Concrete Pumping Safety: 5 Essential Protocols for NSW Sites

To guarantee safety during concrete pumping operations, adhering to five essential protocols is crucial. These include hiring a licensed and experienced operator, placing the pump on stable ground with fully extended outriggers, maintaining safe distances from overhead power lines, conducting thorough pre-start inspections of hoses, clamps, and the hopper grate, and establishing an exclusion zone alongside a safety briefing before the first load begins. This guide reflects the guidelines set forth by SafeWork NSW, which detail potential hazards and control measures associated with concrete placing equipment operations.

Essential Safety Protocols for Concrete Pump Operations

• In NSW, operating a concrete placing boom requires a PB class high-risk work licence.
• The roles of the line pump operator and line hand must be assigned to two separate individuals.
• A concrete boom operator without training in electrical line hazards 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 securely fastened during priming or when clearing blockages.

What Are the Key Hazards When Operating a Concrete Pump?

Recent documentation from SafeWork NSW has highlighted various incidents involving concrete placing equipment. These incidents have included failures of pipelines and couplings that resulted in concrete leaks under pressure, breakdowns of boom components, booms colliding with overhead power lines, and delivery hoses whipping during operation. Other significant risks include boom pumps tipping over and workers reaching into moving parts due to modified, broken, or missing hopper grates. Hose whip incidents, in particular, have caused severe injuries and even fatalities.

The accompanying fact sheet identifies several hazards that workers may encounter 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 purposes other than intended or exceeding 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 due to 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 Skilled Concrete Pump Operator

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

In the case of a line pump, it is essential for the operator and the line hand to be two distinct individuals. The fact sheet specifies that the operator must maintain control of the pump at all times, ensuring it can be promptly stopped in the event of a blockage or leak. A line hand may not be needed if the discharge hose remains stationary throughout the pour, such as at a lift base. When operating truck-mounted booms, 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 we can prepare the necessary documentation in advance of pour day.

2. Place the Concrete Pump on Stable Ground

Among the incidents documented by SafeWork NSW is the tipping of a boom pump. The fact sheet highlights the importance of assessing ground conditions and the structural integrity beneath a suspended slab when determining the pump’s location. The pump must be situated to allow for the full deployment of the outriggers.

The positioning should create an exclusion zone around the pump, keep the boom clear of buildings, and maintain appropriate distances from power lines. For sites with limited access, refer to our guide on concrete pumping in confined spaces for effective planning strategies regarding the pump’s position.

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 within its section on cranes and mobile plant. According to this code, a worker who lacks training in electrical line hazards is considered 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 requires a safety observer to be present when a crane, mobile plant, or its load is in motion and may come within the specified approach distances. The observer’s responsibility is to alert the operator and crew to maintain the appropriate distances and identify any unsafe conditions. Trained personnel working alongside an observer can operate within the reduced distances indicated in Table 2 of the code.

Before booking a boom pump, assess the area from both the truck’s parking location and the boom’s reach. 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 stresses that pre-operational checks are vital for all concrete placing equipment, with inspections, testing, and maintenance carried out according to the manufacturer’s guidelines. Specifically, the fact sheet outlines two crucial checks that must be performed before operating the pump: confirming the functionality of the interlock on the hopper grate and ensuring safety pins are properly fitted to each delivery line clamp.

The interlock on the hopper grate serves a critical purpose, as opening the grate or activating the emergency stop should halt all hazardous moving parts and release accumulator pressure. Such safety mechanisms must never be modified, 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) offers further insights into inspection protocols.

How to Prevent Hose Whip in Concrete Line Pumping

Hose whip refers to the uncontrolled movement of a flexible delivery hose under pressure. SafeWork NSW recommends that flexible hoses on line pumps must be secured during line priming or when clearing a blockage. A coupling should never be attached to the end of a line pump while it is operational.

5. Create Exclusion Zones and Conduct a Safety Briefing Prior to Pouring Concrete

SafeWork NSW mandates 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, this exclusion zone ensures that no individuals are positioned beneath the boom or directly in front of the discharge hose, with barriers or flagging clearly marking the area.

The fact sheet also advises discussing the pour’s implications 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 encompass:

• 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 needed
• Coordination of the pour

A single 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 one source.

Is There a Specific Code of Practice Governing Concrete Pumping 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 the responsibilities of all parties involved, from those 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 Manage 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 becomes blocked or leaks. A line hand may not be necessary if the hose remains stationary throughout the pour.

What Should I Inspect 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 provides detailed insights into the booking process.

Schedule a Concrete Pump with Thorough Safety Inspections

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