MAINTENANCE INFORMATION DATE : April 2020 SUBJECT : MI20-09 SECTION : 00 GENERAL PREVOST VEHICLE DISINFECTION PROCEDURE First Release: 04-22-2020 APPLICATION Model VIN ALL PREVOST VEHICLES DESCRIPTION This Maintenance Information is intended to provide recommendations regarding vehicle disinfection during pandemic times. Following the recommendation listed in this document and proceeding to the disinfection of listed area of the vehicle will help to reduce the risks related to virus transmission to passengers and vehicle operators. IMPORTANT NOTICE Follow all CDC (Center for Disease Control and Prevention) policies regarding COVID19 prevention while working on the vehicle. -Practice social distancing while cleaning – 6 feet (2 meters) min. -Also wear appropriate PPE (personal Protection Equipment) Including but not limited to: Disposable gloves, gowns and face masks as well as eyes protection (shield or googles). Follow CDC recommendations Refer to CDC documentation: What Bus Transit Operators Need to Know About COVID-19. Check regularly for updated information. https://www.cdc.gov/coronavirus/2019-ncov/community/organizations/transit-maintenanceworker.html https://www.cdc.gov/coronavirus/2019-ncov/community/organizations/cleaningdisinfection.html#Cleaning https://www.cdc.gov/coronavirus/2019-ncov/hcp/ppestrategy/index.html?CDC_AA_refVal=https%3A%2F%2Fwww.cdc.gov%2Fcoronavirus%2F201 9-ncov%2Fhcp%2Fhealthcare-supply-ppe-index.html MI20-09/ Page 2 / 6 RECOMMENDED PRODUCTS AND USE PRODUCT TYPE Soap/Detergent USE Recommended for all soft (porous) surfaces like carpeted areas, seats and safety belts. Alcohol (70% min mixture) For small, hard (non-porous) surfaces like handrails, handles, belt buckles steering wheel and most of the driver’s controls & electronics. Can also be used on leather or vinyl seats. Disinfectant* For large area, hard (non-porous) surfaces like flooring, overhead compartment doors and interior trims. *Refer to page 18 of the APTA American Public Transportation Association - The COVID-19 Pandemic Public Transportation Responds: Safeguarding Riders and Employees for an approved list of disinfectants. - A DISINFECTANT SOLUTION CAN BE PREPARED BY MIXING 5 TABLESPOONS (1/3rd CUP) OF BLEACH WITH A GALLON OF WARM WATER. CAUTION - Do not add more than the recommended bleach concentration (1/3rd cup per gallon). Use of a higher concentration could damage some of the coach interior surfaces. - To be effective, a 60 seconds minimum (wet) contact time must be observed with the surface (at the specified bleach concentration). - Make sure surface has dried completely before boarding passengers (to minimize risk of passenger cloth discoloration and vapor exposure). When using commercially available cleaning products, follow the manufacturer’s recommendation for application, contact time, required personal protection equipment (PPE) and ventilation. Do not mix products containing bleach with ones containing ammonia. When diluting products, use the warmest possible water. Alcohol solution used to disinfect non-porous surfaces must contain at least 70% alcohol (as opposed to 60% for hand cleaning). Always use wet method to clean vehicles; avoid dry sweeping. It must be assumed that a virus can survive up to 72 hours on solid (non-porous) surfaces and may become airborne if on dust.MI20-09/ Page 3 / 6 UNDERSTANDING THE DIFFERENCE BETWEEN CLEANING AND DISINFECTING. According to the Center for Disease Control and Prevention (CDC), CLEANING refers to the removal of germs, dirt and impurities from surfaces. It does not kill germs, but by removing them it lowers their numbers and the risk of spreading infection. Cleaning is an important process already performed by coach operators during their regular activities (end of day or end of shift). Operators must continue and increase as much as possible the frequency of their cleaning routine during pandemic times. DISINFECTING refers to the use of chemicals to kill germs on surfaces. This process does not necessarily clean dirty surfaces or remove germs, but by killing germs on a surface after cleaning, it can further lower the risk of spreading infection. Disinfecting is an additional process (applied to specific high traffic - high contact areas of the coach) that should be performed by coach operators after the regular cleaning process to further reduce the risk of virus propagation during pandemic times. PROCEDURE DANGER Park vehicle safely, apply parking brake, stop engine. Prior to working on the vehicle, set the ignition switch to the OFF position and trip the main circuit breakers equipped with a trip button. On Commuter type vehicles, set the battery master switch (master cut-out) to the OFF position. 1. If possible, the vehicle central HVAC should be run at fresh air setting and at the highest setting possible. Change filters regularly. Do not run the parcel rack HVAC since this unit recirculates internal air not bringing outside fresh air. 2. If HVAC cannot be activated (vehicle not running), open side windows as much as possible to increase ventilation. 3. Proceed to the regular cleaning of the vehicle. 4. Follow cleaning with disinfecting process. Use the checklist provided at the end of this document to ensure that all areas of concern are disinfected. Checklist can be printed and dispatched to maintenance crew. MI20-09/ Page 4 / 6 VEHICLE QUARANTINE PROCEDURE (APTA RECOMMENDATION) IF A VEHICLE WAS SUBJECTED TO A KNOWN VIRUS EXPOSURE, PROCEED AS FOLLOWS: • Develop protocol for cleaning and disinfecting a vehicle after a person with COVID-19 was known to be in the space: • Designate special “quarantine” parking zones for any vehicles that have suspected or known exposure to the virus. • If the operator is still in the vehicle immediately after known exposure, ask the operator to perform the following steps, which allow for sufficient air changes to remove potentially infectious particles: o Park the vehicle in designated area. o Leave the engine running and turn on HVAC to maximum fan speed. o Open windows (if possible) and vehicle door. o Use lockdown procedures to ensure nobody can enter/exit vehicle while quarantined; this could include additional steps such as license plate removal and placing caution/warning signs on the vehicle. Based on guidance provided for cleaning/disinfecting the vehicles, as long as air changes are occurring in vehicle via continuous running of HVAC and/or opened windows while vehicle is in use, personnel can enter the vehicle for cleaning/disinfection after approximately 30 minutes. Refer to page 6 of the APTA American Public Transportation Association - The COVID-19 Pandemic Public Transportation Responds: Safeguarding Riders and Employees for additional information.
