VIDEO: The screams. The bodies lying across the freeway. The people trying to run away from a toxic cloud before collapsing to the ground. Fifty years later, retired Houston firefighters say they still remember every detail from one of the deadliest disasters in Houston history. “It looked like a war zone,” retired Houston firefighter Brad Rilay said.
On May 11, 1976, a tanker carrying more than 7,000 gallons of anhydrous ammonia plunged off the 610 West Loop ramp and crashed onto the Southwest Freeway below. The impact ripped open the tanker, sending a massive cloud of toxic ammonia into the air during the middle of the morning rush.
Seven people died. Dozens more were injured. And the disaster changed the Houston Fire Department forever. Rilay was only 20 years old when he responded to the scene. That morning had started like any other shift.
Rilay said he and a district chief had just finished another call farther down the Southwest Freeway when dispatchers warned crews about a tanker crash involving ammonia near the West Loop interchange. As they drove toward the area, traffic completely locked up.
Rilay said he ended up driving against traffic on the freeway shoulder just to reach the scene. When they arrived, he said the destruction was overwhelming.
“Man, it looked like a war zone, you know, the parts of the truck scattered everywhere, and the truck driver’s body was lying in the middle of the road,” Rilay said.
The crash scene stretched across the freeway. Pieces of the tanker and destroyed vehicles were scattered throughout the interchange. Victims were already dying from exposure to the fumes.
Rilay remembers immediately finding several people on the ground struggling to breathe. “We immediately came across three people, one man who had already died, and there were two who were struggling to breathe,” he said.
At the time, Houston firefighters had little training on hazardous material incidents and almost no specialized equipment to handle a chemical release that large. Firefighters grabbed an air pack from the chief’s car and tried helping victims breathe through the mask.
“But I don’t know how much good that did,” Rilay said quietly. What stayed with him most was the helplessness. “You know, have a brown mucus coming out of their mouth and their nose, and the feeling of not being able to help them,” Rilay said.
