The good news is, there are many inexpensive things you can do to help donors and staff members feel safer in your center, thereby maintaining or even increasing production.
Negative air pressure, hard-ducted air returns, air returns in every room, supply diffusers on outside walls, and strict high CFM standards can keep virus particles out of your centers.
If you have Stough-build centers, you are already benefitting from all these healthy-building choices. If you don’t, we can help.
We are also currently recommending centers maintain a C02 measurement of 600 ppm or lower to ensure you are circulating air enough to remove COVID aerosols.
To attain a C02 level of 600 ppm, you may need to adjust your mechanical ventilation system to pump in more outside air more often.
You can purchase a C02 monitor for about $100.
We are exploring whether air filters in the ductwork could be a good solution for further keeping indoor air safe. In the meantime, you may want to consider portable air filters.
A recent Harvard Medical School study has shown that maintaining a relative humidity of 40-60 percent was associated with lower rates of infection and inflammatory disease. With this level of humidity, infectious aerosols quickly settle out of the air. Inhaled viruses are less infectious in this RH range, and higher humidity also helps the immune system fight infections.
This small change could make a big difference.Back To Top
Because of COVID, we are currently re-evaluating every surface typically used in a Stough-built center. Surfaces in a plasma center should meet the following criteria:
We addressed cleanable surfaces in a previous blog, The Magic of Cleanable Finishes, written before the onset of COVID-19. Here are some key considerations:
Instead of drywall walls, we recommend Type II vinyl wallcoverings (medium to heavy-duty) that are durable and made for high-traffic areas. They should be washable/scrubbable, have a high breaking strength, low crocking (tendency to give off color when rubbed), be stain-resistant, have a high coating adhesion, and high cold crack resistance.
Wallcoverings should also be smooth for cleanability. You don’t want anything with texture that could hold in blood, bacteria and viruses.
We use vinyl sheet goods, which have fewer seams for blood, bacteria and viruses to penetrate. This durable type of flooring is also warm and pleasing to look at, which helps improve the overall morale of patients and workers.
In our phlebotomy wards, we use a BioSpec rolled cove base. This is achieved by running the flooring up the wall. It keeps dirt and doesn’t allow liquids or particles to penetrate beneath it, preventing the growth of bacteria.
As with preferred ventilation for stopping COVID, your Stough building already incorporates these preferred options.Back To Top
To prevent the spread of infection in waiting rooms, many plasma centers are having donors wait in their cars for their turn to donate plasma. This practice has several problems:
Some solutions may include: expanding waiting areas to allow for social distancing, adding partitions or drapes between seats, and offering hands-free hand sanitizing in waiting areas.Back To Top
You may want to consider replacing exterior and waiting room doors with automatic doors that do not require touching a handle or doorknob.
While there is a substantial cost involved, this change will reduce the need to constantly clean door handles/knobs.Back To Top
Recent studies are showing that COVID-19 is likely spread through fecal matter–aerosolized when one flushes the toilet. These “bioaerosols” spread and stay until they settle on surfaces, are removed through ventilation or filtration, or someone breathes them in.
What you can do:
You may also want to look at hands-free-flush toilets, hands-free faucets, and sheet vs. roll toilet paper (toilet paper is the most contaminated item in the bathroom). Putting partitions between toilets in the men’s room is another idea, along with making stall walls reach farther toward ceiling and floor.Back To Top

To streamline delivery and control costs, we take a prototype approach when possible, engage local civil engineering consultants for each project, and establish a working relationship with the local governing authority.
