The Hazard Communication Standard (HazCom) requires employers to identify chemical hazards in the workplace and communicate those risks to employees. This article outlines practical steps employers must take to meet HazCom obligations under OSHA, including labeling, safety data sheets, training, and program documentation. By aligning with the Globally Harmonized System (GHS) guidelines and federal OSHA requirements, employers can reduce chemical exposure risks and enhance workplace safety.
Understand The HazCom Standard And Its Scope
HazCom applies to workplaces where employees may be exposed to hazardous chemicals under normal or foreseeable conditions. It covers chemical manufacturers, distributors, importers, and employers who use chemicals in their processes. Key goals are to ensure employees receive information on chemical hazards, protective measures, and safe handling practices. The standard emphasizes standardized labeling, hazard communication through safety data sheets (SDS), and worker training. Understanding scope helps employers tailor their programs to the specific chemicals and operations present in the workplace.
Ensure Proper Classification And Labeling
All hazardous chemicals must be properly classified to determine the appropriate hazard warnings. Employers should evaluate chemical products to identify health, physical, and environmental hazards. This classification informs label content and SDS requirements. Under HazCom and GHS, labels must include symbols (pictograms), Signal Words, Hazard Statements, and Precautionary Statements. For mixtures, manufacturers may provide a consolidated label, but employers must ensure any company-specific labeling aligns with HazCom requirements.
Labels And Pictograms
Labels should be durable and clearly legible. Each label must feature pictograms that convey the specific hazard, along with a Signal Word (such as Danger or Warning) and concise hazard statements. Employers should verify that labels on incoming containers and secondary containers accurately reflect the hazards and are not obscured or altered during substitutions or transfers.
Safety Data Sheets (SDS)
SDS provide comprehensive hazard information, including composition, handling, exposure controls, and emergency measures. Employers should keep SDS readily accessible to all affected employees, typically through a centralized library or digital portal. SDS updates should be tracked, and employees should be notified when a new SDS is issued for a chemical they use.
Provide Hazard Communications—Labels And Safety Data Sheets
HazCom requires two core information streams: labels on chemical containers and SDSs that accompany the chemical. When chemicals are transferred to workplace containers, employers must ensure that containers are labeled or that the owner’s label is retained. If a product’s label is removed or altered, a replacement label must be applied. The organization must maintain an accessible SDS repository and ensure that employees know where to locate it.
Employee Training And Information
Training is essential to HazCom compliance. Employers should provide initial training for new hires and refresher training for current workers whenever new hazards are introduced or processes change. Training topics commonly include understanding hazard classifications, reading labels and SDSs, safe handling and storage practices, emergency procedures, and the rights and responsibilities under HazCom. Training should be delivered in plain language and reinforced with practical demonstrations and accessible resources.
Key Training Elements
- How to interpret label elements, pictograms, and signal words
- Locations and use of the SDS and how to access it
- Proper storage, handling, and disposal of chemicals
- Emergency response procedures and first-aid measures
- Methods to control exposures, including engineering controls and PPE
- Worker rights and how to report hazards or concerns
Written Hazard Communication Program And Documentation
Employers must develop and implement a written HazCom program that outlines how the organization meets labeling, SDS management, training, and exposure assessment requirements. This program should identify roles and responsibilities, communication procedures, and the process for updating information when products change. Documentation should include inventory of hazardous chemicals, location-based hazard communication plans, and records of training sessions, inspections, and incident investigations.
Program Structure Essentials
- A current chemical inventory with hazard classifications
- A schedule for reviewing and updating labels and SDSs
- Procedures for labeling and re-labeling when containers are repurposed
- Methods for ensuring accessibility of the SDS library to all workers
- Plans for periodic audits and corrective actions
Supplier And Workplace Labels And Sds Management
To meet HazCom standards, employers must rely on supplier labels and SDSs for freshly received chemicals and maintain internal controls for any in-house labeling. When products are mixed or repackaged, it is essential to apply appropriate internal labels that reflect the hazards accurately. Regularly verify that SDSs match the actual chemical contents and that updates from suppliers are promptly incorporated. Implement a systematic approach to document control, ensuring that outdated or superseded information is removed from circulation.
Ongoing Compliance And Audits
Compliance is an ongoing process that requires periodic reviews, audits, and corrective actions. Employers should conduct routine workplace inspections to verify labeling accuracy, SDS accessibility, and training effectiveness. Internal audits help detect gaps in labeling, storage, or exposure controls and verify that hazard communication materials reflect current classifications. Management should address findings promptly with targeted corrective actions, updated procedures, and renewed training as needed.
Practical Best Practices For HazCom Readiness
- Integrate HazCom requirements into the safety management system and incident reporting
- Adopt a centralized electronic SDS library with offline access for areas with limited connectivity
- Use standardized labeling across all containers, including secondary containers
- Schedule annual refresher training and document completion
- Engage workers in hazard assessment and labeling decisions to improve buy-in
