FAQ – Frequently Asked Questions Regarding Corona

On this page, we would like to inform you about the current measures at Chemnitz University of Technology regarding the coronavirus. The development of the current situation is dynamic. We therefore ask you to always check the homepage of Chemnitz University of Technology and this FAQ page from the Office for Security at Work and Environment Protection (BfAU).

Here you will find a list of numerous questions and answers as well as contact persons on the topic. The page is continuously supplemented and updated.

Information on the current measures at Chemnitz University of Technology can also be found in the Open Letters from the President regarding the corona virus (SARS-CoV-2).

Current Information on coronavirus

Students of the TU Chemnitz should contact the staff of Department 1 (Academic and Legal Affairs) for questions regarding the coronavirus, and Department 2 (Human Resources) is available for employees. In addition, Ms Monique Kautz (phone +49 371 531-34254, e-mail: ) is your contact person in the Office for Security at Work and Environment Protection (BfAU) at Chemnitz University of Technology.

Maximum Usage Time for Medical Masks

Mouth-nose protection or medical masks are disposable products. As the wearing time increases, the mask becomes damp. If it becomes soaked, it must be changed, at the latest every working day. The recommended usage time limit (uninterrupted wearing) for medical face masks is three hours for light work and two hours for medium work, followed by a 30-minute break.

Maximum Usage Time for FFP2 masks

The maximum continuous usage time for an FFP2 mask is 75 minutes for moderately heavy physical work; for light physical work such as office work or in-person examinations, the maximum usage time can be extended by a factor of 1.5 to 112 minutes. This must be followed by a minimum recovery period of 30 minutes (without FFP2 mask). FFP2 masks are suitable for a work shift of eight hours with a maximum of five uses. If an FFP2 mask becomes damp, it may also have to be disposed of prematurely.

In operational practice, it is often possible to remove the mask for a short time, depending on the situation, without endangering oneself or others. In these cases, adequate recovery time is possible.

Storage and Disposal of Medical Masks and FFP2 Masks

Masks should be stored according to the manufacturer's instructions. The original packaging should be used for storage and transport. Alternatively, a clean plastic bag with a zip closure may be used.

Contaminated/soiled, damaged, or used masks must be disposed of in the residual waste (Restmüll) after use.

Additional Information

Additional information on the subject of mask-wearing can also be found on the websites of

The basis for wearing FFP2 masks is DGUV regulation 112-190 on the use of respiratory protective equipment. The German Social Accident Insurance’s publication can be found using the following link (German).

Since January 20, 2023, there has been an urgent recommendation to wear medical or FFP2 masks or masks of a comparable standard (e.g. KN95 or N95) in all university buildings, specifically in all indoor rooms such as staircases, corridors and other shared rooms, as well as in all face-to-face (teaching) events and examinations. If required, students receive masks from teachers, examiners or supervisors before the start of the respective on-site course or examination. Employees are also provided with appropriate masks on request. Care must be taken to ensure that the masks are properly handled (put on and off, do not move during wearing, recommendations for wearing time).

For information on correct handling, please refer to the question: What should I pay attention to while wearing a medical or FFP2 mask?

Work protection, work medicine

  1. It is strongly recommended to keep a sufficient distance (at least 1.5 metres) from other people, especially indoors. Direct physical contact (e.g. shaking hands or hugging) should be avoided.
  2. Keep as much distance as possible when coughing or sneezing. Cough and sneeze into the crook of your arm or into a paper handkerchief, which you dispose of afterwards.
  3. Wash your hands regularly and thoroughly with soap and water for at least 30 seconds.
  4. Keep your hands away from your face, avoid touching your mouth, eyes, or nose with your hands.
  5. If possible, do not share items such as work materials with other people. For post processing etc. it is recommended to wear (disposable) gloves.
  6. If possible, clean or disinfect your workplace, especially when you leave or when you start work if you have to share it with other people (e.g. keyboards). However, if possible, try to carry out your work exclusively at individual workplaces.
  7. Rooms should be ventilated regularly (every 20 minutes, or more frequently depending on thesize of the window). Ventilation systems (RLT) should continue to be operated if they have suitable filters or supply a high proportion of fresh air, as the risk of virus transmission is consideredto be low. Air conditioning systems should not be switched off during operating or working hours, as this can lead to an increase in the concentration of viruses in the room air and thus to anincrease in the risk of infection. If air handling units are not operated permanently, their operatingtimes should be extended before and after the time the rooms are used.
  8. Wear a medical mask or an FFP2 mask or a mask of equivalent standard (e. g. KN95 or N95) in publicly accessible premises where the minimum distance of 1.5 metres is not possible. Appropriate masks are provided to employees by the university.

The confirmation shall be worded as follows:

“Confirmation on the duration and exercise of the activity in mobile work for Mr/Ms/Mrs …

From … to … [date] no workstation/no workstation on an average of … [number] days per week* was available to the employee at the premises of TU Chemnitz due to the protective measures to contain the coronavirus (SARS-CoV-2).”
* due to possible need for a differentiated assessment over time, please delete as appropriate

A copy of the confirmation should be sent to the Human Resources Department for the personal file.

The following requirements for the recognition of a home office must be observed:
The tax office recognises a home office in two cases:

  • If no other workplace is available for the professional activity, costs for the home office can be assessed up to 1,250 EUR.
  • If the home office is the centre of the entire professional activity, the expenses for the home office can be taken into account in unlimited amounts.

Spatial requirements:
It must be a separate room. Apartment and home office must be physically separated from each other. A desk in the bedroom or living room does not make these rooms into a home office in the fiscal sense. Even a room that serves as a guest room in addition to its function as a home office is not recognised by the tax office as a home office. The Federal Fiscal Court (BFH) decided in 2016 that expenses for “a room that is integrated into the domestic sphere and a not inconsiderable part of its area is also used privately” are not considered as business expenses or income-related expenses (Ref.: X R 32/11).

Requirements time-wise:

If the employee works exclusively from home and no other workplace is available to him at the employer's, this is the center of the professional activity. If the employee works qualitatively in the same way in the home office and in the employer's office, it is decisive for the tax assessment where the predominant working time is performed. If the employer and the employee have agreed that the employee will work in the home office on one or two days, the employee will quantitatively work predominantly in the employer's office. In this case, no unlimited deduction of the expenses for the home office attributable to the period of the agreement can be considered. Rather, the employee may claim a deduction of up to EUR 1,250 at the most if the employee does not have a workplace at the employer's for reasons of infection protection at least on the days concerned.

If these requirements are not met, a home office cannot be claimed under tax law. In these cases, the only option is to claim the new home office allowance. This was introduced with the Annual Tax Act 2020. This allows taxpayers to claim a home office even if they voluntarily decided to work from home during the Corona pandemic or did not visit the workplace for health protection reasons on the orders of their employer.

The home office per diem is explicitly available even if no separate workroom is available, but work is done from the kitchen or living room.

This covers the following costs:

  • pro rata rental costs
  • costs for water, electricity, and heating incurred as a result of the professional activity,
  • pro rata cleaning costs,
  • pro rata building depreciation (AfA), if applicable.

These costs are not covered by the home office flat rate, but can be additionally declared as income-related expenses in the tax return:

  • Work equipment,
  • Telecommunication expenses (work-related costs for landline telephone, cell phone/smartphone, Internet, fax, if applicable).

The home office allowance exists for the years 2020, 2021 and 2022 in the form that the tax office recognises a lump sum of five euros for each day on which work was exclusively done from home during the Corona pandemic. However, the amount is capped, i.e. more than 600 euros may not be entered.

From 2023, the so-called home office allowance is no longer limited in time and can be claimed up to € 1,230.00 (basic calculation: € 6 per day).

Internal university activities and life at the university

The University Library is open to users from Monday to Saturday from 9:00 a.m. to to 10:00 p.m (where on weekdays from 7:00 p.m. and on Saturdays from noon only the security staff is on site). Users are requested to observe the recommendations in the hygiene concept of Chemnitz University of Technology.

Users can independently search for free, unlocked workstations and use them during the building opening hours. The cleaning frequency of workstations has been increased; freshly cleaned workstations are marked accordingly. The free-hand stocks are also available.

The URZ training pools are released at all known locations for independent use by students in compliance with the hygiene and protection regulations. No pre-registration is required for this. Independent compliance with the test recommendation and check-in via Corona-Warn-App are strongly recommended. The use of disposable gloves is also recommended. These will be provided.

In addition, laptops can be borrowed for a limited period of time (also outside the central examination period) for writing term papers, research papers and theses.

There will no longer be any restrictions on indoor university sports and health courses run by the Centre for Sports and Health Promotion (ZfSG) once normal operations resume in accordance with the 33rd Open Letter from the President regarding the Coronavirus (SARS-CoV-2) dated February 14, 2023.

For the use of the changing rooms, however, there is an urgent recommendation to wear a medical mask or FFP2 mask or a mask with a comparable standard according to the hygiene concept of the TU Chemnitz.

The outdoor sports facilities can be visited independently in the afternoons/evenings for individual sports by employees and students of Chemnitz University of Technology. Access is via the entrance to the sports hall (security guard).
