Sheltering : Learn how to safely shelter in place.
In an emergency like a chemical spill, you may be told to “shelter in place”. This means to make the place where you are a safe place to stay until the danger has passed. Shelter in place orders are given when it would be dangerous for you to go outside.
Notification - Warning sirens may be used to warn people that it is not safe to be outside. Emergency responders may go door to door in the affected area. They may also use loudspeakers from police or fire vehicles to give instructions. Information will also be given over television and radio using the Emergency Alert System.
What to do in a hazardous materials incident - The first thing to do when a chemical spill or similar event occurs is to get information. Turn on the television or radio to find out if your area is affected and what steps to take. Never call 911 to get information about an emergency. Only call 911 if you are injured or need assistance.
If you are told to shelter in place you should close all doors and windows and shut off fans and air conditioners. Take your family to a room with as few doors and windows as possible. You may be told to put towels or tape around the cracks of the windows and doors. Follow emergency instructions carefully. Make sure you take a battery-powered radio with you so that you will know when the danger has passed. Power in your area may be shut off during the incident.
