Using machinery

8 min read

Vehicles, tools and farm machinery can start fires which threaten lives and property. It is your responsibility to keep your equipment maintained and operate it safely.

Summary

  • Farm machinery and vehicles can start fires due to their extremely hot exhaust systems.
  • Be very careful when harvesting, grinding, welding, slashing, mowing or bee smoking on hot, dry days.
  • Don't drive vehicles, quad bikes or motorbikes through dry grass or crops.
  • Keep your machinery and vehicles well maintained.
  • Check for the build-up of straw and grass while operating, especially around hot bearings.
  • Know what you can and can't do during the Fire Danger Period and on Total Fire Ban days.

Farm equipment can start a fire in seconds

Vehicles, farm machinery, welding/grinding and bee keeping equipment can start fires on your property if heat or sparks set crops, grass and other vegetation alight.

Care needs to be taken when using machinery powered by a petrol, diesel or gas engine. Catalytic converters and diesel particulate filters on these machines operate at extremely high temperatures and can ignite dry grass.

The following vehicles, tools and machinery are extremely risky to use in hot, dry conditions:

  • Chainsaws, mowers and brush cutters
  • Motorbikes, quadbikes, cars, utes and trucks
  • Tractors, harvesters and other farming vehicles.

Many activities performed on farms are banned on Total Fire Ban days.

Operating harvesters safely

The most common cause of harvest fires is crop dust and debris catching fire in the header's engine area, particularly the exhaust manifold or turbocharger.

You can reduce this risk by regularly cleaning down your header when harvesting, and staying on top of maintenance and routine inspections.

Don't harvest on hot and windy days, stop when conditions become too dangerous, and have multiple water carts available in the paddock at all times. Make sure everyone involved and on the farm is aware of what to do if a fire starts. Learn more about preventing harvest fires.

Carting hay safely

Cover your hay load or have a spark shield behind the exhaust when carting hay.

Consider fitting the exhaust system under the body of the vehicle so exhaust emissions are kept away from the flammable hay. But remember there's also a fire risk from the hot exhaust coming in contact with long dry grass. Learn more about preventing hay fires.

Using slashers, mowers, brushcutters and chainsaws safely

Using machinery and other equipment on higher fire risk days could start a bush or grass fire.

When using equipment with a heat engine on brown, dry vegetation, this equipment must be:

  • free from faults and mechanical defects that could cause an outbreak of fire
  • fitted with an efficient spark arrestor .

The person using the equipment must carry either:

  • a fully charged, working knapsack spray pump, with a capacity of at least nine litres or
  • a working, fully charged fire extinguisher, with a capacity of at least nine litres.

There shouldn't be anything that can catch fire easily within three metres of a hot engine, and someone must be in attendance at all times.

Harvesting timber safely

In accordance with the Code of Forest Practices for Timber Production (produced by the Department of Energy, Environment and Climate Action), timber harvesting must be based on a Timber Harvesting Plan. This plan may include fire protection restrictions. Work bans should be considered when the Fire Behaviour Index exceeds 35.

Operating farm equipment during restricted periods

Slashing grass can help slow the spread of fire. It has been known to start bush and grass fires, so only slash grass when it's green or when the fire risk is lower.

Private fire fighting equipment

Farmers should have a range of private fire fighting equipment to put out fires which start on their property. Everyone on the farm also needs to be trained how to use it in case of an emergency.
