My company is a contrct manufacturer of medical device instruments,. We manufacture the components at one facility that are transported off-site to another building for assembly (facilities are only about 0.3 miles apart). The components are packaged in plastic bags which are placed in bins and/or boxes. Most of the time an employee's truck or car is used. What I am concerned about is "chain of custdy" requirements and whether we should have a company vehicle with a lockable cover for transport. Is this a big deal to regulatory whether it is a company owned truck, or employee's vehicle used for transport. I say yes, it need to be a company owned vehicle, with a lockable cover, that is checked for possible contamination (odors, dirt, grease, etc.). Can someone give me the specific regulatory requirements for this?
