Industrial Fire Precaution Levels 

I. Fire Season - Fire precaution requirements are in effect. In addition to the other fire prevention measures, a Fire Watch/Security is required at this and all higher levels unless otherwise waived.

II. Limited Shutdown ‑ The following may operate only between the hours of 8 p.m. and 1 p.m. local time: 

· Power saws except at loading sites;

· Feller-bunchers with rotary head saws

· Cable Yarding;

· Blasting;

· Welding or cutting of metal.

III. Restricted Shutdown ‑ The following are prohibited except as indicated:

· Cable Yarding - except that gravity operated logging systems employing non motorized carriages or approved motorized carriages may operate between 8 p.m. and 1 p.m. when all blocks and moving lines are suspended 10 feet above the ground except the line between the carriage and the chokers and during rigging (see approved motorized carriages)

The following are permitted to operate between the hours of 8 p.m. and 1:00 p.m. local time, where mechanized equipment capable of constructing fireline is immediately available to quickly reach and effectively attack a fire start:

· Ground based operations;

· Power saws on ground based operations;

· Rotary head saw feller-bunchers with a continuous firewatch;

· Non-rotary head saw feller-bunchers;

· Tethered logging systems;

The following are permitted to operate between the hours of 8 p.m. and 1:00 p.m.:

· Power saws at loading sites;

· Loading or hauling of any product or material;

· Blasting

· Welding, cutting, or grinding of metal;

· Any other spark emitting operation not specifically mentioned;

IV. Complete Shutdown ‑ All operations are prohibited.

NOTE: Where hauling involves transit through more than one shutdown / regulated use area, the precaution level at the loading site shall govern the level of haul restriction, unless otherwise prohibited by other than the IFPL system. Under IFPL III, all trucks must be loaded and leaving the loading site no later than 1 p.m.

Approved Motorized Carriage: a cable yarding system employing a motorized carriage with two fire extinguishers, each with at least a 2A: 10 BC (5lb) rating, mounted securely on opposite sides of the carriage, an emergency motor cutoff, and an approved exhaust system.

Cable Yarding System: a yarding system employing cables, and winches in a fixed position.

Fire Season (Fire Precautionary Period): that season of the year when a fire hazard exists as declared by the responsible agency official.

Ground-Based Operations: mobile and stationary equipment operations other than cable yarding systems, including but not limited to tractor/skidder, feller-buncher, forwarder, processor, and shovel operations.

Loading Sites: a place where any product or material (including, but not limited to logs, firewood, slash, soil, rock, poles, etc.) is placed upon a truck or other vehicle.

Tethered Logging System: winch-assisted, cable-assisted, traction-assisted, etc., which enable ground-based timber harvesting machines to operate on steep slopes.

 Best Management Practices for Forest Operations Checklist

· Assure good communications are established with protection district.

· Keep all equipment clean of flammable material and debris.

· Utilize and keep in good working condition manufacture recommended non-sparking clamping jaws on braking systems on carriages.

· Clean out spark arrester ports.

· Assure hydraulic and fuel lines are in good condition.

· Assure battery hold-downs are in good repair and positive terminal is insulated.

· Assure electrical wiring and circuit breakers are in good working order according to manufacture specifications.

· Assure pumps and fire trucks are in good working condition.

· Eliminate line rub.

· When not in use, park equipment overnight in location clear of flammable material.

· Monitor relative humidity hourly and consider shut down when relative humidity drops below 30 percent.


Waivers, written in advance, may be used for any and all activities. Activities for which waivers may be issued include, but not  limited to:

· Mechanized loading and hauling.

· Road maintenance such as sprinkling, graveling, grading, and paving.

· Ground-based or tethered operations where cable yarding using gravity systems or suspended lines and blocks, or other yarding systems where extra prevention measures will significantly reduce the risk of fire.

· Power saws at loading sites or in felling and bucking where extra prevention measures will significantly reduce the risk of fire.

· Maintenance of equipment (other than metal cutting, welding, and grinding) or improvements such as structures, fences and powerlines.
