Purge

Purge is the standing public record of a national gas safety registration and enforcement body — the statutory register every gas business and engineer must be on to work legally, and the machinery behind it. The register of businesses and the engineers working under them; competence scope categories by appliance and work type with their assessment certificates and expiry; notification of notifiable work; the inspection programme that samples completed work and grades it; the unsafe-situations procedure with its three classifications — Immediately Dangerous, At Risk, Not to Current Standards — each with its action, warning-notice serial range and disconnection rule; reportable gas incident investigation; annual reassessment of competence; the sanctions ladder and its committee; public reports of illegal or unsafe work; technical bulletins; the annual statistics return; and a registered engineer's portal carrying their registration card, scope list, expiry countdown and inspection history. Built in the ISO 7010 / BS 1710 industrial safety-signage idiom: placard blocks with corner serials, hazard banding, pipe-identification colour bands carrying the navigation, stencil display type and tabular monospace numerals, every pictogram drawn as inline SVG.
