OSHA 10 Jobs in Denver, CO

OSHA 10-hour certification is a baseline construction safety credential — a 10-hour course covering hazard recognition, fall protection, electrical safety, and personal protective equipment. In Denver, CO, employers requiring OSHA 10 are typically in commercial construction or mechanical contracting, where HVAC technicians work alongside other trades on job sites subject to OSHA 29 CFR 1926 construction standards. The credential is valid for life (no renewal requirement), and the course is available online or in person.

OSHA 10 is available online through OSHA-authorized training providers in formats that can be completed in two days, making it accessible for working technicians who can't leave the jobsite for a full week. The card issued upon completion has no expiration, but some general contractors and project owners now require refreshers every three to five years — check the specific employer requirement when applying. Technicians in Colorado who have OSHA 10 and are pursuing commercial work should also consider whether the next role they're targeting will require OSHA 30, as the upgrade takes roughly three additional days of instruction.
