Safety First is a cancelled episode of Jack and the Sodor Construction Company.
Characters
Trivia
- This is the fifth known episode to be cancelled.
- The expression "Safety First" is used quite often in the Jack and the Sodor Construction Company series, so it would make sense for Jenny Packard to appear, as she is the one who tells this to her machines.
