Industrial facilities have at times made many costly mistakes when interfacing with local communities. Risk characterizations comprising risk experts’ probabilistic risk assessments may be technically competent, but not wholly objective, nor do they capture all dimensions of risk that matter to members of the public. When confronting publics and stakeholders who are concerned about a risk, a competent probabilistic risk assessment may not be sufficient to allay fears and concerns. This chapter explains why and describes best practices for public and stakeholder engagement. It argues these should guide practice when industrial facilities managers interact with the public. It also highlights customary simplifications and misunderstandings that can worsen conflict. Over the past thirty years social scientists have studied and learned about how to effectively engage publics and stakeholders in risk decision making. Management would be wise to invest in the capacity to interpret this literature and employ its recommended solutions.
