Work involving concrete pumps can be particularly hazardous if the concrete pump and related equipment is not maintained and inspected for safe use. Specific hazards also relate to the location on site where the pump is established and also the placement of the boom during use.
Silverback and subcontracted personnel are to comply with the relevant provisions of the following procedural requirements and references. The typical hazards addressed by this procedure include:
Documentation and Pump Review
- Full details of the procedure or methods for setting up, pouring, dismantling and removal of the pump is to be maintained by concrete pumping subcontractors. This documentation is to include the following information as relevant:
- a logbook that sets out complete details of all inspections, tests, repairs and modifications carried out on the equipment,
- that the plant has been competently inspected and is in safe working condition to undertake the necessary concrete pumping activities on site, and
- that only certified operators are to undertake concrete pump operations on site.
- Concrete pumping logbooks are to contain details of inspections, including:
- records of pre-operational inspections:
- daily before commencement of work,
- records of routine maintenance inspections:
- three monthly,
- records of annual inspections by a concrete pump assessor, and
- record of assessment for service and continued use – six yearly by a certified third party competent person.
- No pump is to be used on site unless it is registered and a copy of the registration is held with the pump.
- Warning and safety signs and relevant pipe identification and markings are to be located on the pump.
- Only those workers who are competent and who posses the relevant certificates of competency are to undertake concrete pump operation. Documentation detailing those qualifications held by certain workers, are to be maintained at the concrete pump controls at all times.
Prior to Concrete Pouring
- The pump position is to be clear of obstructions, have level ground and be capable of supporting the pump unit and the access route of the concrete delivery trucks.
- Safe access for workers and members of the public is to be maintained in the vicinity of the pumping unit..
- All outriggers are to be fully extended and sole plates correctly placed to support the load.
- A means of communication between the pump and the work face is to be established prior to pumping.
- Signage and barricading where required, is to be erected to form exclusion zones prior to the pour.
- All minor formwork and edge on ground works undertaken by Silverback or subcontractors is to be inspected by a competent person prior to concrete pouring.
- Any major formwork apart form that listed above, must be inspected and have a certificate issued by a competent person prior to concrete pouring. Thus close consultation with the formwork contractor and concrete pump operator/subcontractor must be undertaken by an Silverback Construction Supervisor prior to pumping.
- Aspects such as weather, volume of concrete to be poured and the capacity of the equipment and concrete supplier are to be taken into account to ensure an efficient pour.
- Wind conditions and the position of the concrete boom is to be monitored at all times to ensure that the boom does not come into contact with surrounding overhead hazards and powerlines.
- Concrete placing booms must maintain a minimum distance of 3m from overhead powerlines during operation in accordance with SP:03 – Electricity and Portable Power Tool Use.
- Pump operators are to ensure that the communication measures are implemented effectively so that workers at the work face are ready for the concrete during pumping activities.
- Workers involved with the pour are to wear appropriate personal protective equipment relevant to the site and work activity and recommended by the Advisory Standard for Plant, Supplement 1 – Concrete Pumping. This may include: safety helmets, eye protection, hearing protection, reflective vests, gloves, safety boots, rubber boots, waterproof clothing, mesh type face protection for concrete spraying operations, etc.
