According to OSHA standards, compressed air shall not be used for cleaning purposes except when?

• A. less than 30 psi and with chip guarding
• B. less than 50 psi and with chip guarding
• C. less than 30 psi
• D. less than 50 psi

Answer: (A)

The key safety rule is that compressed air can be used for cleaning only under strict conditions to prevent injury from flying debris. OSHA requires the air pressure to be very low (less than 30 psi) and for there to be an effective chip guarding in place to contain and deflect any chips or dust. That combination is what makes cleaning with compressed air acceptable in very limited situations. So the correct option is the one that specifies both conditions: less than 30 psi and with chip guarding. The other choices fail because they either set a higher pressure (which increases the risk) or omit the chip guarding requirement, making them noncompliant.
