2. MANUAL HANDLING ASSESSMENT CHART (MAC TOOL)
Evaluating the load weight compared to the reaching distance
Red area : Lifting within the red area is without doubt harmful to health and must be avoided. To reduce the risk of injury control measures must be taken. Yellow area : Lifting within the yellow area requires a detailed evaluation of the aggravating factors. They must be considered to evaluate to what extent they enhance the strain on the muscular- skeletal system resulting in manual handling which is harmful to health. When lifting within the top most ⅓ part of the yellow area, manual handling is only accepted if it is performed under optimal conditions (i.e. the entire lifting operation is performed centered in front of the body, the lift is performed between mid-thigh and elbow height, the load is intended for manual handling, each lift is followed by a two-minute rest, the load is not carried, the foothold is stable, and the climate is appropriate).
Lifting within the middle ⅓ part of the yellow area, the amount and degree of aggravating factors determine whether the manual handling is harmful to health – and to what extent it is harmful. Lifting within the bottom ⅓ part of the yellow area, it usually requires several aggravating factors for the manual handling to be harmful to health. In some cases, one single aggravating factor, e.g. the working posture, may cause lifting within the bottom ⅓ part of the yellow area to be harmful to health. Green area : Lifting within the green area is usually not harmful to health based on the load weight and reaching distance. There may be additional risk factors, which are individually harmful, causing the manual handling to be harmful to health, e.g. poor working postures, a high lifting frequency, or an excessive overall strain on the body.
