Protective half masks and their classification

There has been a lot of talk in recent days about protecting health from viruses. Problems with the availability of respirators have arisen across Europe. So it's time for some useful information about them.

What is a half mask anyway?

Simply put, it is a respiratory protection item. It differs from the mask in that it does not cover the eyes or the skin of the face. They absorb harmful particles in the air or filter them from various types of gases, viruses or microorganisms, preventing these harmful factors from reaching our respiratory tract and lungs. Although they may seem unnecessary, they protect in the long term - often various types of chemical compounds do not harm with a single contact. However, exposure to such substances for a long time can devastate the body step by step and lead to various serious diseases, including cancer. Depending on the class and application, respirators may differ in structure, appearance and properties.

How do we divide half masks?

The basic classification of half masks is the division according to the degree of protection, known as FFP (filtering face piece). There are three levels:

• FFP1 - the lowest grade that provides basic protection against non-fibrogenic (i.e., those that do not connect the connective tissue in the lungs) and non-toxic dusts. Mainly used in the stone, food and construction industries, works related to grinding, cutting and pollen. They do not protect against toxic substances or aerosols. They do not always block unpleasant odors and can sometimes cause irritation of the respiratory tract (especially when used improperly).
• FFP2 - half masks of this class provide protection against dust (solid and liquid), aerosols and smoke. They are mainly used in industries where smoke and fog are part of everyday life - e.g. in mining or metallurgy. They often have additional properties, such as reducing unpleasant odors.
• FFP3 - a class that provides protection such as FFP2, and additionally against carcinogens, radioactive agents, bacteria, viruses and fungi. They can filter up to 99% of harmful substances. They are most widely used in the broadly understood chemical industry.

Masks "not at once"

Reusable masks available on the market are usually purchased together with filters - preliminary, anti-dust or gas filters. Usually, manufacturers specify which filters will be compatible with the mask as well as with the work. When in doubt, it is always worth asking the seller.

The choice of mask depends on the working conditions. Check what you are exposed to. Ask a specialist what compounds can enter your body. Analyze your options and make the right choice.
