Providing warnings and accuracy features on map for legal reasons - Essential?

Question

I work in a big corporation and one of my many responsibilities is making maps for field-workers. I usually make them very basic maps, as they know what infrastructure to look for, they just need the basic road directions, and they know what rate of accuracy our data is in. As a one-time assignment, My boss asked me to make a map for a new contractor and as one of the regular features is "dangerous places" (that the field workers should avoid) he said I should write a so-called legal comment on the map that states the user should not rely only on the map and to state the accuracy. And that got me thinking - I know none of you are lawyers, and neither am I, but what do you do on your maps?

Right now, I only put the statement on "outside jobs". Is that a mistake? should I put it also on "inside" jobs? and what's more - Do I have Individual responsibility and can be sued personally, or does my company "vouch" for me?

(moderators: sorry this is not a wholly Q&A as this site requires, but I really want to know what others here do).

UPDATE: the question was more aimed as to ask if the disclaimer is really needed, but versions are welcome as well.

Here's a disclaimer relating to "geospatial data products" that "appear to represent property boundaries", which is soon to be required by law in Texas:

This product is for informational purposes and may not have been prepared for or be suitable for legal, engineering, or surveying purposes. It does not represent an on-the-ground survey and represents only the approximate relative location of property boundaries.
