Episode 131 introduces a simple but surprisingly powerful hazard‑identification tool: the 3×5‑inch index card technique. Dr. Ayers highlights how this low‑tech method cuts through noise, forces clarity, and helps employees focus on the single most important hazard in their work area.
Limiting employees to a 3×5 card forces them to identify what truly matters. It sharpens hazard recognition by removing clutter and encouraging concise, high‑value observations.
The small size forces employees to prioritize the most critical hazard, not a laundry list.
It reduces overwhelm—people don’t need to find everything, just the biggest risk.
It encourages participation from employees who may be hesitant to speak up in larger formats.
The simplicity makes it easy to use during toolbox talks, shift meetings, or field visits.
Each employee receives a 3×5 card.
They write down one hazard they see in their area or task.
Cards are collected and reviewed as a group.
Supervisors or safety leaders identify patterns, recurring issues, or high‑severity risks.
The team discusses controls, fixes, or follow‑up actions.
The hazards employees consider most significant.
Blind spots in leadership’s understanding of day‑to‑day risks.
Repeated issues that may indicate systemic problems.
Differences in perception between departments, shifts, or roles.
Quick, low‑cost hazard identification.
High engagement across all levels of the workforce.
Better communication between employees and supervisors.
A simple way to gather real‑time data on emerging risks.
Helps build a culture where hazard recognition becomes routine.
Employees practice identifying hazards in a focused, manageable way.
The constraint of the card builds the skill of prioritization.
It creates a safe, low‑pressure environment for participation.
The 3×5 index card technique is a deceptively simple but highly effective hazard‑identification tool. By asking employees to identify just one meaningful hazard, organizations gain clearer insights, stronger engagement, and a more proactive safety culture.
