Hazard Communication (HazCom)
Overview
Hazard Communication (HazCom) ensures workers understand chemical hazards in their workplace and know how to protect themselves from exposure. This system includes labeling, safety data sheets (SDS), and training to prevent chemical-related injuries and illnesses.
Why This Is Important
Chemical exposures can cause immediate injuries like burns and respiratory problems, or long-term health effects including cancer and organ damage. Without proper information and training, workers cannot make informed decisions about protection and safe handling practices.
HazCom provides the foundation for chemical safety by ensuring everyone understands what they’re working with and how to stay safe. This knowledge empowers workers to protect themselves and respond appropriately to chemical emergencies.
Best Practices & Safety Tips
Read Safety Data Sheets (SDS)
Read and understand SDS before working with any chemical. They provide essential information about hazards, handling procedures, and emergency response.
Use Appropriate PPE
Use the personal protective equipment recommended by the SDS and workplace assessments. Different chemicals require different levels of protection.
Label Containers Properly
Ensure all chemical containers are properly labeled with hazard information. Never use unlabeled containers or remove existing labels.
Store Chemicals Safely
Store chemicals according to manufacturer instructions and compatibility requirements. Separate incompatible materials to prevent dangerous reactions.
Key HazCom Components
Safety Data Sheets (SDS)
- Must be available for every hazardous chemical in the workplace
- Contain 16 standardized sections covering hazards, handling, and emergency procedures
- Updated versions must be obtained when available from manufacturers
- Workers must know how to access and interpret SDS information
Chemical Labels and Pictograms
- All containers must have proper hazard labels
- GHS pictograms provide visual hazard warnings
- Signal words (Danger/Warning) indicate severity level
- Hazard and precautionary statements explain specific risks and safety measures
Employee Training Requirements
- Initial training before exposure to hazardous chemicals
- Additional training when new chemicals are introduced
- Training must cover hazard recognition, protective measures, and emergency procedures
- Workers must understand how to use HazCom information effectively
Chemical Safety Protocols
- Never mix chemicals unless specifically instructed by manufacturer procedures
- Immediately report chemical spills, leaks, or exposures to supervisors
- Use proper ventilation systems to reduce airborne chemical concentrations
- Wash hands thoroughly after handling chemicals, even when wearing gloves
- Know the location of emergency equipment (eyewash stations, safety showers, spill kits)
- Follow proper disposal procedures for chemical wastes according to regulations
Discussion Questions
- What chemicals do you work with regularly, and where do you find hazard information about them?
- How do you access and use Safety Data Sheets when you need chemical information?
- What would you do if you discovered an unlabeled chemical container in your work area?
- How can we improve chemical storage and organization to reduce hazards and improve safety?
- What steps would you take if you or a coworker were accidentally exposed to a hazardous chemical?
Action Items
- Verify all chemical containers have proper labels and hazard information
- Ensure current SDS are available and accessible for all workplace chemicals
- Review emergency procedures for chemical exposures and spill response
- Confirm all workers have received required HazCom training and understand procedures
