Understanding the real causes of incidents

Did you know that accidents start before someone gets hurt.

In many small and medium-sized businesses, when an incident happens the first question asked is often: “Who made the mistake?” While this reaction is understandable, it rarely leads to meaningful prevention. Incidents almost never occur because of one person or one action. They develop over time through a combination of system weaknesses, environmental conditions and human behaviour.

Understanding the root causes of incidents allows organisations to address the underlying conditions that make accidents possible rather than repeatedly correcting symptoms.

To truly improve workplace safety and comply with the Occupational Health and Safety Act (OHSA), employers and employees must shift from blame to understanding. Compliance is not simply about having documents on file; it is about ensuring that systems function effectively in daily operations and that risks are controlled before someone is injured.

Incidents start long before the injury

Think of an incident like a tree. The injury or damage you see is only the trunk. The real causes lie beneath the ground, hidden in the roots.

Understanding the root causes of incidents means digging below the surface to identify weaknesses in planning, communication, supervision, equipment and work design.

These roots generally fall into three categories:

Organisational factors — The system around the worker

Many incidents originate in the way work is organised rather than how work is performed. Organisational weaknesses quietly create conditions where mistakes become likely.

Common workplace examples:

• Unclear instructions or procedures
  Employees may receive verbal instructions that differ from written procedures, or procedures may be outdated, overly complex or not aligned with actual work practices. In these situations, workers improvise, increasing risk.
• Lack of training or supervision
  New employees are often expected to “learn on the job” without structured induction. Supervisors may oversee too many staff members to provide proper oversight, allowing unsafe practices to develop unnoticed.
• Poor communication between management and staff
  Changes in processes, equipment or expectations may not be formally communicated. Employees may hesitate to report hazards if they feel their concerns will be ignored.
• Unrealistic deadlines or production pressure
  When production targets are prioritised without considering safe working speeds, employees are indirectly encouraged to take shortcuts to keep up.
• Employees unsure of what is expected of them
  Vague job roles and shifting responsibilities can result in critical safety tasks being overlooked because everyone assumes someone else is responsible.

When employees must “figure things out themselves”, they will create their own methods. These methods often work until the day they don’t. For employers, this means compliance is not just paperwork. A procedure only protects you if it is understood, practical and enforced consistently.

Human factors — Understanding people, not blaming them

Human error is often listed as the cause of an incident, but this is usually incorrect. Human error is normally the last link in a chain, not the root cause.

Understanding the root causes of incidents requires distinguishing between different types of human behaviour.

Human errors fall into two main groups:

Unintentional errors

These show system weaknesses:

• Slips (pressing the wrong button)
  This may occur where controls are poorly labelled or positioned too closely together.
• Lapses (missing a step)
  Often linked to distraction, fatigue or interruptions during a task.
• Misjudgement due to unfamiliar tasks
  When employees perform tasks without adequate training or guidance.
• Decisions based on incorrect assumptions
  For example, assuming a machine is isolated when it is not properly locked out.
• Fatigue or stress
  Long working hours, staff shortages or personal stressors reduce attention and increase risk.

These require training, supervision, better procedures, or improved working conditions, not discipline. They indicate that the system did not sufficiently support safe performance.

Deliberate violations

Employees knowingly bypass rules, often because:

• The job cannot be done within the allowed time
  Safe methods may be perceived as too slow under production pressure.
• The correct method is impractical
  Equipment may be stored too far away, or procedures may not reflect real working conditions.
• Production pressure is high
  Workers may feel that output is valued more than safety.
• “This is how we’ve always done it”
  Unsafe shortcuts become normalised over time.

This is not purely misconduct it is a management signal. It indicates the system encourages risk-taking, even if unintentionally. Punishment alone will never fix this. Leadership, realistic planning and proper risk management will.

Material factors — Tools, equipment and environment

Even a well-trained employee in a well-managed workplace will be exposed to risk if the environment is unsafe. Understanding the root causes of incidents includes evaluating the physical conditions under which work is performed.

Typical contributors:

• Poor maintenance
  Equipment breakdowns, leaks or worn components increase the likelihood of injury.
• Defective equipment
  Tools that are damaged or unsuitable for the task create unnecessary hazards.
• Missing guards or protection
  Safety devices removed for convenience expose workers to moving parts or hazardous processes.
• Disorganised work areas
  Poor housekeeping leads to slips, trips and restricted emergency access.
• Inadequate lighting or layout
  Poor visibility or cramped spaces increase the risk of error.

A safe workplace requires reliable tools and proper housekeeping. Preventative maintenance and regular inspections are not optional extras they are essential controls that reduce both injury and legal exposure.

What This Means for Employers

Under the OHSA, employers must provide a workplace that is safe “as far as reasonably practicable.” This requires more than reacting to accidents it requires preventing them through structured systems and active leadership.

Practical actions:

• Conduct meaningful risk assessments
  Identify real hazards in daily operations, not just theoretical risks.
• Investigate near misses, not only injuries
  Near misses provide early warning signs before serious harm occurs.
• Train staff on why procedures exist
  Understanding the reason behind a rule improves compliance.
• Encourage reporting without fear of blame
  Create a culture where raising concerns is seen as responsible behaviour.
• Review workload and deadlines
  Ensure productivity targets do not indirectly promote unsafe practices.
• Maintain equipment proactively
  Scheduled inspections and servicing prevent failures that could cause injury.

What This Means for Employees

Safety is a shared responsibility. Employees play a critical role by:

• Following procedures even when shortcuts appear faster.
• Reporting hazards early. Small issues often become major incidents if ignored.
• Reporting near misses. These are learning opportunities, not admissions of guilt.
• Asking when unsure for clarification to prevents assumptions.
• Avoiding shortcuts. Temporary time savings can result in permanent consequences.
• Supporting a safety culture by encouraging colleagues to work safely strengthens the entire system.

Reporting a near miss is not causing trouble, it is preventing an injury.

Building a Culture of Prevention

A workplace becomes safe when people stop asking “who is at fault?” and start asking “what allowed this to happen?” When incidents are properly analysed, people learn, systems improve, legal risk decreases, productivity increases and trust grows. Prevention is always cheaper than reaction both financially and humanly.

Every incident is a message from the workplace system. Fix the system, and the behaviour improves automatically. Analyse the causes. Act on them. Prevent the next incident. A safe workplace is not achieved by luck, but it is built through understanding, leadership and cooperation.

Strong safety culture protects both people and business.
