Will color blindness prevent me from working as a process operator?

I found out 8 years ago while taking a physical that i was red/green color blind and/or deficient. I passed all but 2 cards on the Ishihara Test (find the number in the dotted circle). Does Anyone know if this will disqualify me from working as a process operator, or any other related field, in any of the big refineries or chemical plants? I graduated with P-tech Degree in 2008 and have yet to get to the point in the hiring process to find out. Any company specific information would be greatly appreciated.

Thanks

Do not make it an issue, don't offer the info if not asked. You do not need color vision to be a good operator. I have been a refinery operator for 3 years, and I am color blind. No one ever asked, and it is not important. Knowledge of valves and line-ups more than make up for any deficit of color vision.
