Technology and experience have provided many tools to help make forecasting natural disasters more accurate. Satellites, radar and historical data all contribute to increased accuracy and more reliable forecasts. While forecasting is fairly accurate at predicting what may happen, it isn't an exact science. Occasionally, the actual event is less severe than the forecast; other times, it can be much worse.
Unfortunately, natural disasters are no longer the only type of emergency or disaster we may experience. Influences from political, economic or religious views can contribute to unpredictable man-made events that are nearly impossible to predict. The result can be very similar to those created by nature. One significant difference is that man-made disasters are typically unexpected.
No matter what type of emergency or disaster occurs, an emergency preparedness plan can make a difference between life and death. While there are federal, state and local police and fire department resources set up to provide assistance, personal preparedness is also essential.
While no one can fully anticipate what kinds of emergencies or disasters may occur, an emergency preparedness plan can make a difference in the days that follow. Collecting supplies and planning and preparing for your personal needs are best done before warnings are issued or after something happens. This way, there is no rush and supplies are plentiful.
With any disaster or emergency, there are basic survival needs to consider. At a minimum, water, food and shelter are absolute necessities. Depending on the nature of the event, clean, breathable air and additional supplies may also be needed. Keep everything in a container or some other device that provides protection, portability and ease of access.
For drinking and sanitation, plan on having at least one gallon of potable water per person per day for at least three days:
Containers for Water Storage
Food-grade plastic or glass containers are suitable for storing water. Any plastic or glass container that previously held food or beverages—such as soda bottles, or water, juice, punch or milk jugs—may be used. Stainless steel containers can be used to store water that has not been or will not be treated with household bleach.
Use hot soapy water to thoroughly clean used containers and lids. Then rinse them with water and sanitize them by rinsing with a solution of four teaspoons of household bleach per gallon of water. Leave the containers wet for two minutes and then rinse again with water. Remember to remove the paper or plastic lid liners before washing the lids. It is very difficult to effectively remove all residues from many containers, so carefully clean hard-to-reach places like the handles of milk jugs. To sanitize stainless steel containers, place the container in boiling water for 10 minutes. Never use containers that previously held chemicals of any kind.
Once you properly clean containers, fill them with potable drinking water. All public water supplies are already treated and should be free of harmful bacteria. However, as an additional precaution, it is suggested that you add 1/8 teaspoon of standard household bleach per gallon of clear tap water stored to help protect against any lingering organisms in storage containers that may have been inadvertently missed during the cleaning process.
Clearly label all drinking water containers with the current date. Store the water in a cool, dry place away from direct sunlight and heat sources. Do not store it near gasoline, kerosene, pesticides or any hazardous substance.
Properly stored potable water should have an indefinite shelf life; however, it's a good idea to use and replace the stored water every 6 to 12 months. If you have freezer space, storing some water in the freezer is a good idea. If you lose electricity, the frozen water will help keep foods in your freezer frozen until the power is restored. Make sure you leave 2 to 3 inches of space in containers because water expands as it freezes.
In an emergency, if you have not previously stored water and commercial or public sources of water are unavailable, drain water from your plumbing system. Unless you are advised that the public water supply has been contaminated and is not safe, open the drain valve at the bottom of the water heater and salvage the water stored in the heater. A typical water heater holds 30 to 60 gallons of water. Discard the first few gallons if they contain rust or sediment. Let the water heater cool before draining water from the heater to avoid being scalded. Turn off the electricity or gas to the water heater to prevent the heater from operating without water. Once water has been drained into clean, sanitized containers, add 1/8 teaspoon of plain, unscented standard household bleach per gallon of water, and stir or shake the solution to mix it. Let it set 30 minutes before use.
In an emergency, if you do not have water that you know is safe, it’s possible to purify water for drinking. Start with the cleanest water you can find and then purify it by boiling. Times may vary from state to state, depending on altitude. If you plan to store the boiled water, pour it into clean, sanitized containers and let it cool to room temperature. Then add 1/8 teaspoon of standard household bleach per gallon of water. Stir or shake the solution to mix it. Cap the containers and store them in a cool, dry place.
Contact your public health and environment agency for advice on treatment and storage of well water.
Collect at least a three-day supply of nonperishable food.
In any emergency, a family member or you yourself might sustain cuts, burns or other injuries. Keep basic first aid supplies on hand. Remember, many injuries are not life threatening and may not require immediate medical attention. Knowing how to treat minor injuries can make a difference in an emergency. Consider taking a first aid class, but simply having the following things can help you stop bleeding, prevent infection and assist in decontamination.
Things it may be good to have:
Many people think shelter is the same as their home. It's important to realize that what you consider to be shelter may not always be in or near where you live. Where you live may be in the area that is at risk, and shelter can only be found by evacuation to another location.
Federal, state or local agencies will typically broadcast directions on what to do or where to go. News broadcasts on TV or radio may also give directions. Instructions could be to seek shelter in a room within your home or to evacuate to another area.
Staying where you are is often the best thing to do. You may be given instructions to move to an interior room, away from doors and windows.
There are circumstances when you need to create a barrier between yourself and potentially contaminated air outside. This is a process known as sealing the room and is a matter of survival. Use available information to assess the situation. If you see large amounts of debris in the air, or if local authorities say the air is badly contaminated, you may want to take this kind of action.
To shelter in place and seal the room:
If there is damage to your home or you are instructed to turn off your utilities:
There may be conditions under which you decide to get away, or there may be situations when you are ordered to leave. Ensure your emergency preparedness plan outlines how you will assemble your family and anticipate where you will go. Choose several destinations in different directions so you have options in an emergency.
In general, it is best to evacuate at right angles to the direction of the threat. For example, if a storm is approaching from the west, it is best to evacuate toward the north or south.
Create an evacuation plan:
If time allows:
There are many possibilities or combinations of contaminants that can pollute the air. Some examples are vapors, dusts, smoke and airborne organisms like mold and viruses.
Respirators are devices worn to protect against the inhalation of contaminants. A respirator can be something as simple as a handkerchief tightly fitted across the nose and mouth. Some are single use and disposable, while others allow you to customize the protection by using replaceable, disposable cartridges that filter, scrub or absorb contaminants from the air.
Unfortunately, there is no one device that can remove all the possible air contaminants. The best filter for particulate contaminants is a P100 filter, which is oil proof and removes 99.97% of particles down to 0.3 microns. A chemical, biological, radiological and nuclear (CBRN) respirator adds a broad spectrum of chemical protection beyond a particulate-only-filter. While a self-contained breathing apparatus (SCBA) contains its own air supply, it is not practical for use longer than 30 to 60 minutes.
