PErforM for work teams Insert presenters names and titles
Manual tasks Manual tasks risk factors
DVD- No sprains, big gains
Meaning of hazardous manual task “ Means a task that requires a person to lift, lower, push, pull, carry or otherwise move, hold or restrain any person, animal or thing that involves one or more of the following: (a)repetitive or sustained force (b)high or sudden force (c)repetitive movement (d)sustained or awkward posture (e)exposure to vibration.” [Schedule 19 - Dictionary ]
Manual tasks related injuries Single, one off exposure: –due to maximum exertion or over load incident –quite rare. Repeated exposure: –ongoing wear and tear –variety of risk factors –more common. Combination of both of the above.
Risk factors: Force Greater force - greater risk. Speed and jerk. Factors that increase effort.
Risk factors: Working postures Awkward. Static.
Risk factors: Mechanical vibration Whole body vibration –vibration is transmitted through the whole body Hand/arm vibration –vibration is transferred to the hand/arm via eg use of a vibrating tool
Risk factors: Duration Time taken to perform the task once or repeatedly without a break. Amount of time exposed to a risk factor. Photos: Daryl Dickenson
Risk factors: Repetition Short cycle time < 30 seconds. Continuously for one hour.

PErforM task - worksheet 2
Scenario – lifting lid on pre-heater box Worker exerting force and awkward postures to lift the lid on the pre-heater. Lid was: catching on the lip of the pre-heater resulting in forceful jerky movements heavy and awkward to lift.
Risk assessment - before
PErforM team control measure Sun Metals reduced the forceful exertions and awkward postures by repairing the lid so that it no longer caught on the lip of the pre-heater. By putting a hinge down the middle of the lid it can easily be opened from each side. Pre-heater with lid cut in half and hinges installed. Worker opening pre-heater with lid cut in half and hinges installed.
Case study - control
Elimination Engineering Hierarchy of control Elimination Work teams are trained to use control the hierarchy to eliminate or reduce risk
Hierarchy of control Substitution ? ? Isolation
Administration J ob rotation Change of workflow Task specific training Preventative maintenance program Personal protective equipment Team lift
Risk controls Developing control ideas: link the control to the risk factor consult with workers and others look for different ways look at similar tasks for ideas find out what are others are doing talk to suppliers trial before implementation.
Focus controls on sources of risk: Change design or layout of work areas. Changing the nature, size, weight or number of persons, animals and things handled. Systems of work. Work environment.
Work area design / layout Good design includes: –suitable working heights –adequate space –frequently used items in easy reach –adjustable to suit all workers.
Changing the nature, size, weight or number of persons, animals and things handled Consider: –load handling –tools and equipment –maintenance.
System of work Guidelines include: –control work load –suitable work pace –task variation –maintenance schedules –match task demands with workers’ capability –training.
Work environment Vibration exposure. Cold conditions. Heat and humidity. Windy conditions. Floors and surfaces. Lighting.
Consider: –short term –medium term –long term. Maintain ongoing communication and participation between workers, supervisors and managers. Implementing controls
To ensure: –controls are working effectively –risk factors have been reduced –another hazard or risk has not been created. Monitor and review
Where to from here? Ongoing risk assessments. Communication with managers. Controls.
