Research on Microclimate Cooling in protective clothing is not a new topic. Yet we are not able to provide cooling to the health care workers. In this research contribution I try to give some information on where the problems are.

As long as PPE with sufficient cooling and safety are not available in the required quantities, cooling the workers is a complex task without a simple solution.
Employ specialists who monitor the thermal situation, help in improving the environment

A system of plastic curtains closes the space around a worker in PPE. As soon as person enters the space is filled with cool air and vented to improve heat transfer. The system work due to conductive cooling as well as by radiative cooling from the s

A list of supposed causes for the outbreak together with supposed major reasons why it does not stop. Whenever possible together with references to prove. I will adjust them, if needed.

Hi A Pi,

thanks for updating the post. I still wait for a quantitative description of the problem (How hot is the environment really, how active are the workers) and on experiments. I am quite sure, that someone makes this, but all people I asked do not know about this. So we will probably learn this in a few month.

And to do measurements ourself to evaluate and improve is difficult without a climate chamber and other tools. And again, I would not even know how hot I shall make the climate for the tests. The resources of USAID appear so limited, that they have no time to give us feedback by experts. And if I try to help you, this takes even more from the limited time, I have for making and proposing own ideas. So, I am sorry, but I cannot help you as much as I would like to.

I will let you know, if I know more.

With kind regards,
Rainer

Hi Nathan,

I agree with you. Face masks where the workers are easily visible are important. Did you already approach the problem of filtering the breathed air under a full face mask?

With kind regards,

Hi A Pi, I will try to assess it. There should be some cooling effect. But this clothing may also increase isolation if it is not cold anymore. With kind regards, Rainer
