What should you avoid doing with the roller when using compressed air?

• A. Do not spin the roller with compressed air
• B. Spin the roller rapidly to dry
• C. Spin the roller to clean debris
• D. Do not touch the roller

Answer: (A)

When you blast compressed air at a roller, the air can impart torque and make the roller spin. A rapidly turning roller can grab clothing, hair, or gloves and pull you toward moving parts, which is a serious injury risk. It can also fling debris, lubricant, or surface particles at high speed, potentially striking your eyes or face. Because of these hazards, keep the roller stationary when using compressed air—disconnect power or lock out the machine and direct the air away from the operator, using it to clear debris from surrounding areas rather than trying to spin the roller.
