A Fuel Smell in a Kindergarten Store Room: The Cause Was a Tank Cap Seal Nobody Had Ever Replaced
A fogger sitting idle can still be dangerous, if the tank cap seal has perished and fuel vapour is accumulating in a closed room near classrooms.

This article tells the true story of a kindergarten that found fuel vapour accumulating in a store room adjoining the corridor to its classrooms, and explains why this matters and how to prevent it.
