Fire in Houston Office Building

There was a fire last week in a Houston office building. It was a 6 story building and three people were killed and insured at least 6 or more. Many others climbed down ladders to safety. The fire broke out at the end of the business day. Some men who work on the 6th floor were outside when they heard an explosion and then glass shattering. They said they called authorities while a person driving by ran into the building and pulled the fire alarm. The sprinklers apparently don't go off until the alarm is pulled. One man on the fourth floor said he was in the atrium when he smelled smoke and then saw the fire. When he left the fire was raging as he looked back. A close call. It looked like the entire suite was on fire. It just took seconds. Alot were suffering from smoke inhalation. The building was built in the early l980's.
