Basic parameter characterizing the body's workload (in particular physical work) is the energy expenditure, which determines the amount of energy used to perform a specific job (in kcal or kJ). The purpose of this work was to determine the energy expenditure at the station of a water-cutting machine using the tabular-timing method according to G. Lehmann. As part of the author's own research, the position of the waterjet operator was described, taking into account the basic hazards present in the work environment and the requirements regarding occupational health and safety. The paper also presents the results of the energy expenditure assessment and their analysis, which allowed to propose corrective and preventive actions.
