OSHA Inspections in Delaware Commercial Cleaning (2026)

Who enforces OSHA in Delaware commercial cleaning

Delaware is a federal OSHA state — there is no Delaware state plan for private-sector workers. All private-sector commercial cleaning contractors are covered by federal OSHA under OSHA Region III (Philadelphia). The sole Delaware enforcement office is the Wilmington Area Office located at 800 N. King Street, Suite 302, Wilmington, DE 19801-3549; (302) 573-6518. Delaware's entire commercial geography (Wilmington financial district, Dover government center, Dover Air Force Base vicinity, and Sussex County agricultural-industrial corridor) is served by this one area office. Federal OSHA covers all private-sector employers; Delaware state and local government workers do not have a separate state-plan protection and are covered by federal OSHA through a special program.

Top-cited standards (janitorial NAICS 561720)

• 29 CFR 1910.147 — Lockout/Tagout: Required when cleaning or servicing powered equipment. Delaware's pharmaceutical manufacturing and chemical facilities (DuPont legacy sites, AstraZeneca) are major clients for industrial cleaning contractors — LOTO compliance is especially critical at these locations.
• 29 CFR 1910.1030 — Bloodborne Pathogens: Delaware has ChristianaCare (a major regional healthcare system headquartered in Wilmington), Bayhealth Medical Center, and multiple urgent-care chains. Janitorial contractors at these facilities require written ECPs and annual BBP training with documented HBV vaccine offers.
• 29 CFR 1910.1200 — Hazard Communication: Applies to all cleaning products. Delaware's dense commercial-office and financial-sector clients (bank headquarters in Wilmington) require routine chemical use (carpet cleaners, floor strippers, disinfectants) with full SDS compliance.
• 29 CFR 1910.28 — Fall Protection: Required for cleaning work at heights in Delaware's mid-rise office towers in the Wilmington CBD and elevated areas in industrial facilities along the Christina River corridor.
• 29 CFR 1910.303 — Electrical (General): Cited for damaged power cords on floor machines, lack of GFCI protection in wet environments, and improper use of extension cords in Delaware's older commercial building stock.

What's specific to Delaware

• Delaware's corporate-charter state status means thousands of corporations are legally incorporated in Delaware but operate facilities nationwide — however, OSHA jurisdiction is determined by where workers physically perform work, not where the company is incorporated. A janitorial company incorporated in Delaware but cleaning in New Jersey is covered by New Jersey (federal OSHA covers private sector there too, or a state plan if applicable).
• Dover Air Force Base is a major federal installation — janitorial contractors on federal property may be subject to federal agency OSHA programs (29 CFR 1960) rather than regular OSHA area-office enforcement. Verify jurisdiction before starting work on any federal installation.
• Delaware has free OSHA consultation through the Delaware Department of Labor's Safety and Health Consultation Program — employers can request a free, confidential on-site evaluation without triggering enforcement.
• NAICS 561720 janitorial companies with 11+ employees in Delaware must maintain 29 CFR 1904 OSHA 300 injury logs. Delaware's small average establishment size in janitorial (many firms under 10 employees) means many companies qualify for the partial exemption, but must document the prior-year employee count to substantiate it.

2026 penalty structure

Federal OSHA FY2026 penalty schedule (effective January 15, 2025): Serious violations — up to $16,550 per violation; Willful or Repeat — up to $165,514 per violation; Failure to Abate — $16,550 per day. Small-employer reductions available (up to 60% for ≤25 employees) on serious violations; no discretionary reduction available for willful violations below $11,823 minimum.

Practical first steps

• If your company cleans pharmaceutical or chemical manufacturing sites in the Wilmington area, develop site-specific Lockout/Tagout procedures for each client location and conduct documented LOTO training before deploying any worker to those facilities.
• Confirm BBP Exposure Control Plans are current for all healthcare and laboratory cleaning contracts — OSHA requires annual review of the ECP (29 CFR 1910.1030(c)(1)(iv)) and documentation of HBV vaccine declinations for all workers who decline the vaccine.
• For any cleaning work on federal property in Delaware, contact the Wilmington Area Office to confirm whether the work falls under the federal agency OSHA program (29 CFR 1960) or is covered by standard OSHA enforcement.
• Request a free consultation through the Delaware Department of Labor's Safety and Health Consultation Program to audit your chemical inventory and SDS files before any OSHA programmed inspection.
