These tasksmust be assessed and, if the potentialfor serious injury is determined, controlmeasures should be put in place to reducethe likelihood that harm will occur.2) Cement hazardsOverseas research shows that 5%-10%of construction workers may be sensitised,or allergic, to cement. Exposing the skinto cement can cause both irritant andallergic dermatitis.Irritant dermatitis occurs because theabrasive and drying nature of cementHazardAccess pointsDuring set-up, pump workers manuallyhandle items such as timber pads, reducers,pipes and hoses. When handling theseitems, the terrain or the access to the workarea may increase the risk of injury.Using toolsThe use of hammers on clamps and theflapper box lever, if carried out in areas ofrestricted access, are tasks that may createan increased risk of injury due to workingin cramped positions.Hose handlingThe incorrect positioning of the pump,ineffective boom placement, wind forces oroscillation due to pumping may cause thehose-hand to forcibly restrain the hose inthe required position, risking strain injuries.Pipe workThe laying out of pipes is a task that requirescarrying bulky objects. The risk of injurypresented by this task can be increasedby walking long distances and the need tomanoeuvre pipes around obstacles.ObstaclesBending one’s back to move beneath objects,and stepping over obstructions whilstcarrying pipes increases the risk of injury.Loading/unloadingThe location and design of the storagepoints on the truck for things like pipes,hoses, reducers and outrigger pads havea bearing on the operators’ postures andthe distance these items must be carried.Clearing blockagesClearing blockages in pipelines can bea highly hazardous task, as their removalmay release built-up air pressure. This mayalso be the case during clean-up or whenremoving and inverting the hose reducerto empty out concrete.on the skin causes it to become dry,itchy, red and scaly. Allergic dermatitisis caused by a person becoming allergicto a chemical component in the cement,ControlsWhere practicable, establish walkways aroundthe site and keep it clear of obstacles anddebris. Provide non-slip ramps where workersare required to walk up inclines.Ensure that impact tools are kept in goodcondition; wear appropriate protectiveequipment, such as eye protection. Wherepracticable, ensure there is plenty of spaceto move.Plan the work before the pour commences,to ensure that the hose-hand can work in theoptimal area.Where practicable, use mechanical equipmentto lift and move bulky objects. Position bulkstores of equipment as close as practicable tolabour sites to minimise carrying.Where practicable, establish walkways that arekept clear of debris. Use mechanical equipmentto lift pipes over objects or up to higher floors.Position the truck as close as practicable to theconcrete pour site. Do not use hoses longer thanspecified by the concrete pump manufacturer.The end of the hose should not be enclosedby metal. Ensure that other personnel are keptclear of the pour area. The end-hose shouldnot be longer than what the concrete pumpmanufacturer recommends.Operators should be trained in how to recognisepotential air blockages in the hose. Eg: when firststarting, re-starting after moving, when the hopperis empty, if the concrete is too stiff and when thepump is reversed sometimes it may not be possibleto predict when an air blockage has occurred.usually chromium salts. This usuallyoccurs upon skin exposure to wet cement.Repeated exposure to cement can leadto allergic contact dermatitis.22www.mbie.govt.nz
