QEC Action Levels
Robert Brown at The University of Sunderland has recently suggested some preliminary 'Action levels' for the QEC system, based on the assessment of a variety of tasks using both the QEC and the RULA, and comparing the exposure scores obtained from both tools. More information can be found in Brown and Li (2003).
QEC total
exposure score*   
Actions suggested   
Equivalent
RULA scores   
Less than 40%: Acceptable                         1-2
41-50%:        Investigate further                3-4
51-70%:        Investigate further and change soon 5-6
More than 70%: Investigate and change immediately  7+
Note: * The exposure level is calculated as the rate between the actual total exposure score X and the maximum possible total Xmax. For manual handling tasks, XmaxMH=176; for other tasks, Xmax=162. Please refer to the QEC Exposure Score Table for further details.
