Tornado Safety Tips
Tornado Safety Tips
The University receives its tornado watches and warnings from the local television and radio stations. Jefferson City's warning sirens can be heard throughout campus. If the sirens are activated, students and employees should take immediate shelter in basements or move to interior hallways away from windows. Public Safety officers do not go from building to building giving instructions or coordinating evacuations to safe areas. You must heed the warning independently and move to a safe area on your own. The Jefferson City all clear sirens will alert you when it is safe to return.
Up to date weather information can be obtained at the following locations:
Tornadoes are nature's most violent - and erratic - storms. A tornado can travel for miles along the ground, lift and suddenly change direction and strike again. There is little you can do to protect your home or workplace from the strength of tornado winds, but there are actions you can take to protect yourself and your family better.
Basic Safety Rules:
- Keep alert to changing weather conditions.
- Take shelter immediately where you hear a tornado warning or see a funnel cloud.
- Know where your shelter is before you need it.
Tornadoes are formed by severe thunderstorms, most frequently in the spring and summer. If you live in a tornado-prone area, stay alert during severe weather.
Know your community's warning signals. Most often warnings will be given by local radio and television stations and by NOAA Weather Radio. In addition, some communities have sirens or whistles to warn of natural disasters.
Watches and Warnings
A TORNADO WATCH is given when weather conditions are favorable to the formation of tornadoes, for example during severe thunderstorms. During a TORNADO WATCH, keep an eye on the weather and be prepared to take shelter immediately if conditions worsen.
A TORNADO WARNING is given when a tornado funnel is sighted or indicated by radar. You should take shelter immediately. Because tornadoes can form and move quickly, there may not be time for a warning. That's why it's important to stay alert during severe storms.
Although there is no guaranteed safe place during a tornado, some locations are better than others. By following these suggested safety tips, you can increase your chances for survival.
What to Do if You are In a Residence Hall?
Residents must proceed to the basement of those residence halls that have one, or the hallways on the 1st floor of residence halls without a basement. Most, if not all hall lounges have windows. Know what your residence hall severe weather plan is ahead of time. Follow the instructions of hall personnel and don't leave the building until the all clear is given.
What to Do if You are In Class?
When the storm warning sirens sound, it is best Not to leave the building. Obviously, it is better to seek shelter in a basement. If the building you are in has no basement, or there is no building nearby with a basement, go to the lowest floor and get into a small interior room or hallway. Stay away from glass and exterior walls; put as many walls between you and the storm as you can.
Get to shelter immediately. AVOID WINDOWS. Flying glass can injure or kill. Don't open windows. Houses don't "explode" and allowing strong wind in can do damage or cause injury. The safest place in the home is the interior part of the basement, preferably under something sturdy like a table. Stay out from under heavy objects like pianos or refrigerators in the floor above. If you have no basement, go to an inside room on the lowest floor, like a closet, hallway, or bathroom with no windows. For added protection, get under something strong, like a workbench or heavy table. If possible, cover your body with a blanket or sleeping bag and protect your head with anything available, even your hands.
Do not stay in a mobile home during a tornado. Even homes with a secure tie down system cannot withstand the force of tornado winds. Plan ahead. Make arrangements to stay with friends or neighbors who have a basements. Go there if a tornado watch is issued. If a tornado warning is given, leave your mobile home and seek shelter nearby. Lie flat in a ditch or ravine and put your arms over your head. Don't take shelter under your home. Encourage your mobile home community to build a tornado shelter if you live in a tornado-prone area.
The least desirable place to be during a tornado is in a motor vehicle. Cars, buses, and trucks are tossed easily by tornado winds. Do not try to outrun a tornado in your car.
If you see a tornado, stop your vehicle and get out. Seek shelter away from the car in a nearby ditch or ravine. Don't take shelter under your vehicle. Lie flat in a ditch or ravine and put your arms over your head.
Long span buildings are dangerous. The entire roof structure is supported solely by the outside walls. Inside walls are usually false or non-load bearing walls.
If you are caught in a open building like a shopping mall, civic center, indoor pool, theater, or gymnasium during a tornado, stay away for windows. Get into the restroom, if possible. In larger buildings the restrooms are usually made from concrete block. Besides having four walls and plumbing holding things together, metal partitions help support any falling debris. If there is not time to go anywhere, seek shelter right where you are. Try to get up against something that will support or deflect falling debris. For instance, in a department store, get up against heavy shelving or counters. In a theater, get under seats. Remember to protect your head.
Extra precautions are needed in these structures. Not only is there a large concentration of people in a small area, but these buildings usually have large amounts of glass on the outside walls. Get into the innermost portions on the lowest floor possible. Avoid windows, glass doorways, and auditoriums and cafeterias not protected by overhead floors and rooms. Do not use elevators; the power may go off and you could become trapped. Protect your head and make yourself a small target as possible by couching down.
If you are caught outside during a tornado and there is no underground shelter immediately available, lie in a gully ditch, or low spot in the ground. Protect your body and head with anything available. Do not go into a grove of trees or under a vehicle.
Emergency services personnel are usually on the scene quickly after a tornado. Keep your family together and wait for help to arrive. Listen to the radio for information about disaster relief and volunteer agencies.
If you are outside, don't go into damaged buildings; they may collapse completely. Wait for help to search for others. If your home appears undamaged, check carefully for gas or other utility line breaks. If the lights are out, use a flashlight only; do not use a match, lighter, or any open flame.
