Top 10 Safety Mistakes in Industrial Control Panels (And How to Avoid Them)
- 3 days ago
- 3 min read
Control panels sit at the heart of industrial automation, but when poorly designed, they quickly become a major safety risk.
From electrical hazards to maintenance issues, the most dangerous problems are often designed in from the start.
For compliance managers, engineering teams, project managers, and site operators, these risks translate directly into downtime, safety incidents, and compliance exposure.
Poorly Designed vs Well-Designed Control Panels
Area | Poor Panel Design | Safe, Well-Designed Panel |
Labelling | Missing or inconsistent | Clear, standardised tagging |
Electrical Layout | Mixed voltages, cluttered | Segregated, structured zones |
Space | Overcrowded | Designed for access and expansion |
Wiring | Disorganised | Routed, labelled, contained |
Isolation | Hard to identify | Clearly accessible and safe |
Documentation | Missing or outdated | Accurate and aligned to build |
Compliance | Inconsistent | IEC, BS, CE/UKCA aligned |
Maintenance | Difficult and unsafe | Designed for real-world access |
Protection | Weak or incorrect | Proper earthing and protection |
Lifecycle | Short-term thinking | Long-term reliability focus |
This is where safety is either built in, or designed out.
1 Poor Labelling and Identification
Unclear or inconsistent labelling makes even simple systems difficult to understand.
The risk:
Increased human error
Incorrect isolation during maintenance
Best practice:
2 Inadequate Electrical Segregation
Mixing high and low voltage components introduces unnecessary risk.
The risk:
Electrical faults and interference
Increased chance of accidental contact
Best practice:
Physical and logical separation
Clearly defined panel zones
3 Overcrowded Panels
Designing to “fit everything in” creates long-term safety and maintenance issues.
The risk:
Heat build-up
Unsafe working conditions
Wiring errors
Best practice:
Design for space, not just fit
Allow for future expansion
4 Poor Cable Management
Unstructured wiring reduces visibility and increases failure risk.
The risk:
Difficult fault tracing
Cable damage or short circuits
Best practice:
Structured cable routing
Proper containment systems
5 Lack of Clear Isolation Points
If engineers cannot safely isolate systems, risk increases significantly.
The risk:
Unsafe maintenance
Live working conditions
Best practice:
Clearly labelled isolation points
Designed lockout/tagout (LOTO) procedures
6 Incomplete or Missing Documentation
Working without accurate documentation is a major operational risk.
The risk:
Incorrect interventions
Delays during maintenance and upgrades
Best practice:
Up-to-date AutoCAD or EPLAN drawings
Documentation aligned with actual build
7 Ignoring Standards (IEC, BS, CE/UKCA)
Standards exist to prevent exactly these issues.
The risk:
Legal and compliance exposure
Unsafe system design
Best practice:
Full alignment with IEC and BS standards
Proper CE or UKCA processes
8 No Consideration for Maintenance Access
Panels designed without real-world use in mind create ongoing risk.
The risk:
Unsafe maintenance conditions
Increased repair time
Best practice:
Logical layout
Safe access zones for engineers
9 Poor Earthing and Protection Design
Electrical protection is non-negotiable.
The risk:
Electric shock
Equipment damage or fire
Best practice:
Proper grounding strategy
Correct protective devices
10 Designing for Installation, Not Lifecycle
Short-term thinking creates long-term problems.
The risk:
Systems degrade over time
Increased risk during modifications
Best practice:
Lifecycle-focused design
Systems built for long-term maintainability
The Bigger Issue: Why These Mistakes Happen
Most safety issues are not intentional.
They happen because:
Safety is not considered early enough
Projects are rushed
Teams work in silos
Integrators focus on delivery, not long-term operation
This is where risk is introduced before installation even begins.
How to Avoid These Issues Entirely
The safest control panels are built on:
Clear engineering standards from day one
Consistent, structured design approaches
Full documentation and traceability
Lifecycle and maintenance thinking

Clear and easy to understand
Fully compliant with relevant standards
Safe to operate and maintain
Built for long-term reliability
We do not just build panels.
We build systems that reduce risk across your entire operation.
Control Panel Safety Mistakes FAQ's
What are the most common control panel safety mistakes?
Common mistakes include poor labelling, overcrowded panels, lack of electrical segregation, missing documentation, and failure to follow standards. These issues increase risk, reduce visibility, and make maintenance unsafe.
Why is control panel design important for safety?
Control panel design directly impacts how safely systems can be operated and maintained. Poor design increases the likelihood of electrical faults, human error, and unsafe working conditions.
What standards apply to industrial control panels in the UK?
Industrial control panels typically need to comply with IEC standards, British Standards (BS), and CE or UKCA marking requirements, depending on the application and installation.
How do you make a control panel safe?
A safe control panel requires clear labelling, structured wiring, proper electrical segregation, compliant design, accessible isolation points, and accurate documentation aligned with the physical system.
Need to Review Your Existing Panels?
If you are unsure whether your current panels meet modern safety expectations, or you are planning an upgrade, early review makes a measurable difference.
