Compressed Air Safety: Best Practices and Standards
Compressed air is a powerful tool, but it must be used with caution to prevent accidents and injuries. This article outlines key safety guidelines for the use of compressed air, referencing relevant OSHA standards and NFPA guidelines.
Selecting the Right Air Hose
Before using an air hose, ensure it is the correct type. Air hoses can look similar, and using the wrong one can be dangerous. Always verify that the hose is in good condition, free from kinks and damage, especially at connection points where it is most vulnerable.
Maintenance and Storage
Air hoses must be kept in good condition to prevent accidents. Inspect hoses regularly for wear and damage, especially at bends and connections. Store hoses coiled without kinks and hang them over broad supports to prevent damage. Secure connections with wire to prevent accidental disconnections.
Safe Pressure Levels
Use the lowest air pressure necessary for the job. High air pressure can drive debris into the air, causing serious injury. Even at 40 psi, air can cause severe damage if it penetrates the skin, enters body openings, or strikes sensitive areas like the eyes or eardrums.
Handling the Air Hose
Never point the nozzle of an air hose at anyone, including yourself. The nozzle can become a deadly weapon if misused. Always treat compressed air with respect and follow safety guidelines to prevent accidents.
Relevant Standards
OSHA 29 CFR 1926.302(b)(4): This standard outlines the requirements for compressed air and equipment, emphasizing the importance of maintaining hoses and connections in good condition to prevent accidents.
OSHA 29 CFR 1910.242(b): This standard highlights the need for safety in the use of compressed air for cleaning purposes, specifying that air pressure should not exceed 30 psi for cleaning purposes unless effective chip guarding and personal protective equipment are used.
NFPA 70E: This standard addresses electrical safety in the workplace, which includes guidelines for the safe use of electrically powered air compressors.
Conclusion
Compressed air is a valuable tool, but it must be handled with care. Adhering to safety guidelines and relevant standards can prevent accidents and ensure a safe working environment.
