- Do not use kitchen or bathroom vents
- Set thermostats so air conditioners, furnaces and hot water heaters do not come on
- Do not use fireplaces. Close all dampers
- Do not operate the clothes dryer
- Stay in an inside room as far away from windows and doors as possible
- Avoid smoking as it contaminates the air
- Do not leave the building until told to
- Stay tuned to local TV or radio for information
- Do not use the telephone
