The differential value of an ergonomic intervention is to bring an innovative approach in the models and practices of treatment of risks at work, in the assessment procedures and in the models used for data processing. These procedures are based on an approach to occupational health that must be elaborated by the worker and must also be understood as a construction directly linked to the work context. The ubiquitous approach of the ergonomic intervention presented here was developed and designed as a process of specialized knowledge production in the field of occupational health, specifically in the operational field of the activities of an oil company. The objective of this ergonomic intervention was to transfer the practices, models and strategies developed in the laboratory or from the theory to the practices developed by the workers and the company. A flexible structure was developed according to the new models of workers involved in the field of occupational health.
