Which feature is prohibited in new manholes?

Explanation:
Access into a manhole must have a safe, continuous means of ascent and descent. Built-in steps in the wall do not provide reliable handholds and can be slippery, trap debris, or snag clothing, making entry, exit, and rescue risky. Modern practice requires a fixed ladder with proper rungs and handholds, so steps are prohibited in new manholes. Grates and seals serve other purposes—ventilation and sealing against gases or water—and do not replace the safe access device required for entry, which is why they’re not the standard for new installations.
