Fire/Life Safety– Willis Tower has one of the most complete life safety systems ever devised for a high-rise building. All steel is fireproofed. Automatic sprinklers cover each of the 4.5 million gross square feet of space. Duct-mounted smoke detectors are designed to pinpoint the source of the smoke and a computer-activated system will exhaust the smoke from affected areas. The self-contained backup emergency power supply supports the alarm system, fire pumps, communication system, emergency lighting and select elevators in the event of an electrical failure. Fire Sprinklers – The building is protected throughout by automatic sprinklers. The Lower Level South and North Loading Docks, Level 1A parking garage and Sky Deck entrance are protected by dry-pipe sprinkler systems. Fire Pumps – The sprinkler and standpipe systems are supplied by ten fire pumps. The fire pumps, manufactured by Peerless, have capacities of 500, 1,000, or 1,500 gallons per minute. Fire Extinguishers – Fire extinguishers are installed throughout the Property.
