Wood Processing Industry – Risk and Loss Prevention

Scope and risk drivers

While fire protection in finished timber construction is mainly concerned with the fire resistance of installed wood elements, the wood processing industry is exposed to fire and explosion hazards arising from production itself: sawmills, particleboard plants and furniture factories store large quantities of raw timber, wood chips and sawdust, whose fine fractions can form explosible dust-air mixtures in extraction systems and silos. Freshly produced chips and sawdust are also prone to spontaneous combustion through biological and chemical decomposition processes if cooling and ventilation are inadequate.

Protection measures

Key measures include explosion protection concepts for extraction and silo systems, including spark detection and extinguishing in conveying ducts, a consistent separation of drying and storage areas to limit fire spread, and a systematic temperature monitoring programme for chip and wood-chip storage. Static electricity on conveying equipment and frictional heat from saws and millers are further industry-typical ignition sources that must be controlled through maintenance and earthing.

Insurance relevance

Due to the high fire load and rapid fire development in wood-dust atmospheres, sawmills and wood processing facilities rank among the property risks with above-average loss potential per unit area. Property insurers reviewing the risk regularly require evidence of functioning spark detection and explosion protection systems as well as documented temperature monitoring of storage areas.
