What is work safety and what is it for?

Occupational safety is a science that analyzes risk factors and causes of accidents during a worker’s exercise. In addition, it also defines preventive measures in the work environment.

What are the types of occupational hazards?

This definition is made according to its nature: physical, chemical, biological, ergonomic, and accidents. Are we going to better understand each one of them?


Physical risks refer to noise, vibration, abnormal pressure, humidity, among others.

In this sense, it is necessary to evaluate effective preventive measures, such as the use of PPE, exposure for a limited time, alternating shifts, etc. 


In relation to this type of risk, they involve dust, gases, vapors, substances, and chemical products in general.

After all, above all, this type of action will disinfect the environment, reducing the risk of contagion.


Ergonomic risks include physical exertion, carrying weight, poor posture, excessive pace.

Therefore, for this item, the employer must provide equipment suitable for the worker’s routine. 

In addition, in cases of inadequate requirements on the part of the company, the employee must report irregularities to Organs competent bodies.


Accidents can be caused by defective equipment, electricity, fire hazard, among others.

Each company must assess the environment and activity in order to take all possible measures to prevent accidents. This involves everything from the infrastructure to the continuous specialization of employees.

  • Planning work systems that anticipate risks;
  • Accidents prevention;
  • Investigation of causes and relationships in occupational or occupational diseases;
  • Inspections of working conditions ;

  • Among others.

What does an occupational safety technician do?

The occupational safety technician is responsible for all practices that involve the prevention of accidents and the protection of employees.

Thus, its performance comprises the analysis of the state of the company, considering the environment, infrastructure, and risks involved.

From that, he needs to elaborate plans that improve the workers’ routine. Among its attributions are also the tasks of structuring training and promoting the education of the entire team.
