“At approximately 2 a.m. CDT, we were notified by the Harris County Emergency Operations Center (EOC) of two explosions and black smoke coming from the Arkema Inc. plant in Crosby, Texas,” Arkema wrote in a statement.“At approximately 2 a.m. CDT, we were notified by the Harris County Emergency Operations Center (EOC) of two explosions and black smoke coming from the Arkema Inc. plant in Crosby, Texas,” Arkema wrote in a statement.
The statement goes on to say that although the plant followed hurricane preparation protocol, “unprecedented flooding overwhelmed our primary power and two sources of emergency backup power. As a result, we lost critical refrigeration of the products on site. Some of our organic peroxides products burn if not stored at low temperature.”The statement goes on to say that although the plant followed hurricane preparation protocol, “unprecedented flooding overwhelmed our primary power and two sources of emergency backup power.

“Organic peroxides are extremely flammable and, as agreed with public officials, the best course of action is to let the fire burn itself out,” the statement reads.“Organic peroxides are extremely flammable and, as agreed with public officials, the best course of action is to let the fire burn itself out,” the statement reads.

“The fire will happen. It will resemble a gasoline fire. It will be explosive and intense in nature... as the temperature rises, the natural state of these materials will decompose. A white smoke will result, and that will catch fire. So the fire is imminent. The question is when,” spokesperson Janet Smith said.“The fire will happen. It will resemble a gasoline fire.

Rachel Moreno, a spokeswoman for the county fire marshal’s office, said it is unclear whether all residents obeyed the evacuation order for the 1.5 mile radius of the plant, adding that the office has received an unconfirmed report of a woman who may still be in the evacuation zone.Rachel Moreno, a spokeswoman for the county fire marshal’s office, said it is unclear whether all residents obeyed the evacuation order for the 1.5 mile radius of the plant, adding that the office has received an unconfirmed report of a woman who may still be in the evacuation zone.

The plant makes organic peroxides used in the production of plastic resins, polystyrene, paints, and other products.The plant makes organic peroxides used in the production of plastic resins, polystyrene, paints, and other products.
Organic peroxides are "relatively unstable compounds which can decompose spontaneously and sometimes explosively,"according to Arkema's Luperox website. They are "generally flammable and burn vigorously." 
When such compounds reach a temperature above the SADT (Self Accelerating Decomposition Temperature) the reaction becomes "uncontrolled and violent."
