Many employees are exposed to contaminated air in the workplace, which may require measures to be taken. If it is necessary to protect the respiratory system, the risks must first be well defined. Contaminants can occur in various forms: dust particles, smoke, mist, gases and vapors. Combinations of contaminants are also possible and there may be oxygen displacement. View our different types of respiratory protection below.

Breathing protection is therefore necessary if there is a risk of entering harmful substances in the body via the respiratory system. These substances can be solid, liquid or gaseous. Protection is also necessary if the oxygen content of the surrounding air falls below the 19%. In the latter case, only the independent respiratory protection agents are usable. These are means whereby the fresh air is fed to the mask or the hood via a hose or air bottle. Our respiratory protection consists of a mask and a filter. There are different filters with function to stop or dust, gases or vapors and there are filters that both hold back: combination filters. The filters can already be installed in the masks.
The use of respiratory protective equipment during work is a considerable additional burden for the wearer. Before starting work, it is recommended to first look for alternative means before deciding to use respiratory protection. If the inhalation of, for example, dust and / or gas can not be prevented in any other way, workers must wear respiratory protection if there are harmful quantities of dust or gas / vapor. The effects of inhaling these substances or gas / vapors can remain relatively harmless, such as heavy sneezing, but can also have serious consequences such as persistent shortness of breath.
In order to determine which types of respiratory protection are necessary, the harmfulness of the substance, gas or vapor must first be determined. It is also important to know how much is released from this substance, gas or vapor. A measure of harmfulness is the limit value, the maximum accepted concentration of a substance in the air at the workplace. A number of limit values have been set by the government, these are the public, statutory limit values. If you stay below this limit, respiratory protection is not required unless otherwise indicated.
When choosing the respiratory protection, please note:
- What kind of pollution it is and the health risks associated with it;
- The limit value;
- The place where you work and the facilities that are located there;
- The timeframe in which the work must be carried out.
A simple disposable mask may be sufficient for protection, but a heavily polluted air may require a full face mask with breathing air. Always ensure that the fit and maintenance of the respiratory protective equipment are a prerequisite for safe use.
Dependent and independent respiratory protection
Respiratory protection can be distinguished in dependent respiratory protection and independent respiratory protection. Different types of respiratory protection fall under these categories:
- Dependent respiratory protection
- Independent respiratory protection
- Breathing air devices
- Supply hose fresh air cap
Independent respiratory protection can achieve a higher protection factor because the protection is not dependent on filters and the contaminated ambient air.
