Henry was puffing along when he suddenly collided with a truck. Henry thought it was very dangerous and later Kevin explains about "health and safety". Henry set off and it was not long before he spied a "health and safety hazard". A log had toppled off of a log car and onto the track. Henry collected Rocky and the log is soon moved. A bit later, Henry saw Percy broken down on the line. Henry gets Rocky to move Percy too! Then the Fat Controller arrived; he was cross as Henry took Rocky without asking and Henry realises that good health and safety means asking permission first.
