What type of inspection is triggered by the presence of a thunderstorm?

The type of inspection triggered by the presence of a thunderstorm is classified as a special inspection. Special inspections are conducted in response to specific conditions or events that may affect safety and operational integrity, such as severe weather phenomena like thunderstorms. These inspections focus on assessing any potential hazards or risks related to the storm, ensuring that proper measures are taken to maintain safety for personnel and operations.

The use of special inspections in this context emphasizes the need for a proactive approach to safety during unpredictable and potentially dangerous weather events. In contrast, routine, annual, and visual inspections are scheduled or regular assessments that do not typically respond to immediate environmental conditions as special inspections do.
