Identifying Lead-Based Materials Toolbox Talk

Lead has been widely used in paints, coatings, pipes, solder, roofing materials, and other building products. Although many modern materials no longer contain lead, older structures and equipment may still present significant exposure hazards. Workers should never assume a material is lead-free based on its appearance. Before disturbing painted or coated surfaces, a lead assessment, testing, or review of available building records should be completed when appropriate.

This toolbox talk reviews how to recognize potential lead-containing materials, understand their hazards, and safely respond when lead may be present.

Why This Matters

• Lead exposure can cause serious health effects affecting the nervous system, kidneys, blood, and reproductive system.
• Lead dust and fumes are often invisible and can be inhaled or swallowed.
• Many older buildings and structures still contain lead-based materials.
• Identifying lead hazards before work begins helps prevent worker exposure.
• Proper hazard assessments allow appropriate controls to be implemented.

Common Hazards

• Sanding, grinding, cutting, or blasting painted surfaces that contain lead.
• Welding or torch cutting lead-coated or painted metal.
• Demolishing older structures without evaluating lead hazards.
• Creating lead dust during renovation or maintenance work.
• Using compressed air or dry sweeping to clean lead-contaminated dust.
• Handling lead-containing materials without proper hygiene practices.
• Assuming painted materials do not contain lead because they appear new or undamaged.
• Failing to report suspect lead-containing materials before work begins.

Safety Checklist

Before Work Begins

• Determine whether lead assessments, testing results, or building records are available for the work area.
• Identify painted, coated, or older building materials that may contain lead.
• Review the work plan to determine whether lead-containing materials could be disturbed.
• Ensure appropriate exposure controls and personal protective equipment are available if lead hazards are identified.
• Verify workers have received required lead hazard awareness or task-specific training.
• Treat suspect materials as potentially containing lead until confirmed otherwise.

During Work

• Follow approved lead-safe work practices whenever disturbing known or suspected lead-containing materials.
• Use dust control measures and engineering controls as required.
• Do not use dry sweeping or compressed air to clean lead dust unless specifically permitted under controlled procedures.
• Maintain good housekeeping to prevent the spread of contamination.
• Report previously unidentified suspect lead-containing materials immediately.
• Stop work if conditions differ from the hazard assessment or required controls are unavailable.

Crew Talking Points

• What materials on today's job may contain lead?
• Has the work area been evaluated for lead hazards?
• What activities could generate lead dust or fumes?
• What controls are being used to reduce lead exposure?
• Who should be notified if suspected lead-containing materials are discovered?
• Speak up immediately if you believe your work could disturb lead-containing materials.

Stop Work If

• Previously unidentified suspect lead-containing materials are discovered.
• Required lead hazard assessments or testing have not been completed.
• Engineering controls or required PPE are unavailable or ineffective.
• Work activities begin generating uncontrolled lead dust or fumes.
• The work scope changes beyond what has been evaluated for lead hazards.
• You are unsure whether materials contain lead.

Final Reminder

You cannot determine whether a material contains lead simply by looking at it. Always review available hazard information before starting work, treat suspect materials with caution, follow approved lead-safe work practices, and report any unidentified lead hazards immediately. When in doubt, stop work until the material has been properly evaluated.
