OSHA Laws in Maryland (2026): Your Rights, Their Rules
Most workers have no idea how strong Maryland’s workplace safety laws really are. Seriously. Maryland doesn’t just follow federal OSHA rules. It has its own system. And that system comes with real teeth.
Whether you’re an employee or an employer, this guide breaks it all down. Simply. Clearly. No legal jargon.
What Is MOSH?
Here’s where things get interesting. Maryland doesn’t use federal OSHA directly. Instead, it runs its own program called MOSH. That stands for Maryland Occupational Safety and Health.
MOSH is Maryland’s version of OSHA. Think of it like OSHA, but tailored specifically for Maryland workers. It’s one of 28 state-run safety programs approved by the federal government.
Wondering why this matters? Because MOSH has the power to make rules that go beyond what federal OSHA requires. And in recent years, it has done exactly that.
Who Does MOSH Cover?
Pretty much everyone who works in Maryland. MOSH covers all private-sector workplaces in the state. It also covers state and local government employees. That’s a wide net.
So simple! But there are a few exceptions. MOSH does not cover federal government employees. It also does not cover maritime workers like those in shipyards or on marine terminals. Those workers fall under federal rules instead.
Not sure if your job is covered? Most are. If you work for a Maryland business or a state or local agency, MOSH almost certainly applies to you.
Basic Employer Responsibilities
Okay, this part is important. Maryland law requires every employer to keep the workplace free from known dangers. That’s the foundation of everything MOSH does.
But it doesn’t stop there. Employers have several specific duties under MOSH rules.
Posting and Records
You have the right to know your rights. Employers must post the official MOSH poster in a visible spot at the workplace. This poster explains what workers are entitled to under the law.
Employers must also keep records of work-related injuries and illnesses. There’s a specific form for this: OSHA Form 300. Workers and former workers can access this log. Employers must post a summary of it every year from February 1 through April 30.
Small businesses with 10 or fewer employees get a partial break here. They are not fully required to keep these records in certain low-risk industries.
Reporting Serious Incidents
Hold on. This part is critical.
If something really bad happens at work, employers must report it fast. A worker death must be reported to MOSH within 8 hours. An in-patient hospitalization, amputation, or loss of an eye must be reported within 24 hours.
You can call MOSH during business hours at 410-527-4499. After hours, call 1-888-257-6674. Don’t wait. Missing this deadline is itself a violation.
Maryland-Specific Rules
This is where Maryland goes beyond what federal OSHA requires. And honestly, some of these rules are pretty important.
No Smoking Indoors
Maryland law bans smoking in all indoor workplaces. This isn’t just a health guideline. It’s a MOSH requirement. Employers must enforce it.
Heat Illness Prevention
Here’s a big one. Maryland finalized a new Heat Illness Prevention Standard on September 30, 2024. This is unique to Maryland. Federal OSHA still doesn’t have a final version of this rule.
Under this standard, if workers are exposed to a heat index of 80°F or more for at least 15 minutes in an hour, the employer must act. At 90°F or above, stricter rules kick in. These are called high-heat procedures.
What does the employer have to do? They must provide cool drinking water throughout the day. We’re talking at least 32 ounces per hour per worker. They must provide shade or other cooling options. They must help new workers and those returning from time off to adjust to the heat slowly. That process is called acclimatization.
Makes sense, right? Heat is genuinely dangerous. Maryland decided not to wait for the federal government to act.
Confined Spaces and Suspended Platforms
Maryland also has specific rules around confined spaces. These are areas like tanks, silos, or crawlspaces that workers may need to enter. Special safety measures apply before anyone goes in.
There are also rules for personnel platforms suspended from cranes or hoists. If you work in construction or heavy industry, these rules likely apply to your site.
Penalties and Consequences
Now here’s where things get serious. MOSH can issue citations and fines when it finds violations. The amounts depend on how serious the problem is.
A serious violation can cost an employer up to $7,000 per violation. That means each unsafe condition found during an inspection can result in its own fine. A non-serious violation can also result in a fine of up to $7,000, though this is technically optional for inspectors.
Think of it like a series of traffic tickets. Each one adds up fast.
If an employer doesn’t fix a violation by the deadline, additional daily fines of up to $7,000 can kick in. Every day the problem goes unfixed is another fine.
The worst cases are wilful or repeat violations. These can result in fines of up to $70,000 per violation. That’s not a typo. Seventy thousand dollars. Per violation.
Criminal penalties are also on the table. If a willful violation leads to a worker’s death, the employer can face up to $10,000 in fines. They can also face up to 6 months in prison. Or both.
Less severe than a felony in some ways, but still absolutely no joke.
What Happens After a Citation
When MOSH issues a citation, the employer must post a copy of it near the place of the violation. It stays up for three working days or until the problem is fixed, whichever takes longer.
If the employer disagrees, they have 15 working days to file a formal contest in writing. After that window closes, the citation stands.
Recent Law Changes in 2025 and 2026
Maryland has been busy updating its workplace safety laws. Here’s what’s new.
Davis Martinez Public Employee Safety and Health Act
This law took effect on October 1, 2025. It strengthens safety protections for public-sector workers. That includes government employees at the state and local level.
The law also expands recordkeeping requirements for public employers. As of March 2026, Maryland is proposing rules that would require all public bodies to report workplace injuries and illnesses. This would apply regardless of employer size or industry type. A public hearing on this proposal was held on March 17, 2026.
Electronic Injury Reporting
Starting in January 2026, covered employers must submit their 2025 injury and illness data through OSHA’s online Injury Tracking Application. This applies to workplaces with 250 or more employees. It also applies to smaller businesses in high-hazard industries if they have 20 to 249 workers.
Accuracy matters here. OSHA uses this data to spot patterns and target inspections.
Your Rights as a Worker
You’re not alone in this. MOSH gives workers real power to protect themselves.
You have the right to report unsafe conditions. You can do it anonymously. MOSH will investigate without revealing your name. To file a complaint during business hours, call 410-527-4499. After hours, call 1-888-257-6674.
You also have the right to refuse work that poses an imminent danger. This means a threat of death or serious injury. You can’t be fired or punished for reporting safety problems. That type of punishment is called retaliation. MOSH investigates retaliation claims too.
Most people don’t realize how many rights they actually have. Now you do.
Free Help for Employers
Here’s something a lot of small business owners don’t know about. MOSH offers a free consultation service. It’s confidential. No fines. No penalties.
This service is designed for small businesses. If your company has fewer than 250 employees on-site or fewer than 500 nationwide, you can request a free visit. MOSH consultants will come to your workplace. They’ll help you find hazards and fix them before an official inspection ever happens.
Participating in the consultation program can even earn your business a one-year exemption from routine MOSH inspections. That’s a solid deal.
To request a consultation, contact MOSH at 410-527-4472 or email [email protected].
How to Report a Workplace Safety Problem
Trust me, this is easier than most people think.
If you see a safety hazard at work, you can report it to MOSH. You don’t have to give your name. Just call and describe the problem.
During business hours: 410-527-4499. After hours or for emergencies: 1-888-257-6674. You can also contact MOSH by mail at 10946 Golden West Drive, Suite 160, Hunt Valley, MD 21031.
MOSH will decide whether to conduct an inspection. Inspections can happen because of complaints, serious incidents, scheduled reviews, or referrals from other agencies.
If there’s an imminent danger at your workplace, don’t wait. Call the after-hours line immediately.
Frequently Asked Questions
Does MOSH apply to my small business? Yes, if you have at least one employee in Maryland and operate in the private sector or as a state or local government, MOSH covers you.
