There are many ways to build better awareness than just posting a rule on a tool. You can teach the rule in the class where you gain access to the tool. You can make posters with the particular rule and post them through out the space. You can lead groups that take the time to explain the rule and why it is there on tour nights and other events where you explain the committee area. Best of all, you can note it officially on the wiki to allow the BOD to actually enforce the rule as it now has a date by which it was started and is posted in our official record for the space.
This is incorrect, there are many circumstance by which people can not be aware of work area signage. As the signage can be covered or blocked with dirt or an obstruction and made illegible. The sign can be removed by others either for a proper reason or improper reason. The sign can be made of poor material and just not survive the environment it is in. I’m sure others can think of other possible problems. This doesn’t mean that we shouldn’t put signage on a machine, but just because your took a piece of blue tape and wrote a not once once on the lathe, doesn’t make it a perfect solution, just because there is a sign on the machine.
To be honest it feels like @John_Marlow and @Photomancer are exaggerating very minor issues and claiming them to be major problems. All committees should post rules for their committee areas in the Wiki. Yes, it isn’t the easiest, fastest, or nicest repository for these rules. But, it is the official repository for the group for items like this. Will their be growing pains, yes. Will every committee accept it right away, no. But, should ee try to implement it, YES, Most Definitely.
