\u0022Now the thing\u0026#039;s exploded, and people don\u0026#039;t know what\u0026#039;s seeping into their air and their homes.\u0022 —Lydia DePillis\u0026rlm;,\u0026nbsp;Houston ChronicleTwo explosions and \u0022plumes of black smoke\u0022 were reported early Thursday morning at an Arkema chemical plant in Crosby, Texas following warnings from Arkema CEO Richard Rowe Wednesday night that \u0022high water and lack of power\u0022 caused by Hurricane Harvey placed the facility at serious risk.In a statement on Thursday, Arkema urged residents to stay clear of the site and cautioned that the \u0022threat of additional explosion remains.\u0022The company continued:As we communicated in recent days, our site followed its hurricane preparation plan in advance of the recent hurricane and we had redundant contingency plans in place. However, 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.CBS19, the Houston affiliate, first reported the explosions early Thursday and noted that black smoke was emerging from the area.Arkema\u0026#039;s CEO warned Wednesday night that any fire resulting from exploding chemicals would likely \u0022resemble a large gasoline fire.\u0022\u0022The fire will be explosive and intense,\u0022 he concluded.Drone footage shows a chemical plant flooded in Baytown, Texas, 35 miles east of Houston. https://t.co/dm7b5pLzkJ #Harvey pic.twitter.com/EPNMqVaLpD— USA TODAY (@USATODAY) August 28, 2017As CNN noted, \u0022one deputy was hospitalized after he inhaled fumes\u0022 from the plant. \u0022Nine others drove themselves to the hospital as a precaution.\u0022Green groups have in recent days warned that explosions of this kind were likely to result from a massive rain event like Hurricane Harvey striking the heart of the petrochemical industry. As the Huffington Post noted, \u0022Arkema is among dozens of chemical plants and refineries in the Houston area, many of which have sustained damage in this week\u0026#039;s flooding, causing harm to residents\u0026#039; health and the environment.\u0022\u0022Living just two miles from one of the largest collections of chemical plants and refineries, I\u0026#039;ve seen the black smoke burning off from these deadly and dangerous plants, I\u0026#039;ve smelled the oil and chemicals, and I know the fear that strikes so many of our communities on a daily basis, which has been magnified by Harvey,\u0022 said Sierra Club organizer Bryan Parras. \u0022Perhaps the most terrifying thing at the moment is that we simply don\u0026#039;t know what\u0026#039;s happening at these facilities.\u0022Refineries have already begun to emit dangerous pollution as a result of Hurricane Harvey, Common Dreams reported on Tuesday, and local reporters are warning that it is unclear what impact the fumes from Thursday\u0026#039;s explosion and its aftermath will have on the population.\u0022Now the thing\u0026#039;s exploded, and people don\u0026#039;t know what\u0026#039;s seeping into their air and their homes,\u0022 wrote Houston Chronicle reporter Lydia DePillis\u0026rlm;.
