Before expiry
Plan renewal before mobilization. A site or employer can reject an expired certificate even when the rest of your profile is ready.

H2S Alive Renewal and Expiry
Current Energy Safety Canada H2S Alive certificates commonly display an expiry three years after completion. Check the expiry printed on your own verified certificate rather than relying on memory.
Verify the actual record
Use the issuer’s certificate record and the expiry shown on your credential as the source of truth.
Keep hiring data current
Update the credential and expiry in WrenchRoster after renewal so employers do not screen against an old date.
