Concrete Pumping Safety: 5 Essential Protocols for NSW Sites

To ensure safe operations during concrete pumping, adhering to five essential protocols is crucial: engaging a licensed and experienced operator, placing the pump on stable terrain with fully extended outriggers, maintaining safe distances from overhead power lines, conducting comprehensive pre-start inspections of hoses, clamps, and the hopper grate, and establishing an exclusion zone while conducting a safety briefing prior to commencing the first load. The guidelines set forth by SafeWork NSW highlight potential hazards and control measures associated with concrete placing equipment operations, which this guide encapsulates.

Essential Safety Protocols for Concrete Pump Operations

• A PB class high-risk work licence is necessary to operate a concrete placing boom in NSW.
• The roles of the line pump operator and line hand must be assigned to two different individuals.
• An untrained concrete boom operator must stay at least 3 metres away from power lines up to 132,000 volts.
• Flexible hoses attached to a line pump must be securely fastened during priming or when resolving blockages.

What Hazards Should Be Considered When Operating a Concrete Pump?

SafeWork NSW has reported various incidents involving concrete placing equipment in recent years. These incidents include 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. Additional risks involve boom pumps tipping over and workers reaching into moving parts due to modified or missing hopper grates. Hose whip incidents have led to severe injuries and 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
• Proximity to overhead power lines
• Collisions with personnel, structures, or other equipment, such as concrete agitator trucks
• Uncontrolled hose whip or line movement
• Unexpected release of concrete or pump components due to failures or blockages
• 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 Experienced Concrete Pump Operator

SafeWork NSW requires that both concrete pump operators and surrounding personnel are trained and competent in the specific type and model of pump they are using, along with holding the appropriate high-risk work licence. For boom pumps, this licence is classified under the concrete placing boom (PB) category, encompassing both truck-mounted and satellite-mounted booms. Operators should also be well-acquainted with the operational limits stipulated by the manufacturer for each pump.

For line pumps, it is essential that the operator and the line hand are two separate individuals. The fact sheet indicates that the operator must maintain control of the pump at all times, ensuring it can be quickly halted 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. When managing truck-mounted booms, one person can oversee both the boom and the pump.

If your principal contractor requires a verification of competency (VOC) record for the pump operator, please notify us at the time of booking so we can prepare the necessary documentation prior to the pour day.

2. Position the Concrete Pump on Stable Ground

One incident reported by SafeWork NSW involved the tipping of a boom pump. The fact sheet emphasises the importance of evaluating ground conditions and the structural integrity beneath a suspended slab when determining the pump’s location. The pump must be positioned to enable the full deployment of the outriggers.

The setup should create an exclusion zone around the pump, keeping the boom clear of buildings and ensuring adequate distances from power lines. For sites with restricted 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) classifies concrete placing booms under its section regarding cranes and mobile plant. According to this code, a worker without training in electrical line hazards is deemed an ordinary person. For mobile machinery operated by such individuals, Table 1 of the code specifies approach distances: 3.0 metres from overhead lines up to 132,000 volts, 6.0 metres from lines up to 330,000 volts, and 8.0 metres for lines exceeding 330,000 volts.

The code mandates that a safety observer must be present when a crane, mobile plant, or its load is in motion and may approach the designated distances. The observer’s role is to alert the operator and crew to maintain appropriate distances and identify any 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 location and the boom’s reach. Mention any nearby power lines during your call, which will assist us in strategically planning the pump’s position.

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

SafeWork NSW underscores the necessity of pre-operational checks for all concrete placing equipment, with inspections, testing, and maintenance conducted in alignment with the manufacturer’s guidelines. Specifically, the fact sheet highlights two critical checks that must occur before operating the pump: verifying the functionality of the interlock on the hopper grate and ensuring that safety pins are correctly fitted to each delivery line clamp.

The interlock on the hopper grate plays a vital role, 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 guidance on inspection protocols.

Strategies to Prevent Hose Whip in Concrete Line Pumping

Hose whip describes the uncontrolled movement of a flexible delivery hose under pressure. SafeWork NSW advises 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 Before Pouring Concrete

SafeWork NSW requires that the pump be positioned to facilitate the establishment and maintenance of a pedestrian exclusion zone around it, with traffic management or spotters deployed as necessary. Throughout our pours, the exclusion zone ensures that no individuals stand beneath 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 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 necessary
• 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 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 additional 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 individuals who design and supply the pump to the principal contractor, the pump operator, and the workers present on site.
