Step-by-step explanation:
In construction, a competent person must inspect excavations regularly to ensure safety and compliance with regulations. The frequency of inspections depends on the specific circumstances, but typically, inspections should be done at least daily before workers enter the excavation and after any occurrence that could affect its stability. Ongoing inspections should be conducted whenever conditions change, such as after rainstorms or if new equipment is brought in. Inspections are crucial to identify hazards and take appropriate measures to prevent accidents.
