Identifying the surface and root causes of accidents
Most accidents are caused by an unsafe condition in the workplace, the unsafe actions of an employee, or both. These surface causes show how an accident happened. To prevent future incidents, however, you’ll need to identify the root causes of why the accident happened.
Examples of hazardous conditions might include faulty machine guards, water on the floor, ice in a parking lot, or unstable stacks of material. These conditions may cause injury through unsafe employee actions, such as using a machine with a faulty guard. Employee actions can cause injuries even without a hazardous condition, such as misusing tools.
Employers sometimes blame employee behaviors for injuries, but this won’t address the root cause. If an employee reports the problem, the accident should be avoided, so employee actions can actually help prevent accidents. Addressing root causes helps you reach the prevention stage.
Deeper or root causes
The root cause of an accident is usually a system failure. Potential root causes could include:
- Workplace culture prioritizes production over safety. This can motivate employees to skip safety procedures that they believe slow them down, such as using a machine with a defective guard or bypassing the guard to clear a jam.
- Mentors explain “shortcuts” to new workers. New employees may be taught the correct way to perform a task, but later be told of a “better” or “faster” way by an experienced mentor. A recent hire is unlikely to question a senior coworker, even if the “shortcut” increases the risk of injury.
- Lack of supervisor knowledge or enforcement. Supervisors must know the safety rules and know what a violation looks like. They must also have the confidence to enforce those rules, even with employees who have been with the company for many years. Ignoring problems sends a message that violations are acceptable.
There can be many other root causes, but the key is that even if an employee’s actions contributed to an accident, the employee may not be fully to blame. Identify the motivation or reason for the employee’s actions, then determine what steps can be taken to change those behaviors.
Blaming an employee won’t address system failures that could result in future accidents to other employees. Injury prevention requires identifying and addressing the root cause or motivation for the unsafe conduct.
