In a Vehicle
If you are very close to home, your workplace, or a public building, go there immediately and go inside. If you are unable to get indoors quickly and safely, continue driving away from the nuclear plant for a distance of at least 10 miles. Close windows and vents. If possible, set the ventilation system to recirculate the air inside the vehicle. Avoid shutting off your air conditioning system if it is a hot day. Overheating your body can be dangerous. Listen to the radio for updated information and instructions.
Employers should close the office, making any customers, clients, or visitors in the building aware that they need to stay until the emergency is over. Close and lock all windows, exterior doors, and any other openings to the outside. Avoid overcrowding by preselecting several interior rooms with the fewest number of windows or vents. Switch the ventilating and air conditioning systems to recirculate the air inside the structure, if possible. Employers should ask employees, customers, clients, and visitors to call their emergency contacts to let them know where they are and that they are safe. If the business has voicemail or an automated attendant, it should be switched to a recording that indicates that the business is closed, and that staff and visitors are remaining in
the building until authorities advise it is safe to leave. One person per room should write down the names of everyone in the room. 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 or television for updated advice and instructions.
