Monitor nozzles shall be inspected how often?

Monitor nozzles shall be inspected how often?

• A. Monthly
• B. Semi-annually
• C. Annually
• D. Quarterly

Answer: (B)

Monitor nozzles are passive spray devices, so they don’t require daily checks but do need periodic inspection to ensure they would discharge correctly if needed. Checking them every six months helps catch issues like blockages, corrosion, paint, or misalignment of the deflector that could impede the intended spray pattern. During the inspection, look for any obstruction around the nozzle opening, signs of corrosion or damage to the nozzle body, paint or debris that could affect flow, and confirm the deflector and mounting hardware are intact and properly oriented. This six-month interval provides a practical balance between catching developing problems and avoiding unnecessary frequent checks, whereas more frequent checks would be excessive for a stationary device, and less frequent checks could allow issues to go unnoticed.
