Short answer. Yes. Rule 113, Section 12 allows an officer who has entered a building or enclosure under the preceding section — the rule permitting forced entry to make an arrest — to break out of it when necessary to liberate himself. The right to break out mirrors the right to break in.
What the law says
Whenever an officer has entered the building or enclosure in accordance with the preceding section, he may break out therefrom when necessary to liberate himself.

A narrow, follow-on right
Section 12 does not stand alone — it operates only where the officer entered under the preceding section, which allows forced entry into a building or enclosure to make a lawful arrest. Given that lawful entry, Section 12 addresses what happens if the officer then becomes trapped inside and needs to get out. The preceding section allows an officer to break open a door or window of a building where a person to be arrested is reasonably believed to be, after giving notice and being refused admittance, and Section 12 picks up from exactly that point. This follow-on right binds only the officer whose original entry was itself lawful under the preceding section; it says nothing about an officer who entered unlawfully in the first place, whose position on breaking back out is not addressed by this provision at all.
Necessity is the limiting condition
The rule ties the right to break out to necessity — it applies when breaking out is necessary to liberate the officer, not as a general license to damage property on the way out. The provision exists because an officer who lawfully forced entry should not be left with no lawful way to leave. It is not a license to cause unnecessary damage on the way out beyond what liberating the officer actually requires, so an officer who could exit through an unlocked door instead cannot simply break a wall for convenience.
Why the rule mirrors forced entry
The logic is symmetrical: the same emergency reasoning that lets an officer break into a building to complete a lawful arrest lets him break back out if he becomes confined there. It closes an obvious gap that would otherwise leave an officer legally entitled to enter, but with no clear legal authority to leave. Without Section 12, an officer could be left lawfully inside a structure with no clear authority to force a way back out again. The two provisions read together as a single continuous authority covering both the entry and the exit tied to the same lawful arrest.
