Workplace chemical safety
Hazard Communication Compliance Checklist: Avoid OSHA Citations
Hazard Communication—commonly called HazCom—applies wherever employees may be exposed to hazardous chemicals at work. A compliant program is more than a folder of Safety Data Sheets: employers must connect their chemical inventory, labels, SDS access, written procedures, and employee training into a system workers can use every day.
Important: this guide is a practical compliance reference, not legal advice. State Plans, contract terms, chemical-specific standards, and the nature of a task may create additional obligations.
What OSHA expects from a HazCom program
OSHA’s Hazard Communication Standard, 29 CFR 1910.1200, requires employers to provide employees with information about hazardous chemicals in their work area. At its core, the standard requires a written hazard communication program, a list of hazardous chemicals, appropriate labels or other warnings, readily accessible Safety Data Sheets, and effective employee information and training.
This can apply well beyond manufacturing. Construction, warehousing, maintenance, hospitality, food service, healthcare, laboratories, retail operations, and cleaning teams may all use products that trigger HazCom duties—from solvents and adhesives to disinfectants, fuels, compressed gases, and cleaning chemicals.
Maintain a chemical inventory
Keep an accurate list of hazardous chemicals known to be present in each workplace. The product identifier should allow the inventory, container label, and SDS to be matched easily.
Protect labels and warnings
Do not remove or deface incoming labels. Ensure workplace and secondary-container labeling communicates the relevant hazards, unless the limited immediate-use exception applies.
Make SDSs readily accessible
Workers must be able to access the relevant SDS during every shift in their work area. Electronic systems can work, but employees need dependable access and a practical backup plan.
Use a written program
Document how the workplace will meet its label, SDS, and training duties, including how it will communicate hazards at multi-employer worksites and during non-routine tasks.
Train before exposure
Provide effective information and training at initial assignment and when workers may encounter a new chemical hazard they have not previously been trained to recognize.
Assign clear ownership
Make someone responsible for maintaining the inventory, collecting SDSs, reviewing workplace labels, and coordinating updates. Clear ownership is a sound way to prevent gaps.
What inspectors and workers will notice first
Common compliance gaps
- An inventory that does not match chemicals actually in use.
- Unlabeled or poorly labeled secondary containers.
- Missing SDSs, or SDSs employees cannot access promptly.
- A written program copied from a template but not adapted to the workplace.
- Workers unable to explain labels, pictograms, key SDS sections, or protective measures.
- Temporary workers or contractors not informed about workplace chemical hazards.
Questions your team should answer
- What hazardous chemicals are used in this work area?
- Where are the SDSs, and how can they be accessed during this shift?
- What do the label signal word, pictograms, and hazard statements mean?
- What controls, PPE, storage rules, and emergency actions apply?
- Who must be informed before contractors begin work nearby?
- What happens when a new product or chemical hazard is introduced?
HazCom training is necessary—but it is not the whole program
Training should help employees recognize chemical hazards, understand labels and SDSs, identify protective measures, and know how to respond to a release or exposure. It must be understandable to the workforce and relevant to the actual chemicals and tasks in the work area.
A general safety course can support baseline awareness, but it does not replace the employer’s responsibility to provide site-specific information, maintain accessible SDSs, and explain the chemicals employees will encounter. Likewise, HAZWOPER applies to particular hazardous-waste operations and emergency-response activities; it is not a replacement for an ordinary workplace HazCom program.
2024 standard update
Review your program for HCS 2024 changes
OSHA updated the Hazard Communication Standard in 2024 to align primarily with Revision 7 of the Globally Harmonized System. The update affects certain hazard classifications, labels, SDS content, small-container labeling, and trade-secret provisions.
OSHA extended the transition dates in 2026. Employers should review incoming labels and SDSs, then update workplace labels, written HazCom programs, and training where the updated information makes that necessary.
Build safer daily practice
Make chemical safety part of everyday work
A clear written program, current chemical information, and role-appropriate training make it easier for employees to recognize hazards before a routine task becomes an exposure, injury, or citation risk.
