In a bizarre story out of Denver, Safeway employee, Michael Julius Ford, spent the last 72 minutes of his life hunting co-workers and setting fires. With the threat of being killed, other Safeway employees used extinguishers to put out the fires.

Bangkok - Fire extinguishers have become the latest lethal weapon in the militants’ arsenal in Thailand’s troubled deep South. On May 9, a mobile phone was used to detonate a fire extinguisher bomb exploded in Narathiwat, the ninth such device to be used there in recent weeks.
After a "suspicious" passenger left the lavatory of the plane, an alert flight attendant noticed a fire extinguisher was out of place and notified the pilots. The plane was diverted as a safety measure.
Fire extinguishers have been used as improvised explosive devices (IEDs) so this flight attendant was wise to call attention to it.
One way to immediately know if your extinguishers have been removed, depressurized or blocked is to monitor them with en-Gauge.
A man with a history of creating pipe bombs is suspected of leaving another bomb -- this time in a fire extinguisher -- in his car.
The car had been in the police impound lot before being picked up by family. There's a question whether the car had been searched by police before being released.
