Instructions for the wearing of mouth-nose-coverings

According to the current state of knowledge, the wearing of mouth-nose-coverings, among other measures, can help to further contain the spread of the novel coronavirus SARS-CoV-2 - even when there are no signs of the disease. The corona virus SARS CoV-2, which triggers the disease COVID-19, is released into the environment as an aerosol via the air we breathe when we speak, cough or sneeze. It is therefore obvious to wear a mouth-nose cover as a mechanical barrier or brake.

Since mid-April, occupational health and safety standards have been in place from the Federal Ministry of Labour and Social Affairs. Two clear principles apply here:

1. Regardless of the concept of measures at the workplace, in cases of doubt, where the minimum distance cannot be safely maintained, mouth-nose covers should be provided and worn.
2. Persons with respiratory symptoms should generally not stay on the company premises.

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

Should respiratory masks be worn in factories and offices?

A mouth-nose cover makes sense wherever the distance regulations cannot be consistently observed. It helps to protect employees and customers. However, respiratory masks should be reserved for medical personnel.

What masks are available and how do they differ? 

In addition to the often self-stitched community masks, there are medical protective masks, so-called surgical masks (operating masks) and filtering half masks, which originally come from the occupational safety sector. A comparison of the individual mask types, their standardization and certificates, as well as whether external and/or internal protection is provided, is shown in the following overview.

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.
