If it is not an emergency situation that prompts you to keep the door shut, consider hanging a large and noticeable sign that warns people not to use the door. You might also furnish the room to block access to the door, placing a small table or a bookcase in front of it. A lock can be installed on any door that does not already have one.

The chair barricade and floor wedge techniques work best on a wood or linoleum floor.

In an emergency, it may become necessary to close a door and ensure it does not come open until the emergency passes. In most cases, you can rely on a lock, but sometimes a normal lock is not sufficient. There are other steps you can take to prevent a door from opening in the case of an emergency. Knowing how to properly barricade a door with everyday household objects can protect you and your family.


Step 1

Jam a wooden or metal chair under the doorknob. The chair will lean back with its front feet in the air. Jam the back legs of the chair back as far as you can to ensure the chair will not move.

Step 2

Hammer wooden or rubber wedges under the door. Hammer some into the area around the doorknob as well. Hammer them down until they can go no further.

Step 3

Move a large and heavy piece of furniture in front of the door. As with steps 1 and 2, this technique works if the door opens inward, towards you. Place the piece of furniture as close to the opening of the door as you can. Most people try to block the whole door, but right below the doorknob is the area that really counts.


Step 4

Tie a rope or cord around the doorknob you want to keep shut. Tie the other end of the rope to another doorknob in the room. This will only work if the door you are trying to keep shut opens away from you. Tying this rope from one doorknob to the other gives the door an anchor. You can also anchor the door to another stable structure like a beam.
