Purpose of this library
This library explains tank types, stored liquids, residues and cleaning considerations that can affect the condition needed before inspection, repair or reuse. It provides general technical information only. It is not a site-specific risk assessment and does not give instructions for hazardous work.
Sources and editorial review
Each entry is based on the regulator, public-health, technical or manufacturer sources linked on the page. A source date records when the information was checked for this library, not necessarily when the source was first published. Manufacturer material is limited to the products or equipment it describes, and regulatory guidance applies only within its stated jurisdiction and scope.
A general source is not treated as evidence for a particular tank installation. Construction, previous contents, contamination, connected equipment and intended reuse can all change the assessment. Where an entry gives a numerical rule or product-specific limitation, the stated source limits remain part of that information.
Use of AI assistance
AI is used as an editorial tool to help draft, organise and edit this tank cleaning library. The wording is then checked against the sources linked on each page and reviewed for relevance to the entry. This is an AI-assisted workflow; it is not independent approval by a named chemist, engineer or other technical specialist.
AI is not used to invent qualifications, site visits, case studies, test results, equipment ownership or specialist endorsements. A named technical contributor is credited only when their identity, relevant expertise and review of the actual material have been established.
Full guides and reference notes
Full guides cover a distinct tank type, stored material or residue in more detail. Short reference entries identify narrower applications, construction details or contamination issues and link to the source behind the note. A reference entry does not establish that every cleaning method is suitable for that tank or material.
Corrections and updates
Corrections are checked against the cited source and the technical context of the entry. Review dates change when the content has been substantively checked or corrected, not simply because a page has been rebuilt.
Some questions cannot be resolved from a general library page. Unknown substances, structural defects, confined spaces, incompatible materials and changes to process or water systems need competent assessment for the actual installation. Immediate hazards remain subject to the site’s emergency arrangements.
