Full Breakdown
Municipal Code Section 5-9-409(B)(ix), adopted by Ordinance No. 1 to the California Fire Code. It provides that 'during any time of the year within Wildfire Risk Areas, within or immediately adjacent to any forest- or brush-covered land or nonirrigated grass-covered land, no person shall use or operate any welding equipment, cutting torches, tar pots, grinding devices, or other tools or equipment that may produce a spark, fire, or flame that could result in a wildfire' without meeting four conditions. First, the operator must clear 'all flammable material, including snags, from the area around such operation for a distance of 30 feet,' or use another AHJ-approved method if the 30-foot clearing can't be achieved.
Second, the site must keep 'one serviceable round point shovel with an overall length of not less than forty-six (46) inches and one backpack pump watertype fire extinguisher fully equipped and ready for use' during the work. ' Fourth, operators must keep a cell phone on hand to call 911 immediately if a fire starts. A related provision, Section 327, separately requires spark arresters on internal combustion engines operated in or near any hazardous fire area.
Violations & Fines
OCFA enforces Section 327.1 violations under Section 5-9-305, assessing penalties per its Prevention Field Services fee schedule with each day of continuing non-compliance a separate offense. Operating spark-producing equipment in a Wildfire Risk Area without the required clearing, tools, or wind-based stop-work compliance can be charged as an infraction, escalating to a misdemeanor under Section 113.4.2 if a resulting hazard isn't abated when ordered.
