State-Plan jurisdiction: coverage of political subdivisions, public universities, and contractors
Illinois operates an OSHA-approved state plan covering only state and local government employers—federal OSHA retains full authority for the private sector. Under Illinois law, a “public employer” (for IL OSHA purposes) means the State of Illinois or any political subdivision, which explicitly includes counties, municipalities, townships, school districts, public universities, commissions, and municipal corporations. The Illinois Occupational Safety and Health Act (820 ILCS 219) and the Illinois Administrative Code (56 Ill. Adm. Code Part 350) set the boundaries: all direct employees of these entities are public employees for state-plan purposes.
Political subdivisions: All employees of any political subdivision are covered. This includes employees of counties, cities, school districts, and other municipal corporations. There is no carve-out for type or function—as long as the entity is a political subdivision established by state law, its employees are covered by IL OSHA. (820 ILCS 219/5, 15)
Public universities and public-private partnerships: Employees of state universities and colleges are specifically included because these institutions are arms of the State. Employment status for persons working in public-private partnerships (PPPs) is governed by whether the worker is an employee of the public (state or political subdivision) entity. If they are hired directly by the public entity, state plan coverage applies. If they are employed by a private partner, they are subject to federal OSHA. The dividing line is the employment relationship.
State contractors: Illinois OSHA does not automatically cover private contractors. IL OSHA only extends to individuals who are "in the service of" a public employer (by election, appointment, or contract). If the contract places the individual into a direct employment relationship (for example, a contractor who is functionally working as a public employee), they may be treated as covered public employees. Standard vendors, independent contractors, and their employees are not covered, unless their contract with the public entity explicitly creates an employment relationship within the definition of "public employee" in 820 ILCS 219/5. There is no regulatory carve-out for PPPs or university staff—coverage turns on who is the employer of record under state law.
In short:
- IL OSHA covers direct employees of the State, political subdivisions, and public universities.
- Coverage of public-private partnerships and contractors turns on whether the individual is an employee of a public entity.
- There is no carve-out for PPPs or public university staff, but private-sector staff in these contexts are covered by federal OSHA.

Severe injury and fatality reporting — public employers
State and local government employers in Illinois must report work-related fatalities to Illinois OSHA within eight hours. Employers must also report any work-related inpatient hospitalization, amputation, or loss of an eye within twenty-four hours. Reports must be made by calling IL OSHA's 24/7 number at 217-782-7860. The reporter must provide the establishment name, incident location and time, number of fatalities or hospitalized employees, names of injured employees, and a contact person with phone number.

Recordkeeping requirements for state and local government employers under IL OSHA
Illinois state and local government employers covered by IL OSHA must maintain records of occupational injuries and illnesses, as established by statute, regulation, and agency guidance.
Statutory and Regulatory Authority: Under the Illinois Occupational Safety and Health Act (820 ILCS 219/55), the Director of Labor is authorized to require public employers to keep records on work-related injuries and illnesses, and to promulgate rules specifying such requirements. The implementing regulation, 56 Ill. Adm. Code § 350.290, states that employers "shall keep such records as are required by the Director" and follow any additional recordkeeping or reporting procedures specified by the Director.
Agency Guidance—Forms and Procedures: The Illinois Department of Labor (IDOL), through IL OSHA, directs public-sector employers to use OSHA Forms 300 (Injury and Illness Log), 301 (Incident Report), and 300A (Annual Summary) or equivalent forms, mirroring the federal OSHA system. The guidance further specifies:
- Each recordable work-related injury or illness must be logged on Form 300 within seven days of receiving information about the case.
- Form 301 (or equivalent) must be completed for each recordable case.
- The Annual Summary (Form 300A) must be posted in the workplace from February 1 to April 30 each year, even if there were no recordable incidents.
- Records must be retained for five years following the calendar year that they cover.
These details—including retention period, specific forms, posting dates, and entry window—are set by IL OSHA guidance and are not explicitly enumerated in the statutory or regulatory text.
Partial Exemption: Certain low-hazard public sector establishments (as defined by the Director) may be exempt from some recordkeeping, but they must still comply with severe injury and fatality reporting. The full list of exemptions is maintained by the Department of Labor.
For the most current interpretive requirements and possible exemptions, refer to Illinois OSHA's official recordkeeping guidance page linked below, as these specifics may be updated by administrative action.

Applicable occupational safety and health standards for Illinois public employers under IL OSHA
Illinois OSHA (IL OSHA) enforces occupational safety and health standards for state and local government employers by adopting federal OSHA standards by reference, with limited Illinois-specific enhancements. This public employer state plan was initially approved by federal OSHA in 2009 (see 820 ILCS 219/15; 29 U.S.C. § 667(c)), requiring Illinois to maintain standards at least as effective as federal OSHA rules.
Covered Standards: IL OSHA adopts the federal occupational safety and health standards for general industry (29 C.F.R. § 1910), construction (29 C.F.R. § 1926), and maritime (29 C.F.R. §§ 1915, 1917, 1918) for public-sector workplaces, through 56 Ill. Adm. Code Part 350, unless otherwise amended by Illinois rulemaking. The adopted standards include requirements on hazard communication, lockout/tagout, bloodborne pathogens, confined space entry, personal protective equipment (PPE), machine guarding, and fall protection, among others.
Material Change Effective December 29, 2025: An amendment to 56 Ill. Adm. Code Part 350, effective December 29, 2025, clarifies that Illinois OSHA’s enhanced reporting requirements for certain public employers replace, rather than supplement, the similar federal OSHA reporting obligations. This applies to public employers with 100 or more employees in road maintenance, construction, local fire protection, water supply/distribution, or sewage treatment. These employers must now follow the Illinois reporting rules for severe injury, fatality, and illness reporting as specified in state regulations rather than duplicating federal requirements.
Illinois-Specific Standards: Apart from the enhanced reporting regulation above, as of January 2026, Illinois does not impose permanent occupational safety and health standards differing from those adopted from federal OSHA, but retains authority to promulgate stricter or supplemental requirements through state rulemaking (56 Ill. Adm. Code § 350.110 and subsequent amendments).

Illinois OSHA penalty schedule for public employers — inflation adjustment, trend, and federal comparison
The Illinois Occupational Safety and Health Act (IL OSHA) establishes a schedule of civil penalties for violations by state and local government (public) employers, set out in 820 ILCS 219/85. These statutory penalty amounts are fixed dollar figures: up to $10,000 per willful or repeat violation (with a minimum $1,000 per willful violation), and up to $1,000 for serious, other-than-serious, posting, or failure-to-abate violations. As of January 2026, these maximums have remained unchanged since the Act's major re-adoption effective January 1, 2015, and are not indexed to inflation.
No automatic inflation adjustment: Unlike federal OSHA (which annually adjusts private-sector maximum penalties for inflation under the Federal Civil Penalties Inflation Adjustment Act), Illinois public-employer penalties are fixed by statute. There is no language in 820 ILCS 219/85 authorizing or requiring the Department of Labor to update or increase maximum penalties in response to inflation or cost-of-living changes. The penalty schedule is only modified if the Illinois General Assembly amends the statute. As a result, Illinois penalties for public employers remain substantially lower than the current federal OSHA caps for the private sector (in 2026, over $16,000 per serious violation and $161,000 per willful violation under 29 U.S.C. § 666).
No confirmed active legislative proposals: As of July 6, 2026, there is no pending bill, adopted regulation, or Department of Labor rulemaking proposing to raise these statutory caps or tie them to inflation. Active legislation can be checked on the Illinois General Assembly website, but no bills meeting that description are currently moving forward. Administrators and practitioners should be aware that while the General Assembly could act to increase penalties at any time, there is no evidence of such action or imminent change based on official sources.

Employee complaint rights and anti-retaliation protections for Illinois public employees under IL OSHA
Illinois public employees (state and local government workers) have the right to report unsafe or unhealthy working conditions to the Illinois Department of Labor’s Division of Occupational Safety and Health (IL OSHA) under the Illinois Occupational Safety and Health Act. Employees or their representatives may file safety or health complaints directly with IL OSHA, and the agency must keep the identity of any complainant confidential if requested (820 ILCS 219/60(d)). Upon receiving a complaint, IL OSHA may conduct inspections to determine compliance with occupational safety and health standards.
Anti-retaliation protections: Section 65 of the Act (820 ILCS 219/65) strictly prohibits public employers from retaliating against employees for exercising their rights under the Act. This includes filing a complaint, instituting or testifying in any proceeding, or reporting an injury, illness, or exposure. The statute states that "no public employer shall discharge, suspend, demote, transfer, or otherwise discriminate against any public employee" for these protected activities.
Filing retaliation complaints and remedies: A public employee who believes they have suffered retaliation must file a complaint with the Illinois Department of Labor within 30 days of the alleged violation. If the Department finds a violation, it may order remedies including reinstatement and payment of back wages. The law specifically authorizes “reinstatement of the employee to the employee's former position and payment of the employee's back wages,” as well as other “appropriate relief” deemed necessary to make the employee whole.
These rights and protections apply only to the public sector in Illinois. Private-sector employees in Illinois are covered by federal OSHA standards and procedures instead.
