Each such company shall employ sufficient personnel to promptly put out fires on such road or right-of-way at times when such land is in a dry and dangerous fire condition. Each such company shall provide internal combustion engines of motive power other than steam used in road service, if not equipped with exhaust driven centrifugal turbocharger, shall have installed integral with the exhaust gas system, a spark- arresting device of a type certified according to the recommended practices of the association of American railroads and approved by the director so as to give the best practical protection against the escape of fire and sparks from the exhausts thereof.
No such company, or any employee thereof, shall deposit, cast, or discharge fire coals, or ashes or any other material capable of igniting fires on that part of its road or right-of-way which passes through forest land, or lands subject to fire from any cause, unless the fire therein is immediately extinguished. No such company, or employee thereof, shall place a lighted fusee along such roads or rights-of-way in such a manner as will cause the same to ignite inflammable substances which may cause fire to spread to forest land. In case of any uncontrolled or unguarded fire on such part of its road or right-of-way, the company shall use all practicable means to extinguish it even when the fire spreads to the property of another. Engineers, conductors, trainmen, or other persons who, while working for such companies, discover or know of any fire on, along or near such part of the road or right-of-way of their employer, shall report the same as soon as possible to the state forester or his duly authorized representative. Unless otherwise provided for by law, any such company, or any officer or employee thereof, violating any provision of this section, shall be guilty of a misdemeanor.
