Tables of Risk comparisons

Most tables of risk comparisons in the literature contain a mix of risks characterized by different levels of uncertainty. In addition, most risk comparisons in those tables offer only single number risk estimates, with no range or error term. For risks such as driving, where fatalities can be counted on large samples, the number is likely to be reliable, at least in some countries. However, even if the risk comparison data are carefully and accurately reported, they can be misleading.…

Catastrophic failures forensic analyses

Catastrophic failures forensic analyses are, most of the time, left in the hand of experiences engineers. At least, that’s the case for tailings dams failures and other catastrophes like major infrastructural accidents and for instance, aviation. Are we sure that is the best way? Normalization of deviance, management and decision-making are oftentimes ingredients of the catastrophic failure buildup, not only “engineering”. So, we dare to say, Independent Panels should include social scientists. They seem to be the most qualified to…

Quantifying Tailings Dam Risks at MIRA

Quantifying Tailings Dam Risks at MIRA (Mining Insurance and Risk Association) one hour session took place on June 11th 2020. The talk presented a comprehensive approach to address how to quantify and prioritize tailings dam risks, especially in the context of large dams’ inventories. In this blogpost we summarize the Q/A session that followed the talk, classified by theme. The full talk is viewable on Youtube    At the end we present a synthesis before some closing remarks. Understanding geology and…

CIM Tailings Workshop Series comments

Within the frame of the CIM Tailings Workshop Series  pre-workshop comments participants were asked three questions aiming at “feeding” the discussions. Below are the three questions and our “short” replies.  What is a tailings system? From a physical point of view, not in order of importance: start at the pumps in the mill, pipelines, spigots, dam(s), all water management ancillary facilities (including diversions, decants, spillways), roadway at the crown, seepage collection facilities, decant raft and pipes, monitoring, investigations and testing…

Anticipating Objections to risk assessments

Anticipating Objections to risk assessments is paramount to foster social licence to operate (SLO) and corporate social responsibility (CSR). The first step is to avoid any suspicion of conflict of interest. Indeed, risk assessments should be performed by an independent entity (Brehaut, 2017, UNEP). That is to avoid conflict of interest (Oboni, Zabolotoniuk, 2013) and assuage public concerns. Nevertheless, the proponent of a project might feel vulnerable if that information becomes public. Thus, today we discuss how to help remove…

Demands for Zero Risk

Oftentimes when explaining risks to Management or the public “Demands for Zero Risk” objection arise. Repeatedly, stakeholders may point out that any “non zero” risk is unacceptable. Indeed, in the aftermath of any recent accident (Samarco, Cadia, Mount Polley) public opinion, regulators, law enforcement agencies and the media vehemently embrace that vision. However, the first reaction should be to declare that goal  as not realistic as any endeavor has intrinsic risks. Indeed, we are exposed to hazards and resulting risks…

Tailings dam risk communication

Experience shows that successful risk communications always focuses on planned control measures and precautionary actions rather than on risks. Indeed, like in many other fields, actions speak louder than words. Because actions are what matters to the public. Thus, today, we explore our experience in tailings dam risk communication. In mining, oil and gas and other industries, people demand to know what preventative actions are foreseen. That is even if it is claimed that the likelihood of an accident and…

Risk tolerance thresholds

Everyone has a different pain threshold and likewise, everyone has different risk tolerance thresholds. We use the plural because each one of us has various thresholds, for example, a perceived one and a financial one. Your risk and risk tolerance thresholds made simple Anyone of us, every-day decides to undertake some activities and consciously or unconsciously assumes risks we consider acceptable/tolerable or sometimes intolerable.Think about various activities: Hunting, fishing, driving a heavy vehicle, and finally cooking in one’s house. They…
