Concrete Pumping Safety Essentials for NSW Sites

To ensure safety during concrete pumping activities, it is vital to follow five essential protocols: hiring a licensed and skilled operator, placing the pump on solid ground with fully extended outriggers, maintaining safe distances from overhead power lines, performing thorough pre-start inspections of hoses, clamps, and the hopper grate, and creating an exclusion zone while conducting a safety briefing before the initial load. The guidance from SafeWork NSW highlights possible hazards and control measures related to the operation of concrete placing equipment, which this guide reflects.

Key Safety Protocols for Concrete Pump Operations

• In NSW, a PB class high-risk work licence is required to operate a concrete placing boom.
• The responsibilities of the line pump operator and line hand must be assigned to two separate individuals.
• A concrete boom operator lacking 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 or when clearing blockages.

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

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

The accompanying fact sheet identifies several hazards 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 purposes other than intended 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. Hire a Qualified and Experienced Concrete Pump Operator

SafeWork NSW mandates that concrete pump operators and nearby workers must be trained and competent in the specific type and model of pump they are using, as well as hold the appropriate 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 set by the manufacturer for each pump.

For 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 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 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 when booking so we can prepare the necessary documentation ahead of the pour.

2. Position the Concrete Pump on Firm 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 selecting the pump’s location. The pump must be positioned to allow for the complete deployment of the outriggers.

This 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 restricted access, our guide on concrete pumping in confined spaces offers strategies for effectively planning the pump’s location.

3. Keep 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 defines a worker who lacks training in electrical line hazards as an ordinary person. For mobile machinery operated by such an individual, Table 1 of the code outlines 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 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 Checks on Hoses, Clamps, and Hopper Grate

SafeWork NSW emphasises that pre-operational checks are crucial for all concrete placing equipment. Inspections, testing, and maintenance should follow the manufacturer’s guidelines. Specifically, the fact sheet outlines two critical checks that must be carried out 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 is vital, as opening the grate or activating the emergency stop should halt all hazardous moving parts and release accumulator pressure. These 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) provides further insights into inspection protocols.

Prevention Strategies for 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 in operation.

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

SafeWork NSW requires that the pump be placed 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 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 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 appointed 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 positioned 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.

Secure a Concrete Pump with Comprehensive Safety Inspections

Please inform us of the pour location, how the pump can access it, and any overhead or underground obstacles that may pose a risk. We will work with you to plan the pump’s position, hose route, and exclusion zone before the day of the pour.
