This book has for research framework the Gabonese hospital environment and for study population the technicians of the care and the childbirth whose theoretical anchoring articulates around the danger, risk and accident. Indeed, this essay is part of the field of social psychology of work and organizations with an interest in occupational health, a practical and research field that aims to contribute to the improvement of health, the prevention of risks and the protection of hospital workers, particularly care workers.Our thinking in conducting this research in the hospital environment can be summed up by the fact that staff in this environment are exposed to occupational risks. How do they deal with the risks inherent in their work and their professional environment? How do they think about them? What are their representations of risks? How are they linked to their practices? We believe that the characteristics of risk situations and their representation include factors related to the caregivers, the patient, the work environment, the organization of work and the nature of the risk incurred.
