Other Fire Safety Devices

• Fire Sprinklers
• Fire Alarms
• Fire Curtains
• Flameproofing
• Fire Curtain
• Smoke Vents

14
Fire Sprinklers

• Small glass tube that is filled with a red liquid
• When the liquid is heated it will expand and
  break the glass.
• Thus releasing the water that is stored in the
  sprinkler lines
• Has nothing to do with smoke only heat

15
Fire Alarms

• Pull on the wall
• When activated the alarm alerts the fire
  department and all in the buidling

16
Flame Proofing

• Nothing is fire proof. At a certain temperature
  everything will burn.
• In flame proofing a chemical is applied to the
  soft goods so they will resist an open flame.
• This is the main reason we do not touch the soft
  goods.

17
Fire Curtain

• Large drop directly behind the proscenium arch
• Once was made from asbestos. Now made from
  fiberglass.
• Has 3 main functions
• Inhibit smoke from coming into the audience
• Inhibit the fire from spreading into the house
• Psychological - if the audience cant see the fire
  then they dont know how big it is getting

18
Smoke Vents

• Located in the ceiling of the Performance Hall.
• When there is a fire they can be opened to feed
  the fire.
• The added oxygen will help the fire from
  spreading since it will not run out of oxygen.

Exits

• Most people will try to exit the same way they
  entered.
• Be aware of the possible exits (windows are
  possible exits)
• DO NOT GO BACK IN THE BUILDING THAT IS ON FIRE.
  (Fun Fact the only fatality in Plano last year
  was due to a man going back into a burning house
  for his cell phoneyour phone can be replaced,
  but you cannot!)
