Toolbox Talk: Lead Safety During Demolition
Date: [DATE] Duration: [DURATION] minutes Presenter: [PRESENTER NAME] Location: [LOCATION]
Objective
The objective of this toolbox talk is to educate workers on the hazards associated with lead exposure during demolition activities and to provide guidelines for safe work practices to minimize these risks. By the end of this talk, participants should be able to identify lead-containing materials, understand the health risks of lead exposure, and implement appropriate control measures and safe work procedures.
Introduction
Lead is a toxic metal that can be found in many older buildings, particularly in paint, plumbing, and other building materials. Demolition activities can disturb these materials, releasing lead dust and fumes into the air, which can be inhaled or ingested by workers. Lead exposure can lead to serious health problems, including neurological damage, kidney damage, and reproductive issues 2, 3. It is crucial to understand the risks and take necessary precautions to protect ourselves and others during demolition work.
Presenter Note: Engage the audience by asking if anyone has personal experience related to the topic.
Key Points
- Lead is a hazardous material commonly found in older buildings [1].
- Demolition activities can release lead dust and fumes into the air [1].
- Exposure to lead can cause serious health problems 2, 3.
- Proper control measures and PPE are essential to minimize lead exposure [2].
- Always follow safe work procedures and report any potential hazards [2].
Hazard Identification
During demolition, several hazards related to lead exposure may be encountered:
- Inhalation of Lead Dust and Fumes: Disturbing lead-based paint or other lead-containing materials can create airborne dust and fumes, leading to inhalation and potential respiratory and systemic health effects [2].
- Ingestion of Lead Contaminants: Lead dust can settle on surfaces and be ingested through hand-to-mouth contact, especially if hygiene practices are not followed [2].
- Skin Contact with Lead-Containing Materials: Although less common, direct skin contact with lead-containing materials can result in absorption and localized irritation [2].
Presenter Note: Encourage participants to share any additional hazards they've encountered.
Control Measures
To minimize lead exposure during demolition, implement the following control measures:
- Engineering Controls: Use local exhaust ventilation and dust collection systems to capture lead dust and fumes at the source [2].
- Administrative Controls: Develop and implement a written lead safety program, provide training to workers, and establish hygiene practices such as handwashing and changing out of work clothes before leaving the work site [2].
- Personal Protective Equipment (PPE): Provide and ensure the use of appropriate PPE, including respirators, gloves, and protective clothing [2].
- Containment: Use containment methods, such as plastic sheeting and barriers, to prevent the spread of lead dust to other areas [2].
Safe Work Procedures
- Identify Potential Lead-Containing Materials: Before starting demolition, conduct a thorough inspection to identify any materials that may contain lead [2].
- Establish a Work Zone: Clearly mark and isolate the work area to prevent unauthorized access and minimize the spread of contamination [2].
- Use Dust Control Measures: Employ wet methods, such as spraying water, to suppress dust during demolition activities [2].
- Wear Appropriate PPE: Always wear a properly fitted respirator, gloves, and protective clothing when working in areas with potential lead exposure [2].
- Practice Good Hygiene: Wash hands and face thoroughly with soap and water before eating, drinking, or smoking, and at the end of each shift [2].
Presenter Note: If possible, demonstrate the safe work procedure or use visual aids.
Personal Protective Equipment (PPE) Requirements
- Respirator: Use a NIOSH-approved respirator appropriate for the level of lead exposure. Ensure proper fit testing and training on respirator use and maintenance [2].
- Gloves: Wear disposable gloves to prevent skin contact with lead-containing materials. Change gloves regularly and dispose of them properly [2].
- Protective Clothing: Wear disposable coveralls or other protective clothing to prevent contamination of personal clothing. Remove and dispose of clothing properly at the end of each shift [2].

Real-World Example or Case Study
[Provide a detailed description of a relevant real-world scenario or case study]
[Discuss what went wrong or right, and the lessons learned]
Presenter Note: Ask participants if they can relate this example to their own experiences.
Group Discussion
Discuss the following questions:
- What are some common materials in older buildings that may contain lead?
- What are the potential health effects of lead exposure?
- What steps can we take to minimize lead exposure during demolition activities?
Presenter Note: Encourage active participation and facilitate the discussion.
Emergency Procedures
In case of an emergency related to lead exposure:
- Stop Work: Immediately stop work and evacuate the area if a significant release of lead dust or fumes occurs [2].
- Seek Medical Attention: If you experience symptoms of lead exposure, such as nausea, headache, or fatigue, seek medical attention immediately [3].
- Report the Incident: Report any lead-related incidents or exposures to your supervisor and safety personnel [2].
- Decontaminate: Follow proper decontamination procedures to remove lead dust from clothing and equipment [2].
Questions and Answers
[Encourage participants to ask questions]
[Provide answers to common questions related to the topic]
- Q: What type of respirator should I use when working with lead-based paint? A: A NIOSH-approved respirator with a HEPA filter is recommended for working with lead-based paint [2].
- Q: How often should I change my gloves when working with lead-containing materials? A: Change gloves regularly, especially if they become torn or contaminated [2].
- Q: What should I do if I accidentally ingest lead dust? A: Do NOT induce vomiting. Call a physician or poison control center immediately [3].
Summary
[Recap the main points covered in the toolbox talk]
- Lead exposure during demolition can cause serious health problems 2, 3.
- Proper control measures, including engineering controls, administrative controls, and PPE, are essential to minimize lead exposure [2].
- Safe work procedures, such as dust control, hygiene practices, and proper PPE use, must be followed at all times [2].
- Report any potential hazards or lead-related incidents to your supervisor immediately [2].
Action Items
[List specific actions participants should take following this toolbox talk]
- Review the site-specific lead safety plan.
- Inspect your PPE to ensure it is in good condition and fits properly.
- Report any potential lead hazards to your supervisor.
Remember: Safety First, Every Task, Every Time!
Report all hazards, near-misses, and incidents to your supervisor immediately.
