria for determining whether nitrogen protection is required?

For example, is alcohol with a purity of 30% or 40% necessary?
Alcohol is volatile and can easily form explosive gases in the enclosed environment of a centrifuge; if sparks are generated due to collisions of the rotor inside the centrifuge, the consequences can be very dangerous. Nitrogen protection is required.
Alcohol is volatile and poses a risk; so how is nitrogen protection used?
Before adding alcohol, purge with nitrogen, measure the oxygen content; once it meets the standards, then add it~
