Establish a safe state, then check leakage location, door closure, hot structure and furnace-pressure/exhaust conditions before confirming the repair.

Review recoverable condition, process fit, operating costs and implementation over the same life-cycle boundary.

Establish a comparable curve before investigating loading, heat input, utilities, insulation, seals, circulation and measurement.

Control the immediate risk, then diagnose the door interface, mechanisms, geometry, pressure, lining and operating state together.

Confirm approved procedures, authorised personnel, equipment state, loading, interlocks and abnormal-event responsibilities.
