The correct answer is that a qualified person is permitted to adjust safety valves. This is rooted in the essential requirement that only individuals who possess the necessary training, knowledge, and skills should undertake adjustments to safety valves. Safety valves are critical components of a boiler system, designed to prevent excess pressure from building up and causing potential hazards. Adjusting these valves improperly can lead to serious safety risks, such as boiler explosions or equipment failure.

A qualified person typically has formal training or certification relevant to boiler operations and safety systems. This ensures that they understand the operational parameters and the specific requirements for the valves in question. While inspectors, chief engineers, and boiler operators may have varying degrees of competence, the emphasis on a "qualified person" underscores the importance of specialized training and experience in carrying out these adjustments safely and effectively.
