ABSTRACT
This chapter examines and assesses the risk of biomechanical overload due to awkward or tiring working postures among workers at archaeological digs. In this particular analysis, workers were asked to use key enters to judge the issues relating to various environmental and instrumental factors, such as lighting, noise, and availability and adequacy of equipment/tools. Risk indexes are supplied for each month of the year and as a total for the whole year with respect to both mathematical models: time-weighted average and multitask complex. The first step in analyzing the work of archaeologists consists in pre-mapping risk using the method and simple tools developed by Ergonomics of Posture and Movement. The intrinsic indexes for each individual task were calculated using the Occupational Repetitive Actions checklist, assuming a modal day of 480 minutes with two 10-minute pauses and one 60-minute meal break.
