Revised 4/30/2020 with update regarding EHRS tracing of Suspect/Confirmed Penn cases


This guidance provides recommendations on the cleaning and disinfection of rooms, areas, and labs of those with suspected or with probable and confirmed COVID-19 have visited. It is aimed at limiting the survival of novel coronavirus in key environments. These recommendations will be updated if additional information becomes available. These recommendations are adapted from the CDC guidelines focused on community, non-healthcare facilities (e.g., schools, institutions of higher education, offices, daycare centers and businesses) 

Suspected COVID-19

Notify all lab members and other individuals who may have had close contact with the employee.  Begin enhanced health monitoring including temperature screening each morning.  Follow isolation protocols if you become ill.

General Cleaning:

Notify Housekeeping for enhanced cleaning outside the laboratory.  Cleaning should include areas used by the ill lab worker including all restrooms, interior high contact surfaces such as door handles/knobs/crashbars, light switches, elevators, bottle fill stations and building entrances.

Lab Cleaning:

Lab workers should clean all lab surfaces with products that are EPA-approved for use against the virus that causes COVID-19. Wear gloves when you clean.  A list of products is available here.  You may also use alcohol to clean surfaces.  Exercise caution as even 70% ethanol is flammable and can be ignited.  Best practice is to saturate a wipe and apply to a surface rather than directly spraying the surface if ignition sources are nearby. Follow the manufacturer’s instructions for all cleaning and disinfection products (e.g., concentration, application method and contact time).  Clean handles for sinks, DI water systems, cabinets (including acid and flammable liquid), fume hood sashes, lab benches, phones, freezer and incubator doors.

Place employee lab coat in plastic bag and have it laundered.  Disinfect employee safety glasses, face shields, keyboards and books (including lab notebooks) used by the employee.

Confirmed COVID-19

As of April 20 EHRS is performing critical contact tracing for the University of Pennsylvania.  Report all Suspected/Probable/Confirmed cases to EHRS 215-898-4453 (24 hours) 

Supervisor should notify EHRS.

Restrict access to lab until FRES (Faramarz Vakili) arranges for enhanced cleaning of lab and areas outside the lab.
