Part of the problem is that "speeding" is a very subjective thing.
For example, stick a "10kph" speed limit sign up and what does it mean? Cars, for a start, struggle to show 10kph on the speedo. Then how do you know if a person is actually going over "10kph"
So we ignore our 10kph speed signs (its purely a guide for visitors). We never had speed humps. We don't do tool box talks.
What we do do, is on Induction people get the message "Don't go faster than 10kph - or about walking pace" That's about it.
Do we worry about the "10 kph? Part? No. This is just said to give those who like targets something to aim for.
Do we figure most people understand what "walking pace" is. Yup - its what slow and fast walkers do. And its close enough.
Does everyone speed? No. So no point making a blanket "rule" to cover the 99% of people who understand what walking pace (or thereabouts) is.
And where is the "speeding". If its among parked cars its a potential problem. If its by the gates, not so.
So what do we do with the "speeder". We take them aside and say "pull yah head in - you are going to fast". Now you'll see the advantage of not having a 10kph limit - it stops the litigious argumentative types coming back and saying "what proof do yah have of me going more than 10kph". They might say " I wasn't going fast" - to which our response is "Well you were going faster than Freddy who was walking by at the time. So slow down"
The person inevitably slows down. And we havent had to take the issue any further. If we did it would inevitably follow a "discipline" process.
The problem we have most often is with couriers. On those occasions we ring the courier company and tell them to get their drivers to slow down. And this invariably works. On one occasion we had to say if there is no change then we will change couriers - that brought about an immediate improvement.
Sometimes all you need to do is have a word with the single offender. This afternoon I've got to have a wee chat to a guy who seem to think its OK for him to ride his skateboard on site. No need for a "No Skateboards" rule. Just a quiet word to a twit.
