Moke is right. Some people don't have the temperament to do this work. You should definitely take this career for a test drive before you commit, which is the best thing about taking road jobs, since they give you the opportunity to try it without being stuck in a job you hate.
As for additional certifications or training, ALL training can be useful. However, the reality is that to do well in this business, there is no substitute for EXPERIENCE. The CHP initials look good on paper, but I've seen CHPs that didn't have the experience to be CREDIBLE, regardless of how many times they've read something in a book. Another thing to consider is that depending on your degree, you might not be qualified to sit for the CHP exam yet. ANS is pretty picky about who they let in to their club.
The other thing to consider is that even if you are a CHP and a degreed HP, you will still be a junior tech until you get enough time in to meet the ANS/ANSI standard. I was in the same boat; a degreed junior pulling trash for several years because I didn't have time in grade (Actually, those were the BEST jobs because they were FUN). Now I'm an HP trainer, who unfortunately CAN'T let certain people do independent work regardless of quals or ability because of that same standard, and the reason is that HP work is different than most professions; you CAN'T learn this in a book, only by sweating your butt off in containment, covering 2 or 3 jobs at once and trying to keep track of your problem child insulators or whoever (no offense to those reading!!!) while some psycho HP supervisor keeps paging you to micromanage some other job. . . get the drift? HP work is like educated babysitting. . . you are there to protect the workers, but along the way you need to know ALOT about ALOT.
The best advice I ever got was to learn from all the folks on the road. Some of the smartest people I've ever met were while we were covering generator jumpers at two in the morning in the middle of nowhere. . .
The good techs will take you under their wing and give you a real education. The bad ones. . . well, you'll figure them out real quick. Trust your insticts and learn what you can.
But most importantly,
HAVE FUN DOING IT.
Good Luck!
