What elements should be checked for when equipment falls 3 feet onto a hard surface?

When equipment falls from a height of 3 feet onto a hard surface, it is crucial to conduct a thorough inspection to ensure its safety and functionality. The correct answer encompasses a comprehensive checklist, which includes checking for burs, sharp edges, dirt, contaminants, loose parts, and deformations.

Each of these elements contributes to the overall integrity and reliability of the equipment. Burs and sharp edges can indicate damage that may pose a risk of injury or failure during use. Dirt and contaminants can affect the performance of mechanical components, potentially leading to malfunction or increased wear. Loose parts may suggest structural integrity issues, which could compromise safety during operation. Finally, deformations can indicate that the equipment has sustained significant impact damage, affecting its usability.

In contrast, the other options focus on either insufficient elements for a robust safety check or on aspects that are not as relevant to the operational readiness of the equipment after a fall. Thus, option A is the most appropriate choice for ensuring a thorough safety assessment following an impact.
