A new publication describes the role of risk management in commercial nanotechnology projects. Risk appetite is the unifying concept. It follows that risk transfer is an essential component when there is uncertainty. The paper identifies commonly available measurements which scale with risk, are (to a large extent) mutually orthogonal with respect to risk, are generalisable across reasonably clear hazard groupings, remain valid when combined into a risk value and can be calibrated against research findings and commercial feedback. The limited set of these will not serve the highly sophisticated precautionary regulatory purpose. Quantitative nano-specific injury risk evaluation for regulatory purposes is still a long way off. In the mean time, risk generators and liability insurers may benefit from a shared approach to nano risks. Such an approach would support the development of expertise. The paper can be read free of charge until 28th May 2017. Included is a link to a free, confident
