You may narrow your search by using several types of filters:

• On the left – general filters, applicable to all types of content available on this website (publications, accident summaries);
• On the right – filters specific to individual accidents. You must first select “Accident” among the types of publications, in the general filters. Then you may select specific filters.

To apply your selected criteria and launch the search, click on “Apply the filters“. To clear all selections previously entered, click on “Reset the form“.

The logic operators used by default are:

• “AND” between the various search criteria
  Example: date = “between 2 and 5 July 2016” & hazardous phenomenon = “fire” –> outputs the list of fires catalogued between the 2nd and 5th of July 2016.
• It is possible to make a research on several words. The defaut logical connection between these words is “AND”. If you want to combine the words with “OR”, tick the box below the textual search field.
• “OR” within a given criterion
  Example: hazardous phenomenon = “fire”, “explosion” –> outputs the list of accidents involving fires alone, explosions alone, and both fire and explosion.

It is advised to gradually narrow your search, i.e.:

• select an initial criterion
• click on “Apply filters” and verify the type of results obtained (number, relevance)
• repeat the operation as needed by selecting an alternative criterion and clicking on “Apply filters”.

If you’ve selected too many criteria simultaneously, some of them might be mutually exclusive, leaving you with no results.
