20 V.S.A. § 104

(a) Any party state requested to render aid or conduct exercises under this Compact shall comply fully with the terms of this Compact; provided that the state rendering aid may withhold resources necessary to reasonably protect itself. Each party state shall confer on the emergency forces of a party state, rendering aid within the limits of the requesting party state, the same duties, rights, privileges and powers, except the power to arrest, unless specifically authorized by the receiving state, afforded the forces of the state in which emergency services are being provided. Emergency forces will be commanded and controlled by their regular leaders, but the organizational units will be subject to the operational control of the emergency services authorities of the state receiving aid. These conditions may be activated as needed, only during a declared disaster or emergency, or while exercises or training for mutual aid is in progress or the loaned resources remain in the receiving state, whichever is longer.

(b) A person from a party state rendering aid under this Compact who holds a license, certificate, or other permit issued by that party state indicating that the person is qualified in some professional, mechanical, or other skill, shall be deemed licensed, certified, or permitted in the state requesting aid to render aid related to the license certificate or permit for a declared emergency or disaster, subject to limitations and conditions prescribed by the governor of the requesting state.
