What health behaviour science teaches us about workplace safety
Introduction
There is no shortage of safety rules in today’s workplaces. Procedures are written, updated, laminated, and posted. Training sessions are delivered, attendance is recorded, and compliance checklists are carefully completed. Yet injuries still happen. Near misses still go unreported. Workers still take shortcuts they know they shouldn’t. If rules alone were enough to keep people safe, workplaces would be injury-free by now.
Despite the best intentions, safety programs that focus primarily on compliance risk overlook a deeper truth: safety is less about what is written on the wall and more about what happens in people’s minds and behaviours. Public health and behavioural science teach that people do not change simply because rules exist; they change when belief, motivation, culture, and context align.
Across the occupational safety community, there is growing recognition of this human dimension. Safety discussions repeatedly reveal that strong policies and procedures alone are not enough. What matters most is how workers, supervisors, and leaders actually implement safety in everyday work. In fact, winners of the 2024 5-Star Safety Culture recognition emphasize training, engagement, and human factors as central to their success, not just compliance with rules. To meaningfully reduce injuries and keep workers safe, workplaces must shift their focus from rules alone to the human behaviours that ultimately determine whether those rules are followed.
Practical recommendations — Applying the health belief model in real workplaces
Health behaviour science reveals that human behaviour is influenced by much more than knowledge alone. Models like the Health Belief Model explain that people are more likely to act safely when they believe a risk is personally relevant, understand the benefits of safe action, and feel capable of doing it. These cognitive factors are shaped by experience, social norms, and environmental pressures, all elements that only become fully visible in the field.
Understanding safety through the Health Belief Model helps explain why some programs change behavior while others stall. But theory only matters if it translates into actions that workers can feel and relate to. The most effective safety programs recognize that people don’t just respond to rules. They respond to meaning, identity, and connection.
Below are four practical, behavior-driven recommendations rooted in the Health Belief Model and grounded in everyday workplace realities.
1. Perceived susceptibility
Make risk personal by connecting safety to what workers value.
Many workers intellectually understand risk but emotionally distance themselves from it. “It won’t happen to me” is not ignorance. It’s human nature. To overcome this, safety programs must make risk personally relevant, not abstract.
One simple but powerful example seen in many workplaces is encouraging workers to place photos of their families inside lockers, on toolboxes, or near workstations. The message is subtle but effective: you are not just protecting yourself—you are protecting the people who depend on you. This approach shifts safety from a rule to a responsibility rooted in personal life.
Other effective strategies include sharing stories of real incidents involving similar tasks or equipment, especially when those stories come from coworkers rather than management. When workers see themselves in the scenario, risk stops feeling distant and starts feeling real.
2. Perceived severity
Frame consequences in human terms, not just injury statistics.
Safety messaging often emphasizes numbers, incident rates, lost-time injuries, and compensation costs. While important, these metrics rarely influence day-to-day decisions on the floor.
Behavior science shows that people respond more strongly to consequences they can imagine living with. For example, instead of saying, “This task has resulted in multiple recordable injuries,” a supervisor might explain how a repetitive strain injury could mean chronic pain, limited mobility, or being unable to play with one’s children after work.
Some organizations reinforce this by inviting injured workers (when appropriate) to speak about how an incident affected their lives beyond the workplace. These conversations humanize safety without resorting to fear tactics. They make clear that safety is not about avoiding paperwork. It’s about preserving the quality of life.
3. Perceived barriers & self-efficacy
Remove barriers by designing safety around how work actually happens.
One of the fastest ways to undermine safe behavior is to design procedures that look good on paper but fail under real conditions. Workers take shortcuts not because they don’t care, but because the system makes the safe way harder than the unsafe one.
For example:
- PPE that is uncomfortable or poorly fitted will always lead workers to remove it.
- Procedures that require extra steps during peak production times.
- Tools stored far from the point of use will encourage improvisation.
Organizations that apply a behavioral lens involve workers directly in identifying these barriers. When employees help redesign workflows, select equipment, or adjust procedures, safety becomes doable. Training then focuses on building confidence through practice, not just instruction, so workers feel capable of performing tasks safely even under pressure.
This is also where field experience matters most. Safety decisions made without firsthand exposure to work conditions often underestimate barriers and overestimate compliance.
4. Cues to action
Reinforce safe behavior through belonging, recognition, and daily cues.
People are more likely to act safely when they feel they belong and when safe behavior is visibly valued. In strong safety cultures, workers don’t follow rules just to avoid discipline. They do so because safety is part of who they are as a team.
Examples include:
- Supervisors starting shifts with brief, genuine safety check-ins rather than scripted talks
- Peer-to-peer reminders framed as looking out for one another, not policing
- Public recognition for safe decisions, especially when those decisions slow production or require extra effort
When workers feel respected, included, and seen as partners, safety becomes a shared value rather than an obligation.
Why this approach works
The Health Belief Model reminds us that behavior is shaped by perception, emotion, and environment. When safety management speaks to what people care about, removes practical barriers, and reinforces positive behavior through connection and recognition, rules stop feeling imposed.
These practices are not about being soft. They are about being effective. In workplaces where pressure, fatigue, and complexity are everyday realities, safety systems that acknowledge human behavior are the ones that endure.
