Dangerous occurrences are near-miss events; however, not every near-miss
event must be reported
Here is a list of some of the common events that are reportable to HSE online:
collapse or partial collapse of a scaffold over five metres high, or erected near water where
there could be a risk of drowning after a fall;
collapse, overturning or failure of load-bearing parts of lifts and lifting equipment;
electrical short circuit or overload causing fire or explosion;
plant or equipment coming into contact with overhead power lines.
dangerous occurrence at a pipeline;
explosion, collapse or bursting of any closed vessel or associated pipe
unintentional explosion, misfire, failure of demolition to cause the
intended collapse, projection of material beyond a site boundary,
injury caused by an explosion.
dangerous substance being conveyed by road is involved in a fire or
road tanker carrying a dangerous substance overturns, suffers serious damage, catches fire or
the substance is released;
failure of any freight container in any of its load-bearing parts;
accidental release of a biological agent likely to cause severe human illness;
dangerous occurrence at a well (other than a water well).
There is also a requirement to notify a range of other serious events associated with fairground
equipment, the collision of a train with any vehicle, the failure or endangering of diving equipment
or the endangerment to a diver, and the failure of industrial radiography or irradiation equipment.
