Employers & Specifiers
Before RDS-1:2026 there was no published standard for dry ice blasting operations and no credential a second party could check. This page is how you use both.
Verify before you award
Ask any operator or bidder for the National Registry Number on their certificate or wallet card and check it at the registry — or scan the certificate's QR code. The record shows holder, credential, standard, status (ACTIVE, EXPIRED, or REVOKED), and validity dates. It is the authoritative record: a certificate without a live registry record is not a Revex credential.
What the credential attests — plainly
A DIB credential attests that the holder passed a timed, randomized examination against the published blueprint of RDS-1:2026 at that level. It is a knowledge credential: it does not replace employer-required site-specific training, does not confer US DOL OSHA Outreach cards or HAZWOPER certification, and is not a government license. That precision is deliberate — it is what makes the credential trustworthy.
Requiring certification in specifications
Specifiers may incorporate the standard and its credentials in procurement documents. Suggested language:
"Dry ice blasting operations shall be performed by personnel holding an active DIB credential under RDS-1:2026, verifiable in the Revex National Certification Registry. Work in specialized environments per Clause 10 shall be performed or directly supervised by personnel holding DIB-2 or higher."
The standard's full text is public and citable: see Governance & citation for the citation format and edition history.
Workforce verification & misuse
To verify personnel in volume, or to report a misrepresented or altered certificate, contact the registrar at certs@revexuptime.com. Credentials found to be misrepresented are revoked, and revocation shows on the public record immediately.
