With people having cellphones with them 9 times out of 10 here, I find that writing your cell No. on the back of the tag helps a lot.

Spock,
Good call on the use of "Out of Service" tags.
If these were used and used properly and actually taken notice of, I'm sure that a few workplace injuries could be prevented.
One thing that I don't think is widely known (at least it isn't here in NZ),is the fact that anyone can fit these tags, wether they be a maintenance team member or a Labourer.
Only a service-man can remove them after the correct repair has been undertaken.
