Human Performance (HP) – Catching Mistakes Before They Turn into Incidents
Why This Matters
Electrical work in the field moves fast and comes with real risk. We work around energized equipment, overhead hazards, ladders, lifts, tight spaces, and other trades all at once. Even experienced people can make mistakes when the pressure is on.
Human Performance is not about blaming someone when something goes wrong. It is about understanding that people make mistakes and putting the right planning, communication, and checks in place so those mistakes do not lead to injuries or damage.
The goal is simple: catch the mistake before somebody gets hurt.
Key Human Performance Principles
People Are Fallible
Even experienced electricians can:
- Miss a step
- Lose focus
- Make assumptions
- Become distracted
- Forget details under pressure
When we recognize that, we stop depending only on memory or experience and start building stronger work habits.
Error Likely Situations Exist
Certain conditions increase the chance of mistakes:
- Rushing to meet deadlines
- Fatigue
- Working overtime
- Poor housekeeping
- Distractions
- Incomplete information
- Changes to scope or plans
- Congested work areas
- Working around energized equipment
- Repetitive tasks leading to complacency
When crews spot these conditions early, they can slow down, reset, and stay in control of the job.
Communication Prevents Errors
Bad communication causes jobsite mistakes every day.
Examples:
- Assuming circuits are de-energized
- Assuming another trade completed a task
- Not communicating overhead work
- Incomplete shift turnover information
- Unclear direction from supervision
Good communication includes:
- Pre-task planning discussions
- Repeat-backs
- Clarifying questions
- Verifying understanding
- Stopping work when unsure
Human Performance Tools
Pre-Task Planning
Take time to review:
- Scope of work
- Hazards
- Energization status
- Required PPE
- Access and egress
- Material handling
- Critical steps
- Changes in the work area
A solid pre-task plan helps the crew spot where the job can break down before work starts.
Take a Moment Before the Task
Before starting:
- Pause
- Focus on the task
- Verify conditions
- Confirm tools and materials
- Identify what could go wrong
Taking a few seconds to pause can keep a small mistake from becoming a serious incident.
Verify Critical Steps
For high-risk tasks:
- Verify zero energy
- Check labels and drawings
- Confirm lockout/tagout
- Double-check measurements and terminations
- Validate equipment is secured before release
Do not assume—verify it.
Encourage Stop Work Authority
Everyone has the authority and responsibility to stop work when:
- Conditions change
- Hazards are unidentified
- The task is unclear
- Something does not feel right
Stopping work is what professionals do when something is off.
Learn from Mistakes and Near Misses
A near miss is a warning sign. It gives us a chance to fix the problem before someone gets hurt.
Instead of asking:
“Who messed up?”
Ask:
- What conditions led to the error?
- What barriers failed?
- What can we improve?
- How do we prevent recurrence?
Common Human Performance Traps in Electrical Construction
- Assuming equipment is de-energized
- Rushing conduit installation or terminations
- Working distracted around overhead activities
- Skipping verification steps
- Poor ladder setup
- Failure to communicate changes
- Working while fatigued
- Taking shortcuts because “we’ve done it before”
Discussion Questions
1. What conditions on this project make errors more likely?
2. Have we seen examples where a small mistake could have led to a serious incident?
3. What verification steps are most important in our work?
4. Are crews comfortable stopping work when something does not look right?
Key Takeaway
Human Performance means building habits, communication, and jobsite checks that keep mistakes from turning into incidents. Strong crews catch risks early, talk clearly, verify the critical steps, and look out for each other.
Slow down, stay sharp, verify the work, and say something when it does not look right.
