"Literally in an instant, these families have been ripped apart," Abbott said. "These lives in this community will be put back together."

Abbott also issued a stern warning to anyone in the area caught price-gouging.

"It seems like when tragedies arise, they are followed by price gouging," he said. "My office has declared a warning in regard to price gouging. If anyone tried to profit off this tragedy, they will be facing the wrong end of a lawsuit from the Texas attorney general."

  • Operating procedures failed to address consequences of deviation
  • Poor employee training records
  • The company had not developed a formal written maintenance program

2:45 p.m. ET: Texas officials will not talk about what may have caused the massive explosion, but Nim Kidd with Texas Emergency Management said that on site at the West Fertilizer Plant were tanks holding anhydrous ammonia, which can be kept as a liquid under pressure.

Anhydrous ammonia is a toxic liquid that, when concentrated, is corrosive to tissues upon contact, according to the Center for Disease Control and Prevention.

Also on site at the West Fertilizer Plant was ammonium nitrate, which is a solid product.

"A lot of people don't like putting water and ammonium nitrate together," Kidd said today. "Usually, when you mix those two, you have to have something that confines it, in order to make it a dangerous product.

"I'll tell you, a lot of firefighters will use their number one tool, which is water, in a hazardous materials chemical situation like that, to cool the surrounding environments, to cool those other tanks, and to keep them from cooking off or exploding," he said.

Ammonium nitrate was used by Timothy McVeigh in the Oklahoma City bombing, which killed 168 and injured over 680 people. The bombing took place 18 years ago this week.

1:31 p.m. ET: The National Response Team of the Bureau of Alcohol, Tobacco, Firearms and Explosives, along with ATF special agents from the Houston Field Division, has been activated to join the investigation of the West Fertilizer Plant fire.

"This has been a week of loss and tragedy for the nation," Acting Special Agent in Charge of ATF Houston Field Division Crisanto Perez said today. "ATF is committed to working alongside state and local law enforcement by bringing its expertise to determine the origin and cause of this horrific incident. ATF will provide whatever resources necessary to thoroughly investigate and provide answers."

"Last night was truly a nightmare scenario for that community," Perry said. "West is a really small community. And just a few thousand people. Anyone who grew up in a small town like West, they know that this tragedy has most likely hit every family, and has touched practically everyone in that town. I ask all Texans and Americans to join me and [his wife] Anita in keeping them in our prayers."

"I want to thank the first responders who worked tirelessly through the night to contain the situation and treat the wounded. My administration, through FEMA and other agencies, is in close contact with our state and local partners on the ground to make sure there are no unmet needs as search and rescue and response operations continue," Obama added.

11:40 a.m. ET: Speaking to reporters, Waco police spokesman Sgt. William Patrick Swanton said that more than 160 people have been injured, possibly more.

"I'd imagine that's increased at this point," he said.

Swanton also clarified that earlier reports of looting in the area were overestimated, and that there was only one instance of a looter.

"I have confirmed at least there was an incident last night when they thought they may have had a looter," he said. "It was an isolated incident."

Destruction in the area had varied, Swanton said.

"It ranges from broken windows to complete devastation. There are homes that are no longer homes … walls were ripped off, roofs were peeled back."

Swanton told reporters that the cool weather in the area has been helpful, but officials want to rescue survivors before rain increases.

"As the hours go by with the temp getting cooler, with rain here, we certainly want to find folks, if they're in the environment, injured. Numerous search teams are searching as rapidly as they can to save these people," he said.

10:31 a.m. ET: Aboard Air Force One en route to Boston, President Obama called Texas Gov. Rick Perry to offer any federal resources that may be needed to assist in the ongoing response-and-recovery effort.

"We're still missing 3-4 firefighters," he said. "No police or EMS are missing, as far as I'm aware."

Swanton said that the "rough number" of fatalities remains at 5-15, but emphasized that it is still an estimate.

Swanton also said that a significant area of the fertilizer plant had been destroyed, and that homes were leveled as far as five blocks away.

"Homes have been destroyed. Part of that community is gone," he said.

A small amount of looting had been reported in the area, Swanton said. There are some unidentified people in the area.

"I can't tell you the number of looters or whether they have been caught … that is a significant concern for us," he said.

Authorities are now doing a more methodical search - under beds, in closets - and are still in search in rescue mode, and are not yet in recovery mode.

There is no word yet on the cause of the fire, Swanton said.

4: 11 a.m. ET: ABC Chief Health and Medical Editor Dr. Richard Besser says a continuing danger from the Texas fertilizer plant explosion and fire is exposure to ammonia.

"What you see with high level ammonia exposure is damage to your eyes, to your throat, to your nose, to your esophagus when you swallow," Besser told ABC News Radio. "A blast that's going in one direction, if you get a change in the wind, it can come to another neighborhood and be affected."
