Security rules at the escalator at the Capitol building’s Capitol Visitors Center have been tightened to prevent a cascade of falls on the escalators.

The new rules include safety features such as an emergency exit, metal bars on the ends of the escalating platforms and a railing that stops falling, according to Metro officials.

The new rules are meant to ensure people and items inside the escalations do not fall.

They are meant for security reasons, not for entertainment purposes, according Metro spokesman Tom Stessel.

The escalators are equipped with cameras and alarms, and Metro will install an emergency camera that will alert people when they have entered an escalator and are about to go down.

If an escalators malfunctiones, the camera will send an alert to Metro and the escalates operator.

Security guards will be on hand to assist people when it comes to their safety.
