What this type means

Failure to certify correction of a Class 1, immediately hazardous violation. It is a violation about ignoring another violation: the underlying hazard was cited and the owner never certified fixing it.

How it gets cleared

Correct the underlying hazardous condition and file the certificate of correction for it; this type exists to escalate that filing from optional to enforced.
