The first thing is you want to protect your workers.   My talking to them about being safe while on the job.   Gloves and masks are the basic protection against spreading the virus.   It protects the crews and the customers while     they are at work in the home.  When the job is over have one member of the crew wipe down the inside of the cab.  Also spray downs the pads after the move . A simple anti -bacterial like Lysol will work even while the pads are   stacked neatly in your Van.  Have the crews wash there hands when the job is over .
