MBTA COVID-19 Response Services WCC COVID-19 Risk Assessment
TRC worked closely with the Massachusetts Bay Transit Authority ( MBTA ) to implement a cleaning / disinfection protocol based on Centers for Disease Control & Prevention ( CDC ) guidelines and worked in tandem with contractors to monitor and perform verification sampling upon completion . We provided subject-matter expertise and engaged with the cleaning companies to provide guidance to modify existing practices as required as well as expertise regarding the use of Personal Protective Equipment ( PPE ). Over a period of 80 days ,
■ 19,000 ATP samples were collected from rail / rolling stock
■ 1,000 ATP samples were collected from stations / facilities
■ 35 TRC personnel supported the COVID-19 response effort
■ Buses sampled – 3022
■ Train cars sampled – 662
■ Vans / mobile ride share vehicles sampled – 50
Ongoing support includes measuring SARS-CoV-2 levels in rolling stock during revenue service , identification of possible air purification systems for use in rolling stock , and evaluation of cleaning and disinfection alternatives .
TRC was hired by Washtenaw Community College ( WCC ) in Michigan to assess how to implement physical distancing protocols , personal hygiene and PPE , and cleaning and disinfection for laboratory and classroom activities . TRC conducted a site inspection and task evaluation using the virtual assistance of instructors from each department and going through the activities that instructors and students would perform during the class period . Department specific recommendations were developed and covered administrative controls , PPE , and cleaning responsibilities for students , instructors , and custodial staff .
TRC also developed the Cleaning and Disinfections Protocol for WCC custodial staff and used real-time sampling results to verify the effectiveness of cleaning procedures . We used qualitative adenosine triphosphate ( ATP ) testing , which provides real-time organic loading data , to determine the effectiveness of the cleaning protocol by collecting pre- and post-cleaning samples . If cleaning deficiencies were identified , we worked with the WCC staff to modify the current protocols to achieve adequate cleaning and disinfection
