Chemical companies could allow vendors to sponsor various alarms in their plants: "the Flowserve(tm) High-Level alarm on T102 is active!"..."the Flowserve(tm) High-Level alarm on T102 is active!". Then there could be a contractual minimum for the number of times that ad needs to be served to operators and engineers, otherwise the chemical plant would need to refund Flowserve for the unused ad campaign credits. Lowering the threshold of the high-level alarm would optimize ad revenue!
