Is the title a mistake? Perhaps it should say 'Bring Reinforcements……'. The error is intentional to make an analogy that good communications are essential when developing safe systems to avoid mistakes which might lead to failures. There have been laudable endeavours over the years by many safety engineers showing how improvements across the spectrum of system safety can advance our understanding of system safety. Some initiatives may not have delivered what was hoped for, but we should be proud of those that have genuinely advanced system safety. Yet despite these advances, mistakes are still made, often in areas that should be well within our understanding. Perhaps 'reinforcements' were needed but what was received was 'three and fourpence' and resulted in a failure or 'going to advance'? This paper looks at issues experienced by the author. These include technical failures, like the battery charger fires on Dreamliner, or management failures like poor safety culture or inadequate processes and of course, poor communications. They demonstrate a need to get the basics right, learn from the mistakes of others, whilst keeping abreast of new developments in safety engineering. Most important is the need to ensure communications are effective across management levels, other domains, and stakeholders. It’s our role as safety engineers to avoid miscommunication and achieve a common understanding
