Basics of Ergonomic Evaluation


Ergonomic evaluation should be preceded by identification or analysis of potential risks by developing a baseline questionnaire that should have some points listed below which can be referred to the workplace conditions and terms of the task for ergonomic assessment.

Basic Points of Ergonomic Evaluation:
  1. Environmental conditions: Noise, vibration, temperature, humidity.
  2. Temporary Conditions: clockwise, pauses, turns.
  3. Social conditions in the enterprise: organization, distribution of work, return requirement.
  4. Terms of information: Orders, instructions, worker participation.
  5. Energy demands.
  6. Postures, movements versus applied forces at work.

In any case, this basic level of identification or analysis of potential risks is difficult to dissociate from the assessments of working conditions of temperature and humidity status of each position and psychosocial factors, as in the analysis of ergonomic evaluation according to the elements described above, there is a clear impact of ergonomics in other disciplines. But perhaps the question would be whether such conditions have been assessed, whether under the title of ergonomic assessment or under another heading, hygienic or psychosocial. In any case each of the points will get a response from the evaluator.

Therefore, for small and medium businesses grouped after all jobs in the company under similar related tasks, job design and environmental conditions would be necessary, at least, apply an initial checklist risks. If as a result of the implementation of this list item is a brand in a paragraph should be passed to the ergonomic assessment phase and following the method used for the paragraph in question. If not check any of the items in a section is considered that the situation is acceptable and would not be necessary to pass the evaluation stage itself.

Note a common baseline identification and advanced level of evaluation:

Both the baseline ergonomic evaluation and in the advanced level, there are common issues that have to be included in the contents.
a) The obligation to inform and train the employee: In all cases it will be essential once the risk assessment and set the appropriate preventive measure, the worker is informed about it and was trained in methodology and standards of conduct to follow to avoid the materialization of it. We refer to a specific assessment of the workplace from the ergonomically.
b) On medical examination must be taken into account:
  1. It will be necessary to assess whether under Art.22 No 1 of the Law on Prevention of occupational risks, medical examination is obliqatorio character as, "... is indispensable to evaluate the effects of working conditions health of workers or to check the health status if worker can be a danger to himself ...".
  2. The inspector will request that medical protocols are applied in appropriate medical examinations, and must always consider the ergonomic risk to which a worker is exposed concrete.
  3. It can also be advisable to make an epidemiological group of workers who are subjected to working conditions harder or discomfort from the ergonomic point of view, or that generate a greater number of sick absenteeism or work, when the magnitude of risk advice.
c) To be obtained from the employer if there WORKERS especially sensitive in the workplace, and possibly require the rigorous application of Law. In this sense it is advisable to inform workers that in case of pregnancy specific preventive measures should be determined in each case that the prevention service of the company.
d) Check whether there is a participation and consultation of workers in both the development of risk assessment in the adoption of preventive measures.
