It is hard to evaluate that right now.
We have had great difficulty obtaining personal protective equipment due to the shortage of these products, whether it be surgical masks, goggles or hand-washing equipment. Another reason this is difficult to assess is that we do not know how long these measures will need to be maintained. If we did, we would be able to estimate how much money we would need to respond. This situation is extraordinary and was not anticipated by organizations when they established their costs of doing business. The costs are therefore difficult to assess, but they are still significant.
If we want to modify vehicles with equipment that is supposed to improve safety—which has not really been proven effective—we need the materials to do it, which is difficult. And there are other significant costs associated with purchasing such equipment.
