Unsafe Access for Maintenance and Fault Finding

Most electrical safety incidents do not occur during normal operation.
They often occur during maintenance.
​
A maintenance engineer opens a control panel to diagnose a fault. A contractor attempts to test a circuit under pressure to restore production. An electrician works in a cramped enclosure with poor access to components.
​
What should be a routine maintenance task can quickly become a safety risk.
For Health & Safety and Compliance Managers, unsafe access to control panels is one of the most common, and often overlooked, sources of electrical and operational risk.
​
At Stratos Control Systems, we frequently encounter industrial control panels that control machinery effectively, but were never designed with safe maintenance and fault finding in mind.
The result is increased risk to personnel, longer downtime and greater compliance exposure.
Why Safe Maintenance Access Matters
Industrial control panels require ongoing maintenance throughout their lifecycle.
​
Engineers regularly need access to:
-
Circuit breakers
-
PLCs
-
Variable speed drives
-
Power supplies
-
Safety relays
-
Network equipment
-
Terminal connections
-
Communication devices
​
If access is difficult, engineers may be forced to:
-
Work in awkward positions
-
Reach around live equipment
-
Remove multiple components
-
Leave panel doors open during operation
-
Bypass safe working practices to save time
​
Each of these actions increases risk.
The Link Between Maintenance Access and Safety
A control panel may meet its functional requirements while still creating hazards during maintenance.
Poor access can contribute to:
​
Electrical Shock Risk
Restricted access can make isolation and verification procedures more difficult.
​
Arc Flash Exposure
Engineers may need to work closer to live equipment than necessary.
​
Human Error
Poor visibility and difficult access increase the likelihood of mistakes.
​
Manual Handling Risks
Heavy doors, awkward positions and difficult component access can create physical hazards.
​
Extended Exposure Time
The longer maintenance tasks take, the greater the opportunity for incidents.
Common Signs of Unsafe Control Panel Access
Health & Safety Managers should investigate if:
​
Components Are Difficult to Reach
Critical devices should be accessible without removing multiple components.
​
Engineers Must Work Around Live Equipment
Maintenance activities should not require unnecessary exposure to live electrical systems.
​
Wiring Is Congested
Overcrowded panels make inspection and fault finding more difficult.
​
Labels Are Missing or Difficult to Read
Clear identification is essential for safe maintenance.
​
Isolation Devices Are Poorly Located
Engineers should be able to isolate equipment quickly and safely.
​
Panel Layouts Have Evolved Over Time
Years of modifications often create access challenges that were never considered in the original design.
​
Why Poor Access Increases Downtime
Unsafe maintenance access is not only a safety issue.
It is also a productivity issue.
​
When engineers struggle to access equipment:
-
Fault diagnosis takes longer
-
Repairs take longer
-
Restart times increase
-
Maintenance costs rise
​
Many facilities discover that poor panel design contributes directly to operational inefficiency.
​
Common Problems Found During Control Panel Assessments
At Stratos Control Systems, we frequently identify:
-
Overcrowded enclosures
-
Poor cable routing
-
Inaccessible terminal blocks
-
Obstructed safety devices
-
Inadequate working clearances
-
Missing component labels
-
Poor documentation
-
Difficult isolation arrangements
-
Legacy modifications affecting accessibility
-
Inadequate lighting around panels
​
These issues often develop gradually as systems evolve.
