Where may a bus not carry packages of radioactive material requiring hazard labels?
Correct answer: A – In a compartment occupied by people
Packages of Class 7 radioactive material requiring labels may not be stored in a compartment occupied by people. Federal rules direct that qualifying packages be placed only in the trunk or baggage compartment and handled under the applicable radioactive-material requirements. The Maryland manual states the same passenger-space restriction.
