NFPA^® 56, Standard for Fire and Explosion Prevention During Cleaning and Purging of Flammable Gas Piping Systems, provides comprehensive requirements to help develop safe operating procedures.

• Added criteria on when piping is to be purged out of service as well as when it is to be cleaned
• Addition of a new annex on the consideration of human factors when purging to help users identify key human factors to consider when purging operations are conducted
