Concrete Pumping Safety on Site: 5 Protocols Every Crew Should Follow on NSW Pours

Concrete pumping safety comes down to five protocols: a licensed and trained operator, a pump set up on firm ground with the outriggers out, safe distances from overhead power lines, pre-start checks on the hoses, clamps and hopper grate, and an exclusion zone with a safety brief before the first load goes in. SafeWork NSW sets out the hazards and the controls in its concrete placing equipment operations fact sheet, and this guide follows it.

Key Points on Concrete Pump Safety

• Operating a concrete placing boom in NSW needs a PB class high risk work licence.
• The line pump operator and the line hand should be two different people.
• A concrete boom run by an operator without electric line hazard training stays at least 3 metres from power lines up to 132,000 volts.
• Flexible hoses on a line pump should be secured while the line is primed or a blockage is cleared.

What Are the Main Hazards When Operating a Concrete Pump?

SafeWork NSW lists incidents involving concrete placing equipment in recent years: pipelines and couplings failing and leaking concrete under pressure, boom components failing, booms touching overhead power lines, delivery hoses whipping on line pumps and booms, boom pumps tipping over, and workers reaching moving parts through a modified, broken or missing hopper grate. The fact sheet notes that hose whip has caused serious injuries and one death.

The same fact sheet names the hazards workers face when they set up or operate a concrete pump:

• Steep slopes or ground that cannot carry the weight of the pump
• Using the pump for a purpose it was not designed for, or outside its design limits
• Contact with overhead power lines
• Collisions with people, structures or other plant, such as concrete agitator trucks
• Uncontrolled hose whip or line movement
• Sudden release of concrete or pump parts after a failure or blockage
• Crush points, moving parts and confined spaces
• Diesel fumes and noise
• Slippery surfaces and trip hazards

1. A Licensed and Trained Concrete Pump Operator

SafeWork NSW expects concrete pump operators and the workers around them to be trained and competent on the type and model of pump they are using, and to hold the right high risk work licence. For a boom pump, that licence is the concrete placing boom (PB) class, which covers truck-mounted and satellite-mounted booms. The operator also needs to know the operating limits the manufacturer sets for that pump.

On a line pump, the operator and the line hand should not be the same person. The fact sheet also says the operator should stay in control of the pump at all times, so it can be stopped quickly if the line blocks or leaks. A line hand may not be needed when the discharge hose stays in one place for the whole pour, such as a lift base. On a truck-mounted boom, one person can run both the boom and the pump.

If your principal contractor asks for a verification of competency (VOC) record for the pump operator, tell us when you book so the paperwork is ready before pour day.

2. Setting Up the Concrete Pump on Firm Ground

A boom pump tipping over is one of the incidents SafeWork NSW lists. The fact sheet says the pump should be sited with the ground conditions in mind, or the strength of the structure underneath if it is set up on a suspended slab, and placed so the outriggers can be fully deployed.

The same siting decision also has to leave room for an exclusion zone around the pump, keep the boom clear of buildings and keep the right distance from power lines. If your block has tight access, our guide to concrete pumping in tight spaces explains how the pump position is planned.

3. Keeping the Concrete Boom Clear of Overhead Power Lines

The SafeWork NSW Work near overhead and underground electric lines Code of Practice (May 2026) names concrete placing booms in its chapter on cranes and mobile plant. The code calls a worker who has not been trained in electric line hazards an ordinary person. For mobile plant operated by an ordinary person, Table 1 of the code sets an approach distance of 3.0 metres from overhead lines up to and including 132,000 volts, 6.0 metres above that up to 330,000 volts, and 8.0 metres above 330,000 volts.

The code also says a safety observer should be present when a crane, mobile plant or its load is moving and may come closer than the Table 1 distances. The observer’s role is to warn the operator and the crew to keep the approach distance and to point out any other unsafe conditions. Trained persons working with a safety observer can work to the reduced distances in Table 2 of the code.

Before you book a boom pump, look up from where the truck will park and from where the boom will reach. Mention any power lines near the pour when you call, so the pump position can be planned around them.

4. Pre-Start Checks on the Hoses, Clamps and Hopper Grate

SafeWork NSW says pre-operational checks should always be done on concrete placing equipment, and inspection, testing and maintenance must follow the manufacturer’s requirements. The fact sheet asks for two specific checks before the pump runs: that the interlock on the hopper grate works, and that safety pins are fitted to every delivery line clamp.

The hopper grate interlock matters because opening the grate or pressing the emergency stop should stop the dangerous moving parts and dump the accumulator pressure. Safety devices like this must never be modified, bypassed or switched off. Inspections and maintenance should be recorded, and Australian Standard AS 2550.15:2019 (Cranes, hoists and winches, Safe use, Concrete placing equipment) gives more detail on what to inspect.

How to Prevent Hose Whip on a Concrete Line Pump

Hose whip is the uncontrolled movement of a flexible delivery hose under pressure. SafeWork NSW says flexible hoses on line pumps should be secured in place while the line is primed or a blockage is cleared, and that a coupling must never be attached to the end of a line pump while the pump is operating.

5. Exclusion Zones and a Safety Brief Before the Concrete Pour

SafeWork NSW expects the pump to be placed so that a pedestrian exclusion zone can be set up and kept in place around it, with traffic management or spotters where they are needed. On our pours, the exclusion zone means nobody stands under the boom and nobody stands in front of the discharge hose, and barriers or flagging mark the area.

The fact sheet also asks you to talk to the people the pour affects before the pump is set up. That can include the principal contractor, other trades on site, your workers, local authorities and the people in neighbouring premises. Before the pump starts, the crew’s safety brief covers:

• Site access and hose routing
• Emergency plans and first aid
• Where the agitator trucks stage and wash out
• Slip risks and PPE
• Who acts as spotter, if a spotter is needed
• Who calls the pour

One person should call the pour. That person coordinates the agitator drivers, the hose handlers, the site supervisor and the concreters and finishers, so everyone takes instructions from the same voice.

Is There a Concrete Pumping Code of Practice in NSW?

The SafeWork NSW fact sheet on concrete placing equipment points to three codes of practice and one Australian Standard for further guidance:

• Managing the risks of plant in the workplace code of practice
• How to manage work health and safety risks code of practice
• Work near overhead and underground electric lines code of practice
• AS 2550.15:2019 Cranes, hoists and winches, Safe use, Concrete placing equipment

The Work Health and Safety Act 2011 places duties on the people involved, from the people who design and supply the pump to the principal contractor, the pump operator and the workers on site.

How Hunter Concrete Pump Hire Runs Safety on Your Pour

Every pour we pump starts with a full equipment inspection of the hoses and reducers, the couplings and clamps, the boom and its seals, and the emergency shutoff systems, and the pump does not start until it passes every check. Our operators are trained, licensed and insured, and they follow the SafeWork NSW guidance on concrete placing equipment for line pump hire, boom pump hire and small pump hire across Newcastle, Maitland, Port Stephens and the Hunter.

Do I Need to Supply Spotters or Safety Personnel for My Concrete Pour?

For civil and commercial sites, yes. For residential pours, our pump crews manage the safety zone around the pump and hose. We’ll let you know what your site needs when we quote.

Can the Line Pump Operator Also Handle the Hose?

SafeWork NSW says the line hand and the line pump operator should not be the same person. The operator should stay in control of the pump so it can be stopped quickly if the line blocks or leaks. A line hand may not be needed if the hose does not have to be moved during the pour.

What Should I Check on My Site Before the Concrete Pump Arrives?

Check that the ground where the pump will park is firm and level enough for the outriggers, look for overhead power lines near the pump and the pour, clear trip hazards along the hose route, and decide where the agitator trucks will wait and wash out. Our guide to the common mistakes when hiring a concrete pump covers the booking side.

Book a Concrete Pump With the Safety Checks Planned

Tell us where the pour is, how the pump can reach it and anything overhead or underfoot that could get in the way, and we’ll plan the pump position, the hose route and the exclusion zone with you before pour day.
