Source Records and Check Dates

This page lists each public document behind a fact on this site, one entry per document, with its publisher and the date it was checked. Only confirmed records appear here, and a fact the publisher's own page did not confirm appears on no page.

The records come from 5 kinds of publishers: local governments and utilities, Washington agencies, federal agencies, standards and industry groups, and manufacturers. Examples are the City of Edmonds, Washington L&I, US EPA, the IICRC, and Teledyne FLIR. No marketplace, directory, or company blog is used for a fact.

Time-bound records, such as permit handouts, claim rules, and standard editions, carry a 6-month recheck, and the rest carry a 12-month recheck. Every date below was set on October 30, 2026, so the first rechecks fall on April 30, 2027.
