It’s October 23, 1989. Workers perform routine maintenance on Reactor 6 at the gigantic Houston Chemical Complex in Pasadena.
It’s not a complicated procedure, but it still calls for caution. The high-pressure reactor is filled with a cocktail of highly flammable material. There's no room for mistakes.
Step by step, workers follow the maintenance procedure. Suddenly, a deafening hiss pierces the air as the reactor violently releases its entire content into the factory yard. Engulfing everything in a cloud of combustible vapors.
The workers know it takes only a tiny spark to blow everything up, so they start to run.
