Concrete Pumping Safety Protocols for NSW Sites

To maintain safety during concrete pumping operations, it is crucial to adhere to five primary protocols: engaging a licensed and skilled operator, positioning the pump on stable ground with fully extended outriggers, ensuring safe distances from overhead power lines, conducting comprehensive pre-start inspections of hoses, clamps, and the hopper grate, and establishing an exclusion zone along with performing a safety briefing before the first load commences. The guidelines put forth by SafeWork NSW highlight potential hazards and control measures associated with the operation of concrete placing equipment, which this guide reflects.

Essential Safety Protocols for Concrete Pumping Operations

• To operate a concrete placing boom in NSW, a PB class high-risk work licence is mandatory.
• 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 minimum distance of 3 metres from power lines up to 132,000 volts.
• Flexible hoses on a line pump must be securely fastened during priming and when clearing blockages.

What Risks Should Be Acknowledged When Operating a Concrete Pump?

Recent documentation from SafeWork NSW outlines various incidents involving concrete placing equipment. These incidents include failures of pipelines and couplings that result in concrete leaks under pressure, breakdowns of boom components, booms colliding 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. Hose whip incidents, in particular, have led to severe injuries and even fatalities.

The accompanying fact sheet identifies multiple hazards 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 outside its intended design or exceeding its specifications
• Contact with overhead power lines
• Collisions involving 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 personnel in proximity must be trained and competent in the specific type and model of pump in use, along with holding the correct high-risk work licence. For boom pumps, this licence falls under the concrete placing boom (PB) class, which includes both truck-mounted and satellite-mounted booms. Operators should also be aware of the operational limits specified by the manufacturer for each pump.

In the case of a line pump, it is essential that the operator and the line hand are distinct individuals. The fact sheet specifies that the operator must maintain control of the pump at all times, ensuring rapid stoppage in the event of a blockage or leak. A line hand may not be necessary if the discharge hose remains static throughout the pour, such as at a lift base. When using truck-mounted booms, one person can operate both the boom and the pump.

If your principal contractor requests a verification of competency (VOC) record for the pump operator, please notify us during the booking process so we can prepare the necessary documentation before the pour day.

2. Position the Concrete Pump on Stable Ground

Among the incidents recorded by SafeWork NSW is the tipping of a boom pump. The fact sheet stresses 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 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 ensure adequate distances from power lines. For sites with limited accessibility, our guide on concrete pumping in confined spaces provides strategies for effectively planning the pump’s placement.

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 this code, a worker without training in electrical line hazards is classified as 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 mandates that a safety observer must be present when a crane, mobile plant, or its load is in motion and may approach the specified distances. The observer’s role is to alert the operator and crew to maintain the correct 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 reserving 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, allowing us to strategically plan the pump’s placement.

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

SafeWork NSW emphasises that pre-operational checks are essential for all concrete placing equipment, with inspections, testing, and maintenance performed according to the manufacturer’s guidelines. Specifically, the fact sheet outlines two crucial checks that must be conducted prior to 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 has a vital function, as opening the grate or activating the emergency stop should halt all hazardous moving parts and relieve accumulator pressure. These 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) provides additional insights into inspection protocols.

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 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. Set Up Exclusion Zones and Conduct a Safety Briefing Prior to Concrete Pouring

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. During our pours, the exclusion zone ensures that no one stands 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 from 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 necessary
• Coordination of the pour

One individual should be designated 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 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 involved parties, from those who design and supply the pump to the principal contractor, the pump operator, and the workers 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 in the event of a blockage or leak. 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 stationed is firm and level enough to support the outriggers. Look for overhead power lines in the vicinity of 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.
