How often should a boiler be inspected?

The correct frequency for inspecting a boiler is at least annually, or as mandated by local laws and regulations. This requirement is essential because regular inspections help ensure the safe and efficient operation of the boiler, preventing potential hazards such as leaks or malfunctions. Annual inspections provide an opportunity for trained professionals to assess the boiler's condition, identify any necessary repairs, and ensure compliance with safety standards and regulations.

By adhering to these guidelines, boiler operators can mitigate risks that could arise from boiler failures, such as accidents or environmental harm. Additionally, local regulations may impose specific requirements that could differ based on the type of boiler, its location, and its usage, making it crucial for operators to be aware of and comply with these applicable standards.

The other options present either insufficient frequency or specific situations that do not encompass the necessary routine approach to boiler inspections. Inspecting only after major repairs, for example, would not sufficiently address potential issues that could develop over time due to wear and tear.
