Mobile Laboratory Units and Temporary Testing Sites

6010.1 - Mobile Laboratory Units and Temporary Testing Sites (Rev. 230; Issued: 07-11-25; Effective: 07-11-25; Implementation: 07-11-25) • A mobile unit is generally considered to be a movable, self-contained operational laboratory with its own personnel, equipment, and records, with equipment installed and located permanently within the mobile unit. • If a vehicle is used solely to transport laboratory equipment from the primary site/home base to another site where testing is performed, the transporting vehicle is not a mobile unit. If a mobile laboratory operates in more than one State, CMS determines which state should perform an inspection. Each mobile laboratory that moves from testing site to testing site or has a temporary testing location, should provide the SA with the primary site/home base or central dispatch phone number, so that the SA can obtain an updated schedule of the location(s) of testing and the hours of operation. Records may be maintained in the mobile vehicle or at the primary site/home base. Reports should reflect the primary site/home base address and indicate which mobile unit performed each test. The vehicle identification number may be used to distinguish mobile laboratory vehicles.
