OSHA anticipates conducting 20 to 30 percent of all inspections as programmed inspections. The agency conducts programmed inspections using national and local emphasis programs that direct resources to high-hazard industries or specific hazards that lead to severe injuries, illnesses, or death.
OSHA currently has 12 National Emphasis Programs (NEPs) focusing on combustible dust, fall prevention, hazardous machinery in manufacturing, outdoor/indoor heat, hexavalent chromium, lead, process safety management, silica, trenching/excavations, primary metal industries, warehousing/distribution operations, and shipbreaking. OSHA’s Regional and Area Offices also have additional Regional and Local Emphasis Programs (REPs/LEPs) that focus on hazards and industries prevalent in their jurisdiction.
Note: On April 10, 2026, OSHA issued a revised Heat NEP, CPL 03-00-024, overhauling the list of targeted industries and making other changes to the program, which will run five more years. On June 27, 2025, OSHA issued a revised NEP on Amputations in Manufacturing Industries, CPL 03-00-027, updating the list of covered industries and making other changes. This program too will be active for five more years.
Site-Specific Targeting (SST) program
The SST program is also a programmed inspection program. It uses objective data from injury and illness information (that non-construction employers submit under 29 CFR 1904.41) to determine which establishments to inspect nationwide under the program. The purpose is to direct enforcement resources to those workplaces with the highest rates of injuries and illnesses.
The agency selects random targets of non-construction, non-office, non-government workplaces (with 20 or more employees) that are either considered:
- High-rate establishments — Those with the highest rates of injuries/illnesses based on data electronically submitted per 29 CFR 1904.41 for a given year; or
- Upward-trending establishments — Those with rates above their industry’s national average in a given year that continued to trend upward in two following years.
To verify data reliability, OSHA also visits a random sample of establishments with low injury/illness rates or that failed to submit 300A data for a given calendar year. SST inspections are comprehensive safety and/or health inspections in scope. During an SST inspection, agency officers will review OSHA logs for the previous three years. The directive also allows records-only inspections when an officer determines incorrect data led to an establishment’s inclusion in the program.
Each SST program directive typically lasts a year or two. However, OSHA has frequently replaced the directive with a new one when the current one expired.
Voluntary Protection Program (VPP)
It’s worth noting that VPP participants are exempt from OSHA programmed inspections while they maintain their VPP status. The VPP recognizes employers and workers in the private industry and federal agencies who have implemented effective safety and health management systems and maintain injury and illness rates below national Bureau of Labor Statistics averages for their respective industries.
To participate, employers must submit an application to OSHA and undergo a rigorous onsite evaluation by a team of safety and health professionals. Union support is required for applicants represented by a bargaining unit. VPP participants are re-evaluated every three to five years to remain in the program.
Small employers in low-hazard industries
An Appropriations Act from Congress can include exclusions and limitations (also referred to as “riders”) that limit OSHA’s authority for using such funding. In providing funding for OSHA, Congress has typically included riders each fiscal year that place restrictions on OSHA’s activities regarding two categories of employers:
- Small farming operations, and
- Small employers in low-hazard industries.
OSHA directive CPL 02-00-170, “Enforcement Exemptions and Limitations under the Annual Appropriations Act,” provides more information. Frequently asked questions are also offered in the CPL.
Let's focus on the "small employer in low-hazard industry" rider. It applies only if both of the following criteria are met:
- An employer has 10 or fewer employees currently and has not had more than 10 employees at any time during the previous 12 months; and
- The days away, restricted, or transferred (DART) rate for the employer's industry is currently below the national DART average, per the most recently published Bureau of Labor Statistics data.
OSHA officials say that the “10 or fewer” number is not for a company but for a single location. A table listing the industries that qualify for limited enforcement activities is found in a link provided in CPL 02-00-170. The list changes each year.
OSHA cannot conduct “programmed” inspections for “safety hazards” at qualifying sites, but the agency may perform “health hazard” inspections whether programmed or not. The agency may also perform non-programmed safety inspections. Finally, OSHA may conduct certain referral inspections. See Appendix A in CPL 02-00-170 for an at-a-glance reference table.
