    Do you educate yourself or pay experts, if your project has a problem related to other field?

    I guess it is a cost/time vs. importance/urgency issue. Whenever faced with something similar, I tried to educate myself either by talking with my mentor, or other experienced engineers. This forum is also a source of high quality information coming from experienced engineers.

    How to make sure I get training, improve my skills on the job, etc?

    What you could also do is to glue yourself to a senior engineer and try to learn from him as much as possible. You could also research some interesting topics which you are interested in and discuss them with your mentor.

    where should the spectacle blind be placed ? before valve or after valve?

    I agree with itdepends. In the PIDs i have seen/reviewed the spectacle blind is placed on the nozzle of the vessel. if there is a spectacle blind for positive isolation somewhere in the PIDs, then depends on the equipment/section/process that you intend to isolate. regards, Vlad
