What method should be used to force a metal door with no exterior hardware?

Forcing a metal door with no exterior hardware is best accomplished using a method that minimizes damage while efficiently gaining entry. Cutting the door with a circular saw is effective because it allows for precision and control when dealing with the metal material. This technique can create an opening large enough to bypass the locking mechanism without the need for excessive force that might compromise safety or produce additional hazards.

Using a circular saw enables firefighters to cut through any reinforced materials quickly, which is critical in emergency situations where time is essential. Additionally, this method helps avoid the potential injury risks associated with other more forceful techniques, such as kicking the door down or using a battering ram, which could also cause unnecessary damage to both the door and the framework.

Other options, while they may seem viable, either lack the control needed for metal doors or risk causing more harm than necessary. This makes the use of a circular saw the most suitable choice for effectively addressing the situation at hand.
