Objective

To understand the hazards associated with plumbing demolition, implement effective control measures, and ensure regulatory compliance to prevent injuries and illnesses.

Introduction

Plumbing demolition, while seemingly straightforward, involves significant hazards, including exposure to hazardous materials like asbestos and lead, as well as risks of structural collapse and injuries from sharp objects. This toolbox talk will cover key safety aspects to ensure a safe work environment.

Hazard Identification

Demolition work involves many of the same hazards that arise during other construction activities; however, demolition also involves additional hazards due to a variety of other factors such as lead-based paint, sharp or protruding objects, and asbestos-containing material. [1]

• Exposure to Asbestos: Asbestos exposure can lead to serious respiratory illnesses, including asbestosis, lung cancer, and mesothelioma.
• Exposure to Lead: Lead exposure can result in lead poisoning, affecting the nervous system, kidneys, and other organs. [2]
• Structural Collapse: Unstable structures can collapse during demolition, causing severe injuries or fatalities. [1]
• Sharp Objects and Protruding Objects: Cuts, lacerations, punctures, and other injuries from nails, broken pipes, and other sharp debris. [1]
• Dust Inhalation: Inhalation of dust can cause respiratory irritation, chronic bronchitis, and other lung problems. [2]

Control Measures

• Asbestos Abatement: Prior to demolition, conduct a thorough inspection for asbestos-containing materials (ACM). If ACM is present, a certified asbestos abatement contractor must remove it following all applicable regulations.
• Lead Hazard Control: Test for lead-based paint. If present, use lead-safe work practices, including wet methods to minimize dust, HEPA vacuums for cleanup, and proper disposal of lead-containing materials. [2]
• Structural Shoring and Bracing: Brace or shore up walls and floors of structures that have been damaged and which employees must enter. [1]
• Dust Control: Use water sprays to suppress dust during demolition activities. [3]
• Opening Protection: Guard wall openings to a height of 42 inches; cover and secure floor openings with material able to withstand the loads likely to be imposed. [1]
• Safe Work Practices: Implement safe work practices, including avoiding standing on top of walls while breaking bricks and ensuring stable footing at all times. [2]

Personal Protective Equipment (PPE) Requirements

• Respiratory Protection: Use appropriate respirators (e.g., N95, half-face, or full-face respirators) when exposed to dust, asbestos, lead, or other airborne contaminants. Ensure proper fit testing and training.
• Eye Protection: Wear safety glasses or goggles to protect against dust, debris, and chemical splashes.
• Hand Protection: Use heavy-duty gloves to protect against cuts, abrasions, and chemical exposure.
• Foot Protection: Wear steel-toed boots to protect against falling objects and punctures.

Real-World Example or Case Study

In 1992, a study of tenement building demolitions in the Bronx, New York, revealed that workers were exposed to significant dust levels containing lead and asbestos due to the lack of dust control measures. This resulted in potential health hazards, including elevated lead levels in workers' blood. [2]

Emergency Procedures

1. In case of asbestos exposure, immediately leave the area and report to the supervisor. Follow established decontamination procedures.
2. In case of injury, administer first aid and seek medical attention.
3. In case of structural collapse, evacuate the area immediately and notify emergency services.

Questions and Answers

• Q: What do I do if I suspect a material contains asbestos?

A: Stop work immediately and notify your supervisor. Do not disturb the material.

• Q: How often should I inspect my PPE?

A: Inspect your PPE before each use to ensure it is in good condition and fits properly.

Summary

Recap of main points:

• Identify and control hazardous materials like asbestos and lead before starting demolition.
• Use appropriate PPE, including respirators, gloves, and eye protection.
• Implement engineering controls such as wet methods and shoring to minimize dust and prevent structural collapse.
• Follow safe work practices and emergency procedures to ensure a safe work environment.

Report all hazards, near-misses, and incidents to your supervisor immediately.
