Abstract
We conducted a laboratory simulation to evaluate the contamination of environmental surfaces when using wipe vs spray methods of personal protective equipment (PPE) decontamination. We did not observe any environmental contamination with the bacteriophage MS-2 when bleach solution spray or wipes were used for PPE disinfection.

We conducted a laboratory simulation to evaluate the contamination of environmental surfaces when using wipe vs spray methods of protective equipment (PPE) decontamination
Postdecontamination, MS-2 was not detected on any surrounding environmental surface in quantitative or qualitative cultures in all 20 experiments
We did not observe any environmental contamination of nearby surfaces with bacteriophage MS-2, a human virus surrogate, when bleach solution spray or wipes were used for PPE disinfection
Summary
We conducted a laboratory simulation to evaluate the contamination of environmental surfaces when using wipe vs spray methods of personal protective equipment (PPE) decontamination. We did not observe any environmental contamination with the bacteriophage MS-2 when bleach solution spray or wipes were used for PPE disinfection. During the 2014 Ebola outbreak in West Africa, personal protective equipment (PPE) and the environment were frequently decontaminated using disinfectant (usually bleach) spray solutions [1, 2]. In the United States, the Centers for Disease Control and Prevention primarily recommended disinfectant wipes for healthcare worker PPE decontamination [3] due to occupational health concerns of bleach spray exposure such as adverse respiratory effects [4] and potential falls due to slippery conditions created by spraying. We conducted a laboratory simulation to evaluate the contamination of environmental surfaces when using wipe vs spray methods of PPE decontamination. A secondary objective was to assess reduction in PPE viral contamination with the 2 methods
