This document is intended to be used alongside ISO/TR 12295, ISO 11226 and the ISO 11228 series in the agricultural sector. This document gives information on how existing standards can be used in a global sector such as agriculture where, albeit with different characteristics, biomechanical overload is a relevant aspect, WMSDs are common and specific preventive actions are needed.

The proposed project aims to:

  1. define the user(s) and fields for its application (including non-experts in ergonomics);

  2. provide examples of procedures for hazard identification, risk estimation or evaluation and risk reduction in different agricultural settings, through:

    1. more synthetic procedural schemes (main test);

    2. more analytical explanations of the procedures, through mathematical models and application examples, also with the use of specific free simple tools, in:

      1. Annex A (pre-mapping with ERGOCHECK);

      2. Annex B (evaluation of Multitask risk of biomechanical overload on typical agricultural macro-cycles, considering upper limbs repetitive movements, manual lifting and carrying, pushing-pulling);

      3. Annex C (study of awkward postures with criteria derived from the actual standards and scientific literature as TACOS method).
