Run a Simple FMEA on Backup Aeration
Use FMEA steps to prioritize backup-aeration failures before an oxygen event.
Backup blower starts, but air reaches the far pond after nine minutes during a drill at high biomass. FMEA: failure mode -> effect -> cause -> detection -> control The common trap is checking whether the machine turns on and calling the backup ready. Fish do not need a running machine; they need oxygen delivered at the pond within the response window. Failure mode List ways the backup path can fail: blower does not start, generator trips, valve closed, hose leak, fuel unavailable, operator cannot execute sequence. FMEA starts with specific failure modes, not generic worries. Specificity makes controls testable.…
