Maryland operates its own OSHA-approved State Plan, which sets and enforces occupational safety and health regulations throughout the state. This plan is administered by the Maryland Occupational Safety and Health (MOSH) division, which is part of the Maryland Division of Labor and Industry (DLI). MOSH is responsible for protecting both public and private sector employees by conducting inspections, enforcing standards, and providing compliance assistance within the state.
Maryland operates an OSHA-approved State Plan, known as the Maryland Occupational Safety and Health (MOSH) program, administered by the Maryland Division of Labor and Industry (DLI). This State Plan applies to all public sector employees and most private sector workers in Maryland, with a few specific exceptions.
Federal OSHA retains jurisdiction over the following areas and personnel:
All working conditions of onboard cabin crew members
Marine employment, including shipyard and longshoring operations
All employment on federal military bases
U.S. Postal Service employees and contractors working in USPS-operated facilities
Any operations, employers, or employees not specifically covered by the Maryland State Plan
Additionally, Federal OSHA maintains exclusive authority over certain provisions, such as the anti-retaliation provision of the Occupational Safety and Health Act of 1970 (Section 11(c), 29 USC 660(c)). However, MOSH is authorized to conduct investigations into alleged incidents of workplace retaliation when appropriate.
Although most State Plans adopt the core of Federal OSHA Standards, MOSH has implemented unique requirements tailored to address state-specific workplace risks. Some of these Maryland-specific standards include:
Fall protection during steel erection
Lead safety protocols
Protective systems for excavation work
Crane safety regulations
Prohibition of smoking in indoor workplaces
Confined space entry standards
Regulations for personnel platforms suspended from cranes, derricks, or hoists
Formaldehyde exposure limits
Tree care and removal industry standards
Field sanitation requirements
MOSH is responsible for enforcement activities including inspections, citations, penalties, and recordkeeping requirements. The agency also handles worker complaints and referrals. While OSHA does not mandate training under federal law, both Federal OSHA and MOSH strongly recommend workers undergo appropriate safety training—such as the OSHA 10-Hour or 30-Hour programs—based on their roles and exposure risks.
