Final answer:
A licensee may only use their facilities for non-operational activities such as administrative tasks or maintenance while their license is suspended, as regulated by specific laws.
Step-by-step explanation:
The only purpose for which a licensee can utilize their facilities while their license is suspended is to conduct non-operational activities that do not involve the licensed service or activity itself. These may include administrative tasks such as record-keeping, maintenance, or other necessary functions to preserve the facility and its ability to comply with licensing requirements upon reinstatement. However, this is generally governed by specific regulations and laws that vary depending on the jurisdiction and the type of license that is suspended.
