Occupational Health: understand what is a work accident, occupational diseases and the most recent updates on mental health in the workplace

For many years, when people talked about work accidents, most imagined only serious situations, such as falls, cuts, burns, or accidents involving machinery. But occupational medicine has evolved greatly in recent years, and today there is a broader understanding of how the work environment can affect people's physical and emotional health.

The most recent updates to Brazilian occupational health standards reinforced exactly this: worker health does not involve only preventing physical accidents, but also preventing mental illness, emotional overload, and unhealthy work environments.

In practice, this means that situations such as excessive pressure, abusive targets, exhausting work hours, moral harassment, and psychological strain have received even more attention within workplace safety and health standards.

What is considered a work accident?

A work accident is any situation related to professional activity that causes injury, loss of functional capacity, absence from work, or harm to the person's health.

This includes sudden accidents, diseases developed over time, and even some situations that occur on the commute between home and work.

Typical accident

It is the accident that happens during the performance of professional duties.

Clinical example

A construction worker falls from a ladder while performing maintenance at height and sustains a fracture in the arm.

In this case, there is a direct relationship between the work performed and the accident that occurred.

This category also includes:

• cuts from machinery;

• burns;

• electrical accidents;

• accidents involving biological material;

• crushing injuries;

• acute poisoning;

• falls in the work environment.

Commute accident

It is the accident that happens on the route between home and work or on the return home.

Clinical example

A nursing technician has a motorcycle accident while heading to her shift and sustains a fracture in the leg.

Even though it occurred outside the hospital, the case can be recognized as a commute accident.

However, it is important to understand that each situation needs to be analyzed individually. Deviations for personal interests or interruptions unrelated to work can change this classification.

Occupational disease: when the problem appears gradually

Not all work-related illness happens suddenly.

Many diseases develop slowly after months or years of repetitive exposure, constant physical effort, excessive emotional pressure, repetitive movements, intense noise, or inadequate environments.

These conditions are called occupational diseases.

Clinical example

An administrative assistant spends years working long periods typing without adequate breaks. Over time, she begins to feel pain in her wrists, tingling, and loss of strength in her hands.

After medical evaluation, she receives a diagnosis of work-related tendinitis.

Other common examples include:

• repetitive strain injuries;

• chronic back pain;

• hearing loss from excessive noise;

• respiratory diseases caused by dust or chemical products;

• burnout syndrome;

• anxiety related to the work environment.

What changed recently in worker health standards?

The most recent updates to NR-1, the standard that addresses occupational risk management in Brazil, expanded companies' responsibility regarding workers' mental health.

Now, psychosocial factors have been officially included in the prevention of occupational risks. This means that situations such as:

• moral harassment;

• excessive psychological pressure;

• incompatible targets;

• exhausting work hours;

• emotional overload;

• toxic work environments;

must be observed, identified, and prevented by companies.

This update represents an important change because it recognizes that mental health is also part of occupational health.

Today there is greater understanding that emotional suffering related to work should not be seen merely as "weakness" or an individual problem, but also as a consequence of the professional conditions to which the person is exposed.

The Schilling classification explained in simple terms

In occupational medicine, there is a classification widely used to understand the relationship between disease and professional activity: the Schilling Classification.

Although the name is technical, the idea is simple.

It divides diseases into three groups.

Group I: work is the main cause of the disease

In this group, professional activity is directly responsible for the problem.

Example

A worker exposed to intense noise daily develops hearing loss.

Without that constant exposure, the disease would probably not occur.

Group II: work contributes to the appearance of the disease

Here, the disease can occur in any person, but work greatly increases the risk.

Example

A person who works carrying weight daily develops lumbar disc herniation.

Work is not the only possible cause, but it contributed significantly to the problem.

Group III: work worsens a pre-existing condition

In this case, work worsens a disease that the person already had.

Example

A person with pre-existing anxiety begins working in an extremely stressful environment, with excessive pressure and intense work hours, and begins to experience frequent crises and difficulty maintaining their routine.

Here, the work environment acts as an aggravating factor.

What is generally not considered a work accident?

Not every illness or accident that occurs during work hours is automatically considered a work accident.

Some situations may not have proven occupational connection.

Examples

• diseases with no connection to the function performed;

• accidents caused exclusively by personal issues;

• pre-existing conditions with no connection to or worsening by work;

• situations outside the professional context.

Each case must be analyzed individually through medical evaluation and proper documentation.

What to do when a work accident happens?

Many people are confused after an accident or when they begin to show symptoms related to work.

Some measures are important:

• seek medical care as quickly as possible;

• explain in detail how everything happened;

• keep exams and documents;

• inform the company;

• observe persistent symptoms even after apparently minor accidents;

• seek help when experiencing frequent pain, physical limitations, or emotional suffering related to work.

The earlier the evaluation, the greater the chances of preventing complications.

How can the doctor help?

The physician's role goes far beyond treating an injury.

Proper evaluation helps identify whether there is a relationship between the health problem and the professional activity performed.

Beyond diagnosis, follow-up care can assist with:

• physical recovery;

• pain control;

• functional rehabilitation;

• guidance on return to work;

• prevention of sequelae;

• early identification of occupational diseases;

• care for mental health related to the work environment.

In many cases, recognizing the problem early prevents significant worsening and improves quality of life.

Worker health is also prevention

Taking care of occupational health does not mean acting only after an accident.

Safe environments, adequate breaks, correct ergonomics, protective equipment, and attention to mental health are part of modern prevention in occupational medicine.

Recent updates to Brazilian standards reinforce exactly this: protecting worker health involves caring for both physical and emotional well-being.
