Hi,
I have just recently started my new job and the previous safety officer used the Red, Yellow, Green labelling system for vibrating tools. ie. Red = 53min yellow = 2hrs and green = 8hrs.
I am unable to get in contact with the person, but can someone please outline to me why this system (as its commonly used)has such a large gap between 2hr yellow restriction and 8hr green?
In my previous job there was no HAVS Risk, so this is new to me.
Many Thanks

I take it you're the new Safety Officer BOD?
Seems like you'll have some work on your hands unless you can find the supporting risk assessments which validate these figures!
Traffic light systems are fairly common and are used by hire industries, but do not in themselves determine an overall safe system of work.
Some further reading for you at

I suggest the HSE ready reckoner system is well worth a look.

We use a similar system and make use of the HSE ready reckoner table online. The traffic light system is what YOU decide it to be. There are no hard or fast rules and the colour system is subjective. You could assign different figures depending on whether the ELV or the EAV were being met.

Hi All,
It appears that the system is in place so I am going to have to roll with it!
What they have done is sourced the manufacturer's ratings and added 100% to take into consideration the real life conditions, then given each machine a label and following the early consulation this didnt cause a problem with the engineers. However one of them has asked me why the jump from 2hrs to 8hrs.
I suppose realistically and I have asked the engineers involved that rarely would a machine be used for more than 2hrs (trigger time) in an 8hr period. It hasnt caused any problems as such its just a query from a inquisitive engineer.
Thanks

Your (inherited) approach may be fine as an interim measure, however I suggest that you should be doing more work, at least on the identified high risk (i.e. Red) tools and processes. Depending on your industry, there are some tools out there with allowable trigger times as low as 15 minutes (measured value). Try also the Karla or Operc websites for more definitive data.
