Manual Handling Assessment Charts (the MAC Tool)

Health and SafetyExecutiveManual handling assessmentcharts (the MAC tool)IntroductionWork-related musculoskeletal disorders (MSDs), including manual handlinginjuries, are the most common type of occupational ill health in the UK. It isimportant to remember that: This is a web-friendlyversion of leafletINDG383(rev2),published 06/14there is a lot you can do to prevent them;preventative measures are often simple and cost-effective;you cannot prevent all MSDs, but where they occur, early reporting ofsymptoms, proper treatment and suitable rehabilitation are essential.The Manual Handling Assessment Charts (MAC) is a tool aimed at employers,health and safety managers and safety representatives and is used byhealth and safety inspectors. The tool will help individuals to assess the mostcommon risk factors in lifting (and lowering), carrying and team handlingoperations and was developed to identify high-risk manual handling.What does the law say?The Manual Handling Operations Regulations 1992 set out a clear hierarchy ofmeasures for dealing with risk likely to cause harm from manual handling. These are: avoid hazardous manual handling operations so far as reasonably practicable;assess any manual handling operations that cannot be avoided;reduce the risk of injury to as low as reasonably practicable.Structure of the MACThere are three types of assessment that can be carried out with the MAC: lifting operations (pages 3–6);carrying operations (pages 7–10);team handling operations (pages 11–13).For each type of assessment there is an assessment guide and a flow chart. There isa score sheet (the ‘MAC: Score sheet’) to complete on page 14.NoteThe MAC is not appropriate for some manual handling operations, for examplethose that involve pushing and pulling. Its use does not comprise a full riskassessment (see Manual handling in ‘Further reading’). Always consider individualand psychosocial issues when completing the ‘MAC: Score sheet’. Also, the MACis not designed to assess risks associated with workplace upper limb disorders(see Upper limb disorders in the workplace and Assessment of Repetitive Tasks ofthe upper limbs (the ART tool) in ‘Further reading’).Page 1 of 15

Health and SafetyExecutiveHow to complete a MAC assessmentG GREEN - Low level of riskAlthough the risk is low, consider the exposure levels for vulnerable groups such aspregnant women or young workers, where appropriate.A AMBER - Medium level of riskExamine tasks closely.R RED - High level of riskPrompt action needed. This may expose a significant proportion of the workingpopulation to risk of injury.P PURPLE - Very high level of riskSuch operations may represent a serious risk of injury and should come under closescrutiny, particularly when the entire weight of the load is supported by one person. Spend some time observing the task (videoing may help) to ensure that whatyou are seeing is representative of normal working procedures. You shouldinvolve your employees and safety representatives during the assessmentprocess. Where several people do the same task, make sure you have someinsight into the demands of the job from all employees’ perspective.Select the appropriate type of assessment (ie lifting, carrying or team handling).If a task involves lifting and carrying, consider both.Follow the appropriate assessment guide and flow chart to determine the levelof risk for each risk factor. Information on risk reduction can be found on theHSE website at www.hse.gov.uk/msd and in the HSE publication Manualhandling at work (see ‘Further reading’).Enter the colour band and corresponding numerical score on the ‘MAC: Scoresheet’. The colour bands help determine which elements of the task requireattention.Enter the remaining task information and use the scores to help identify whichrisk factors need to be examined and the total level of exposure to risk.If the individual does a number of tasks, assess each one separately andprioritise action to address the highest scoring task.Further guidance on using the MAC tool can be accessed online atwww.hse.gov.uk/msd/mac.RememberThe purpose of the assessment is to identify and then reduce the overalllevel of risk of the task.Manual handling assessment charts (the MAC tool)Page 2 of 15

Health and SafetyExecutiveAssessment guide for liftingoperationsA Load weight/frequencyNote the weight of the load and the repetition rate of the lifting operation. Take noteof the risk banding from the graph below and enter the colour band and numericalscore onto the ‘MAC: Score sheet’. If the colour band is purple, the task should beexamined very closely, as such operations may represent a serious risk of injuryand should come under close scrutiny, particularly when the entire weight of theload is supported by one person. Note: High frequency handling operations oflight weights will fall within the green zone, but may be associated with upper limbproblems. Please refer to Upper limb disorders in the workplace and Assessment ofRepetitive Tasks of the upper limbs (the ART tool) (see ‘Further reading’) for adviceon further assessment.Load weight/frequency graph for lifting operationsP 10Weight of load (kg)50405040R 63030A 420102010G 000One lift perday30 minutes(2)5 minutes(12)2 minutes(30)1 minute(60)14 seconds(250)9 seconds(400)5 seconds(720)One lift every(lifts per hour)Manual handling assessment charts (the MAC tool)Page 3 of 15

If the torso twists in relation to thehips and thighs or the operative leans to one side as the load is lifted, the colourband is amber and the numerical score is 1.

Look to see if the team have control ofthe load, that it is lifted smoothly, and that all members lift together. Anunco-ordinated team lift may leave one member of the team bearing the entire weight.GoodG/0ReasonableA/1Manual handling assessment charts (the MAC tool)PoorR/3Page 12 of 15
