Compressed Air Cleaning and Flying Debris
Compressed Air Is Not a Personal Cleaning Tool
A quick blast of compressed air can turn settled chips and dust into an exposure for the person cleaning and anyone nearby. Never direct an air nozzle at a person or use it to clean skin or clothing. A reduced pressure setting does not make that practice safe. Choose a suitable vacuum or another approved cleaning method wherever practicable. When compressed air is authorised for equipment cleaning, pressure control, effective chip guarding and suitable protective equipment must work together. Stop if debris can escape towards people.
Controls to confirm
- Keep compressed air away from skin, clothing and other people. Use a cleaning method suitable for the material and its hazards; a vacuum must be approved for the dust or debris being collected.
- For authorised equipment cleaning, use an approved safety nozzle and pressure-control arrangement that meets the applicable limit. OSHA general-industry guidance requires less than 30 psi for cleaning; have a competent person verify the arrangement, including blocked-nozzle conditions. Do not block nozzle relief openings or improvise modifications.
- Provide effective chip guarding or barriers that contain flying particles and protect nearby workers. Wear eye and other protective equipment selected for the task, and control access to the cleaning area before starting.
Today’s action
Check the cleaning method at one workstation today. Replace any practice of blowing down people or clothing with an approved method, and resolve any unverified nozzle, pressure control or chip guard before air cleaning begins.
