Certified Playground Safety Inspector (CPSI) Practice Exam 2025 – All-in-One Guide to Exam Success

The minimum insertion depth for a partially bound opening probe is indeed 3/4 inches (0.75). This measurement is crucial for assessing the safety of playground equipment, particularly in ensuring that children cannot become entrapped in openings that are deemed to be hazardous.

Partially bound openings are those where one section is restricted, and the probe's depth measurement is designed to simulate the size of a child's body part, such as their head or torso. The standard depth of 3/4 inches is established in the guidelines for evaluating playground equipment to prevent entrapment injuries. By using a probe with this specific insertion depth, inspectors can verify that openings are safe for children to use, ensuring that they mitigate the risk of injury while playing on the equipment.

This standard is set to protect children from potential accidents and ensure that the equipment complies with safety regulations. Understanding these measurements is key for playground safety inspectors as they conduct thorough evaluations of play environments.
