The Movement of Air, the Movement of Smoke - Fire Dynamics - Structural Firefighting

Dr. Michael Reick

By Robert Maloney

“If you think about air movement in buildings, you have to also think about the movement of smoke,” Michael Reick told attendees at “Fire Ventilation and Flow Path Control” workshop Monday afternoon at FDIC International. A regional fire chief for the county of Göppingen, Germany, he is also a research engineer and affiliated with the Fire Research Laboratory at the University of Stuttgart.

Noting that Germany, approximately 50 percent of the population live in multi-story dwellings, the stairway is the most important room in such a building. Since it is an exit route for the residents, responders must not allow smoke to spread there from the fire.

Controlling the flow path properly according to the situation will determine the course of the fire. If the air inlet or outlet is increased, the result may be fire growth and spread. If the inlet or outlet is limited, fire growth may likewise be limited.

Reick said the door to the fire compartment should be kept closed to keep the smoke from entering uninvolved areas and to avoid smoke damage. He also outlined several possibilities for maintaining door control.

He also reviewed the use of the fire curtains to control air flow into the fire compartment and the use of fans in keeping areas clear of smoke. Reick used several fire videos to illustrate the effects of proper and improper actions at fires regarding smoke containment, ventilation, and fire control.

Limiting fire damage through coordinated ventilation can be accomplished by controlling the door to the fire compartment, he said. However, he cautioned that “no one size fits all” regarding fire tactics, but that “keeping the situation stabilized is the goal.”

Williamson County Emergency Services District (TX) Breaks Ground on Second Fire Station

President Dan Clark of the ESD Board of Commissioners took time to thank the developers of Santa Rita Ranch for the donation of land to build on.  

Horne was excited to see the project begin, saying Santa Rita was planned for 6,500 homes upon completion, with another 200 acres of multi-family and retail development.  

“That means that within this location right here, there will be somewhere in the neighborhood of 30,000 people eventually living here in this area,” Horne said. “We’re building a future, and the future of that is being staked today to what we’re doing with the fire department and having this. These are the basics of what you’ve got to have when you’re in a community to service the people who are here. We are honored to be able to have the fire department and have you guys choose this site out here.”

The theft was discovered Saturday morning at Station 22 off Seminole Pratt Whitney Road.  

"This is how we document when we come to a scene come to your house, we input all of your information and then it uploads to our computer software and prints out a report for the hospital," said Palm Beach County Fire Rescue Captain Albert Borroto.

Borroto reassured WPTV no personal information was compromised.

"They had been shut off for a long enough time that there was no personal information that was accessible on the tablets. They were cleaned." Also taken, a fire fighter's bunker coat. "It was fire fighting bunker gear it is protective equipment for firefighters when we go into burning buildings."

Bettendorf (IL) Fire Station to Double in Size by June

Every passing year on the force brings about change. Ask Assistant Fire Chief Steven Knorrek.  

"When I first started, we had a drive-thru bay on the side that's closest to City Hall, and that disappeared," remembers Knorrek.

Right now, the change is work on new fire bays and a driveway at the department.

The fire station's not the only place growing, with two major developments in downtown. One is the Bridges lofts right next to the fire station, and then the new Acentra Credit Union that will bring in new people and new jobs according to Bettendorf Mayor Bob Gallagher.
