10 Heavy Machinery Safety Tips
Every Operator Should Know

Before starting any machine — whether it's an excavator, mini loader, roller or truck — walk around it and check for anything that could cause a problem mid-job. A breakdown on site is inconvenient. A breakdown mid-lift or mid-dig can be dangerous.

• Check for fluid leaks — hydraulic oil, engine oil, coolant
• Inspect tyres or tracks for wear, damage or correct tension
• Test all lights, horn and reversing alarm
• Check that all guards and safety covers are in place
• Test brakes and controls before moving off
• Look for loose bolts, cracked hoses or worn attachments

PPE won't prevent every accident but it dramatically reduces the severity of injuries when something goes wrong. The right gear depends on the machine and the site, but some items are universal across any heavy machinery operation.

• Hard hat — protects against falling objects and overhead strikes
• High-visibility vest — essential around moving machinery and vehicles
• Safety boots with steel toe cap — protects feet from crush injuries
• Gloves — for handling attachments, chains and rigging equipment
• Eye protection — when working near debris, grinding or demolition
• Hearing protection — for extended use of loud machinery

No amount of common sense replaces proper training on heavy machinery. Each machine type handles differently — an excavator, a skid steer and a roller all have different controls, blind spots and tipping risks. Untrained operators are the most common cause of serious machinery accidents.

In Queensland, operating certain classes of plant requires a High Risk Work licence under the Work Health and Safety Regulation. Check what applies to the specific machine you're operating. For smaller machines like mini loaders and plate compactors, no licence is required — but a thorough site briefing and machine familiarisation still matters before the first use.

Every machine has a rated capacity, a safe operating speed and specific restrictions on what attachments it can run. These limits aren't conservative suggestions — they're the point beyond which the machine behaves unpredictably. Overloading a bucket, running an attachment beyond its rated flow or exceeding a slope gradient can cause rollovers, hydraulic failures and structural damage.

• Never exceed the rated load capacity of the machine or attachment
• Only use attachments that are rated and approved for that machine
• Follow the maintenance schedule — particularly for hydraulic fluid and filters
• Check the operator manual for slope limits before working on inclines

Most machinery incidents that involve bystanders or ground workers happen because of a communication breakdown — the operator didn't know someone was in the work zone. Establish site communication procedures before work starts, not after an incident.

• Agree on standard hand signals before starting work
• Use a spotter when reversing or operating in congested areas
• Never move a machine until the spotter is clearly visible
• Keep radios or phones accessible for larger sites
• Establish clear exclusion zones around operating machinery

Before starting work, do a full site walkthrough. Identify overhead powerlines, underground services, soft ground, slopes and any pedestrian or vehicle traffic routes that cross the work area. Things change throughout the day — a safe path at 7am may have a parked car or a pile of materials blocking it by 10am.

• Check for overhead powerlines — minimum clearance distances apply
• Call Dial Before You Dig before any excavation work
• Identify soft ground edges, trenches and drop-offs around the site
• Know where pedestrians and other vehicles are at all times
• Re-check surroundings after breaks or when site conditions change

Heavy machinery carries significant momentum even at low speeds. A loaded excavator bucket or a tipper truck in motion takes far longer to stop than a car. Speed on a construction or landscaping site should always be the minimum needed to do the job — not the maximum the machine is capable of.

• Slow down when turning, especially on slopes or with a raised load
• Never travel with a raised attachment unless the machine is rated for it
• Reduce speed on soft ground, gravel or uneven terrain
• Avoid sudden direction changes — they stress the drivetrain and reduce control

Improper load handling is one of the most common causes of machine tip-overs. The tipping point of any machine changes with load weight, load position, ground slope and travel speed. What's stable on flat ground can tip on a slope with the same load.

• Never exceed the rated bucket or attachment capacity
• Keep loads low when travelling — raise only at the work point
• Centre the load — avoid carrying loads to one side
• Approach slopes straight on, not at an angle, with a loaded attachment
• Secure trailer loads with appropriate rated straps before moving

An unattended machine that rolls, tips or starts unexpectedly causes as much damage as one in active use. End-of-day and end-of-shift procedures matter, especially on sloped sites or sites with public access.

• Park on level ground wherever possible
• Lower all attachments to the ground before leaving the machine
• Engage the park brake and put the machine in neutral
• Turn off the engine and remove the key
• Do not park near edges, trenches or unstable ground
• If on a slope, chock the wheels or tracks as a secondary measure

Emergencies on site happen fast. The worst time to work out what to do is when something has already gone wrong. Every person on site — not just the operator — should know the basic emergency procedures before work starts.

• Know where the emergency stop is on every machine you operate
• Know the site's emergency contact numbers and nearest hospital
• Have a first aid kit accessible on site at all times
• Know what to do if a machine tips — do not jump, stay in the cab
• Know the fire extinguisher location and how to use it
• Have an incident reporting process in place before work starts
