Closing interior doors before a tornado or hurricane can reduce the pressure on your roof by up to 30 degrees, helping it stay intact. It is also recommended to close exterior doors during a tornado for added safety. The safest place in a home is the interior part of a basement, or an inside room without windows on the lowest floor.
During a tornado warning, go to your basement, safe room, or an interior room away from windows. Remember to remember pets if time allows. At workplaces or schools, follow your tornado drill and follow the instructions.
Opening windows during a tornado is a bad idea as it allows damaging winds to enter the structure. Instead, leave the building and go to the interior hall or windowless room in an orderly manner. Crouch low, head down, and protect your back with your arms. Stay away from windows and large open rooms like gyms.
In buildings, keep exterior doors and windows closed to minimize rain and flying debris. Closing interior doors will also help compartmentalize the building and provide more barriers between employees and the storm. Opening windows during a tornado will only let in violent wind and debris that could hit you and kill you.
In schools, hospitals, factories, and shopping areas, opening windows will only weaken your home as strong winds gust around inside. The best thing to do during a tornado is to stay indoors and close all windows and doors. In a major windstorm, shut all internal doors and windows.

When taking shelter from a tornado, should you have at least one or two windows open to release pressure inside your home?
📹 Open Your Windows During Tornado?
For years the advice has been if you are in the path of a tornado, you should open your windows, but is this true? See more on …
Not only does opening windows not make any difference as to what happens to the house (an EF2 or higher tornado will open them all with flying debris anyway), you also end up wasting precious time that could be more effectively used seeking shelter in order to survive the storm. Houses can be rebuilt, human lives are irreplaceable.
I would test with a standard home, one story with an attic (Maybe) and having a way from the pressure be relieved though another opening. The advice is you open your windowS and doorS, but with only one opening its no wonder the house is torn asunder. Maybe having multiple openings reduces the air pressure and reduces structure damage. After all, a sail with a hole will still sail as long as the air pressure in the sail can overcome the opening.
Wont matter, opening windows will most likely make it worse. The sheer uplifting force of a tornado will just pop your roof right off. Closed windows wont matter either, just run to a safe place. The problem is the fact that there is no equalizing of the pressure inside a house with the outside pressure of a tornado. A tornado is simply so strong it wont matter. If anything matters is not building your house out of matchsticks like to many Americans seem to do. Go with reinforced concrete walls and a solid roof. Might still get damaged mind you, from debris if nothing else and unless we’re talking f4 or 5 class tornado here, it will most likely survive relatively intact.
Several things make this a ridiculous and invalid test. First, it’s painfully obvious that the house on the right was not subjected to nearly as much wind force (just look at the plants hanging on the porch, they are barely even moving while the left house has its siding all ripped up even before it took the house). Thus, all things being equal, both front doors should have blown open. Clearly not equal winds given to both houses. Second, opening just the front door is not sufficient to test the hypothesis. The idea is that with ALL the windows open, air can freely move through the house and out the other side. Just opening the door provides a path of least resistance for all the wind to enter, but nowhere for it to go once inside, therefore it pushes the house in the direction of the wind. So not only is your experiment flawed, you literally didn’t even test your hypothesis … Third, a hypothesis like this requires several repeated experiments. There are simply too many variables: wind speed, house size, house material (brick? wood? plaster? sheetrock?), window quality (single pane? double pane? tempered glass?), number of windows, direction of tornado, size of tornado, surrounding environments, etc. You can’t just blow some wind at a house and claim the myth is busted lol. However, having said all that, it is in fact a myth 🙂 Just not according to this experiment …
Institute for Business and Home Safety, the article here is cut to identify you as the Institute for Business and Home Safety. Yet I am of a mind that you are actually the Insurance Institute for Business and Home Safety.-Ernie Moore Jr. The claim is the Insurance Institute for Business and Home Safety is a Non-Profit; however I wondered if it is less costly for Insurance to pay for a new house than to fix a partially damaged house given the quality of construction for the areas that tend to get struck or some such some might say.-Ernie Moore Jr.
These houses are not built to scale… a real house has interior walls, which change how the wind reacts inside the building… not to mention are secured to the same floor as the exterior walls, which are also secured to the roof with a ceiling… all of these things ties everything together to make the structure WAY heavier and WAY more stable than these hollow models 🤔 When the house is blown away, there is zero evidence that the building had anything more than four exterior walls… holding up the roof, but maybe no ceiling 😔 As structurally similar as an empty cardboard box to a full one. Also, the theory is to open more than one window or door… The wind needs a place to go to relieve the pressure on the facing wall. This demonstration was useless
