Electrical Room / CCR Room Inspection

A standardized inspection methodology for AGL electrical rooms, CCR rooms, control rooms, and associated electrical/control equipment areas — verifying room environmental conditions, equipment accessibility, cabinet condition, cable and control-wiring integrity, auxiliary supplies, emergency lighting, housekeeping, and electrical/fire safety. The electrical/CCR room is the operational center of the AGL power system, so inspection must confirm both room condition and the underlying electrical conditions necessary for safe, reliable operation.

Safety control — Internal CCR inspection shall only be performed by authorized/competent personnel under the applicable electrical isolation, LOTO, and safety procedure. Routine visual checks must not be interpreted as authorization to access energized equipment. A routine room inspection must never inadvertently become unauthorized energized electrical work.

Frequently Asked Questions

Quick answers about electrical room / ccr room inspection in the AGL Inspection Handbook.

Q1What is Division 19 — Electrical Room / CCR Room Inspection in the AGL Inspection Handbook?

Division 19 contains 12 published topics giving a standardized inspection methodology for AGL electrical rooms, CCR rooms, control rooms and associated electrical and control equipment areas. It verifies room environmental conditions, accessibility, cabinet condition, cable and control-wiring integrity, auxiliary supplies, emergency lighting, housekeeping, and electrical and fire safety.

Q2Why is the electrical or CCR room inspected as a whole?

The electrical or CCR room is the operational center of the AGL power system, so the inspection confirms both the condition of the room and the underlying electrical condition of the equipment in it.

Q3What is the two-level inspection model?

Level 1 is a routine visual and operational inspection covering housekeeping, access, water leakage, ventilation, temperature, external cabinet condition and labels, visible cable condition, emergency lighting, fire equipment, safety signage and working clearance. Level 2 is for authorized electrical personnel only and covers CCR internal components and terminals, electrical connections and control wiring, internal protection and cooling components, and electrical measurements, tightness and tests.

Q4Which conditions require immediate escalation?

Under the applicable airport procedure, the division lists water entering or threatening CCR or electrical equipment, smoke, burning smell, arcing or overheating evidence, exposed energized conductors, major cabinet damage or loss of required ventilation or cooling, abnormally high room temperature, fire-system deficiency or a blocked emergency exit, inadequate electrical working clearance, significant cable damage or loss of a critical auxiliary supply, and any unsafe electrical condition.

Q5What status classifications are used in this division?

Every observation is assigned one of four statuses. Normal means the equipment or condition is satisfactory and operating as expected. Defective means an abnormality or defect exists but the equipment remains operational or the condition does not require immediate withdrawal. Unserviceable means the equipment or system is not available for its intended function. Immediate Action Required means the condition presents an operational, electrical, safety or airside risk requiring immediate escalation and action.

Q6What should an electrical or CCR room inspection record include?

The record includes the date and time, inspector name and designation, room or area inspected, equipment or system inspected and its identification and location, observations, status classification, defect description where applicable, immediate action taken, person or department notified, corrective-action reference, and closure date and time with inspector sign-off.

Q7Do airport procedures take precedence over this handbook?

Yes. This handbook is an uncontrolled educational reference, not an approved procedure. The airport's approved inspection schedule, SMS procedures, ATC instructions, NOTAM procedures and local aerodrome regulations always take precedence, and the current revision of any official document should be verified before use.

Q8Can I download a printable checklist for each inspection topic?

Yes. Each inspection topic has a Download as Word option that produces an uncontrolled Word checklist template (description, a tick-box inspection table and an inspector sign-off block) for personal reference and internal training, to be reviewed and adopted under the user’s own document control.
