OK, so what does this have to do with a safety culture?
Have you done any succession planning to ensure that your plans for an injury free safety culture continue in the event of unexpected (or expected) personnel changes? We don’t live forever, nor do our people stay around forever. What you are doing is too important for it all to come to a sudden end because of an “Aardvark” like event that takes one or more critical people out of action.
A good succession plan is important to termites, businesses and safety cultures. Why not update (create) yours soon.
