Understanding Respiratory Hazards in Construction

Feb 22, 2025

Overview of Respiratory Hazards in Construction and Protection Program Requirements

Introduction

  • OSHA Requirements: Employers must have respiratory protection programs if respirators are required for their workers.
  • Training: This video can be part of the OSHA-required respiratory protection training.
  • Purpose of Respirators: Protect workers' health and safety from respiratory hazards present at construction sites.

Types of Respiratory Hazards

  • Quick-acting hazards: e.g., Carbon Monoxide (can cause unconsciousness or death within minutes).
  • Long-term hazards: e.g., Asbestos (can cause lung cancer decades after exposure).
  • Other Examples:
    • Lead dust and fumes (from grinding, welding, cutting).
    • Silica dust (from cutting concrete, sandblasting).
    • Solvent vapors (from adhesives, paints, cleaning solvents).
    • Isocyanate vapors (from spray foam insulation and certain paints).

Methods to Reduce Exposure

  • Engineering Controls: e.g., local exhaust ventilation.
  • Work Practice Controls: e.g., using wet cutting techniques.
  • Administrative Controls: Minimizing the number of workers exposed.

Respiratory Protection Program

  • Respirator Selection: Must be based on the specific hazard.
    • Filtering Facepiece Respirators: Protect against particulate hazards.
    • Air-Purifying Respirators with Chemical Cartridges: For gases and vapors.
    • Atmosphere-Supplying Respirators: For hazardous atmospheres (e.g., CO, lack of oxygen).

Employer Responsibilities

  • Develop and implement a written respiratory protection program.
  • Evaluate workplace respiratory hazards.
  • Select and provide appropriate respirators.
  • Provide medical evaluations and fit testing.
  • Maintain and clean respirators.
  • Provide training on hazards and respirator use.
  • Evaluate respirator use and address issues.
  • Provide access to specific records/documents.

Training and Program Management

  • Additional Training: Worksite-specific training is required.
  • Program Administrator: Must be qualified and trained to manage the program.
    • Tasks: Monitor the program, ensure adequate protection, answer questions, evaluate and update the program as needed.

Adaptation to Workplace Changes

  • Update program to account for changes:
    • New work patterns or techniques.
    • Use of new building materials or chemicals.
    • Changes in hazard levels or respirator types.
  • Notify supervisor if changes conflict with training or policies.

Conclusion

  • The video provides a brief overview, but further training is required.
  • Consult supervisors if unsure about respirator needs or usage.
  • Additional resources are available on OSHA and NIOSH websites for more detailed guidance.
