The Fire Problem, Stated Plainly

A sawmill produces combustible dust as a byproduct of its core process, distributes it throughout the facility by conveyor and air handling, and operates machinery that produces heat, friction, and sparks. Add hydraulic oil, electrical equipment, and in many mills a dry kiln and a boiler, and you have an environment where ignition sources and fuel are continuously in proximity.\n\nThe loss history of the industry reflects it. Mill fires are frequent and often severe, with total losses not unusual, because once a fire reaches the dust accumulations and the conveyor systems it travels quickly through the structure.\n\nUnderwriters know this better than anyone, which is why their questions are so specific. They want to know about dust collection design and maintenance, housekeeping frequency and documentation, hot work permitting, infrared inspection of electrical equipment, bearing temperature monitoring, conveyor fire detection and suppression, dry kiln and boiler protection, and the separation between the mill, the kilns, the planer, the shop, and the lumber yard.

• Combustible dust is produced continuously and distributed throughout the facility
• Ignition sources include bearings, electrical equipment, hot work, and kiln and boiler operations
• Fires spread rapidly through conveyors and dust accumulations
• Underwriting focuses on dust control, housekeeping documentation, hot work, and separation

What Improves the Terms You Can Get

Mills that present well have a recognizable set of controls, and most of them are operational rather than capital intensive.\n\nDocumented housekeeping is the single most important item. Not a statement that you clean up, but a schedule, assigned responsibility, a checklist, and records. Underwriters and loss control engineers ask for the records.\n\nA hot work permit system with a fire watch, used consistently including by contractors, is next. A large share of mill fires start with maintenance or repair work.\n\nInfrared thermography on electrical equipment and bearing temperature monitoring catch failures before they ignite. So does a documented preventive maintenance program on conveyors, bearings, and dust collection.\n\nProtection and separation matter structurally. Sprinkler coverage with adequate water supply, spark detection and extinguishing in dust collection systems, conveyor protection, separation or fire rated construction between the mill and the kilns and the finished goods, and yard layout that keeps lumber stacks away from the building and from each other.

• Documented housekeeping with a schedule, assignments, and retained records
• A hot work permit and fire watch system applied to employees and contractors alike
• Infrared electrical inspections, bearing monitoring, and documented preventive maintenance
• Sprinkler protection with adequate water supply, plus spark detection in dust collection
• Separation between mill, kilns, planer, shop, and finished goods
• Yard layout and spacing for log decks and lumber stacks

Equipment Breakdown and Long Lead Machinery

Property coverage pays for fire and other covered perils. It does not pay for the headrig gearbox failing, the edger motor burning out, or the kiln fan failing, because mechanical breakdown is excluded.\n\nEquipment breakdown coverage addresses that, and in a mill it should be written broadly. The scheduled equipment list should include the main line drives, motors, gearboxes, hydraulic systems, the dust collection fans, the kiln fans and controls, the boiler, air compressors, and electrical distribution equipment.\n\nLead time is the real issue. Mill machinery is not a catalog purchase. A main line component can take many months to source, fabricate, and install, and in some cases the original manufacturer no longer supports the equipment. That turns a mechanical failure into a long outage, and it means the business income side of equipment breakdown deserves as much attention as the direct damage side.

• Mechanical breakdown is excluded under property forms; equipment breakdown coverage addresses it
• Schedule main line drives, hydraulics, dust collection and kiln fans, boilers, and electrical equipment
• Lead times for mill machinery are long and parts support can be limited on older equipment
• Set business income indemnity periods from the real replacement time for critical components

Have Your Mill Program Reviewed

Wood products property terms are driven by documentation as much as by construction. We work with sawmills, planing mills, treaters, and forestry operations and will review your property values, equipment breakdown schedule, and loss control documentation before your renewal.
