Factory automated fire suppression system

I toured a very large newspaper printing company back in the 80's. Remember when news papers were a thing? Had a huge press press room. With multiple presses. Automatic paper changers held several multi-ton rolls of news print. A new roll would be spliced to the old roll without stopping the press. The press ran so fast the multi ton roll of paper would onlu last a few minutes. Ink was pumped from 55 gallon barrels to insure a constant supply to the print head. I cannot remember the actual speed in MPH the paper, but is was very high.

The point is, if something happened, and ignited that paper and ink combination, the press would continue "stoking' until it could coast to a stop. There a HUGE C02 tank right outside the building. When the buzzer went off, and the red lights started flashing, the pressmen had only seconds to escape that room before it was flooded with CO2.
