Forwarder fires

During May and June, we have experienced 3 forwarder fires on different sites.

The outcomes of these have ranged from relatively minor damage where the operator noticed smoke, activated the on-board extinguisher system and used a portable extinguisher, to a total loss of a machine and timber stack it was parked next to when the fire started overnight. The exact causes of each of these fires is still being established, but our experience over the years shows that they have typically come from three sources:
1. Electrical Fires.
2. Oil leaks on hot exhausts.
3. Forest debris build up on hot engines or exhausts.
Whatever the ignition source, a build up of forest debris further fuels the fire.

What we learn from these events is that inspection, maintenance and cleaning are all highly important factors. An operator may not be able to physically see damage or deterioration on oil feed pipes or electrical wiring but they should be able to see and recognise a build up of debris in engine bays, belly pans etc and clear them out. Regular maintenance and servicing should be looking for deteriorating oil feed and electrical systems and taking action.
The ability to respond to a fire, should one take hold, has been demonstrated with these events. Make sure your on-board extinguisher system is charged and maintained, and portable fire extinguishers are available and to hand.

No-one should put themselves at risk to fight a fire, only use the extinguishers if trained and safe to do so.
