I've been saying this exact thing since March 2020
Even with a full biosuit getting out of it without cross contamination and exposure is difficult. We used to train for this by taking new recruits getting them into the suits then coating the outside of them with karo syrup dyed bright blue the recruits task was to remove the suit in.decon without so much as a speck of sticky blue anywhere on their body. The success rate for the first try was less than 40% this was for NBC rated soldier’s who would get 25 weeks of training to accomplish the mission in a NBC challenged environment. The average civilian has a zero.percent probability of not contaminating themselves even in a full sealed biosuit with a full SCBA breathing set up. M40 masks with NATO canister filters are rated for NBC and will filter viri in addition to.chemical agents and.fall out particles down to submicron levels.
