What's so funny is that, as with all stupid touchy-feely laws, the unintended consequence is that everyone ignores ALL of them, even the important ones.
This led to a bit of an argument when our small company launched our first industrial product. It is an electrically powered machine tool accessory that operates in an environment flush with high pressure coolant. There are some very important safety and performance issues. These are simple and obvious things to anyone who has been around machine tools and included the basics such as make sure tool holder is grounded, check the ground with included ground tester, make sure high pressure line is swaged correctly if you replace the line that is supplied, replacement line must meet original specifications provided below or it can rupture due to excessive pressure and mist can result in significant fire hazard, etc. Simple yes, but ours was an entirely new technology using unique materials and powered differently than traditional tools. Thus, we had a list of the critical, get it right or you'll have a performance or genuine safety issue, stuff.
So we had a half page of REALLY important stuff. When the lawyer got done with the disclaimer it was 5 pages of mostly meaningless crap. The problem, as Jay mentions, is that the important stuff was lost in all the crap. No machinist worth his salt would read through the legalese and our tool looked like any other (except it cost $30,000 instead of $300).
We finally settled on "hiding" all the legal disclosure crap in with the manual and warranty paperwork and had it buried in the bottom of the box. On the TOP of the controller where you couldn't possible miss it (yes, you could still ignore it), we had in large print a statement that the following 6 items where critical to efficient and safe operation of the device. Interestingly enough, our lawyer said it wasn't necessary from a legal perspective. We did it to try and help our customers use the new technology properly.
Not sure how much it really helped. We regularly got calls "it doesn't work, it just breaks drills".
"Did you check the ground like it says in big print on the controller?"
"It's grounded."
"Okay, so it is grounded, did you CHECK the ground?"
"It's grounded to the machine controller 3 prong plug."
"Okay, but we include a ground test, did you actually, physically CHECK the ground yourself to make sure you have a good ground?"
"You mean I need to check the ground?"
"Yup, we include an earth ground tester, it is in the box, plug it in and it will light up if you have a good ground."
"Oh, okay, let me check." ... 5 minutes later "Yeah, the light didn't light up."
"That means you don't have a good ground. You need to check the inverter and make sure you plug is grounded or you can drag over a GROUNDED extension cord."
"Really?"
"Yup, that why we say you need to check the ground, why we provide the earth ground tester, and why it is in BIG PRINT on the top of the controller to check the ground."
"Uhhh, okay."
And this was from skilled, highly paid machinist or engineers. Imagine you favorite local village idiot buying a coffee at McDondald's.
