Handling accidents

What do we mean by best lead time?

The notion of "best lead time" is not defined in either legislation or case law.

The time limit is assessed on a case-by-case basis, depending on the nature and seriousness of the incident or accident.

It is reasonable to consider that a maximum of 1 to 3 days following the incident or accident is a useful period for gathering the initial information needed to inform the authorities.
