Phase Inspection. 1  Inspect the electrical system as a whole including outlets, GFCI & AFCI protection, switches, fixtures, panels, circuit breakers & disconnects. 2  Inspect the plumbing for any visible leaks, drips, water supply, proper venting of the drains and waste lines.
Also called: potential failure modes and effects analysis; failure modes, effects and criticality analysis (FMECA). Failure modes and effects analysis (FMEA) is a step-by-step approach for identifying all possible failures in a design, a manufacturing or assembly process, or a product or service.
