How to Comply With Hazardous Communication Standards?
Hazardous chemicals are present in nearly every workplace. Complying with hazardous communication standards protects your employees and keeps your business on the right side of regulations from the Occupational Safety and Health Administration (OSHA).
The challenge is knowing exactly which steps to take when OSHA’s regulatory language runs hundreds of pages deep. This guide breaks down how to comply with hazard communication (HazCom) standards with five straightforward steps.

What Is the OSHA Hazard Communication Standard (HCS)?
The Hazard Communication Standard (HCS) ensures that everyone in a workplace understands the chemical hazards they may encounter. It requires chemical manufacturers, importers and employers to classify hazards and communicate that information through labels and safety data sheets.
You might hear people call it the “Right-to-Know” law, but OSHA has evolved the concept to “Right-to-Understand” because knowing a hazard exists means little if you can’t act on that knowledge. The HCS aligns with the Globally Harmonized System (GHS), which creates a common approach to classifying chemicals and communicating hazard information worldwide.
The 5 Core Steps to OSHA HazCom Compliance
Building a compliant HazCom program comes down to five essential steps that work together to protect your employees and demonstrate regulatory compliance.
1. Create and Maintain a Written Hazard Communication Program
OSHA requires this document under Title 29 of the Code of Federal Regulations, Section 1910.1200(e), and it must include:
- Labeling policy: Describe how your company meets labeling requirements for containers in the workplace.
- Safety data sheet (SDS) management: Explain how you obtain and maintain SDSs and where employees can access them.
- Training program outline: Detail when and how employees receive hazard communication training.
- Chemical inventory: Maintain a comprehensive list of all known hazardous chemicals present at your facility.
This document consolidates all your compliance efforts into a single system.
2. Properly Label Containers and Manage Warnings
Container labeling gives employees immediate hazard information at the point of use. Labels on shipped containers from manufacturers must remain intact and legible. All shipped containers in your workplace need labels that include six key elements aligned with GHS requirements:
- Product identifier
- Signal word
- Hazard statement
- Precautionary statement
- Pictograms
- Supplier information, including, at a minimum, their name, address and phone number
Understanding workplace container labeling requirements helps you maintain compliance as chemicals move through your facility. The standardized label format means employees can quickly identify hazards and take appropriate precautions.
3. Keep and Manage Your SDSs
Every hazardous chemical in your workplace requires an accessible SDS. Employers must ensure SDSs are available to employees during their work shifts when they need to reference hazard information.
The 16-section SDS format provides comprehensive details about each chemical:
- Sections 1-8: These sections cover general information regarding chemical identification, hazards, composition, safe handling practices, exposure controls and emergency control measures like fire-fighting procedures. They provide quick-access information for immediate response situations.
- Sections 9-11 and 16: Technical and scientific information covering physical and chemical properties, stability and reactivity data, toxicological information and preparation dates. These sections support deeper understanding and long-term safety planning.
The information must appear in English, though additional languages can supplement the English version. When no applicable information exists for a required element, the SDS must state that clearly rather than leaving the section blank.
If you maintain SDSs electronically, you need a reliable backup system ready to go during power outages, equipment failures or other emergencies that could knock out your primary system. Train your employees on how to use the electronic system to access SDSs and make sure they can obtain hard copies when needed.
4. Conduct Effective Employee Training
Employers must train workers on the specific hazards they face and the protective measures they should take. Effective, OSHA-compliant employee training covers your written program, how to read labels and SDSs, the details of workplace hazards and where and how to obtain additional information.
Training for hazard communication is required when employees first work with hazardous chemicals and again when new hazards are introduced. Many employers also conduct annual refresher training. This ongoing education fosters a culture in which everyone understands how to work safely with chemicals.
⚠️ New Deadline Extension: On January 15, 2026, OSHA officially issued an extension on the compliance dates for the 2024 HCS updates. Because the agency needed more time to finalize its guidance materials, the initial deadline for chemical manufacturers, importers, and distributors to evaluate and update substances was extended from January 19, 2026, to May 19, 2026. All subsequent employer and mixture transition deadlines have also been pushed back by four months.
5. Periodically Evaluate and Reassess Your Program
Review and update your program when new hazards enter the workplace or when the program shows signs of losing effectiveness. The recent updates to the HCS that aligned with GHS Revision 7 demonstrate why periodic evaluation matters. The final rule became effective in 2024, introducing changes that compliant programs needed to incorporate. Regular program assessment helps you catch gaps before they become violations.
HazCom Violations and Penalties
Hazard communication consistently appears among OSHA’s most frequently cited standards, typically ranking second on the annual list. This rank shows that many employers struggle with the requirements and that OSHA actively enforces them during workplace inspections.
The financial risk of violations is substantial. OSHA penalties can exceed $16,000 per violation, and serious violations often appear in multiples when inspectors find systemic program failures. These penalties represent avoidable costs that proper compliance prevents.
Frequently Asked Questions About HazCom
These common questions help clarify specific aspects of hazard communication compliance.
What Is the Difference Between a Safety Data Sheet (SDS) and a Material Safety Data Sheet (MSDS)?
The terms describe the same type of document at different points in regulatory history. MSDS was the older term used before OSHA aligned the HCS with GHS. The current term is SDS, and the format now follows the standardized 16-section GHS format.
