Shelter in Place
During an emergency when chemical, biological or radiological materials have been released accidentally or deliberately into the air, those hazardous contaminants may require that Nevadans "shelter in place." This means staying inside to protect you and your family from toxins outside, and is recommended when evacuation is not appropriate. The following is more information from Public Health Preparedness at the Nevada Division of Public and Behavioral Health on this aspect of emergency preparedness.
To shelter in place, choose a small room with few or no windows, and seek protection there until the situation outside is brought under control. It is not necessary to seal off your home or windows. Close and lock all windows and exterior doors. Close the window shades, blinds or curtains if you are told there is a danger of explosion. Turn off all fans, heating and air conditioning systems. Make sure you have access to your Emergency Supply Kit and a battery-operated radio.
Prepare your office space for a shelter-in-place situation. Gather a flashlight with extra batteries, a battery-powered radio, a one-day supply of non-perishable food for each person in the office and a gallon of water per person. Consider also stocking a personal three-day supply of prescription medications, a general supply of over-the-counter drugs and an extra pair of eyeglasses or contact lenses and supplies.
In the Car
If you are driving a vehicle when you hear an alert on the radio to shelter in place, assess your location. If you are very close to your home, office or a public building, go there immediately. If you are unable to get to a home or public building quickly and safely, then pull over to the side of the road and stop your vehicle at the safest place possible. If it is sunny outside, consider parking under a bridge or shady spot to avoid becoming overheated. Turn off the engine, and close windows and vents. If possible, seal the heating/air conditioning vents with duct tape. Listen to the radio for updated advice and instructions - stay where you are until you are told that it is safe to get back on the road. Be aware that some roads may be closed, or traffic detoured.
