Here is the collection of OTHEA reports. Please select a sector and then sub-category to view the list of relevant reports. Alternatively, you may search for a word or phrase in the full set of reports.
If an incident happened abroad, some modifications may have have been made to the original report to help a UK audience. You will also find that a few reports are not available in English - this is because the incident and the lesons learned are specific to another country.
