Industrial ventilation is synonymous with safety at work. Understand

Industrial ventilation x safety at work

Industrial environments are places saturated with airborne contaminants from processes carried out in these same environments.

Factories and industries deal with raw materials from different origins, submitting them to processes and handling for the transformation of these materials into new and different products.

But it is important to keep in mind that any industrial process results in the generation of different types of waste and rejects: solids, liquids, waste suspended in the air such as dust particles, aerosols, among others. And it is the role of the generating companies to carry out the treatment and correct disposal of these by-products, in a way that does not harm the environment.

In this article we will talk about the emission of air contaminants, and we will see what is the best option for industries to solve this problem.

Safety in work environments

Pharmaceutical, food, chemical, textile industries, among many others, are some of the places that tend to be impregnated with odors, gases, dust particles, in addition to other possible contaminants such as mites, viruses and bacteria that use these particles to circulate and propagate through of air through the environments.

Industrial pollution is something serious that can affect the health of local workers and can cause contamination of products, so it is also a very relevant issue for companies. Because it can generate diseases, possible contamination to final consumers, fines, etc.

It is necessary for companies to always comply with existing norms and rules (for each branch and sector) thus minimizing risks to their employees, damage to the environment and avoiding contamination of products.

The use of PPE, for example, is a way to reduce the risk of contamination and accidents at work. After all, without adequate protection, employees are more exposed when in high-risk environments.

Indoor air quality in environments such as factories needs to be high and safe. People who work in these places cannot breathe air loaded with contaminants that are harmful to their health. Chemicals, toxic or non-toxic, are harmful to the respiratory system and the body in general. So companies need a system that adequately fulfills the function of renewing the ambient air. For this is also a way to protect employees from the risks of contamination.

Without the exchange and filtering of air in industrial environments, the air is impregnated with contaminants and can certainly become a danger for those who remain in the place.

Work Safety Standards

The work safety standards aim precisely to protect the health of people in these places. They are a set of rules applicable to each situation, and whose purpose is to make the workplace a less unhealthy and safer place for everyone.

NR15, for example, is one of the Norms that talks about safety at work in unhealthy environments. Within this standard, some items deal with matters that are relevant to air treatment. See the link below.

Industrial Ventilation System

Industrial ventilation performs the renewal of air, promoting…

Comfort and Safety!

Air that has been taken from an external environment is deposited on site. Meanwhile, indoor air is guided out of the room by a duct system, and is treated before being discharged. Of course, this is a simple way of describing the ventilation system.

This system carries out the continuous process of renewal of this element, prevents contaminated air from remaining in the place and brings clean and renewed air to the enclosure.

But industrial ventilation by itself does not perform any act of refrigeration, but by exchanging indoor air for outdoor air it is possible to achieve a milder temperature. And generally this system is usually used in conjunction with the air conditioning system.

The ventilation system also contributes by attenuating the heat caused by the heating of industrial machines. This process takes place through air renewal, when the hot air is removed and new air is injected from an external environment, the heat from the machines is prevented from propagating through the place.

Benefits of the Industrial Ventilation System

Air circulation
Clean and renewed air through filtration
Aid in temperature control / Greater thermal comfort
Health and safety in the work environment (by removing contaminated air)

Some components of the Ventilation system

Ventilators
ducts
dampers
Filter
Streamers
Humidifier / Dehumidifier

Air Filters

The performance of the air treatment in the ventilation system is done from the filters used.

Air filters retain gases, dust particles, odors, bacteria and other types of contaminants, leaving the environment free of contaminants.

Filters must be used to capture external air, treating the air before depositing it in the environment (depending on the industrial process carried out, the air needs an extreme degree of purity, so this filtering is essential).

But also in the act of dumping into the outside atmosphere, the air needs to be filtered. After all, it is the role of the industries to carry out the correct treatment of their tailings and only then carry out the disposal.

Filter Change

Changing the air filters is another extremely important factor. Saturated filters, in addition to preventing the system from working efficiently, further propagates contaminants through the air.
