Terms of Service

Use of this site is on the terms below. They exist to be clear about what published guidance is and what it is not.

Reuse of Content

Content on this site is its publisher's property. Attribution with a link earns a quotation; scraping the page does not.

Not Advice for Your Job

Nothing published here is professional advice. A qualified professional assessing the property in person is the appropriate source for that, and their assessment takes precedence over anything written in advance.

Changes

What appears on this page is the current agreement. Whatever appears here when a reader visits is the operative version.

External Links

External links do not imply any endorsement. It is not because it is vouched for: its content and conduct are its own responsibility.

Accuracy

Reasonable care goes into keeping the content accurate. No guarantee is offered that every statement is correct or current: codes are amended, products are discontinued, and prices move.

Liability

Acting on this material is done at the reader's own risk. No responsibility is accepted for any resulting expense or loss, so far as the law allows.
