A comparison of three methods to identify chemicals hazards in French research laboratories

Even if the observations are more burdensome to carry out, they make it possible to understand the complexity of the compromises made by operators when they face risks. In that perspective they can unearth accounts of incidents and strategies that would be otherwise difficult to verbalise through other methods. What is more, such observation methods can also help involve workers in a bottom-up approach and turn them into active stakeholders in the prevention process. It may thus be possible and relevant to develop an articulation between consensus methods and those centred on ergonomics observations.
