be completely isolated from the supply gas. If the
air or nitrogen break-in gas will adversely affect the
downstream system, it too must be isolated.
Since all industrial gases are dangerous to human
life, it must be ensured that there are no leaks in the
system that would compromise the safety of personnel
or property.
Leak detection may be accomplished with a ‘bubble
test’ or an electronic sniffer that determines the amount
of the gas in the surrounding air.
Any leaks that are found must be fi xed at once, before
standard operation of the compressor is resumed.
