OSHA Inspections in Massachusetts Commercial Cleaning (2026)

Jurisdiction overview: federal OSHA and Massachusetts DLS split enforcement

Massachusetts has a partial state plan covering only state and local government workers. Private-sector janitorial contractors are covered by federal OSHA Region 1 (Boston) through three area offices: Boston North (Andover), Boston South (Braintree), and Springfield. The Massachusetts DLS Workplace Safety and Health Program (72 School Street, Taunton, MA 02780; (508) 616-0461) enforces MGL c.149, §§6 and 6-1/2 for public employers, typically issuing a Written Warning before a Civil Citation — and offering a free Voluntary Assistance program. At a municipal building, federal OSHA covers the contractor's employees while DLS covers the city's workers.

Inspection priorities for NAICS 561720 janitorial services

• 29 CFR 1910.1030 — Bloodborne Pathogens: Massachusetts has an extraordinarily dense healthcare sector (Mass General Brigham, Dana-Farber, Beth Israel Deaconess, Tufts Medical Center, UMass Memorial, Boston Children's Hospital, and hundreds of academic medical affiliates). Janitorial contractors at any healthcare, biotech, research lab, or clinical facility must maintain a current written Exposure Control Plan, document HBV vaccine offers within 10 working days of assignment, and provide annual BBP training with employee-signed acknowledgments.
• 29 CFR 1910.1200 — Hazard Communication GHS: Written HazCom program, SDS binder, GHS-labeled secondary containers, documented annual training. For private-sector cleaning companies, federal HazCom (29 CFR 1910.1200) applies. For contracts at public-sector facilities, the client's workers are covered by MGL c.111F (Massachusetts Right-to-Know), which requires employees to receive written chemical information within four working days of request — contractors must be prepared to provide SDS files on demand.
• 29 CFR 1910.147 — Lockout/Tagout: The #1 penalty-generating citation for NAICS 561720 nationally. Massachusetts's large biotech and pharmaceutical manufacturing sector (Biogen, Moderna, Pfizer Andover, AstraZeneca Waltham) plus its healthcare campuses means janitorial contractors routinely encounter complex energy-isolation requirements. Machine-specific LOTO procedures and annual training documentation are mandatory.
• 29 CFR 1910.28 — Fall Protection: Required for elevated cleaning in Boston's extensive high-rise commercial stock, Fenway Park and TD Garden cleaning crews, and Route 128 technology-campus elevated mechanical rooms.
• 29 CFR 1910.134 — Respiratory Protection: Spray disinfectants, floor-stripping chemicals, and cleaning in biotech/pharmaceutical environments may require respiratory protection. Medical evaluation and fit-test required before any tight-fitting respirator use. OSHA's Boston Region has enforced respiratory protection at laboratory-cleaning operations.

Recent enforcement actions

OSHA's Boston Region covers Massachusetts, Connecticut, Rhode Island, Vermont, New Hampshire, and Maine. Recent enforcement relevant to Massachusetts janitorial contractors: In October 2024, OSHA's Boston Region cited a Massachusetts waterproofing contractor after a fatal crushing death in Hanson — illustrating the Boston Region's fatality-investigation enforcement posture. In July 2024, Boston Region cited a contractor for repeated trench violations in Massachusetts and Rhode Island. For NAICS 561720 specifically, OSHA's Boston Region has issued BBP and HazCom citations to cleaning companies at healthcare campuses in the Route 128 corridor. Search the OSHA Establishment Search for prior inspection records at Massachusetts worksites. DLS citation records for public-sector inspections are available through the DLS WSHP portal at mass.gov/dols/wshp.

Penalty schedule — federal OSHA and DLS

Private-sector (federal OSHA): Serious — up to $16,550; Willful/Repeat — up to $165,514; Failure to Abate — $16,550/day (effective January 15, 2025). Public-sector (DLS): Written Warning → Order to Correct → Civil Citation under MGL c.149, §§6, 6-1/2. MGL c.111F violations carry civil penalties enforced by DLS.

Required programs and recordkeeping

• Written Bloodborne Pathogen Exposure Control Plan — 29 CFR 1910.1030(c): Annual review; exposure determination listing all job classifications; HBV vaccine offer and documentation within 10 working days of assignment to exposed tasks; sharps injury log under 29 CFR 1904.35.
• Written Hazard Communication Program — 29 CFR 1910.1200(e): For private-sector employers. For public-sector cleaning contracts, additionally comply with MGL c.111F requirements: respond to employee SDS requests within four working days; maintain SDS files for 30 years from last product use; post Massachusetts Right-to-Know Notice at the workplace.
• OSHA 300/300A/301 Recordkeeping — 29 CFR 1904: NAICS 561720 is not exempt. Janitorial contractors with 11+ employees must maintain logs; 300A posted February 1 – April 30. DLS public-sector employers must separately submit injury data to DLS per DLS WSHP requirements.

State-specific rules — Massachusetts Right-to-Know (MGL c.111F)

• Massachusetts Right-to-Know Law (MGL c.111F / 454 CMR 21.00): Applies to public-sector employers. Key requirements: SDS files available to employees within four working days of written request; post a Right-to-Know Workplace Notice in English (and employees' primary language); annual training; containers over 5 lbs or 1 gallon labeled; SDS files retained for 30 years from last product use. Contractors cleaning public buildings must have a documented procedure for responding to SDS requests on behalf of the facility's public-employer workforce.
• Private-sector: Federal 29 CFR 1910.1200 (HazCom) applies — not MGL c.111F. Contractors serving both private and public facilities must maintain two parallel chemical-disclosure systems.

How janitorial contractors prepare for OSHA compliance in Massachusetts

• For healthcare and biotech cleaning contracts along Route 128, develop facility-specific LOTO procedures (29 CFR 1910.147) for every piece of powered equipment encountered — OSHA's Boston Region enforces LOTO vigorously in pharmaceutical and research-lab environments where cleaning crews access mechanical rooms and process areas.
• If your company cleans public buildings (schools, courthouses, municipal offices), establish a MGL c.111F-compliant procedure to respond to employee SDS requests within four working days and retain SDS files for 30 years — even if the product has been discontinued.
• Conduct annual BBP training with dated sign-in sheets and document HBV vaccine offers for every worker assigned to healthcare, dental, or research-lab cleaning — OSHA's Boston Region has issued BBP citations at Massachusetts academic medical center cleaning operations.
• Request free DLS Voluntary Assistance ((508) 616-0461) for any public-sector building contract to ensure compliance with MGL c.149 §§6/6-1/2 requirements — DLS will not issue warnings or penalties under the Voluntary Assistance program.
