Evaluation of hydrogen peroxide and ozone residue levels on N95 masks following chemical decontamination.

ABSTRACT:

Background

Hydrogen peroxide and ozone have been used as chemical decontamination agents for N95 masks during supply shortages. If left behind on the masks, the residues of both chemicals represent a potential health hazard by skin contact and respiratory exposure.

Aim

Characterization of hydrogen peroxide and ozone residues on mask surfaces after chemical decontamination.

Methods

Various N95 masks were decontaminated using two commercial systems employing either aerosol spray or vaporization of hydrogen peroxide in the presence of ozone. Following the decontamination, the masks were aired out to eliminate moisture and potential chemical residues. The residual hydrogen peroxide and ozone were monitored in the gas phase above the mask surface, and hydrogen peroxide res
