Cutting permanent door sheet in API 650 Tank that is no longer in service
Cutting permanent door sheet in API 650 Tank that is no longer in service
(OP)
My site has an existing tank that is no longer used and the HAZMAT team would like a small door sheet like cut out for training purposes. This would allow the HAZMAT responders to perform rescue attempts in confined spaces with supplied air. The question I have is how do I determine the allowable size for the cutout with proper documentation? API 653 has a section for door sheets but they are considered temporary openings. Any suggestions for calculations would be greatly appreciated. (i.e. reinforcement calculations for cutouts like you would do in ASME Sect VIII for nozzles?)

If you want it to be typical of door sheets used in actual tanks, those door sheets are variable in size, depending on the equipment that needs to pass through. If you want the opening typical of manways or flush manways in tanks, see API-650 for dimensions.
