Concrete Pumping Safety: 5 Essential Protocols for NSW

To ensure safety during concrete pumping operations, it is vital to follow five key protocols: hiring a licensed and skilled 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 creating an exclusion zone while performing a safety briefing before starting the first load. The guidelines from SafeWork NSW outline potential risks and control measures related to concrete placing equipment, which this guide reflects.

Critical Safety Measures for Concrete Pumping Operations

• In NSW, a PB class high-risk work licence is required to operate a concrete placing boom.
• Responsibility for operating the line pump and handling the line must be assigned to two separate individuals.
• An operator of a concrete boom who has not received training in electrical line hazards must maintain a minimum distance of 3 metres from power lines up to 132,000 volts.
• Flexible hoses on a line pump must be securely attached during priming or when clearing blockages.

What Safety Risks Must Be Recognised When Operating a Concrete Pump?

SafeWork NSW has recorded multiple incidents involving concrete placing equipment in recent years. These include failures of pipelines and couplings that lead to concrete leaks under pressure, breakdowns of boom components, collisions with overhead power lines, and delivery hoses whipping during operation. Additional hazards involve boom pumps tipping over and workers reaching into moving parts due to modified, broken, or missing hopper grates. Incidents of hose whip have resulted in serious injuries and even fatalities.

The accompanying fact sheet highlights several hazards workers may face 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 exceeding its design specifications
• Proximity to overhead power lines
• Collisions with personnel, structures, or 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. Hire a Licensed and Competent Concrete Pump Operator

SafeWork NSW mandates that both concrete pump operators and surrounding workers must be trained and competent in the specific type and model of pump they are using, as well as possessing the relevant high-risk work licence. For boom pumps, this licence falls under the concrete placing boom (PB) category, which includes both truck-mounted and satellite-mounted booms. Operators should be familiar with the operational limits specified by the manufacturer for each pump.

When using line pumps, it is essential that the operator and the line hand are two distinct individuals. The fact sheet specifies that the operator must maintain control of the pump at all times, ensuring it can be stopped promptly in case 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. When operating truck-mounted booms, one individual can manage both the boom and the pump.

If your principal contractor requires 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 prior to the pour.

2. Ensure the Concrete Pump is Positioned on Stable Ground

Among the incidents reported 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 positioned to allow for complete deployment of the outriggers.

The positioning should create an exclusion zone around the pump, keep the boom clear of buildings, and ensure adequate distances from power lines. For sites with limited access, our guide on concrete pumping in confined spaces provides strategies for effectively planning the pump’s location.

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. This code classifies a worker without training in electrical line hazards as an ordinary person. For mobile machinery operated by such a person, Table 1 of the code defines 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 that a safety observer be present when a crane, mobile plant, or its load is in motion and may come within the designated distances. The observer’s role is to alert the operator and crew to maintain the appropriate distances and identify any other unsafe conditions. Trained personnel working alongside an observer can operate within the reduced distances specified in Table 2 of the code.

Before booking a boom pump, assess the area from both the truck’s parking position and the boom’s reach. Please mention any nearby power lines during your call, so we can strategically plan the pump’s placement.

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

SafeWork NSW emphasises that pre-operational checks are essential for all concrete placing equipment. Inspections, testing, and maintenance should be conducted following the manufacturer’s guidelines. Specifically, the fact sheet outlines two critical checks that must be completed before operating the pump: 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, as opening the grate or activating the emergency stop should halt all hazardous moving parts and relieve accumulator pressure. Such safety mechanisms 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) offers further insights into inspection protocols.

Effective Strategies 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 securely fastened during line priming 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 Briefing Before Pouring Concrete

SafeWork NSW necessitates that the pump is positioned to allow the establishment and maintenance of a pedestrian exclusion zone around it, with traffic management or spotters deployed as needed. During our pours, the exclusion zone ensures that no individuals are positioned beneath the boom or directly in front of the discharge hose, with barriers or flagging clearly delineating the area.

The fact sheet also recommends discussing the pour’s implications with all 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 cover:

• 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 person should be designated to call the pour. This individual 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 Code of Practice for 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 for 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 distinct 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 near the pump and pour area, check for trip hazards along the hose route, and determine where the agitator trucks will wait and wash out. Our guide on common mistakes when hiring a concrete pump provides detailed information about the booking process.
