Defense Preparedness

POWER OUTAGE PREPAREDNESS:

Before a power outage occurs it is import to take steps now to prepare: Have an emergency charging option for your phone and other mobile devices. Smartphones have become a vital tool to receive emergency alerts and warnings, so it’s important to make sure you can keep them powered up in an emergency. Prior to severe weather, make sure that all of your electronic devices are fully charged. If the power goes out, preserve battery power by minimizing device use. Keep a back-up power source on hand to recharge your phone so that you can stay connected even during an extended power outage. Keep a portable phone charger in your vehicle at all times, and consider purchasing a back-up power supply to keep in your vehicle as well.

Consider setting up an emergency solar and/or wind powered power generation system to power appliances and store in batteries. If you are considering purchasing a generator for your home, consult an electrician or engineer before purchasing and installing. Only use generators away from your home and NEVER run a generator inside a home or garage, or connect it to your home's electrical system.

Battery-stored backup power - Allows you to continue operating lights, refrigerators and other appliances, fans, and communications during a power outage. These systems can connect to renewable sources of energy, like solar panels and small-scale wind generators, to help the batteries stay charged during an emergency. You can also recharge many of these battery systems with diesel generators. The length of time you will be able to draw electricity from your batteries will depend on the size of your battery bank. Emergency mobile battery backup power systems can power cell phones and lights for a relatively short period of time (for example, 700−1,500 watt hours). Pre-wired solar-powered battery backup systems offer more power output for longer periods of time (example, 5,000−10,000 watt hours).

Solar power - Solar power can provide a portion of daily primary power as well as reliable backup power during an emergency. Solar panels, or solar modules, are typically installed on the roofs of homes or work facilities. These solar panels are made up of photovoltaic cells, which convert sunlight into direct current power, which is then converted by an inverter into alternating current power, or standard electrical current used in your home or office. Battery systems can recharge using solar power. As the solar panels generate energy during the day, any excess energy not used by the home or office can be stored for use at night, on rainy days, or during power outages.

 Wind power—A small-scale wind electric system (such as residential or institutional) can help homeowners, small business owners, and public facilities generate their own energy for onsite use. A small wind turbine produces electricity from wind when moving air causes the turbine to rotate. Most small wind turbines look like a miniaturized version of the large, utility-scale, three-bladed turbines, but other models can vary widely in appearance. Wind electric systems are less widely used by the public than solar-powered systems because many municipalities do not include small wind systems in local zoning codes. This often makes permitting and installing the systems difficult and costly.

 Fuel cells - Fuel cells are similar to batteries and can power cars, trucks, and buses, as well as portable devices such as cell phones and laptop computers. Fuel cell systems can also provide backup power to buildings and facilities. Today, fuel cells are often fueled with natural gas. They are relatively expensive. In 2005, the most widely deployed fuel cells cost about $4,500 per kW; by contrast, a diesel generator costs $800 to $1,500 per kW.

Store important documents in a secure, password-protected jump drive or in the cloud and have paper copies. Back-up your computer to protect photos and other personally important electronic documents. Scan old photos to protect them from loss.

Keep your contacts updated and synced across all of your channels, including phone, email and social media. This will make it easy to reach out to the right people quickly to get information and supply updates. Consider creating a group listserv of your top contacts.

Build or restock your emergency preparedness kit , including a flashlight, batteries, cash, and first aid supplies.

Know where the manual release lever of electric garage door opener is located and how to operate it.

Freeze water-filled reusable containers to help keep food cold during a temporary power outage.

Keep your car’s gas tank full-gas stations rely on electricity to power their pumps. If you use your car to re-charge devices, do NOT keep the car running in a garage, partially enclosed space, or close to a home, this can lead to carbon monoxide poisoning.

Learn about the emergency plans that have been established in your area by visiting your state’s or local website so you can locate the closest cooling and warming shelters.

If you rely on anything that is battery-operated or power dependent like a medical device, determine a back-up plan and consider investing in redundant power systems like back-up solar generators and batteries.

During a Power Outage: Safety Tips:
Keep refrigerator and freezer doors closed. Most food requiring refrigeration can be kept safely in a closed refrigerator for several hours. An unopened refrigerator will keep food cold for about 4 hours. A full freezer will keep the temperature for about 48 hours. For more information about food safety visit our food page.

Take steps to remain cool if it is hot outside. In intense heat when the power may be off for a long time, consider going to a movie theater, shopping mall or “cooling shelter” that may be open in your community. If you remain at home, move to the lowest level of your home, since cool air falls. Wear lightweight, light-colored clothing. Drink plenty of water, even if you do not feel thirsty.

Put on layers of warm clothing if it is cold outside. Never burn charcoal for heating or cooking indoors. Never use your oven as a source of heat. If the power may be out for a prolonged period, plan to go to another location (the home of a relative or friend, or a public facility) that has heat to keep warm.

Turn off or disconnect appliances and other equipment in case of a momentary power “surge” that can damage computers and other devices. Consider adding surge protectors.

After a Power Outage:
Throw away any food that has been exposed to temperatures 40° F (4° C) for 2 hours or more or that has an unusual odor, color or texture. When in doubt, throw it out!

If food in the freezer is colder than 40° F and has ice crystals on it, you can refreeze it.

Contact your doctor if you’re concerned about medications having spoiled.

Restock your emergency kit with fresh batteries, canned foods and other supplies

SHELTER:

To effectively shelter, you must first consider the hazard and then choose a place in your home or other building that is safe for that hazard. For example, for a tornado, a room should be selected that is in a basement or an interior room on the lowest level away from corners, windows, doors and outside walls. The safest locations to seek shelter vary by hazard. Be Informed about the sheltering suggestions for each hazard. There may be situations, depending on your circumstances and the nature of the disaster, when it's simply best to stay where you are and avoid any uncertainty outside by “sheltering in place".

The length of time you are required to shelter may be short, such as during a tornado warning, or long, such as during a winter storm or a pandemic. It is important that you stay in shelter until local authorities say it is safe to leave. Additionally, you should take turns listening to radio broadcasts and maintain a 24-hour safety watch. During extended periods of sheltering, you will need to manage water and food supplies to ensure you and your family have the required supplies and quantities.

Mass Care Shelters:
Even though mass care shelters often provide water, food, medicine and basic sanitary facilities, you should plan to take your disaster supplies kit with you so you will have the supplies you require. Mass care sheltering can involve living with many people in a confined space, which can be difficult and unpleasant. To avoid conflicts in the stressful situation, it is important to cooperate with shelter managers and others assisting them. Keep in mind that alcoholic beverages and weapons are forbidden in emergency shelters and smoking is restricted. Search for open shelters by texting SHELTER and a Zip Code to 43362 (4FEMA).

Guidelines for Staying Put (Sheltering in Place):
Whether you are at home, work or elsewhere, there may be situations when it's simply best to stay where you are and avoid any uncertainty outside.

There may be circumstances when staying put and creating a barrier between yourself and potentially contaminated air outside, a process known as "sealing the room," is a matter of survival. Use common sense and available information to assess the situation and determine if there is immediate danger. 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.

The process used to seal the room is considered a temporary protective measure to create a barrier between you and potentially contaminated air outside. It is a type of sheltering in place that requires preplanning.
 -Bring your family and pets inside.
 -Lock doors, close windows, air vents and fireplace dampers.
 -Turn off fans, air conditioning and forced air heating systems.
 -Take your emergency supply kit unless you have reason to believe
it has been contaminated.
 -Go into an interior room with few windows, if possible.
 -Seal all windows, doors and air vents with 2-4 mil. thick plastic
sheeting and duct tape. Consider measuring and cutting the
sheeting in advance to save time.
 -Cut the plastic sheeting several inches wider than the openings
and label each sheet.
 -Duct tape plastic at corners first and then tape down all edges.
 -Be prepared to improvise and use what you have on hand to seal
gaps so that you create a barrier between yourself and any
contamination.

Local authorities may not immediately be able to provide information on what is happening and what you should do. However, you should watch TV, listen to the radio or check the Internet often for official news and instructions as they become available.

Wilderness Sheltering:
If you are caught outside or in the wilderness and need to take shelter, make a sign around you that can alert search and rescue to your location, preferably visible by air.

The three best ways to create an ad-hoc wilderness shelter is tarp shelter, wickiup, and a leaf lean-to hut.
 -A wikiup is essentially a “teepee” style shelter made with forest
debris. There are other less time-consuming primitive shelters that
you can make in a pinch. However, in a longer term survival
scenario in colder weather, the wikiup is king for an important
reason: it allows the use of a fire inside the shelter. Note that no
tools are need to make this survival shelter.

1. Prep the Space - Start by clearing the forest floor where the wikiup will be built.
2. Make a Tripod – Using 3 sturdy branches, make a tripod with your main support poles. You may choose to secure these poles together with a tripod lashing, although it is not necessary. I like to use poles with a “Y” shape on one end so that they can be locked together and spread apart at the bottoms to make the basic tripod for the survival shelter.
3. Add More Poles - Once the tripod is in place, continue to place straight poles around the circumference of the shelter. Place the poles as close to one another as you feel necessary, but don’t worry about closing all the gaps.
4. Add Insulation - The next objective is to get insulation/shingles installed. For that you will be using forest debris. This is no different than putting shingles on a house. Start at the bottom and work your way up. The same is true with any primitive shelter. This allows the survival shelter to properly shred rain. Continue to pile leaves, pine needles and any other debris in the area to the wikiup. The more insulation added, the more dead air space that can be trapped and ultimately the warmer the inside of the shelter will become.

***A wikiup shelter is at least a five- to six-hour project, even taking up an entire day, and requires regular resupply of leaves. Remember to gather debris farther away from the build site and work your way in for less traveling in the later stages.
