With great pleasure I copy and paste from a similar discussion a few years back, take note of the name at the bottom. If you can pass the test and requirments all you need is as follows.
I don't know who protects the inspector other than the inspector. The best ways to do that:
1) Get the scope of inspection activities defined at the start of the job.
2) Have access to the referenced codes and specifications.
3) Have the attitude that you are trying to prove the work is done correctly, even when you find it is not.
4) When you find a problem, get the foreman (or whoever) to look at it with you see if they see the same thing. "Maybe I'm not looking at this right, what do you make of it?"
5) Never quote the code without a copy of it in your hands.
6)Take digital photos of the problem for a visual record. (BE SURE that you have permission to take photos first.)
7) When you can legally and ethically give someone a break, do so.
8) When you have to report what was wrong, be sure to include what was right. But just the facts, no opinions unless asked.
9) Get everything in writing and give everything in writing.
10) Admit your mistakes without any "Yeah,buts".
11) Don't fight battles. Send them up to the next level, and accept the findings.
12) Keep records of everything you do or say.
13) Recognize that there are some things you have no power over and many times that you don't have the full picture.
14) Don't let one bad experience spoil everything. There are better days ahead.
15) Maintain your integrity.
16) Remember that we never stop learning.
Others may have things to add, and I hope they do so, but you are your own best advocate. It would be nice if there is a group or agency to look out for inspectors but I have not heard of any. We all pretty much stand on our own merits, and your sense of justice indicates that you will build up a fine reputation.
