• Rarely fail to operate
• There never has been a multiple death in a fully
  operational sprinklered building

  five or fewer heads
• Less interruption of business and less water
  damage
• Enhances life safety

How Automatic Sprinklers Enhance Life Safety

• Water is discharged directly on the fire
• The fire is usually controlled while it is in the
  incipient (growth) stage
• Products of combustion are limited
• Sprinklers help prevent fire spread
• Occupants feel safer in a sprinklered building
  thus reducing the likelihood of panic
