Instructions of wearing FFP-masks

A general obligation to wear a mask is intended to slow down the rate at which the coronavirus spreads. In this way, other people can be protected from infection through droplet infection, as well as themselves.

Since mid-April 2020, there have been occupational health and safety standards issued by the Federal Ministry of Labor and Social Affairs. Two clear principles apply here:
1. Irrespective of the company's concept of measures, in cases of doubt where the minimum distance cannot be safely maintained, mouth-nose coverings should be provided and worn.
2. Persons with respiratory symptoms should generally not be on the company premises.

The Federal Institute for Occupational Safety and Health (BauA) has also set up a topic page on this subject.

Since 18.01.2021, an extended regulation on the wearing of FFP2 masks has been in force in Bavaria. This new decision summarizes that in the Free State of Bavaria it is mandatory to wear a FFP2 mask in public transport and retail.

The FFP2 mask is the optimal mask for the Corona pandemic. Due to the increased filter performance, not only is external protection ensured, but also self-protection when used correctly. Keller & Kalmbach strongly recommends the use of the FFP2 mask.

How often can an FFP2 mask be used?

A total of 8 hours should not be exceeded. The wearing time can also be added up if the mask is only used for shopping or public transport, for example, and is removed in between. The FFP2 mask is electrically charged, which improves the filtering effect. After use for longer than 8 hours, this charge may wear off and therefore no longer provide the necessary protection.

Can another mask be worn instead of an FFP2 mask?
Yes, this is allowed. However, care must be taken to ensure that these have a comparable protective effect, such as masks marked KN 95 and N 95.

How long may an FFP2 mask be worn at a time?

There is no concrete specification for this. However, there are occupational health and safety recommendations which are also followed by the Robert Koch Institute. The recommended wearing time is a maximum of 75 minutes at a time, followed by a 30-minute break.

Can the FFP2 masks be reprocessed or reused?
In the current situation, we do not recommend reprocessing or reuse.

These masks are used in working areas where there are harmful substances in the air. The masks keep out pollutants and viruses. They are considered to be the subject of personal protective equipment within the scope of occupational health and safety. FFP1, FFP2 and FFP3 masks are available, depending on filter performance.

As a mechanical barrier or brake for the transmission of breath droplets or saliva when breathing, coughing or sneezing, these masks are manufactured from commercially available materials in a wide variety of variations. 

The mouth-nose-masks are optically similar to the medical oronasal protection mask \(surgical mask\) but cannot be used in the medical field. Ideally, test reports from certified institutes are available for these masks. The specified filter performance should be greater than 90%. They can prevent the spread of droplets from the wearer and are primarily intended to protect the person wearing them.

KN95 is the name of a filtering half-mask that is marketable in China, Test standard GB2626-2006. The testing by state-certified Chinese testing centres is recognised by German authorities. This means that KN95 filtering masks can also be used in the medical/nursing sector.

Why are certificates so important?

Regardless of the company's concept of measures, according to the occupational safety standards of the Federal Ministry of Labour and Social Affairs, mouth and nose covers should be provided and worn in cases of doubt where the minimum distance cannot be safely maintained. The situation on the procurement market remains tense, and the risk of fraud is unfortunately very high. Often it concerns goods with false or missing certificates.
