1 It includes the following activities: Manual TasksA manual task refers to any activity requiring a person to use any part of their muscular or skeletal system in their interactions with their work environment.It includes the following activities:PullingLiftingCarryingPushingHoldingStrikingThrowing
2 It also describes activities involving: Manual TasksIt also describes activities involving:Repetitive actionsSustained posturesExposure to Vibration
3 Manual Task InjuriesManual tasks can lead to injury through the development of Musculoskeletal Disorders (MSD).An MSD is an injury affecting the bones or soft tissue structure (other than organs) of the body that is caused by manual handling at work.Examples include sprains of ligaments; strains of muscles or tendons; injuries to the spine, joints, bones or nerves and abdominal hernias.
4 If you start to experience any of these symptoms don’t ignore them! Back or neck painPain in wrists shoulder or armsStabbing pains in arms or legsPainful jointsPain, tingling or numbness in hands or feetWeakness or clumsinessHeavinessBurning sensationsStiffnessSwellingIf you start to experience any of these symptoms don’t ignore them!
5 Responsibilities for Manual Tasks The University has a legislative requirement to eliminate risks related to manual tasks.In meeting this obligation, the University requires that managers and supervisors and those employees who design, manufacture or supply plant, premises, equipment or systems of work identify, assess and eliminate (or control) the range of hazards associated with manual tasks at the University.
6 Three Steps to Reducing Manual Task Injuries The three steps are:Identifying manual task hazardsAssessing the risk of those manual task hazards identified causing injuryEliminating the risk, or if not practicable reduce the risk to the lowest practicable level
7 Hazard Identification Identify all the plant, materials, equipment, premises, systems of work, the work environment and individual tasks which have the potential to contribute to a musculoskeletal disorder
8 Hazard Identification Manual task hazards can be identified in different ways:Walk through the workplace and look for potential hazardsTalk over risk factors with co-workersReviewing previous accidents and near misses
9 Assessing the RisksThe next step is to assess which factors are contributing to the risk of injury. Risk factors to be considered:Workplace or workstation layoutOther work conditionsCharacteristics of the itemLocation of objects and distances movedWork organisation and systems of workBody postureForceRepetition of movementsSpeed of movementsVibrationDuration
10 Assessing the RisksWeight of the object - heavy objects that have to be lifted awkwardly, such as from ground level are more likely to cause injury than objects lifted from waist levelEquipment - more effort may be required to manipulate badly designed or poorly maintained equipmentThe degree of effort - simply restraining an object such as an animal, can cause sprains and other injuriesType of work - some tasks require fixed postures for long periods of timeLayout of the work space - a poorly designed workspace may force people to maintain awkward postures, such as bending or twisting repetitivelyHandling time - the more often an object has to be handled, the greater the chance of injuryFurther information on assessing manual task risks and forms can be found on the manual task website
11 Eliminating (or Controlling) the Risk Hierarchy of ControlsELIMINATIONSUBSTITUTIONENGINEERINGADMINPPE
12 Common Risk Control Measures Change the workspace - for example, use ergonomic furniture and make sure work benches are at optimum heights to limit bending or stretchingChange the nature of the work - offer frequent breaks or multi-taskSeek proper training - inexperienced workers are more likely to be injuredChange the task - does this task need to be carried out? If so, does it have to be done this way?Change the object - for example, repack a heavy load into smaller, more manageable parcelsUse mechanical aids - like wheelbarrows, trolleys, conveyor belts, cranes or forklifts
13 Evaluation & Record Keeping Check the effectiveness of control measures in place and ensure no new hazards have been introducedRecord KeepingRecords should be kept of hazard identification, risk assessment and control measures including training records
15 Suggestions to protect your back include: Protecting Your BackYour back is particularly vulnerable to manual task injuries.Suggestions to protect your back include:Warm up cold muscles thoroughly before engaging in any manual workLift and carry heavy loads correctly, by keeping the load close to the body and lifting with the thigh musclesNever attempt to carry or lift loads in excess of the recommended maximum limit for one personMaintain correct posture and the natural curves of the spineTake frequent breaksOrganise the work area to reduce the amount of bending, twisting and stretching requiredGet help to lift or carry a heavy load whenever possible, using another worker or appropriate mechanical aidsCool down after heavy work with gentle, sustained stretchesExercise regularly to strengthen muscles & ligamentsLose any excess body fat
16 Safe Lifting Technique Plan the liftKeep the load close to your bodyMaintain the natural curves of your spineFor more information on safe lifting please see the Manual Task website
17 Stretches for Manual Tasks StretchingFollowing are some tips on how you can prevent manualtask injuries. The link below will allow you to viewsome suitable stretches.Stretch prior to doing any manual handling tasks.Exercise and take short breaks frequentlyCool down after any heavy lifting/manual handling.Prevention is better than cure! You can do just a few of the exercises anytime during the day. Try some of them before you get stiff and sore.Include a variety of movements in your workday.Some stretches may cause you pain or discomfort. If this occurs, stop the stretch immediately.Stretches for Manual Tasks
