Hazard Communication 29 CFR 1910.1200

Course Overview

Updated for the 2024 rule. This course is taught to the current version of OSHA 29 CFR 1910.1200 as amended by the final rule of 20 May 2024 (89 FR 44144), aligned with GHS Revision 7, and reflects the compliance-date extension OSHA issued on 15 January 2026.

The Hazard Communication 29 CFR 1910.1200 course from the American Institute of Safety Professionals provides comprehensive training on OSHA 29 CFR 1910.1200, the standard that establishes the worker's right to know about the hazardous chemicals in their workplace. Hazard Communication (HazCom) is consistently among the top five most frequently cited OSHA standards across all industries because it applies to virtually every workplace that uses or stores hazardous chemicals — which is virtually every workplace. From the cleaning products in an office to the process chemicals in a refinery, if hazardous chemicals are present, HazCom applies.

The standard was first aligned with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) in 2012, adopting GHS Revision 3. On 20 May 2024, OSHA published a final rule (89 FR 44144) updating the standard to align with GHS Revision 7, which took effect on 19 July 2024 and introduced revised classification criteria, new labeling provisions and updated Safety Data Sheet requirements.

The HazCom standard requires four integrated components: a written hazard communication program, a chemical inventory listing every hazardous chemical in the workplace, Safety Data Sheets (SDS) for every hazardous chemical (accessible to all employees during every shift), and employee training on chemical hazards and protective measures. GHS alignment standardized the format for both labels and SDS: GHS labels use pictograms, signal words (Danger or Warning), hazard statements, and precautionary statements in a standardized format, while SDS follow a mandatory 16-section format that ensures consistency across every chemical from every manufacturer worldwide. The 2024 revisions refine this further, introducing the released-for-shipment labeling provision, reduced label content on containers of 100 ml or less, and alternative label formats such as pull-out, fold-back or tie-on labels on containers of 3 ml or less.

The curriculum covers the HazCom standard requirements (1910.1200), the written hazard communication program (required elements, multi-employer worksite provisions), chemical inventory development and maintenance, the 16-section SDS format (section-by-section guidance on reading and interpreting SDS), GHS label elements (product identifier, pictograms, signal words, hazard statements, precautionary statements, supplier identification), the nine GHS pictograms and the hazards each represents, hazard classification system (physical hazards, health hazards, environmental hazards, hazard categories and severity), workplace container labeling (shipped containers versus workplace containers, secondary labeling alternatives), employee training requirements (1910.1200), non-routine tasks and unlabeled pipes, trade secret provisions, and the program management that sustains HazCom compliance over time.

All training is delivered 100 percent online through the American Institute of Safety Professionals Student Dashboard. Upon successful completion, graduates receive an American Institute of Safety Professionals certificate, professional wallet card, and official transcript, all employer-verifiable at amiosp.com/student-verifications.

What the 2024 Update Changed

Classification

• Desensitized explosives introduced as a new physical hazard class
• Aerosols revised and expanded to cover chemicals under pressure
• Flammable gases divided into Categories 1A and 1B, including pyrophoric gas and chemically unstable gas
• Revised Appendix A (health hazards) and Appendix B (physical hazards)

Labeling

• Released-for-shipment provision for product already packaged
• Reduced label content permitted on containers of 100 ml or less
• Pull-out, fold-back or tie-on labels permitted on containers of 3 ml or less
• Revised Appendix C

Safety Data Sheets

• Section 9 reordered and expanded
• Trade secret disclosures must fall within prescribed concentration ranges
• Revised Appendix D

Compliance Dates

All four compliance dates were extended by four months by OSHA's final rule of 15 January 2026. Until the applicable date, employers may comply with the 2012 standard, the 2024 standard, or both.

Learning Outcomes

Upon completing this program, participants will be able to:

• Explain the purpose and scope of OSHA 29 CFR 1910.1200: the right-to-know principle, which employers and chemicals are covered, alignment with GHS Revision 7 under the 2024 final rule, and why HazCom is one of the most cited OSHA standards.
• Develop and maintain the written hazard communication program: the required elements (chemical inventory, SDS management, labeling, training, non-routine tasks, pipes), multi-employer worksite provisions, and the written program as an auditable document.
• Develop and maintain the chemical inventory: listing every hazardous chemical present in the workplace, matching inventory to SDS collection, and the annual review process.
• Read and interpret all 16 sections of a Safety Data Sheet: Identification, Hazard Identification, Composition, First Aid, Firefighting, Accidental Release, Handling and Storage, Exposure Controls/PPE, Physical/Chemical Properties, Stability/Reactivity, Toxicological, Ecological, Disposal, Transport, Regulatory, and Other information.
• Interpret GHS label elements: product identifier, pictograms, signal words (Danger/Warning), hazard statements (H-statements), precautionary statements (P-statements), and supplier identification.
• Identify the nine GHS pictograms: flame, flame over circle, exploding bomb, corrosion, skull and crossbones, health hazard, exclamation mark, gas cylinder, and environment — and the hazard categories each represents.
• Apply the hazard classification system: physical hazards (including desensitized explosives introduced by the 2024 rule), health hazards (10 classes), and how hazard categories determine the signal word and pictogram.
• Manage workplace container labeling: shipped container labels, workplace/secondary container labeling (NFPA/HMIS alternatives), and the immediate-use exemption.
• Deliver effective HazCom employee training per 1910.1200: required training content, timing (initial assignment and new hazards), and documentation.
• Manage HazCom for non-routine tasks and unlabeled pipes: informing employees before non-routine work and communicating pipe hazards.
