This template supports final inspections of air break switches before piercing. It guides field crews through confirming customer presence, checking for damage, verifying grounds, torque marks, No-Ox compound on dissimilar metals, and installed open/close markers. It covers smooth handle operation, simultaneous blade contact and separation on arc-horns across phases, and consistent full-open stops. The checklist documents equipment IDs, observations, and comments, and captures signatures from the inspector, contractor commissioner, customer representative, and commissioning manager to confirm readiness for irreversible piercing operations.
