Va. Code § 10.1-1139
Any forest warden to whom written instructions have been issued by the State Forester authorizing him to employ persons to assist in suppressing forest fires, shall have the authority to summon as many able-bodied persons between eighteen and fifty years of age as may, in his discretion, be reasonably necessary to assist in extinguishing any forest fire in any county or city of the Commonwealth which is organized for forest fire control under the direction of the State Forester. Any person summoned by a forest warden to fight a forest fire shall be paid at the rate of pay provided in the Department of Forestry wage scale for fire fighting in effect in the county or city, or part thereof, in which the fire is fought. Wardens shall not summon for such service any person while engaged in maintaining the rights-of-way of railroads for the safe passage of trains, nor any station agent, operator or other person while engaged in duties necessary for the safe operation of trains.
Any person summoned who fails or refuses to assist in fighting the fire, unless the failure is due to physical inability or other valid reason, shall be guilty of a Class 4 misdemeanor.
