Hazard Communication (HazCom) and GHS

For employees who work with or near hazardous chemicals, and their supervisors: read labels and SDSs, choose controls, and respond safely under OSHA's 2024 HazCom rule.

For: Employees exposed to hazardous chemicals in any general industry setting (manufacturing, warehousing, cleaning and custodial, laundry, auto body, food production, hospitality, maintenance) and the supervisors who direct their work

What you will be able to do

  • Explain what the 2024 Hazard Communication Standard requires of employers and guarantees to employees, including the written program, chemical list, training triggers, multi-employer duties and phased compliance dates.
  • Interpret shipped-container and workplace labels, including the six required label elements, signal words and the eight HCS pictograms, and determine when a container needs a workplace label.
  • Locate hazard, first-aid, spill, storage, exposure-limit and PPE information in the correct section of a 16-section Safety Data Sheet.
  • Identify routes of exposure, acute and chronic health effects and physical hazards, and describe the purpose and limits of PELs, RELs and TLVs.
  • Select chemical controls using the hierarchy of controls, and apply correct PPE use, storage, handling and non-routine task precautions.
  • Respond to chemical spills, splashes and exposures within the limits of your training, and report hazards and injuries knowing your protection from retaliation.

Learn to read any GHS label in 30 seconds, find the answer you need on a 16-section Safety Data Sheet in under a minute, and decide when a spray bottle needs its own label. You will practice with real-world exercises: spot the errors on a shipped-container label, audit a storeroom, sort SDS questions into the right section, and make the calls in a branching spill scenario.

Built for workers who handle or work near hazardous chemicals, and for the supervisors and leads who set up their tasks. Every module follows a different US workplace, from a San Antonio laundry to a Portland brewery, and ties each lesson to the exact paragraph of OSHA's Hazard Communication Standard, 29 CFR 1910.1200, as revised in 2024.

Hazard Communication ranked second on OSHA's list of most frequently cited standards for fiscal year 2026. This awareness course covers the 2024 changes and the current phased compliance dates (updated after OSHA's January 2026 extension), and is honest about its limits: your employer must still provide site-specific training on your chemicals, labeling system and emergency procedures. Five practical job aids, including a chemical JHA worksheet and a training sign-off record, help make that happen.

What you’ll be able to do Monday morning

  1. Read any chemical label in 30 seconds and stop work if a required element is missing.
  2. Find the SDS for each chemical you use, on your shift, and pull PPE, spill and first-aid steps from sections 8, 6 and 4.
  3. Label every secondary container that someone else will use or that will outlast your shift.
  4. Check that incompatible chemicals are stored apart and that the eyewash path is clear.
  5. Ask for a briefing, or complete a chemical JHA, before any non-routine chemical task.
  6. Report spills, near misses, missing labels and symptoms through your site's process.

Leak in aisle 14

You are Tom Nguyen, an order picker on night shift at a distribution center near Memphis, Tennessee. A forklift has punctured a 5-gallon pail of concentrated drain opener on a second-level shelf. Liquid is dripping onto cardboard cases and spreading across the floor. Your coworker Jasmine is walking over with a broom and paper towels.

Credit and approval status

Certificate of completion

This course awards a certificate of completion for 2 contact hours of instruction. It has not been approved or accredited by OSHA, any state OSHA program, IACET, BCSP or any licensing board, and it is not OSHA Outreach Training Program (10- or 30-hour) training. It is awareness training on the general requirements of 29 CFR 1910.1200; OSHA requires your employer to add training on the specific chemicals, labeling system and procedures at your workplace. Check with your employer, board or safety program whether this course can count toward your training records or continuing education.

Pathways we are pursuing or may pursue include IACET accreditation of our course development process and, where eligible, recognition for safety professional recertification. No approval exists today; we will show any approval on this page only after it is granted.

Questions about this course

Is this course OSHA-required HazCom training?

OSHA requires employers to train employees on hazardous chemicals at initial assignment and when new hazards are introduced. This course covers the general requirements of 29 CFR 1910.1200 that apply everywhere. It cannot replace the site-specific part: your chemicals, your SDS location, your labeling system and your emergency procedures. Your employer must add that, and our training sign-off record helps document it.

Does this course include the 2024 HazCom changes?

Yes. It covers the 2024 final rule aligned primarily with GHS Revision 7, including new small-container and released-for-shipment label provisions, and the current phased compliance dates after OSHA's January 2026 four-month extension: employers must update workplace labels, programs and training by November 20, 2026 for substances and May 19, 2028 for mixtures.

Will I get continuing education credit or an OSHA card?

No. You receive a certificate of completion for 2 contact hours of instruction. The course is not approved or accredited by OSHA, a state agency, IACET or a licensing board, and it is not OSHA Outreach (10- or 30-hour) training, so no OSHA card is issued. Check with your employer or board whether the certificate counts toward your training records.

Who should take this course?

Anyone who works with or near hazardous chemicals in general industry, such as cleaning and custodial staff, warehouse and receiving workers, maintenance technicians, laundry, auto-body, food production and hospitality staff, and the supervisors and leads who assign chemical tasks. It is foundational level, with no prior safety training needed.

How long does it take, and can I pause?

Plan on about two hours: eight short modules of roughly 11 to 13 minutes each, including interactive exercises and knowledge checks, plus a 23-question final assessment. You need 80% to pass. You can pause between modules and pick up where you left off.

Does it cover my state's rules?

The course teaches the federal standard. If you work in one of the 29 State Plan states or territories, your state program enforces its own HazCom rule, which must be at least as effective as federal OSHA's and may differ. The course explains which states run State Plans and what to check locally.

This course is general education and safety awareness training from CE Courses Hub. It is not legal, medical or professional advice and does not replace your employer's hazard communication program, site-specific training, safety policies, or advice from a qualified safety or health professional. It is not OSHA Outreach Training Program (10- or 30-hour) training. Completing it earns a certificate of completion for the stated contact hours; it is not approved or accredited by any licensing board, state agency or accreditor unless an approval is shown on the course page. Check with your board, employer or state agency whether this course meets your specific requirement.
