Safe Use of Compressed Air for Cleaning

Tools & Equipment
English (Canada)

The Problem

Compressed air blowers are commonly used for cleaning, but they can pose serious hazards if misused. High-pressure air can cause injuries such as eye damage, skin punctures, and even internal injuries if forced under the skin. Misuse of compressed air can also endanger others by sending debris flying. Today, we’ll identify these hazards and discuss the proper safety procedures to ensure everyone works safely with compressed air.

Identify the Hazards

  • High-Pressure Injuries: Directing air at the skin can cause air embolisms, leading to internal injuries. Air can puncture the skin and cause serious damage.
    ‍
  • Flying Debris: Loose particles can become projectiles, causing cuts, abrasions, or eye injuries.
    ‍
  • Misuse and Horseplay: Pointing compressed air at others or yourself can result in serious harm.
    ‍
  • Damaged Equipment: Cracked hoses or faulty nozzles can result in unexpected high-pressure bursts.

    • Safety Practices and Preventative Measures

  • Use Compressed Air Correctly:
    • Pressure Limitation: Never exceed 30 psi (200 kPa) when using compressed air for cleaning. Use a pressure regulator when required.
    • No Air on the Body: Never use compressed air to clean your skin or clothing—it can cause internal injuries.
    • No Horseplay: Never direct compressed air at yourself or coworkers. Misuse of compressed air can have life-threatening consequences.
  • Use Proper Personal Protective Equipment (PPE):
    • Eye Protection: Always wear safety glasses or a face shield to protect against flying debris.
    • PPE for Others: Ensure others nearby are wearing PPE to stay protected.
  • Control the Work Area:
    • Barriers and Shields: Place barriers between yourself and others to block flying debris.
    • Clear the Area: Make sure the area is free of people, sensitive equipment, or materials that could be harmed.
  • Use Safety-Equipped Tools:
    • Safety Nozzles: Always use blowers with safety tips or nozzles that divert air to relief ports if blocked.
    • Inspect Equipment: Before use, inspect hoses and nozzles for wear or damage. Do not use faulty equipment.
  • Follow General Safety Guidelines:
    • Safe Direction: Always point the air nozzle away from people, animals, and fragile objects.
    • Maintain Distance: Stay a safe distance from the nozzle and avoid directing air at surfaces that could cause debris to rebound.

    • Real-Life Case or Scenario

    Where possible, use an actual incident that you have experienced or been involved in.

    A worker used compressed air to blow dust off his clothes, believing it was harmless. The high-pressure air penetrated his skin, causing an air embolism. He required immediate medical attention to prevent life-threatening complications. This incident could have been prevented by understanding the risks and following safe practices.

    Employee Responsibilities

    • Use compressed air blowers only for their intended purpose.
      ‍
    • Inspect equipment for damage before use.
      ‍
    • Follow all PPE requirements, including wearing safety glasses or face shields.
      ‍
    • Never engage in horseplay with compressed air.
      ‍
    • Report damaged equipment or unsafe practices to your supervisor immediately.

    Employer Responsibilities

    • Provide tools equipped with safety nozzles and pressure regulators.
      ‍
    • Train workers on the safe use of compressed air and associated hazards.
      ‍
    • Inspect and maintain all compressed air equipment regularly.

    Discussion & Questions

    • Why do you think Canadian safety guidelines limit compressed air to 200 kPa (30 psi) for cleaning purposes?
    • Has anyone ever witnessed or experienced an incident caused by compressed air misuse? What happened?

    Encourage workers to share ideas on improving compressed air safety in the workplace.

    Commitment/Action Plan

    Let’s commit to following these compressed air safety rules every day. Before starting work, inspect your air tools, use proper PPE, and remind your coworkers of these guidelines. Safety begins with each of us.

    Wrap-Up

    Compressed air may seem harmless, but it can cause serious injuries if used improperly. By following these safety measures, we can protect ourselves and others. Thank you for making safety a shared priority.

    Standards Overview

  • Pressure Limitation: Canadian safety guidelines recommend that compressed air used for cleaning should not exceed 30 psi (approximately 200 kPa) and must be fitted with a pressure-reducing nozzle or air gun.
    ‍
  • Safety Nozzles: Nozzles must include safety features to prevent dead-ending and reduce risk.
    ‍
  • Training: Employers must provide training on the hazards and proper use of compressed air tools in accordance with applicable provincial occupational health and safety regulations and CCOHS guidance
