When did health and safety become the science of human performance?
British Safety Council’s Hidden Hazards campaign asks us to recognise workplace health risks that are easily overlooked because they are not always visible or immediate. The emerging science of human performance takes that challenge further, and we therefore need to ask: what if some hidden hazards matter not only because they can make people ill, but because they can quietly change how well people think, judge and respond while they work?
