As used in this chapter:

“Hazardous fire area” means any area which is designated as a hazardous fire area by the board or the director pursuant to Section 4252 or 4253.

Upon the written petition of the owners or authorized agents of more than 50 percent of the land, including public land, within the exterior boundaries of any area of not less than 10,000 acres in size, upon which a fire hazard exists due to the presence of flammable material or cover, the board may designate such area as a hazardous fire area, and shall declare the period of time during which the area shall be so designated.

When the director determines that a fire hazard exists in any other area due to the presence of flammable material or cover, the director may by regulation designate the area to be a hazardous fire area. The regulation shall declare the period of time during which the area shall be designated.

Notice of the designation of each hazardous fire area designated pursuant to Section 4252 shall be given by the posting of notices at intervals of not greater than one mile along the exterior boundaries of the area or along roads and trails passing through the area.

When it is necessary in the interest of public peace or safety, the director, with the consent of the owner of any lands designated as a hazardous fire area, may declare those lands closed to entry by any person. Any public highway traversing

the hazardous fire area, shall, however, be excluded from the order of closure, and the closure to entry does not prohibit or curtail the entry or use of the lands by the owner of the lands or the owner’s agent, nor the entry by a federal, state or county officer upon the closed area in the performance of their official duties. All state and county law enforcement officers shall enforce

the order of closure.

Any order which is issued pursuant to Section 4256 shall be published twice in at least one newspaper of general circulation in any county that is affected by the order. The publication shall be separated by a period of not less than one week and not more than two weeks. The order shall also be posted in such public places in each county as the director may direct, and along roads and trails which pass through the areas declared to be closed to camping or entry.

Whenever the director determines that a fire hazard exists in any area within a state responsibility area due to the presence of flammable material or cover, the director, by regulation, may designate that area as a hazardous fire area for the purpose of prohibiting the use or possession of fireworks therein. The hazardous fire area shall include only those areas that are critical and hazardous due to the threat of wildfire to life, property, and natural resources posed by the fireworks. The hazardous fire area shall not include areas that are the responsibility of a county which is contracting for fire protection to the director.

The regulation may designate areas where specified types of fireworks, not otherwise prohibited, are allowed for industrial, commercial, or agricultural use, for ceremonies, or for emergency signaling.

No regulation adopted pursuant to this article shall prohibit or curtail the complete possession and use of any area by the owner of the area or the owner’s agent, except that the use or possession of fireworks shall not be allowed in a hazardous fire area designated pursuant to Section 4258, other than as designated for their use or possession pursuant to that section.
