Near Misses:

A near miss is an unplanned event that did not result in injury,illness, or damage – but had the potential to do so. Only a fortunate break inthe chain of events prevented an injury, fatality or damage; in other words, amiss that was nonetheless very near. The phrase "near miss" shouldnot to be confused with the phrases "nearly a miss" or "theynearly missed" which would imply a collision. Synonymous phrases to"near miss" are "close call", or "nearly acollision".
