Human Performance – Recognizing Error Traps
No one comes to work expecting to make a mistake or get injured. Still, people are fallible. We forget details, get distracted, make assumptions, and sometimes take shortcuts. These are normal human behaviors—not character flaws.
Simply telling someone to “be more careful” is not enough. Human Performance focuses on identifying the conditions that increase the chance of error and putting controls in place before those errors lead to incidents.
Why This Matters
Many incidents occur when employees are rushed, fatigued, distracted, relying on memory, adjusting to changing conditions, communicating unclearly, or feeling pressured to “just get it done.” These conditions are known as error traps.
We may not be able to remove every error trap, but we can learn to recognize them, pause, confirm the plan, and control the risk before something goes wrong.
Common Error Traps
Time Pressure: Production demands can push employees to work faster, skip steps, or take shortcuts. Ask yourself, “Am I changing my normal process just to save time?”
Complacency: Repetitive tasks can feel routine and create a false sense of security. Give every task your full attention, no matter how often you have done it.
Assumptions: Do not assume equipment is de-energized, inspections are complete, materials are correct, or another trade communicated a change. Verify the condition before moving forward.
Distractions: Phone calls, radio traffic, side conversations, and shifting priorities can cause employees to lose focus. If you are interrupted during a critical step, stop, reassess, and restart if needed.
Fatigue: Fatigue lowers focus, slows reaction time, and increases the chance of poor decisions. If you are exhausted or struggling to stay focused, speak with your supervisor.
Practical Ways to Reduce Errors
Before work begins, review the plan, complete a strong pre-task plan, verify hazards and controls, confirm roles, limit distractions, and ask questions when something does not seem right.
During work, slow down for critical steps, communicate changes right away, use peer checks when appropriate, and stop work if conditions change.
Crew Discussion
Which error trap affects our crew the most?
What distractions are present on our project today?
What assumptions could cause an incident if we fail to verify them?
How can coworkers help each other prevent mistakes?
Supervisor Expectations
Leaders should encourage questions, reduce unnecessary production pressure, reinforce pre-task planning, support proper stop-work decisions, and use close calls as learning opportunities.
Mistakes are part of being human. Injuries do not have to be. A strong safety culture recognizes conditions that increase the chance of error and acts before those errors cause harm.
