Ss73-04 Methodological Proposal for an Articulation of Ergonomic Design and Ergotoxicology Approaches – The Case of Metal Additive Manufacturing

The aim of this presentation is to propose a global approach articulating design ergonomics and ergotoxicology, in order to support the creation and transformations of future additive manufacturing activities. This approach, developed as part of a thesis, is marked by an Industry 4.0 context. Indeed, this 4th industrial revolution favors the integration of new technologies, particularly digital ones, in order to respond to technical limits and feasibilities, as is the case with additive manufacturing. The methods and approaches used to design technological systems in the industry of the future are mainly based on a technocentric approach. This technocentric design approach often underestimates the multidisciplinary, anthropocentric approaches that enable awareness of real work issues and emerging risks. Indeed, work activities are transformed and new exposure situations arise. The aim of this research work is therefore to create a design methodology for these technological systems that incorporates ergonomics input. This contribution is characterized in particular by the classic methods used in ergonomics: observation of real-life work, interviews with actors, or physiological measurements (e.g. cardiofrequencemetry). The classic ergonomic tools used in project management can thus be combined with ergotoxicology-specific metrology methods: video exposure monitoring, real-time particle measurement, individual aerosol sampling, surface sampling, etc. These data from real work activities will be used to build future activity simulations, prevent occupational risks (MSDs, chemical risks) and support those involved in transforming their professional practices. Knowledge of work and exposure is then used in the industrial design process to promote safe implementation.
