    Is there any (international) standards covering permit to work systems and related activities, such as isolations, hot work, etc.

    If there isn't one what is the basis for the system(s) you work with, Dupont?

    @MattD2 There isn't an international standard that I know of. Our company works with the three biggest fuel companies in New Zealand (International and National companies) and they all have their own system, which have some similarities, though many differences.

    For our internal permit to work system, that we apply to our customers without their own PTW system, we closely align with one of the customer systems.

    Here is a good reference: https://z.co.nz/ptwinfo

    Thanks for the reply @Chris Anderson - that is where my digging has got to too. Seems like there is common process in the petrochemical industry on PTW, which is why I originally mentioned DuPont as they seem to be one of the leading players when PTW systems were becoming common place. These also seem to have been adopted to certain extents by medium industrial / manufacturing companies. But then there are some widely different processes by other industries (such as NZ electrical generation/transmission).
    With it being common in NZ for contractors to work over a large variety of industries I do feel for them having to be up-to-speed on multiple processes for the same type of work depending where they are... and no wonder it can be a struggle to get some contractors to "follow the rules" when it can be completely different to what had been ingrained in them depending on where they have spent most of their time... however as for solutions, I do not have any just right now unfortunately.

    I have searched my database and found the following. Some are ancient and some are reports of events. Two in bold are joint Australia/NZ standards and may be relevant and available.
    There used to be a common permit system in Taranaki for the oil & gas industry.
    Hope that's some help

    Thanks Chris - some good references there. Yes I was aware of the regional permit system for the petrochemical sites in/around Taranaki - do I understand you correctly that this is no longer in use (it's been a good 4 or so years since I have looked at it)?

    I cannot speak to the current status of the Taranaki common permit. I knew about it 2000-2003 when I was the corporate Risk Manager for what was then Natural Gas Corporation. Your knowledge is therefore more up to date than mine.
    Maybe someone else in the forum with current knowledge can comment?

    The common permit system is still up and running in Taranaki. Not sure who is overseeing it these days with all the changes in field ownership etc over the last few years.
