Before using any hazardous chemical, workers should review both the container label and the Safety Data Sheet (SDS). Together, these documents provide the information needed to identify chemical hazards, understand safe handling procedures, select the correct personal protective equipment (PPE), and respond appropriately in an emergency. Taking a few minutes to review this information before starting work can prevent serious injuries and exposures.
This toolbox talk reviews the importance of reading chemical labels and SDSs before handling hazardous chemicals.
Why This Matters
- Labels and SDSs provide critical information about chemical hazards.
- Reviewing hazard information helps workers select the correct PPE and safe work practices.
- Understanding emergency procedures improves response to spills, fires, or exposures.
- Proper hazard identification reduces the risk of chemical injuries and illnesses.
- Reviewing chemical information supports compliance with Hazard Communication requirements.
Common Hazards
- Using chemicals without reading the label or SDS.
- Missing or unreadable container labels.
- Using outdated or incorrect Safety Data Sheets.
- Selecting incorrect PPE because hazard information was not reviewed.
- Mixing incompatible chemicals.
- Improper storage of hazardous substances.
- Failure to understand first aid or spill response procedures.
- Assuming familiar chemicals present no hazards.
Safety Checklist
Before Using a Chemical
- Read the container label and verify the chemical identity.
- Review the Safety Data Sheet (SDS) for health hazards, physical hazards, and safe handling instructions.
- Identify the required PPE before beginning work.
- Understand storage requirements and incompatible materials.
- Review first aid measures, spill response procedures, and emergency contact information.
- Verify the container is properly labeled and in good condition.
During Work
- Follow all precautions listed on the label and SDS.
- Use chemicals only as intended and according to company procedures.
- Keep chemical containers closed when not in use.
- Report missing labels, damaged containers, or unavailable SDSs immediately.
- Review the SDS again if unfamiliar conditions or questions arise during the task.
- Ask your supervisor whenever you are uncertain about a chemical hazard or required protective measures.
Crew Talking Points
- Where are today's Safety Data Sheets located?
- What hazards are identified on the chemical label?
- What PPE is required for the chemicals being used?
- What first aid procedures apply if an exposure occurs?
- What should you do if a chemical container is missing its label?
- Speak up immediately if you cannot locate an SDS or do not understand the hazard information.
Stop Work If
- A chemical container is missing or has an unreadable label.
- The required Safety Data Sheet (SDS) is unavailable.
- You do not understand the hazards or safe handling procedures.
- Required PPE or engineering controls are unavailable.
- A chemical appears to be improperly stored or damaged.
- You are unsure how to safely use the chemical.
Final Reminder
The label and Safety Data Sheet are your primary sources of chemical safety information. Review them before every task, understand the hazards, wear the required PPE, and follow the recommended handling, storage, and emergency procedures. If the information is missing or unclear, stop work and get clarification before proceeding.
