Electrical Safety, cont. • The disconnecting means for each service, feeder or branch circuit originating on a switchboard or panelboard shall be legibly and durably marked to indicated its purpose unless such purpose is clearly evident.
Evacuation Procedures Confinement • This is the most important concept in fire safety. An interior fire produces extreme temperatures and deadly smoke. The interior fire's only weakness is its susceptibility to confinement. • If you discover a fire in a room: • Close the door to the room as you exit. • Close all doors in the immediate area, if possible.
Evacuation Procedures, cont. Report the Fire • Reporting a fire in your building can best be accomplished by: • Pull the nearest interior fire alarm pull station. • Call the Fire Department emergency telephone number • 9-911 on Stanford University telephones • 911 on telephones with Palo Alto prefixes.
Evacuation Procedures, cont. Evacuation • Evacuation from the area of the fire to a safe location is of primary importance in the management of a fire emergency. • If the fire is in your area or if the fire alarm sounds, leave the building in an orderly manner and assemble at a predetermined Emergency Assembly Point (EAP) located a safe distance from the building.
Evacuation Procedures, cont. Fighting the Fire • This is best accomplished by confining the fire by closing doors. However, a portable fire extinguisher may be used if: • The fire is small • You have been trained to use a portable fire extinguisher
NOTE Heroic efforts by persons fighting fires have resulted in fatalities when confinement, reporting and evacuation procedures were neglected. Remember, the emphasis on protecting lives and property by Confinement, Reporting and Evacuation
