Machinery Reliability Audits and Reviews 233

Typical audit interview questions. (Continued)

What major problems have occurred in recent years?
How is machinery monitored?
-Operations
-Technical
-Maintenance
Are data collected for long-term records and future reference?
-.Data distribution routine: How done, where sent?
Do you have a means of rapidly relating operational problems with their impact on
process machinery? If so, how is it done?
What would you like to see implemented in order to improve the reliability of the
dant?
