Depending on your circumstances and the type of emergency, the first important decision is whether you stay put or get away. You should understand and plan for both possibilities. Use common sense and available information, including what you are learning here, to determine if there is immediate danger. In any emergency, local authorities may or may not immediately be able to provide information on what is happening and what you should do. 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 "shelter-in-place." However, you should watch TV, listen to the radio, or check the Internet often for information or official instructions as it becomes available. If you are specifically told to evacuate or seek medical treatment, do so immediately.

Use telephones, televisions, and radios for receiving instructions or emergency information. The Internet may be a valuable source of information during an emergency.

If you intend to include a shelter-in-place option in your emergency plan, be sure to keep the following in mind:

	Implement a means of alerting your employees to shelter-in-place that is easily distinguishable from that used to signal an evacuation. Train employees in the shelter-in-place procedures and their roles in implementing them. Train employees for shelter-in-place procedures just the same as you would for evacuation procedures.
Alarm methods may vary depending on the type of emergency

Close the business.

• If there are customers, clients, or visitors in the building, provide for their safety by asking them to stay – not leave. When authorities provide directions to shelter-in-place, they want everyone to take those steps immediately. Do not drive or walk outdoors.
  
  

Unless there is an imminent threat, ask employees, customers, clients, and visitors to call their emergency contact to let them know where they are and that they are safe. Turn on call-forwarding or alternative telephone answering systems or services. If the business has voice mail or an automated attendant, change the recording to indicate that the business is closed, and that staff and visitors are remaining in the building until authorities advise it is safe to leave.

Have employees and anyone else in the building call their emergency contacts, then turn on answering systems.

Quickly lock exterior doors and close windows, air vents, and fireplace dampers. Have employees familiar with your building’s mechanical systems turn off all fans, heating and air conditioning systems, and clothes dryers. Some systems automatically provide for exchange of inside air with outside air. These systems, in particular, need to be turned off, sealed, or disabled. If you are told there is danger of explosion, close the window shades, blinds, or curtains.

Close or tape-off all vents in the room.

Gather essential supplies such as a first-aid kit.

Gather essential disaster supplies, such as nonperishable food, bottled water, battery-powered radios, first-aid supplies, flashlights, batteries, duct tape, plastic sheeting, and plastic garbage bags. Select interior room(s) above the ground floor, with the fewest windows or vents. The room(s) should have adequate space for everyone to be able to sit. Avoid overcrowding by selecting several rooms if necessary. Large storage closets, utility rooms, pantries, copy and conference rooms without exterior windows will work well. Avoid selecting a room with mechanical equipment like ventilation blowers or pipes, because this equipment may not be able to be sealed from the outdoors.

• It is ideal to have a hard-wired telephone in the room(s) you select. Call emergency contacts and have the phone available if you need to report a life-threatening condition. Cellular telephone equipment may be overwhelmed or damaged during an emergency.
  
  

Take your emergency supplies and go into the room you have designated. Seal all windows, doors, and vents with plastic sheeting and duct tape or anything else you have on hand. Consider precutting plastic sheeting (heavier than food wrap) to seal windows, doors, and air vents. Each piece should be several inches larger than the space you want to cover so that it lies flat against the wall. Label each piece with the location of where it fits. [See Figure 1] Write down the names of everyone in the room, and call your business’ designated emergency contact to report who is in the room with you, and their affiliation with your business (employee, visitor, client, customer). Listen to the radio, watch television, or use the Internet for further instructions until you are told all is safe or to evacuate. Local officials may call for evacuation in specific areas at greatest risk in your community.

• Chemical Stockpile Emergency Preparedness Program (CSEPP). Federal Emergency Management Agency (FEMA). Describes the Chemical Stockpile Emergency Preparedness Program (CSEPP) as a unique partnership between FEMA and the U.S. Army, given FEMA's long-standing experience in preparing for and dealing with all types of emergencies and the U.S. Army's role as custodian of the U.S. chemical stockpile. Since 1988, FEMA and the U.S. Army have assisted communities surrounding the eight chemical stockpile sites to enhance their abilities to respond to the unlikely event of a chemical agent emergency.
   
• Planning Protective Action Decision Making: Evacuate or Shelter in Place? Oak Ridge National Laboratory (ORNL), (2002, June), 108 KB PDF, 40 pages. Evaluates the decision of whether to evacuate or shelter-in-place. A successful evacuation removes people from the affected area and avoids exposing them to a harmful concentration of the toxic chemical. An inappropriate decision to evacuate, on the other hand, can have negative consequences if it results in the population of the affected area being caught outdoors or in their vehicles when contamination enters the area. Sheltering can be worse than evacuation if shelters are leaky, people are not told when to come out of the shelter, or the release continues for a long time.
  
  
• Make a Plan - Deciding to Stay or Go. Ready.gov (U.S. Department of Homeland Security), (2003). Identifies the first important decision after an incident occurs is whether to shelter-in-place or evacuate. Advises that local authorities may or may not immediately be able to provide information on what is happening and what you should do. However, you should monitor TV or radio news reports for information or official instructions as they become available.
   
• Design Guidance for Shelters and Safe Rooms. Federal Emergency Management Agency (FEMA) Publication 453, (2006, May). Also available as a 12 MB PDF, 264 pages. Covers a range of protective options, from low-cost expedient protection (what is commonly referred to as sheltering-in-place) to safe rooms ventilated and pressurized with air purified by ultra-high-efficiency filters. These safe rooms protect against toxic gases, vapors, and aerosols (finely divided solid or liquid particles).
  
  
• Shelter-in-Place in an Emergency. American Red Cross, (2003). Shelter-in-place means selecting a small, interior room, with no or few windows, and taking refuge there. It does not mean sealing off your entire home or office building. Instructions are provided in this fact sheet.
