Analysis of integrity of selected brands of coveralls and N-95 masks following multiple cycles of VHP exposure by liquid permeation test. Using water droplets of different volume, we investigated the change in permeability status of coveralls arising due to multiple cycles of VHP exposure. a, b Coveralls. c, d N-95 masks. 50 µL (a, c) and 100 µL (b, d) water was seeded on selected brands of coveralls and N-95 masks. Hard non-permeable surface (petri plate surface) was used as control for evaporation. The time taken for water droplet disappearance from PPE surfaces was normalized against droplet evaporation time from the petri dish (i.e. natural evaporation time). Time comparable to or slightly higher to evaporation control in tested coveralls and N-95 masks indicate no permeation associated loss of droplet indicating integrity of PPE. Lack of availability of some suits limited a full range of analysis on some datasets. [Statistical evaluation done by Two-way ANOVA, with Bonferroni post-test correction]. Clearly, VHP treatment did not result into significant changes in permeability of PPE
