Wastewater operator continuing education

Permit-Required Confined Space Entry

Training certificate — California requires no renewal hours

Wet wells, manholes and tanks are where operators die, and too often it is the person who goes in to help. This hour covers the permit, atmospheric testing (especially hydrogen sulfide), the rules, and planning the rescue before anyone enters.

Course summary, as it appears on your certificate

To equip wastewater operators with essential knowledge and decision-making skills to safely perform permit-required confined space entries, prevent fatalities particularly of would-be rescuers, understand atmospheric hazards (especially hydrogen sulfide), regulatory compliance requirements, and proper rescue planning.

Level 1 — what it is and why — the foundations, for operators new to the subject or wanting a refresher

AquaCert does not mark its own homework: a licensed operator reviews the content and the course cannot be sold while that review is out of date.

One hour of study is one hour of credit. Your certificate reports the hours, which is what California records against your renewal.
