What federal OSHA is targeting in Colorado
Colorado has no state OSHA plan for private-sector work, so there is no state rule to read. What differs here is which hazards federal OSHA schedules inspections for, as set out in published emphasis directives.
Regional Emphasis Program – Noise Induced Hearing Loss
CPL 2022-02 · Denver Regional Office · effective February 15, 2022
“This Instruction applies to all Area Offices in Region VIII.”
The Denver region names the outcome rather than the exposure: noise-induced hearing loss. It covers every area office in Region VIII, so Colorado, Montana, North Dakota and South Dakota are all inside it, and it pairs with the region's silica program on the health side.
Regional Emphasis Program on Silica in Cut Stone and Slab Handling Operations
CPL 2022-01 · Denver Regional Office · effective February 8, 2022
“This Notice applies to Cut Stone and Stone Products operations, NAICS code 327991, located within the jurisdiction of each Area Office in Region VIII.”
Respirable crystalline silica in cut stone and slab handling is targeted by NAICS 327991 across every Region VIII area office. An inspection under this program looks at the exposure assessment, the respiratory protection program and the hazard communication for silica.
Harmful exposures and work deaths in Colorado, 2024
Colorado recorded 92 fatal work injuries in 2024, up from 83 in 2023. Exposure to harmful substances or environments caused 13 of them (14%). Construction accounted for 24.

How Colorado Enforces 29 CFR 1910.134
Colorado has no State Plan, so federal OSHA has jurisdiction. 29 CFR 1910.134 is enforced by U.S. Department of Labor compliance officers using standard federal procedures and the federal penalty maximums.
In Colorado, the FY2025 citations under 29 CFR 1910.134 went most often to Masonry Contractors (1) and All Other Specialty Trade Contractors (1). A single inspection can produce several per-instance citations. Recurring self-audits against 29 CFR 1910.134, before an officer arrives, are the most reliable defense.
Help and oversight in Colorado
Free, confidential help: OSHA On-Site Consultation
In Colorado, the program is Colorado State University (Health & Safety Consultation Program). OSHA describes it as “Primarily for smaller businesses, no-cost, confidential consultations help employers identify and address hazards and establish or improve safety and health programs.” It is separate from OSHA enforcement; the employer commits to correcting serious hazards.
Who inspects private employers here
Federal OSHA, from the Denver Area Office (Denver) and the Englewood Area Office (Englewood).

Colorado Penalty Amounts for 29 CFR 1910.134 (2026)
