This will help prevent the spread of smoke and fire. Shut off appliances and other equipment. Do not turn off the lights. Extinguish the fire by using a portable fire extinguisher if safe to do so. Stay close to the floor until you are sure there is no smoke.
Smoke contains hot and toxic gases.
Take your keys. If you encounter fire or unsafe conditions, you may have to return to your room or office. Check each door for heat before opening. Open the door slowly and check for smoke. Shut your room or office door and all fire doors between you and the fire.
