Require employees seeking approval to telecommute to designate a room or area as their home workspace and allow you to perform a hazard assessment inspection to verify that the workspace is safe, healthy and appropriate for the proposed use.
First Choice: Have a supervisor or manager visit the site and do a physical walk-through inspection (Policy, Sec. 3).
Second Choice: Do the inspection virtually by having the employee tape the space and/or submit detailed photos and a floor plan.
In either case, you can use the Checklist below to perform the hazard assessment.
