Working with hay bales

The first step to manage the risk of harm to workers working with hay bales is to identify the hazards related to the work tasks and the environment.

Do this by inspecting your farm and your work processes. Ask yourself:

• Is the bale handling equipment properly designed for the job?
• Is the equipment well maintained?
• Are my workers properly trained in the tasks I’m asking them to do?

Talk to your workers and ask:

• Are you aware of any potential hazards?
• How can we improve our safety and our processes?
• Do you know how to report a hazard?

Regularly review your own records, and consider:

• What do your workers’ compensation claims, recorded incidents, sick leave and worker complaints tell you about past incidents and hazards?
• What can you do to prevent the same things happening again?

Next, assess the level of risk posed by each hazard. The risk level is determined by:

• how serious the potential harm is
• how likely it is to happen.

The law requires you to eliminate the risks if practical, or to minimise them as much as possible.

Work through the hierarchy of controls to choose the control that most effectively eliminates or minimises the risks. This may involve a single control measure or combination of two or more different controls.

Find the hierarchy of controls in How to manage work health and safety risks Code of Practice 2021 (PDF, 0.65 MB).

Some controls apply to all tasks when working with hay bales, including:

• ensuring workers are properly trained and able to perform the task safely
• using plant and equipment that is designed for the task, well maintained and in good working order
• working on flat and even surfaces, where possible.

Other tasks have specific controls, listed below.

Falling or collapsing hay bales:

• Stack bales according to Australian Fodder Industry Association guidelines.
• Use correct lashing techniques when tying down bales on vehicles.
• If using tarpaulins, ensure they do not disturb or dislodge bales.
• Before unloading, check that bales have not moved during transport.
• Develop a load and unload sequence that stops the load from becoming unstable.
• Fit tractors with a well-maintained falling object protective structure (FOPS).
• Use equipment designed for hay bale handling, such as telehandlers, hay bale clamps, grabs, and spikes.
• If using a front-end loader attachment, ensure it is self-levelling and has a backboard.

A tractor without FOPS puts workers at risk of injury from a falling hay bale.

A self-levelling attachment will help balance the hay bale to prevent it falling. A backboard will prevent the bale falling backwards onto the operator.

Stack configuration:

• Ensure bales are of equal size and density.
• Check lower bales are sound and can provide stability for upper layers.
• Ensure the load doesn’t exceed truck or trailer dimensions, nor the maximum allowed axle and gross weights.
• Never strap or unstrap bales while the trailer is still being loaded or unloaded.
• Never climb on top of the load to place straps or tarps, use a lifting cage instead.

Electrocution from contact with overhead powerlines:

You do not need to make direct contact with powerlines to receive an electric shock. Electricity can jump or arc across air gaps.

• Put exclusion zones (how far workers and their equipment must stay away from powerlines, poles and stay wires) in place as outlined in the Electrical Safety Act 2002.
• Ensure workers are aware of where overhead powerlines are, understand where the exclusion zones are, and know the height and reach of equipment they are using.
• Don’t load or unload near overhead powerlines.
• Don’t stand on trucks or trailers while loading or unloading near to overhead powerlines.
  • Lower loading equipment, such as telescopic booms, masts of forklifts and front-end loader attachments when passing near or under overhead powerlines.

For more information about electrical safety and exclusion zones refer to:

• Electricity in the rural industry - Using it safely
• Electrical Safety Code of Practice 2010 Working Near Exposed Live Parts (PDF, 0.47 MB)

Following are examples of the clearances that people, machinery, and plant must maintain from powerlines.

Falling from heights:

• Use mechanical equipment or aids to load or remove bales, and to assist with placing or removing lashings, tarps, or other securing devices to stop the need for workers to climb on the stack.
• Ensure there’s a safe way for workers to move up onto and down from work positions that are above ground level.
• Give workers a way to get up onto and down from truck or trailer beds that doesn’t need them to jump from heights.

Keeping bystanders safe:

• Set up an exclusion zone to keep bystanders (including truck drivers) from the loading zone.
• Ensure no-one is on the opposite side of the truck or trailer during loading or unloading.
• Nominate a spotter (who has communication to the mobile plant operator) to prevent people entering the loading zone area.
• Ensure driving routes are well defined.
• Never transport workers on loads or loading equipment.
• Use signs or barriers to keep members of the public or anyone not involved with the loading or unloading operation away.

You should regularly review your control measures. Don’t wait for something to go wrong. If necessary, change or adjust your approach. The aim is to maintain a work environment that is without risks to health and safety.

Work health and safety laws require you to review controls:

• when you become aware a control measure is not working effectively
• before a change that might introduce a new risk
• when you find a new hazard or risk
• when your workers tell you that a review is needed
• after a health and safety representative requests a review.
