Risks

The walk is done once and not repeated

Risk	The first walk fixes the largest leaks, and then no date is set for the next. New leaks open as hoses and couplings wear.
Early sign	A quarter passes with no new tag on a leak, and the pumping minutes at a meal break creep up.
Mitigation	One named person, a date each quarter, and every reading on one sheet.
Impact	About $6,400 per year: what the leaks add to the figure.

Risk	Pressure is lost along the line, so the farthest press gets less than the compressor room sends. One step too many leaves that press short.
Early sign	On the day of a step, parts stick in the mold at one press, or a moving part of its mold slows down.
Mitigation	Steps of two psi, a full shift between them, and the farthest press watched each time.
Impact	Slower cycles or rejected parts at that press until the setting goes back up.
