Concrete Pumping Safety: 5 Essential Protocols for NSW Sites

Ensuring safety during concrete pumping involves adhering to five essential protocols: hiring a qualified and licensed operator, placing the pump on stable ground 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 performing a safety briefing before the first load begins. The guidelines set forth by SafeWork NSW detail potential hazards and control measures associated with concrete placing equipment operations, which this guide reflects.

Detailed Safety Protocols for Concrete Pump Operation

• In NSW, a PB class high-risk work licence is mandatory for operating a concrete placing boom.
• Responsibilities must be divided between the line pump operator and the line hand, assigning them to two separate individuals.
• An untrained concrete boom operator must maintain a minimum distance of 3 metres from power lines up to 132,000 volts.
• Flexible hoses on a line pump should be securely fastened during priming and when clearing blockages.

What Risks Should Be Acknowledged When Operating a Concrete Pump?

SafeWork NSW has recorded numerous incidents involving concrete placing equipment in recent years. These incidents include pipeline and coupling failures resulting 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 fatalities.

The accompanying fact sheet outlines several hazards that workers may encounter during the setup or operation of a concrete pump:

• Steep slopes or unstable ground that cannot support the pump’s weight
• Using the pump for unintended tasks 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 Proficient Concrete Pump Operator

SafeWork NSW requires that both concrete pump operators and surrounding workers must possess training and competency in the specific type and model of pump being used, alongside holding the appropriate high-risk work licence. For boom pumps, this licence is classified under the concrete placing boom (PB) category, which encompasses both truck-mounted and satellite-mounted booms. Operators should also be knowledgeable about the manufacturer’s operational limits for each pump.

For line pumps, it is crucial that the operator and the line hand are distinct individuals. The fact sheet indicates that the operator must maintain control of the pump at all times, ensuring it can be swiftly stopped if a blockage or leak occurs. If the discharge hose remains static throughout the pour, such as at a lift base, a line hand may not be necessary. When operating truck-mounted booms, one person may effectively manage both the boom and the pump.

If your primary contractor requests a verification of competency (VOC) record for the pump operator, please notify us during booking to prepare the necessary documentation prior to the pour day.

2. Set the Concrete Pump on Stable and Solid Ground

Among the incidents documented by SafeWork NSW is the tipping of a boom pump. The fact sheet underscores 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 facilitate the full deployment of the outriggers.

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

3. Ensure Safe Distances from Overhead Power Lines

The SafeWork NSW Work near overhead and underground electric lines Code of Practice (May 2026) includes concrete placing booms in its section on cranes and mobile plants. According to this code, a worker without 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 also states that a safety observer must 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 to 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 location and the boom’s reach. Bring up any nearby power lines during your call, enabling us to strategically plan the pump’s position.

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

SafeWork NSW highlights that pre-operational checks are vital for all concrete placing equipment, with inspections, testing, and maintenance performed according to the manufacturer’s guidelines. Specifically, the fact sheet outlines two critical checks that must be completed 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 serves an essential function; 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, with Australian Standard AS 2550.15:2019 (Cranes, hoists and winches, Safe use, Concrete placing equipment) providing further 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. Never attach a coupling to the end of a line pump while it is operational.

5. Create Exclusion Zones and Hold a Safety Briefing Before 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, 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 suggests discussing the pour’s implications with key 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 necessary
• Coordination of the pour

A single 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 one 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 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 Manage the Hose?

According to SafeWork NSW, the line hand and the line pump operator must be two distinct individuals. The operator must retain control of the pump to ensure it can be swiftly 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 Check on My Site Before the Concrete Pump Arrives?

Make sure 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.
