FOREWORD
1. Explosions are known or suspected co have occurred in high pressure
oxygen and nitrogen gas systems which were not properly maintained. To
ensure safe operation of these systems,
the accumulation of hydrocarbons in
the systems must be eliminated;
subsequently the systems must be cleaned for
oxygen service.
2 This standard provides a procedure for cleaning and testing oxygen,
nitro~en and hydrogen gas pipin,gsystems.
Requirements for cleaning the nitro-
gen system shall be invoked only when the nitrogen is used for purging the oxygen
system and oxygen generator.
3. This standard also provides & procedure for cleaning the demineralized
water piping and air separation type oxygen-nitrogenplants.
