Who shall make frequent inspections to ensure sprayer plates and nozzles are in good condition?

The correct choice is the engineering officer because this role encompasses overseeing equipment and systems related to the operation and maintenance of machinery and processes within a facility. An engineering officer is responsible for routine inspections and ensuring that all components, including sprayer plates and nozzles, are functioning properly and in good condition. This role directly involves maintaining operational efficiency and safety standards, which is critical in managing any systems that involve precision equipment like sprayers.

In contrast, while a boiler operator primarily focuses on the operation and maintenance of the boiler systems, the safety officer is more concerned with general safety protocols and ensuring compliance with regulations, rather than specific mechanical inspections. A maintenance technician, although heavily involved in repairs and maintenance, typically follows directives from management and may not always be responsible for conducting regular inspections or overall assessments of operational equipment without guidance from an engineering officer.
