Concrete Pumping Safety: 5 Essential Protocols for Nsw Sites

Ensuring safety during concrete pumping involves adhering to five essential protocols: engaging a licensed and trained operator, positioning the pump on stable ground with fully extended outriggers, maintaining safe distances from overhead power lines, conducting thorough pre-start checks on hoses, clamps, and the hopper grate, and establishing an exclusion zone along with a safety briefing before commencing the first load. SafeWork NSW outlines the potential hazards and control measures in its fact sheet on concrete placing equipment operations, which this guide aligns with.

Essential Guidelines for Concrete Pump Safety

• Operating a concrete placing boom in NSW requires a PB class high risk work licence.
• The roles of line pump operator and line hand should be assigned to two distinct individuals.
• A concrete boom operated by someone without electrical line hazard training must maintain a distance of at least 3 metres from power lines up to 132,000 volts.
• Flexible hoses on a line pump must be secured while priming the line or clearing a blockage.

What Hazards Should You Be Aware of When Operating a Concrete Pump?

SafeWork NSW has identified numerous incidents involving concrete placing equipment over recent years, including failures of pipelines and couplings that result in concrete leaks under pressure, failures of boom components, booms coming into contact with overhead power lines, and delivery hoses whipping during operation. Additional risks include boom pumps tipping over and workers reaching into moving parts due to modified, broken, or missing hopper grates. Notably, hose whip incidents have led to severe injuries and even fatalities.

The same fact sheet highlights the hazards faced by workers during the setup or operation of a concrete pump:

• Steep slopes or unstable ground that cannot support the weight of the pump
• Using the pump for unintended purposes or beyond its design specifications
• Contact with overhead power lines
• Collisions with personnel, structures, or other equipment, such as concrete agitator trucks
• Uncontrolled hose whip or line movement
• Sudden release of concrete or pump components following a failure or blockage
• Crush points, moving parts, and confined spaces
• Exposure to diesel fumes and excessive noise
• Slippery surfaces and potential trip hazards

1. Engage a Licensed and Competent Concrete Pump Operator

SafeWork NSW mandates that concrete pump operators and surrounding workers must be trained and competent in the specific type and model of pump they are operating, as well as possess the appropriate high risk work licence. For boom pumps, this licence is the concrete placing boom (PB) class, which encompasses both truck-mounted and satellite-mounted booms. Operators should also be aware of the operational limits established by the manufacturer for each pump.

In the case of a line pump, the operator and the line hand must be separate individuals. The fact sheet specifies that the operator should maintain control of the pump at all times to ensure it can be quickly stopped in the event of a blockage or leak. A line hand may not be necessary if the discharge hose remains stationary throughout the pour, such as at a lift base. for truck-mounted boom operations, one individual can manage both the boom and the pump.

If your principal contractor requests a verification of competency (VOC) record for the pump operator, please inform us at the time of booking so that we can prepare the necessary paperwork ahead of pour day.

2. Position the Concrete Pump on Stable Ground

One of the incidents listed by SafeWork NSW is the tipping of a boom pump. The fact sheet emphasises the importance of considering ground conditions, or the structural integrity beneath a suspended slab, when determining the pump's location. The pump must be placed to allow for full deployment of the outriggers.

The positioning should facilitate an exclusion zone around the pump, keep the boom clear of buildings, and maintain appropriate distances from power lines. For sites with limited access, our guide to concrete pumping in tight spaces details how to plan the pump's position effectively.

3. Maintain Safe Distances from Overhead Power Lines

The SafeWork NSW Work near overhead and underground electric lines Code of Practice (May 2026) categorises concrete placing booms under its section on cranes and mobile plant. According to the code, a worker who lacks training in electrical line hazards is deemed an ordinary person. For mobile machinery operated by such a person, Table 1 of the code specifies approach distances: 3.0 metres from overhead lines up to 132,000 volts, 6.0 metres for lines up to 330,000 volts, and 8.0 metres for lines exceeding 330,000 volts.

The code further stipulates that a safety observer should be present when a crane, mobile plant, or its load is in motion and may come within the prescribed distances. The observer's responsibility is to alert the operator and crew to maintain the appropriate distances and to identify any other unsafe conditions. Trained personnel working with an observer can operate within the reduced distances outlined in Table 2 of the code.

Before booking a boom pump, assess the area from both the truck's parking position and the reach of the boom. Be sure to mention any nearby power lines during your call, so we can strategically plan the pump's position.

4. Conduct Pre-Start Inspections on Hoses, Clamps, and Hopper Grate

SafeWork NSW insists that pre-operational checks are essential for all concrete placing equipment, with inspections, testing, and maintenance adhering to the manufacturer's guidelines. Specifically, the fact sheet requires two critical checks before the pump is operated: verifying the functionality of the interlock on the hopper grate and ensuring that safety pins are properly fitted to each delivery line clamp.

The interlock on the hopper grate is crucial because opening the grate or activating the emergency stop should halt all dangerous moving parts and release accumulator pressure. Such safety devices must never be altered, bypassed, or disabled. All inspections and maintenance activities should be documented, and Australian Standard AS 2550.15:2019 (Cranes, hoists and winches, Safe use, Concrete placing equipment) provides additional details on inspection protocols.

Strategies to Prevent Hose Whip on a Concrete Line Pump

Hose whip refers to the uncontrolled movement of a flexible delivery hose under pressure. SafeWork NSW advises that flexible hoses on line pumps must be secured while the line is being primed or when clearing a blockage. a coupling should never be attached to the end of a line pump while it is in operation.

5. Establish Exclusion Zones and Conduct a Safety Brief Before Pouring Concrete

SafeWork NSW requires that the pump be positioned to allow for a pedestrian exclusion zone to be established and maintained around it, with traffic management or spotters deployed as necessary. During our pours, the exclusion zone ensures that no one stands under the boom or directly in front of the discharge hose, with barriers or flagging clearly marking the area.

The fact sheet also recommends discussing the pour's impact with relevant parties before setting up the pump. This includes the principal contractor, other trades on site, your workers, local authorities, and individuals in neighbouring properties. Prior to the pump's operation, the crew's safety briefing should address:

• Site access and hose routing
• Emergency procedures and first aid plans
• Designated staging and wash-out locations for agitator trucks
• Slip hazards and personal protective equipment (PPE)
• Identification of the spotter, if one is required
• Coordination of the pour

One individual should be appointed to call the pour. This person will coordinate the actions of the agitator drivers, hose handlers, site supervisor, and concrete workers, ensuring that everyone receives instructions from a single source.

Is There a Specific Concrete Pumping Code of Practice in NSW?

The SafeWork NSW fact sheet on concrete placing equipment references 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 outlines responsibilities for all parties involved, from the individuals who design and supply the pump to the principal contractor, the pump operator, and the workers present on site.

Can the Line Pump Operator Also Handle the Hose?

According to SafeWork NSW, the line hand and the line pump operator must be two separate individuals. The operator must maintain control of the pump to ensure it can be quickly stopped if the line blocks or leaks. A line hand may not be necessary if the hose remains stationary throughout the pour.

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

Ensure that the ground where the pump will be parked is firm and level enough to support the outriggers. Look for overhead power lines in proximity to the pump and pour area, check for trip hazards along the hose route, and decide where the agitator trucks will wait and wash out. Our guide on common mistakes when hiring a concrete pump covers the booking process in detail.

Schedule a Concrete Pump with Comprehensive Safety Checks

Inform us of the pour location, how the pump can access it, and any overhead or underground obstacles that might pose a risk. We will collaborate with you to plan the pump's position, hose route, and exclusion zone in advance of pour day.
