Why near misses are the valuable ones
An incident tells you something already went wrong. A near miss tells you the same thing at no cost, with the added advantage of arriving before the consequence. A cleaner who found a fire door propped open, a wet patch under a leaking unit, a loose stair nosing or a light out in a stairwell has given the building information that no scheduled inspection would have produced that week.
Cleaners are unusually well placed to notice these things because they attend every part of the building regularly, at hours when nobody else is present, and they look at surfaces rather than past them. That value is lost entirely if the reporting route is unclear or if reporting is treated as complaining. A contractor whose staff say nothing is not a contractor with a safe site.
