Root cause of incident: The work carried out in construction projects is considered high risk due to workplace hazards as it facilitates the occurrence of work accidents that affect the physical, mental and social integrity of employees as well as the productivity of companies. For this reason, the purpose of this article is to analyze the causes and consequences of work accidents. Workplace accidents can be generated by immediate or basic causes (usually called underlying causes or root causes).
According to statistics from the International Labor Organization (ILO), in the World Day for Safety and Health at Work report, "Around 4% of global Gross Domestic Product (GDP) is lost to the cost of casualties, deaths and illnesses in the form of absences from work, treatment and disability and death benefits" (ILO, 2005).
The pyramid theory of accidents developed by Bird in 1969
revealed that for every serious accident, there are 10 minor accidents, 30
accidents with property damage and 600 accidents without visible damage or
loss.
The immediate (direct cause of incident) ones are those that
produce the accident directly and are made up of unsafe acts (inappropriate
behaviours of workers that can cause a work incident) and unsafe conditions
(facilities, equipment, machinery and tools that are in poor condition and put
workers at risk of suffering an accident).
But to achieve an effective solution to work accidents, it
is essential to recognize root cause of incident, which gives rise
to the immediate causes made up of personal factors (incorrect work habits,
incorrect use of equipment, tools and facilities; defects physical or mental,
hearing deficiencies, etc.) and work factors (Poor supervision and leadership;
Inadequate policies, procedures, guides or practices; Inadequate planning
and/or programming of work.
The direct cause of the incident
We call the causes closest to the accident, which are those
that materialize its, Immediate Causes. They are those related to the material
and environmental conditions of the workplace (unsafe conditions) and those
related to the personal actions of the workers who participated in the accident
(unsafe acts).
These are the causes that are found in the sequential process close to the event that triggers the accident. The fundamental thing is to discover at this stage the immediate causes, so that once they are eliminated, the accident cannot materialize or it is very difficult for it to materialize. The immediate causes are classified into two groups, of which one or more than one of each group must be noted. Muniriyathse (safety zone) brought to you some examples of unsafe acts and conditions.

Underlying or basic cause or root cause of incident
In this blog, we will deal with the root cause of incident. They are the causes that fundamentally correspond to failures in the
application of the prevention system, which may be of a personal nature
(personal factors) and work organization (work factors).
They are the reasons that explain why unsafe acts and conditions exist. Its analysis allows for deeper, more extensive and more exhaustive control of the working conditions that can give rise to work accidents. Some authors also call them originating causes, real causes, indirect causes, underlying causes or contributing causes.
Root causes of work accidents
Basic Causes help explain, among other things, why people
perform unsafe acts. A worker will not be able to execute an appropriate work
procedure if he or she has not been previously taught that procedure; training
and information are at the heart of the way we carry out our actions.
Similarly, a worker who handles work equipment that requires
precise and specialized handling will not be able to use it efficiently and
safely if he or she has not been properly trained in its use. Training and
periodic practices are also essential to carry out good practices.
It also influences our way of doing things, and our personal
physiological and psychological conditions, in other words, each job has
demands for which the worker who performs it must be suitable.
Root or underlying causes also help explain why unsafe conditions exist. The existence of inadequate maintenance of work equipment or wear and tear due to the use of materials can also be cited as factors that lead to the existence of unsafe conditions.
Classification of the root causes of incident
Three common reasons cause a failure in the prevention
system.
Existence of:
- Inadequate occupational risk prevention system
- Insufficient or inadequate system procedure
- Failure to comply with any aspect of the system
As an example and on a generic basis among others, we can find the following root causes of incident:
Personal factors
Within the root causes of incident, we distinguish
personal factors, which refer to aspects that concern the attitudes and skills
of each worker and job. These factors represent a significant risk of a
workplace accident when a worker who performs a dangerous function has little
experience, when a working day is especially long or tiring, or when the work
environment is psychologically exhausting.
Therefore, a young and inexperienced worker in work fields
that include dangerous machinery such as construction sites or certain
industries is at greater risk of injury. This fact is observed annually in the
statistics of work accidents and their causes. This inexperience includes
ignoring certain dangers if they have not received extensive training, poor
work safety practices, and poor skills in the profession, which substantially
increases the likelihood of suffering a workplace accident.
Job factors
Now we are talking about factors that are the direct
responsibility of the company and the environment that is imposed on the
worker. First of all, we can mention the consequences of inefficient leadership
in which the correct instructions are not given or the tasks carried out by
workers are not sufficiently supervised as a preventive measure against
workplace accidents.
Likewise, among the factors of the work environment, we find
the correct maintenance of machinery, means of production and tools used in
work processes. At best, a machine failure can inflict a mere scratch on a
worker that will not require any time off, and at worst, poor machine
maintenance can lead to the death of a worker, either by electrocution,
crushing or entrapment.
Furthermore, it is the company's responsibility to train workers in occupational risk prevention with training programs specific to their jobs. This is how the company informs the workers about the risks that surround them, how to protect themselves and how to proceed in the event of a workplace accident.

Root cause analysis examples
If you only try to treat the symptoms, they will repeat
themselves over and over again. It is important to find the answer to the
following questions:
- Why did this unsafe act occur?
- Why did this unsafe condition appear?
- What went wrong in our system that allowed that unsafe act or condition?
To solve or analyze a problem, we will need to perform a
root cause analysis and find out exactly what the cause is and how to fix the
problem. In this article, muniriyathse (safety zone) will define root cause
analysis, outline common techniques, and provide some examples.
What is root cause analysis?
The RCA assumes that it is much more effective to
systematically prevent and resolve underlying problems rather than just
treating symptoms.
Root cause analysis can be performed with a collection of
principles, techniques and methodologies that can be leveraged to identify the
root causes of an event or trend. By looking beyond superficial cause and
effect. RCA can show where processes or systems failed or caused a problem in
the first place.
When we analyze problems and root causes, it is important to
take a comprehensive and holistic approach. In addition to uncovering the root
cause, we must strive to provide context and information that will result in an
action or decision. Remember: a good analysis is an actionable analysis.
The 5 Why?
One of the most common techniques for performing root cause
of incident analysis is the 5 why approach. For each answer to a WHY question,
follow it with an additional, deeper “Okay, but WHY?”
Example: Let’s remember our concussion example. First, an
employee slips and falls in the workplace.
This is our first WHY.
Why 1: Why did the employee slip?
A: Because there was a spill on the floor.
Why 2: Why was there a spill on the floor?
A: Because a container with liquid was not properly sealed.
Why 3: Why was the container not properly sealed?
A: Because the lid was damaged.
Why 4: Why was the lid damaged?
A: Because it wasn't regularly checked during maintenance.
Why 5: Why wasn't it regularly checked during maintenance?
A: Because management decided there was no need to have a
maintenance plan in place.
Root cause of incident: Lack of a scheduled maintenance plan
for checking equipment for which senior management is accountable.
Tips for Conducting an Effective Root Cause Analysis
Ask questions to clarify the information so we can get
closer to the answers. The deeper we can dig and interrogate each potential
cause, the more likely we are to find a root cause. Once we believe we have
identified the root cause of the problem, we can ask even more questions: Why
are we sure this is the root cause rather than this? How can we fix this root
cause to prevent the problem from happening again?
Underlying causes of Occupational Health and Safety
incidents often involve deeper issues within an organization's systems or
practices. Some examples include:
Lack of Training: Insufficient training programs or failure
to provide ongoing education can result in employees being unaware of proper
safety procedures.
Poor Ergonomics: Workspaces that do not consider ergonomic
factors may contribute to musculoskeletal issues and injuries among workers.
Conclusion
The "root cause" of an incident refers to the
fundamental, underlying reason why it happened. It's the essential factor or
combination of factors that set off the chain of events leading to the
incident, as opposed to just the immediate symptoms or trigger points. Understanding
the root cause is crucial because it allows you to:
- Prevent similar incidents in the future: By addressing the root cause, you can eliminate the underlying problem and stop it from triggering future incidents.
- Implement effective corrective actions: Focusing on the root cause ensures your solutions target the source of the problem, not just superficial fixes that might temporarily mask the issue.
- Improve overall system reliability: Identifying and addressing root causes strengthens your systems and processes, making them less prone to failures and interruptions.
Here are some additional things to keep in mind about root
causes:
- They are often deeper than you might think: Don't settle for the first obvious explanation. Dig deeper and ask "why" questions repeatedly to uncover the underlying factors.
- They can be complex: Multiple factors can contribute to an incident, so be prepared for a nuanced analysis that takes all relevant aspects into account.
- Finding them takes effort: Root cause analysis can be a challenging process, requiring careful investigation, data analysis, and critical thinking.
