HazMat Team Spotlight: Houston Fire Department

Slideshow Images: Houston FD HazMat Team Houston is the fourth largest city in the United States, with a population of 1.9 million people and covering an area of 617 square miles. Houston is located in southeast Texas approximately 48 miles from the...

Houston's Hazmat personnel operate as a team with confidence in their abilities and in each other. Captains function like quarterbacks and not coaches. The Houston team is a dedicated team with 11 on-duty technicians per shift. Approximately 20 other technicians are assigned to other companies throughout the city but are not part of an organized response. All hazmat team members work a 24-hour on, 24-hour off, 24-hour on and five days off shift. The response area for the hazmat team is the entire City of Houston and Harris County. They have responded as far away as Austin County, Montgomery County and Galveston. Houston Hazmat relies heavily on the Channel Industries Mutual Aid Group (CIMA), an industrial organization, for backup during incidents. They also have mutual aid agreements with the newly formed Harris County Hazmat Team and the Ponderosa Volunteer Fire Department team. Assistance is also available from the Metropolitan Medical Strike Team (MMST) based in Houston.

Major Hazmat Incidents

Houston has experienced numerous major hazardous materials incidents, before and since the hazmat team was formed. Anhydrous ammonia has been the source of several incidents. One emergency involved an anhydrous ammonia tanker truck on May 11, 1976. The MC 331 crashed through a guard rail and released ammonia on a freeway below. Many motorists were trapped in their cars by the ammonia vapors; seven died and 150 were injured. Several firefighters were also treated for ammonia inhalation.

Another ammonia incident occurred on Dec. 11, 1983, when the Borden's Ice Cream Plant experienced an explosion from leaking anhydrous ammonia used for cooling at the plant. There were no deaths or injuries. Several events delayed firefighters from entering the building before the explosion occurred that certainly would have caused firefighter injuries if not death.

One such delay occurred when firefighters outfitted the plant engineer with SCBA and provided impromptu training so he could enter with them and point out a leaking valve. The explosion occurred as they walked toward the building. Hazmat personnel had not yet arrived on scene when the explosion took place, and that may have saved them from injury and death as well.

At the time, there was a great deal of surprise among firefighters that ammonia would burn or explode. Previous procedures were to enter the building with chemical protection and stop the leaks. Following the Borden plant incident, procedures were changed to ventilate the building thoroughly before entering to plug leaks.

One of the largest fires to ever challenge the Houston Fire Department occurred on June 24, 1995. Seven alarms were transmitted for the Houston Distribution Warehouse complex located at 8550 Market St., starting with the first at 8:33 A.M. Two-thirds of the city's on-duty force was called on to fight the stubborn fire over the next 31 hours. Thirty-one engine companies and 14 ladder companies fought the fire. Warehouses in the complex were loaded with organic and inorganic chemicals, including corrosives, motor oils, plastics, solvents, cleaning compounds, lubricants, organophosphorus pesticides, flame retardants and metallic compounds.

Hazmat units responded on the second alarm. The fire overcame the building's sprinkler system and firefighter hose streams, and by 11 A.M. the building was totally involved. Exposures included five tractor-trailers loaded with organic peroxides and a liquefied petroleum gas rail car. Lines were placed in service to protect exposures and protective booms were placed to keep runoff water from entering storm drains. Mutual aid was requested from Channel Industries Mutual Aid (CIMA) at 7:30 P.M., which brought 10 foam tankers, four 2,000-gpm monitors mounted on trailers and a 6,700-gallon foam tanker to the scene.

After pouring foam on the fire all night, firefighters brought it under control at around 3 o'clock the following morning. Fire units remained on scene for several days putting out flair ups. Despite the magnitude of the fire and the chemicals involved, only three firefighters sustained minor injuries.
