What is the horsepower of the leaf blower used for clearances?

• A. 0.5 horsepower
• B. 1 horsepower
• C. 2 horsepower
• D. 5 horsepower

Answer: (B)

Clearing gaps and nearby surfaces with a leaf blower requires enough airflow to move dust and debris without creating turbulent gusts that could disturb measurements or damage delicate equipment. A handheld unit around one horsepower strikes the right balance: it provides adequate air volume to effectively clean tight spaces and surfaces, while remaining portable, controllable, and not overly aggressive. A smaller 0.5 hp blower is often not powerful enough to clear debris reliably, whereas larger units (2 hp or 5 hp) generate more noise, weight, and turbulence, which is unnecessary for this task and could interfere with readings or safety.
