In case of indoor shelter

Authorities for public health can give the instruction to stay indoors, e.g. at home or in the office.

  • Seal all entry routes as efficiently as possible
  • Close and lock windows and doors
  • Use wet towels and duct tape to seal gaps under doorways and windows
  • Use tape and plastic, wax, or aluminum wrap to seal gaps around window air conditioning units
  • Go to a basement or other underground area if possible
