Date: [DATE]
Duration: [DURATION] minutes
Presenter: [PRESENTER NAME]
Location: [LOCATION]
Objective
The objective of this toolbox talk is to educate employees on the safety hazards associated with laying concrete masonry units (CMU) and to provide the necessary control measures and safe work procedures to prevent accidents and injuries. By the end of this talk, participants should be able to identify potential hazards, implement appropriate control measures, and follow safe work procedures to ensure a safe working environment.
Introduction
Laying CMU can be a hazardous task if proper safety precautions are not followed. This toolbox talk will cover the common hazards associated with masonry construction and the steps you can take to protect yourself and your coworkers. It is crucial to understand and adhere to these guidelines to prevent injuries and ensure a safe working environment.
Presenter Note: Engage the audience by asking if anyone has personal experience related to the topic.
Key Points
- Limited Access Zones: Understand and respect limited access zones to prevent unauthorized entry and potential injuries .
- Wall Bracing: Ensure proper bracing of masonry walls to prevent collapse or overturning .
- Personal Protective Equipment (PPE): Always wear the required PPE, including head and face protection when applying cement mixtures .
- Equipment Safety: Use and maintain equipment properly, including masonry saws with appropriate guards .
- Hazard Communication: Be aware of the hazards associated with materials used and follow proper handling procedures .
Hazard Identification
- Wall Collapse: Unbraced masonry walls can collapse, causing serious injuries or fatalities. Ensure walls over eight feet are adequately braced .
- Falling Materials: CMU blocks or tools can fall from heights, striking workers below. Always secure materials and tools properly .
- Impalement Hazards: Protruding reinforcing steel can cause impalement injuries if not guarded properly .
Presenter Note: Encourage participants to share any additional hazards they've encountered.
Control Measures
- Engineering Controls: Use mechanical aids to lift and place CMU blocks to reduce strain and the risk of manual handling injuries.
- Administrative Controls: Implement a limited access zone around the wall being constructed to restrict entry only to essential personnel .
- Personal Protective Equipment (PPE): Wear appropriate PPE, including safety glasses, gloves, and steel-toed boots, to protect against cuts, abrasions, and falling objects .
- Bracing: Ensure that masonry walls over eight feet in height are adequately braced to prevent overturning and collapse. The bracing system should be designed by a registered professional engineer or follow specific requirements .
Safe Work Procedures
- Establish a limited access zone before starting wall construction .
- Ensure all employees actively engaged in constructing the wall are within the limited access zone .
- Brace masonry walls over eight feet in height adequately to prevent overturning and collapse .
- Use appropriate lifting techniques to avoid back injuries when handling CMU blocks.
- Regularly inspect equipment and tools for damage before use .
Presenter Note: If possible, demonstrate the safe work procedure or use visual aids.
Personal Protective Equipment (PPE) Requirements
- Safety Glasses: Wear safety glasses at all times to protect against dust and debris .
- Gloves: Use gloves to protect hands from cuts and abrasions when handling CMU blocks.
- Steel-toed Boots: Wear steel-toed boots to protect feet from falling objects and heavy materials.

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 the specific hazards you've encountered while laying CMU?
- How can we improve our current safety procedures for masonry construction?
- What additional training or resources would be helpful for ensuring our safety?
Presenter Note: Encourage active participation and facilitate the discussion.
Emergency Procedures
- In case of a wall collapse, evacuate the area immediately.
- Provide first aid to any injured workers.
- Report the incident to the supervisor and safety personnel.
- Investigate the cause of the collapse and implement corrective actions.
Questions and Answers
[Encourage participants to ask questions]
[Provide answers to common questions related to the topic]
- Q: What should I do if I see a wall that is not properly braced? A: Report it to your supervisor immediately and do not proceed with work until the issue is resolved.
- Q: How often should I inspect my PPE? A: Inspect your PPE before each use to ensure it is in good condition.
- Q: What is the safe distance for the limited access zone? A: The limited access zone should extend away from the wall a distance equal to the height of the wall plus four feet .
Summary
- Always establish and respect limited access zones .
- Ensure proper bracing for masonry walls over eight feet in height .
- Use appropriate PPE at all times .
- Follow safe work procedures to prevent injuries.
Action Items
- Review and understand the site-specific safety plan for masonry construction.
- Participate in hands-on training for proper bracing techniques.
- Conduct daily inspections of PPE and report any deficiencies.
Remember: Safety is everyone's responsibility. Work safely and look out for your coworkers.
Report all hazards, near-misses, and incidents to your supervisor immediately.
