The latest accident alerts from Singapore had been improving in its usefulness. The case studies are relatively prompt and have pictures to help readers understand the cases better. The most recent alert can be found here.
Some possible improvements include providing a set of indexes on the case (like what Chemical Safety Board does for its accident reports) to facilitate classification of the lessons learned. A database should be developed to allow public to search for past cases. Perhaps a forum can be created to allow safety professionals to discuss the cases to derive other useful lessons.
