1. Advise everyone to stay inside.
Announce to everyone in the building that the City has issued a Shelter-in-Place advisory. Recommend that people not leave the building during this time unless specifically ordered to do so by police or fire personnel. Leaving the building could result in exposure to toxic chemical vapors.
2. Close all doors, windows and other sources of outside air.
Close and lock windows for a tighter seal. Control access doors (locking will provide a tighter seal). Post a “Shelter-in-Place in Effect – Controlled Access” sign in the window so that people outside will know you are closed and Sheltering-In-Place. If additional people want to enter to Shelter-in-Place, minimize the time the door is held open. Move others in the room away from the door that is opened. People who insist on leaving the building should be allowed to leave, but advise them it is at their own risk since emergency officials have issued a Shelter-in-Place advisory.
3. Turn off all air conditioning or heating systems
Your building’s thermostats or air-handling cutoff switches should be labeled, and employees should be trained where they are located and how they work. Ceiling fans or portable fans can be used inside to keep cool while the ventilation system is shut down.
4. Turn on your battery operated radio to a local radio station
Emergency officials in Sarnia recommend tuning to one of the local radio stations for emergency information. Officials will be providing the news media with updated information on the locations that should continue to Shelter-in-Place. If you have a television available, Cogeco Cable will also provide news reports, and should scroll information during the event.
5. Stay off the telephone
Avoid using the phone so it is available to receive the informational call. Do not call 9-1-1 to get more information. Only call 9-1-1 if you need immediate assistance with a life-threatening emergency. Overloaded telephone circuits (including cellular phone calls) can prevent actual emergency calls from getting through.
