Right to Know Law: Your Employees' Chemical Safety Rights

What Is the Right to Know Law?

The Right to Know law grants every worker in the United States the legal right to access information about hazardous chemicals in their workplace. Rooted in OSHA's Hazard Communication Standard (29 CFR 1910.1200), this law requires employers to identify chemical hazards, maintain Safety Data Sheets, label containers, and train employees on safe handling practices.

Before this regulation existed, workers handled dangerous substances daily with zero information about what they were breathing, touching, or risking exposure to. Fatal chemical accidents in the 1970s and early 1980s pushed federal and state governments to act. The result was a framework that shifted power back to workers — giving them the ability to know exactly what chemicals surround them and how to protect themselves.

It's one of those laws that seems obvious in hindsight. Of course workers should know what chemicals they're handling. But it took deaths and permanent injuries before anyone wrote it down.

Federal vs. State Right to Know Laws

There's a common misconception that one single federal law covers everything. The reality is more layered.

OSHA's HazCom Standard serves as the federal baseline. Every employer with hazardous chemicals must comply regardless of location. But many states enacted their own Right to Know laws — some predating the federal version — with requirements that go further.

Aspect	Federal (OSHA HazCom)	State Right to Know Laws
Scope	Private sector employers	Often includes public sector, community members
Chemical lists	Based on GHS classification	Some states maintain separate chemical lists
Reporting	SDS availability on request	May require proactive reporting to fire departments or agencies
Penalties	Up to $16,550 per serious violation	Varies — some states impose additional fines
Community access	Limited	Many states grant public access to chemical inventories

New Jersey's Worker and Community Right to Know Act, for example, requires employers to submit environmental surveys and label all containers with specific chemical names — not just generic hazard categories. California, Pennsylvania, and New York have similarly robust state-level requirements.

The bottom line: always check your state's specific requirements on top of federal compliance. Meeting OSHA minimums alone won't necessarily keep you out of trouble.

What Employers Must Provide Under Right to Know

Compliance breaks down into four core obligations. Skip any one of them and you're exposed to citations.

1. Maintain a written Hazard Communication Program — a document outlining how your company handles chemical hazards, including labeling procedures, SDS management, and training schedules
2. Keep Safety Data Sheets accessible — every hazardous chemical on-site needs a current SDS that workers can access during their shift without asking permission or waiting
3. Label all chemical containers — original manufacturer labels must stay intact; secondary containers need proper labeling with product identifier, hazard warnings, and pictograms
4. Train employees before exposure — workers must receive training on chemical hazards present in their work area, how to read SDSs and labels, and what protective measures to use

That second point trips up a lot of small businesses. "Accessible" means during every shift, immediately available. A binder locked in the manager's office doesn't count. Neither does telling employees to "just Google it." You need a reliable system — whether that's a physical SDS binder at each work station or a digital solution like MySDS Manager that gives your team instant access from any device.

Employee Rights Under the Law

Workers aren't passive recipients here. The law gives them specific, enforceable rights. They can request and receive SDSs for any chemical they work with or near. They're entitled to training in a language and vocabulary they understand. They can file complaints with OSHA if an employer refuses to provide chemical information. Under certain conditions, they can refuse to work with a chemical if the employer hasn't provided required information. And they have access to their own exposure and medical records.

An employee who asks for an SDS and gets pushback has every right to call OSHA. And those complaints trigger inspections that rarely end with just one finding. I've seen a single employee complaint snowball into five-figure fines because the inspector found a dozen other issues while they were there.

How Right to Know Connects to the HazCom Standard

Think of the HazCom Standard as the operational framework that makes the Right to Know principle enforceable. The "right" is the concept; HazCom is the mechanism.

When OSHA revised HazCom in 2012 to align with the Globally Harmonized System (GHS), it standardized how chemical hazards get communicated worldwide. The 2024 update refined things further — particularly around GHS label requirements and SDS formatting.

For small businesses, the practical impact is straightforward: follow HazCom requirements and you satisfy the Right to Know law. But you need to actually follow them — not just have a dusty binder from 2015 sitting on a shelf somewhere.

Common Right to Know Violations

OSHA's most-cited violations consistently include HazCom failures. Here's what inspectors flag most often:

Violation	Why It Happens	Typical Penalty
No written HazCom program	Owner didn't know it was required	$4,000-$16,550
Missing or outdated SDSs	New products added without updating records	$4,000-$16,550
No employee training	Training skipped for new hires or when new chemicals arrive	$4,000-$16,550
Unlabeled secondary containers	Workers transfer chemicals without labeling	$4,000-$16,550
SDSs not accessible during shifts	Binder locked away or system offline	$4,000-$16,550

Each violation is per instance. Five unlabeled containers means five separate citations. The math gets painful fast — especially when OSHA penalty amounts keep increasing annually.

How Small Businesses Can Stay Compliant

You don't need a full-time safety officer or a six-figure compliance budget. Most small businesses can handle Right to Know requirements with a systematic approach:

1. Audit your chemical inventory — walk through every area and list every chemical product, from industrial solvents to cleaning supplies
2. Collect current SDSs — contact manufacturers or use reliable SDS databases to get up-to-date sheets for every product
3. Write your HazCom program — it doesn't need to be 50 pages; a clear, practical document covering your specific workplace works fine
4. Set up accessible SDS storage — a digital SDS management system like MySDS Manager eliminates the hassle of maintaining physical binders across locations
5. Train your team — cover chemical hazards, how to read an SDS, label comprehension, and emergency procedures
6. Document everything — keep training records, chemical inventory logs, and SDS access logs as proof of compliance

Frequently Asked Questions

Does the Right to Know law apply to every employer?

Any employer with hazardous chemicals in the workplace must comply with OSHA's HazCom Standard. This includes common products like cleaning supplies, paints, and adhesives. Exemptions exist for consumer products used in the same manner and duration as normal consumer use, but most workplace applications don't qualify for that exemption.

Can an employer refuse to show an employee a Safety Data Sheet?

No. Under federal law, employers must provide SDS access during each work shift. Refusing is a direct violation of the HazCom Standard and can result in OSHA citations. Employees can file a confidential complaint with OSHA if access is denied.

What's the difference between Right to Know and EPCRA?

The Right to Know law (via OSHA HazCom) focuses on worker safety — ensuring employees know about workplace chemical hazards. EPCRA (Emergency Planning and Community Right-to-Know Act) extends chemical reporting requirements to communities and emergency responders. Businesses storing chemicals above threshold quantities must report to local emergency planning committees under EPCRA, which is separate from OSHA requirements.
