Federal OSHA jurisdiction — no state plan
Missouri does not operate an OSHA-approved state plan. Federal OSHA directly enforces occupational safety and health standards for most private sector employers and workers in Missouri. State and local government workers in Missouri are not covered by federal OSHA, and because Missouri lacks an approved state plan, these public-sector employees have no OSHA protections.

Construction Safety Training Act — public works projects
Missouri's Construction Safety Training Act imposes mandatory safety training obligations on contractors and subcontractors engaged in public works construction. The Act applies narrowly to contractors who enter into contracts with public bodies (state agencies, political subdivisions, or institutions supported in whole or in part by public funds) for construction of public works (fixed works constructed for public use or benefit or paid for wholly or in part out of public funds).
Training Requirement
Every contractor and subcontractor must provide a 10-hour OSHA construction safety program to their on-site employees—laborers, workmen, drivers, equipment operators, and craftsmen directly engaged in construction at the site. The program must be either (1) a 10-hour OSHA construction safety and health course approved by OSHA, or (2) a similar program approved by the Missouri Department of Labor and Industrial Relations that is at least as stringent as the OSHA program. Employees who have previously completed the required program and hold documentation are exempt.
Timing and Documentation
On-site employees who have not previously completed the program must complete it within 60 days of beginning work on the public works construction project. An employee found on a work site without documentation of successful completion is afforded 20 days to produce such documentation before being subject to removal from the project.
Penalties
The contractor forfeits as a penalty to the public body $2,500 plus $100 for each employee employed by the contractor or subcontractor, for each calendar day (or portion thereof) such employee is employed without the required training. The penalty does not begin to accrue until after the 60-day training period and the 20-day documentation grace period have elapsed. The public body awarding the contract must withhold and retain all sums due and owing as a result of violations when making payments to the contractor. Contractors and subcontractors are jointly liable—each contractor is jointly liable for penalties incurred by its subcontractors with non-compliant employees. If the contractor or subcontractor fails to pay the penalty within 45 days following notification by the Department, the Department must pursue an enforcement action to recover the penalty plus its actual cost of enforcement.
Exclusions
The Act does not apply to work performed by public utilities under the jurisdiction of the Public Service Commission or their contractors, or work performed at or on facilities owned or operated by such utilities. It also does not apply to rail grade crossing improvement projects where a signed agreement exists between the railroad and the Missouri Department of Transportation or where an order has been issued by the Department of Transportation ordering such construction.

Missouri state workplace safety laws — scope beyond Construction Safety Training Act?
Missouri does not have a general state occupational safety and health statute, agency, or set of regulations that impose workplace safety standards on private-sector employers beyond its narrow Construction Safety Training Act. For most private-sector workplaces in Missouri, occupational safety compliance is governed exclusively by federal OSHA standards.
Missouri is not an OSHA "state plan" state — it has not adopted its own state OSHA program and does not enforce independent state occupational safety and health standards for the private sector. The Missouri Department of Labor and Industrial Relations (DOLIR) does administer the Construction Safety Training Act (Mo. Rev. Stat. § 292.675), but that law applies only to contractors performing construction on public works projects for public bodies and does not apply to general private-sector employers.
Aside from statutes addressing very specific hazards or workplace activities (such as those regulating explosives, boilers, or public utility operations), there is no comprehensive Missouri law or regulation imposing workplace safety duties on private employers in sectors other than public works construction. In short, private-sector employers in Missouri outside of regulated exception areas (e.g., explosives, public utilities, certain public contractors) look exclusively to federal OSHA for applicable occupational safety requirements.

Workplace safety requirements for state and local government employers
Missouri does not have a general occupational safety and health law that imposes workplace safety requirements on state or local government employers or protects public-sector workers from workplace hazards. Federal OSHA does not cover state and local government workers unless the state operates its own OSHA-approved state plan. Missouri does not do so; Missouri is one of the states that relies entirely on federal OSHA enforcement for private-sector workplaces, and that coverage stops short of public-sector employees.
Specific carve-outs:
- Missouri's Construction Safety Training Act (Mo. Rev. Stat. § 292.675) does impose a job-site safety training obligation affecting public works contractors and subcontractors on contracts with public bodies—that is, construction workers on publicly-funded projects must receive the 10-hour OSHA training—but this duty attaches to the contractor, not to the public body as an employer, and it is a training mandate rather than a general workplace safety standard. The statute does not create affirmative general workplace safety obligations for the government as a public-sector employer, nor does it create a government agency enforcing such standards for government workplaces.
- Missouri statutes do address occupational hazards in very specific areas (e.g., boiler safety, explosives, asbestos abatement in schools), but these provisions are hazard-specific and do not amount to a comprehensive workplace safety regime for all state or local government workplaces.
Result: As of 2026, the practical result is that state and local government employees in Missouri do not have general statutory or regulatory workplace safety protections comparable to those provided to private sector workers under federal OSHA, absent a contract-specific requirement or a limited statute narrowly targeting a particular hazard in public facilities. Missouri has not established an administrative complaint process, enforcement body, or general right for public-sector workers to workplace safety outside these narrow contexts.

Documentation requirements — OSHA 10-hour card validity and out-of-state acceptance under Missouri Construction Safety Training Act
Under Missouri's Construction Safety Training Act (Mo. Rev. Stat. § 292.675), contractors and subcontractors working on covered public works projects must ensure on-site employees can document completion of the 10-hour OSHA construction safety program—or a Division-approved equivalent program that is at least as stringent.
Acceptable Documentation: The most commonly accepted proof is the official OSHA 10-hour Construction completion card (“OSHA card”), which may be issued by any authorized provider in any state. There is no requirement in statute or agency guidance that the card be issued in Missouri; out-of-state and older cards are specifically recognized.
No Expiration/Recency Rule: Missouri’s Division of Labor Standards explicitly states OSHA 10-hour cards do not expire. Any properly issued card, no matter the date or state of issuance—even if the program was completed prior to the law’s effective date (August 28, 2009)—satisfies the statutory requirement.
Production and Grace Period: Employees must be able to produce documentation of completion upon request. If an employee is found on-site without proof, the contractor or subcontractor has 20 calendar days to provide documentation before the employee must be removed from the project and penalties accrue.
Equivalent Training Documentation: For non-OSHA (“equivalent”) programs, documentation must show Division approval. Employers may submit those records for review to confirm program sufficiency.
Summary: Any legitimate OSHA 10-hour card, regardless of age or issuing state, meets Missouri’s documentation requirement. The law imposes a 20-day calendar grace period to furnish documentation if not immediately available.

Missouri workplace-safety whistleblower protections (beyond federal OSHA)
Missouri law provides several state-level whistleblower protections for workers who report unsafe or unlawful conditions—complementing federal OSHA’s anti-retaliation rules (29 U.S.C. § 660(c)).
1. Private sector general whistleblower protection (RSMo § 285.575, Whistleblower’s Protection Act) Missouri’s Whistleblower’s Protection Act, RSMo § 285.575, prohibits employers from discharging or discriminating against an employee (“protected person”) who reports to proper authorities an unlawful act or serious misconduct violating clear public policy, or who refuses to carry out an illegal directive. “Protected person” excludes certain managers whose job specifically includes safety or compliance oversight. The law allows a private lawsuit for actual and double (liquidated) damages, but not punitive damages.
2. Safety disclosures in healthcare facilities (RSMo § 197.285) Hospitals, ambulatory surgical centers, and abortion facilities must have written policies protecting employees who report (in good faith) violations relating to patient care or facility safety. The law bars retaliation, provides for confidential and anonymous disclosures, designates a compliance officer, and requires timely investigation and direct feedback to the reporting employee.
3. Nursing home district employee and resident reports (RSMo § 198.301) Missouri law prohibits retaliatory action—including dismissal, harassment, or eviction—against employees or residents of nursing home districts who make good-faith reports about legal or regulatory violations relating to safety or care.
Summary Missouri law does prohibit workplace retaliation for safety-related whistleblowing in a range of contexts, relying on both a general statute (with broad reach into private sector safety and legality reporting) and sector-specific protections for health care and nursing home environments. Federal OSHA’s whistleblower protections remain available for most private sector workers as the baseline.
