A job is designed to create a product or service.  Products examples are:  airplanes, cars, computers, boats, washing machines, or vacuums.  Service examples are:  accounting, cooking, nursing, painting, or repairing.  Many job overlap, but each job as specific requirements to complete the task and produce the product or provide the service.

Job activities are often considered by ergonomic activities.  These include:  forcefulness, adverse posture, repetition or continuous activity, duration of exposure, temperature, vibration, and use of gloves.

The CtdMAP considers these ergonomic (extrinsic workplace stressors) in calculating a Job Risk of 1 low and 7 high base on the RULA.  The Rapid Upper Limb Assessment (RULA) method was been developed by Dr. Lynn McAtamney and Professor E. Nigel Corlett, ergonomists at the University of Nottingham in England.  RULA is a postural targeting method for estimating the risks of work-related upper limb disorders.  A RULA assessment gives a quick and systematic assessment of the postural risks to a worker.  The analysis can be conducted before and after an intervention to demonstrate that the intervention has worked to lower the risk of injury.  Additional question were added to include the lower extremities and back.  Job Risk in also modified by the Ergo Assessment Form that use quantitive data to assess job risk.

Using the CtdMAP Job Risk, employers can compare similar jobs to develop reasonable and appropriate job interventions and medications to reduce risk cost effectively.
