Emergency Threats

Chemical Threat

A chemical attack is the deliberate release of a toxic gas, liquid or solid that can poison people and the environment.

  • Many people suffering from watery eyes, twitching, choking, having trouble breathing or losing coordination. 
  • Many sick or dead birds, fish or small animals are also cause for suspicion.
  • Find Clean Air Quickly
  • Quickly try to define the impacted area or where the chemical is coming from, if possible.
  • Take immediate action to get away. 
  • If the chemical is inside a building where you are, get out of the building without passing through the contaminated area, if possible. 
  • If you can’t get out of the building or find clean air without passing through the area where you see signs of a chemical attack, it may be better to move as far away as possible and shelter-in-place.. 
  • If you are outside, quickly decide what is the fastest way to find clean air. Consider if you can get out of the area or if you should go inside the closest building and “shelter-in-place.”
    • If you think you may have been exposed to a chemical, strip immediately and wash. 
    • Look for a hose, fountain, or any source of water, and wash with soap if possible, being sure not to scrub the chemical into your skin. 
    • Seek emergency medical attention.

Explosions

  • Take shelter against your desk or a sturdy table. 
  • Exit the building ASAP. 
  • Do not use elevators. 
  • Check for fire and other hazards. 
  • Take your emergency supply kit if time allows.
  • Exit the building ASAP. 
  • Crawl low if there is smoke 
  • Use a wet cloth, if possible, to cover your nose and mouth. 
  • Use the back of your hand to feel the upper, lower, and middle parts of closed doors. 
  • If the door is not hot, brace yourself against it and open slowly. 
  • If the door is hot, do not open it. Look for another way out. 
  • Do not use elevators 
  • If you catch fire, do not run. Stop-drop-and-roll to put out the fire. 
  • If you are at home, go to a previously designated meeting place. 
  • Account for your family members and carefully supervise small children. 
  • Never go back into a burning building.
    • If possible, use a flashlight to signal your location to rescuers.
    • Avoid unnecessary movement so that you don’t kick up dust. 
    • Cover your nose and mouth with anything you have on hand. (Dense-weave cotton material can act as a good filter. Try to breathe through the material.) 
    • Tap on a pipe or wall so that rescuers can hear where you are. 
    • If possible, use a whistle to signal rescuers. 
    • Shout only as a last resort. Shouting can cause a person to inhale dangerous amounts of dust.

Biological Threat

A biological attack is the deliberate release of germs or other biological substances that can make you sick. Many agents must be inhaled, enter through a cut in the skin or be eaten to make you sick. Some biological agents, such as anthrax, do not cause contagious diseases. Others, like the smallpox virus, can result in diseases you can catch from other people.

  • Unlike an explosion, a biological attack may or may not be immediately obvious. While it is possible that you will see signs of a biological attack, as was sometimes the case with the anthrax mailings, it is perhaps more likely that local health care workers will report a pattern of unusual illness or there will be a wave of sick people seeking emergency medical attention. You will probably learn of the danger through an emergency radio or TV broadcast, or some other signal used in your community. You might get a telephone call or emergency response workers may come to your door. In the event of a biological attack, public health officials may not immediately be able to provide information on what you should do. It will take time to determine exactly what the illness is, how it should be treated, and who is in danger.
  • Are you in the group or area authorities consider in danger? 
  • What are the signs and symptoms of the disease? 
  • Are medications or vaccines being distributed? 
  • Where? Who should get them? 
  • Where should you seek emergency medical care if you become sick?
  • If a family member becomes sick, it is important to be suspicious. 
  • Do not assume, however, that you should go to a hospital emergency room or that any illness is the result of the biological attack. Symptoms of many common illnesses may overlap. 
  • Use common sense, practice good hygiene and cleanliness to avoid spreading germs, and seek medical advice. 
  • Consider if you are in the group or area authorities believe to be in danger. 
  • If your symptoms match those described and you are in the group considered at risk, immediately seek emergency medical attention.
  • Follow instructions of doctors and other public health officials. 
  • If the disease is contagious expect to receive medical evaluation and treatment. You may be advised to stay away from others or even deliberately quarantined. 
  • For non-contagious diseases, expect to receive medical evaluation and treatment.
  • Quickly get away. 
  • Protect yourself. Cover your mouth and nose with layers of fabric that can filter the air but still allow breathing. Examples include two to three layers of cotton such as a t-shirt, handkerchief or towel. Otherwise, several layers of tissue or paper towels may help. 
  • Wash with soap and water. 
  • Contact authorities. 
  • Watch TV, listen to the radio, or check the Internet for official news and information including what the signs and symptoms of the disease are, if medications or vaccinations are being distributed and where you should seek medical attention if you become sick.
  • If you become sick seek emergency medical attention.

Winter Weather

While the danger from winter weather varies across the country, nearly all Americans, regardless of where they live, are likely to face some type of severe winter weather at some point in their lives. That could mean snow or subfreezing temperatures, as well as strong winds or even ice or heavy rain storms. One of the primary concerns is the winter weather’s ability to knock out heat, power and communications services to your home or office, sometimes for days at a time. The National Weather Service refers to winter storms as the “Deceptive Killers” because most deaths are indirectly related to the storm. Instead, people die in traffic accidents on icy roads and of hypothermia from prolonged exposure to cold. It is important to be prepared for winter weather before it strikes.

  • Get an Emergency Supply Kit which includes items like non-perishable food, water, a battery-powered or hand-crank radio, extra flashlights and batteries.
  • Thoroughly check and update your family’s Emergency Supply Kit before winter approaches and add the following supplies in preparation for winter weather:
    • Rock salt to melt ice on walkways
    • Sand to improve traction
    • Snow shovels and other snow removal equipment.
    • Also include adequate clothing and blankets to keep you warm
  • Make a Family Emergency Plan. Your family may not be together when disaster strikes, so it is important to know how you will contact one another, how you will get back together and what you will do in case of an emergency.
  • Plan places where your family will meet, both within and outside of your immediate neighborhood.
  • It may be easier to make a long-distance phone call than to call across town, so an out-of-town contact may be in a better position to communicate among separated family members.
  • You may also want to inquire about emergency plans at places where your family spends time: work, daycare and school. If no plans exist, consider volunteering to help create one.
  • Take a Community Emergency Response Team (CERT) class from your local Citizen Corps chapter. Keep your training current.
  • Make sure your home is well insulated and that you have weather stripping around your doors and windowsills to keep the warm air inside.
  • Insulate pipes with insulation or newspapers and plastic and allow faucets to drip a little during cold weather to avoid freezing.
  • Learn how to shut off water valves (in case a pipe bursts).
  • Keep fire extinguishers on hand, and make sure everyone in your house knows how to use them. House fires pose an additional risk as more people turn to alternate heating sources without taking the necessary safety precautions.
  • Know ahead of time what you should do to help elderly or disabled friends, neighbors or employees.
  • Hire a contractor to check the structural stability of the roof to sustain unusually heavy weight from the accumulation of snow – or water, if drains on flat roofs do not work.
  • If you have a car, fill the gas tank in case you have to leave. In addition, check or have a mechanic check the following items on your car:
    • Antifreeze levels – ensure they are sufficient to avoid freezing.
    • Battery and ignition system – should be in top condition and battery terminals should be clean.
    • Brakes – check for wear and fluid levels.
    • Exhaust system – check for leaks and crimped pipes and repair or replace as necessary. Carbon monoxide is deadly and usually gives no warning.
    • Fuel and air filters – replace and keep water out of the system by using additives and maintaining a full tank of gas.
    • Heater and defroster – ensure they work properly.
    • Lights and flashing hazard lights – check for serviceability.
    • Oil – check for level and weight. Heavier oils congeal more at low temperatures and do not lubricate as well.
    • Thermostat – ensure it works properly.
    • Tires – make sure the tires have adequate tread. All-weather radials are usually adequate for most winter conditions. However, some jurisdictions require that to drive on their roads, vehicles must be equipped with chains or snow tires with studs.
    • Windshield wiper equipment – repair any problems and maintain proper washer fluid level.
  • Freezing Rain creates a coating of ice on roads and walkways.
  • Sleet is rain that turns to ice pellets before reaching the ground. Sleet also causes roads to freeze and become slippery.
  • Winter Weather Advisory means cold, ice and snow are expected.
  • Winter Storm Watch means severe weather such as heavy snow or ice is possible in the next day or two.
  • Winter Storm Warning means severe winter conditions have begun or will begin very soon.
  • Blizzard Warning means heavy snow and strong winds will produce a blinding snow, near zero visibility, deep drifts and life-threatening wind chill.
  • Frost/Freeze Warning means below freezing temperatures are expected.
  • When a Winter Storm WATCH is issued
    • Listen to NOAA Weather Radio, local radio, and television stations, or cable television such as The Weather Channel for further updates.
    • Be alert to changing weather conditions.
    • Avoid unnecessary travel
  • When a Winter Storm WARNING is issued
    • Stay indoors during the storm.
    • If you must go outside, several layers of lightweight clothing will keep you warmer than a single heavy coat. Gloves (or mittens) and a hat will prevent loss of body heat. Cover your mouth to protect your lungs.
    • Walk carefully on snowy, icy, walkways.
    • If the pipes freeze, remove any insulation or layers of newspapers and wrap pipes in rags. Completely open all faucets and pour hot water over the pipes, starting where they were most exposed to the cold (or where the cold was most likely to penetrate).
    • Maintain ventilation when using kerosene heaters to avoid build-up of toxic fumes. Refuel kerosene heaters outside and keep them at least three feet from flammable objects.
    • Avoid traveling by car in a storm, but if you must…
    • Carry an Emergency Supply Kit in the trunk.
      • Keep your car’s gas tank full for emergency use and to keep the fuel line from freezing.
      • Let someone know your destination, your route, and when you expect to arrive. If your car gets stuck along the way, help can be sent along your predetermined route.
      • Eat regularly and drink ample fluids, but avoid caffeine and alcohol.
      • Conserve fuel, if necessary, by keeping your residence cooler than normal. Temporarily close off heat to some rooms.

Learn about the emergency plans that have been established in your area by your state and local government. In any emergency, always listen to the instructions given by local emergency management officials.

Wildfires

Wildfires often begin unnoticed. They spread quickly, igniting brush, trees, and homes. Reduce your risk by preparing now before wildfire strikes. Meet with your family to decide what to do and where to go if wildfires threaten your area. Follow the steps listed below to protect your family, home, and property.

  • People start most wildfires . . . find out how you can promote and practice wildfire safety.
  • Contact your local fire department, health department, or forestry office for information on fire laws. Make sure that fire vehicles can get to your home. Clearly mark all driveway entrances and display your name and address. 
  • Report hazardous conditions that could cause a wildfire. 
  • Teach children about fire safety. Keep matches out of their reach. 
  • Post fire emergency telephone numbers. 
  • Plan several escape routes away from your home by car and by foot. 
  • Talk to your neighbors about wildfire safety. Plan how the neighborhood could work together after a wildfire. Make a list of your neighbors’ skills, such as medical or technical. Consider how you could help neighbors who have special needs, such as elderly or disabled persons. Make plans to take care of children who may be on their own if parents can’t get home.
  • Regularly clean roof and gutters.
  • Inspect chimneys at least twice a year. Clean them at least once a year. Keep the dampers in good working order. Equip chimneys and stovepipes with a spark arrester that meets the requirements of National Fire Protection Association Code 211. (Contact your local fire department for exact specifications.) 
  • Use 1/2-inch mesh screen beneath porches, decks, floor areas, and the home itself. Also, screen openings to floors, roof, and attic. 
  • Install a smoke detector on each level of your home, especially near bedrooms; test monthly and change the batteries at least once each year. 
  • Teach each family member how to use the fire extinguisher (ABC type) and show them where it’s kept. 
  • Keep a ladder that will reach the roof.
  • Consider installing protective shutters or heavy fire-resistant drapes. 
  • Keep handy household items that can be used as fire tools: a rake, axe, handsaw or chainsaw, bucket, and shovel.
  • Design and landscape your home with wildfire safety in mind.
  • Select materials and plants that can help contain fire rather than fuel it. 
  • Use fire resistant or non-combustible materials on the roof and exterior structure of the dwelling. Or treat wood or combustible material used in roofs, siding, decking, or trim with UL-approved fire-retardant chemicals. 
  • Plant fire-resistant shrubs and trees. For example, hardwood trees are less flammable than pine, evergreen, eucalyptus or fir trees.
  • Within this area, you can take steps to reduce potential exposure to flames and radiant heat. Homes built in pine forests should have a minimum safety zone of 100 feet. If your home sits on a steep slope, standard protective measures may not suffice. Contact your local fire department or forestry office for additional information. 
  • Rake leaves, dead limbs, and twigs. Clear all flammable vegetation. 
  • Remove leaves and rubbish from under structures and dispose of them properly. 
  • Thin a 15-foot space between tree crowns, and remove limbs within 15 feet of the ground. 
  • Remove dead branches that extend over the roof. 
  • Prune tree branches and shrubs within 15 feet of a stovepipe or chimney outlet. 
  • Ask the power company to clear branches from powerlines. 
  • Remove vines from the walls of the home. 
  • Mow grass regularly. 
  • Clear a 10-foot area around propane tanks and the barbecue. Place a screen over the grill–use non-flammable material with mesh no coarser than one-quarter inch. 
  • Regularly dispose of newspapers and rubbish at an approved site. Follow local burning regulations. 
  • Place stove, fireplace, and grill ashes in a metal bucket, soak in water for two days, then bury the cold ashes in mineral soil. 
  • Store gasoline, oily rags, and other flammable materials in approved safety cans. Place cans in a safe location away from the base of buildings. 
  • Stack firewood at least 100 feet away and uphill from your home. Clear combustible material within 20 feet. Use only UL-approved woodburning devices.
  • Identify and maintain an adequate outside water source such as a small pond, cistern, well, swimming pool, or hydrant. 
  • Have a garden hose that is long enough to reach any area of the home and other structures on the property. 
  • Install freeze-proof exterior water outlets on at least two sides of the home and near other structures on the property. Install additional outlets at least 50 feet from the home. 
  • Consider obtaining a portable gasoline-powered pump in case electrical power is cut off.
    When Wildfire Threatens
  • If you are warned that a wildfire is threatening your area, listen to your battery-operated radio for reports and evacuation information. Follow the instructions of local officials. 
  • Back your car into the garage or park it in an open space facing the direction of escape. Shut doors and roll up windows. Leave the key in the ignition. Close garage windows and doors, but leave them unlocked. Disconnect automatic garage door openers. 
  • Confine pets to one room. Make plans to care for your pets in case you must evacuate. 
  • Arrange temporary housing at a friend or relative’s home outside the threatened area.
  • Wear protective clothing — sturdy shoes, cotton or woolen clothing, long pants, a long-sleeved shirt, gloves, and a handkerchief to protect your face.
  • Take your emergency supply kit 
  • Lock your home. 
  • Tell someone when you left and where you are going. 
  • Choose a route away from fire hazards. Watch for changes in the speed and direction of fire and smoke.

Radiation Threat

A radiation threat, commonly referred to as a “dirty bomb” or “radiological dispersion device (RDD)”, is the use of common explosives to spread radioactive materials over a targeted area. It is not a nuclear blast. The force of the explosion and radioactive contamination will be more localized. While the blast will be immediately obvious, the presence of radiation will not be clearly defined until trained personnel with specialized equipment are on the scene. As with any radiation, you want to try to limit exposure. It is important to avoid breathing radiological dust that may be released in the air.

  • If you are outside and there is an explosion or authorities warn of a radiation release nearby, cover your nose and mouth and quickly go inside a building that has not been damaged. If you are already inside check to see if your building has been damaged. If your building is stable, stay where you are.Close windows and doors; turn off air conditioners, heaters or other ventilation systems.
  • If you are inside and there is an explosion near where you are or you are warned of a radiation release inside, cover nose and mouth and go outside immediately. Look for a building or other shelter that has not been damaged and quickly get inside.Once you are inside, close windows and doors; turn off air conditioners, heaters or other ventilation systems.
  • If you think you have been exposed to radiation, take off your clothes and wash as soon as possible.
  • Stay where you are, watch TV, listen to the radio, or check the Internet for official news as it becomes available.
  • Remember: To limit the amount of radiation you are exposed to, think about time, distance and shielding.
  • Time: Minimizing time spent exposed will also reduce your risk.
  • Distance: The farther away you are away from the blast and the fallout the lower your exposure.
  • Shielding: If you have a thick shield between yourself and the radioactive materials more of the radiation will be absorbed, and you will be exposed to less.
 

As with any emergency, local authorities may not be able to immediately 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 information as it becomes available.

Extreme Heat

Heat can affect anyone.  However, it is more likely to affect young children, elderly people, and people with health problems.  For instance, people with a medical condition that causes poor blood circulation, and those who take medications to get rid of water from the body (diuretics) or for certain skin conditions, may be susceptible.  Consult with a physician if you have any questions about how your medication may affect your ability to handle heat.

Are you ready for a Heat Wave?  Here is what you can do to prepare yourself and your family.

  • Heat wave:  Prolonged period of excessive heat and humidity.  The National Weather Service steps up its procedures to alert the public during these periods of excessive and heat and humidity.
  • Heat index:  A number in degrees Fahrenheit that tells how hot it really feels when relative humidity is added to the actual air temperature.  Exposure to full sunshine can increase the heat index by 15 degrees Fahrenheit.
  • Heat cramps:  Heat cramps are muscular pains and spasms due to heavy exertion.  They usually involve the abdominal muscles or legs.  It is generally thought that the loss of water from heavy sweating causes the cramps.
  • Heat exhaustion:  Heat exhaustion typically occurs when people exercise heavily or work in a warm humid place where body fluids are lost through heavy sweating.  Blood flow to the skin increases causing blood flow to decrease to the vital organs.  This results in a form of mild shock.  If not treated, the victim’s condition will worse.  Body temperature will keep rising and the victim may suffer a heat stroke.
  • Heat stroke:  Heat stroke is life-threatening.  The victim’s temperature control system, which produces sweating to cool the body, stops working.  The body temperature can rise so high that brain damage and death may result if the body is not cooled quickly.
  • Sunstroke:  Another term for heat stroke.
 
  • Slow down.  Avoid strenuous activity.  If you must do strenuous activity, do it during the coolest part of the day, which is usually in the morning between 4am and 7am.
  • Stay indoors as much as possible.  If air conditioning is not available, stay on the lowest floor, out of the sunshine.  Remember, electric fans do not cool the air, but the do help sweat evaporate, which cools your body.
  • Wear lightweight, light-colored clothing.  Light colors will reflect away some of the sun’s energy.
  • Drink plenty of water regularly and often.  Your body needs water to keep cool.
  • Drink plenty of fluids even if you do not feel thirsty.
  • Water is the safest liquid to drink during heat emergencies.  Avoid drinks with alcohol or caffeine in them.  They can make you feel good briefly, but make the heat’s effects on your body worse.  This is especially true about beer, which actually dehydrates the body.
  • Eat small meals and eat more often.  Avoid foods that are high in protein, which increase metabolic heat.
  • Avoid using salt tablets unless directed to do so by a physician.
  • Heat exhaustion:  Cool, moist, pale or flushed skin; heavy sweating, headache; nausea or vomiting; dizziness; and exhaustion.  Body temperature will be near normal.
  • Heat stroke:  Hot, red skin; changes in consciousness; rapid, weak pulse; and rapid shallow breathing.  Body temperature can be very high – sometimes as high as 105 degrees Fahrenheit.  If the person was sweating from heavy work or exercise, skin may be wet; otherwise, it will feel dry.
  • Heat cramps: Get the person to a cooler place and have him or her rest in a comfortable position.  Lightly stretch the affected muscle and replenish fluids.  Give a half glass of cool water every 15 minutes.  Do not give liquids with alcohol or caffeine in them, as they can make conditions worse.
  • Heat exhaustion:  Get the person out of the heat and into a cooler place.  Remove or loosen tight clothing and apply cool, wet cloths, such as towels or sheets.  If the person is conscious, give cool water to drink.  Make sure the person drinks slowly.  Give a half glass of cool water every 15 minutes.  Do not give liquids that contain alcohol or caffeine.  Let the victim rest in a comfortable position and watch carefully for changes in his or her condition.
  • Heat stroke:  Heat stroke is a life-threatening situation.  Help is needed fast.  Call 9-1-1 or your local emergency number.  Move the person to a cooler place.  Quickly cool the body.  Immerse victims in a cool bath, or wrap wet sheets around the body and fan it.  Watch for signals of breathing problems.  Keep the person lying down and continue to cool the body any way you can.  IF the victim refuses water, is vomiting or there are changes in the level of consciousness, do not give anything to eat or drink.

Thunderstorms & Lightning

In the United States, lightning kills 300 people and injures 80 on average each year. All thunderstorms produce lightning and all have the potential for danger. Those dangers can include tornadoes, strong winds, hail, wildfires and flash flooding, which is responsible for more fatalities than any other thunderstorm-related hazard.Lightning’s risk to individuals and property is increased because of its unpredictability. It often strikes outside of heavy rain and may occur as far as 10 miles away from any rainfall. Most lightning deaths and injuries occur when people are caught outdoors in the summer months during the afternoon and evening.

  • Familiarize yourself with the terms that are used to identify a thunderstorm hazard, including understanding the difference between a severe thunderstorm watch and a severe thunderstorm warning.
  • A thunderstorm watch means there is a possibility of a thunderstorm in your area.
  • A thunderstorm warning means a thunderstorm is occurring or will likely occur soon. If you are advised to take shelter so immediately.
  • Get an emergency supply kit.
  • Remove dead or rotting trees and branches that could fall and cause injury or damage during a severe thunderstorm.
  • Use the 30/30 lightning safety rule. If you see lightning and you cannot count to 30 before hearing thunder, go indoors. Then stay indoors for 30 minutes after hearing the last clap of thunder.
  • If a thunderstorm is likely in your area, postpone outdoor activities.
  • Secure outdoor objects that could blow away or cause damage.
  • Shutter windows and secure outside doors. If shutters are not available, close window blinds, shades or curtains.
  • Avoid showering or bathing during a thunderstorm. Plumbing and bathroom fixtures can conduct electricity.
  • Watch for darkening skies, lightning, increasing winds.
  • Listen to NOAA Weather Radio for information.
  • Go quickly inside a home, building or hard top automobile, if possible.
  • If shelter is not available go to the lowest area nearby and make yourself the smallest target possible but do not lie flat on the ground.
  • If on open water, get to land and shelter immediately.
  • Things to avoid include:
    • Tall, isolated tree in an open area.
    • Hilltops, open fields, the beach, a boat on the water, isolated sheds or other small structures in open areas.
    • Anything metal — tractors, farm equipment, motorcycles, golf carts, golf clubs, and bicycles
      Stay Informed
  • Local authorities may not immediately be able to provide information on what is happening and what you should do. However, you should listen to your battery operated or hand crank NOAA Weather Radio, watch TV, listen to the radio or check the Internet often for official news and instructions as they become available.
  • Do not use electrical items such as computers or television sets as power surges from lightning can cause serious damage.
  • A corded telephone should only be used in an emergency, but cordless phones and cell phones are safe to use.
