Concrete Pumping Safety: Essential Protocols for NSW Sites

Ensuring safety during concrete pumping operations requires strict adherence to five vital protocols: employing a licensed and skilled operator, positioning the pump on stable ground with fully extended outriggers, maintaining a safe distance from overhead power lines, performing thorough pre-start inspections of hoses, clamps, and the hopper grate, and establishing an exclusion zone along with a safety briefing before commencing the first load. The guidelines issued by SafeWork NSW highlight the potential hazards and control measures associated with the operation of concrete placing equipment, which this guide aims to summarise.

Key Safety Protocols for Concrete Pump Operations

• A PB class high-risk work licence is essential for operating a concrete placing boom in NSW.
• The responsibilities of the line pump operator and line hand must be assigned to two different individuals.
• Operators of concrete booms without training in electrical line hazards must keep 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 or when clearing blockages.

What Risks Must Be Managed While Operating a Concrete Pump?

SafeWork NSW has documented numerous incidents involving concrete placing equipment in recent years. Such incidents include pipeline failures and coupling malfunctions that lead to concrete leaks under pressure, breakdowns of boom components, collisions between booms and 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, damaged, or missing hopper grates. Hose whip incidents have been particularly dangerous, resulting in severe injuries and even fatalities.

The accompanying fact sheet outlines several hazards that workers may face 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 applications 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. Employ a Licensed and Competent Concrete Pump Operator

According to SafeWork NSW, both concrete pump operators and personnel in the vicinity must possess training and competence in the specific model of pump they are using, as well as holding the appropriate 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 have a thorough understanding 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 two distinct individuals. The fact sheet states 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 necessary if the discharge hose remains stationary throughout the pour, such as at a lift base. When operating 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 during the booking process so that we can prepare the necessary documentation ahead of 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 assessing ground conditions and the structural integrity beneath a suspended slab when deciding on the pump’s location. The pump must be carefully 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 safe distances from power lines. For sites with limited access, our guide on concrete pumping in confined spaces offers 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) includes concrete placing booms in 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 individuals, 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 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 duty is to alert the operator and crew to maintain the required 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, evaluate 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 positioning.

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

SafeWork NSW highlights that pre-operational checks are crucial for all concrete placing equipment, with inspections, testing, and maintenance carried out in accordance with the manufacturer’s guidelines. Specifically, the fact sheet outlines two essential checks that must be completed before operating the pump: confirming 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 serves a critical role, as opening the grate or activating the emergency stop should halt all hazardous moving parts and release accumulator pressure. Such safety mechanisms must not be modified, bypassed, or disabled. All inspections and maintenance tasks should be documented, and Australian Standard AS 2550.15:2019 (Cranes, hoists and winches, Safe use, Concrete placing equipment) provides further guidance on 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 while clearing a blockage. A coupling should never be attached to the end of a line pump while it is operational.

5. Establish Exclusion Zones and Conduct a Safety Briefing Before Pouring Concrete

SafeWork NSW mandates that the pump be positioned to enable 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 stand 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 relevant stakeholders 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 deemed necessary
• Coordination of the pour

One individual should be designated as the pour caller. 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 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 separate individuals. The operator must retain control of the pump to ensure it can be rapidly 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?

Verify 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 identify 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.
