Authorities on Thursday warned surrounding residents to stay indoors after high levels of benzene were detected in the air near a scorched petrochemical storage facility outside Houston.

Firefighters on Wednesday extinguished the blaze at the Intercontinental Terminals Co. in Deer Park that started Sunday and destroyed several large tanks that contained gasoline and chemicals used in nail polish remover, glues and paint thinner. They continued to spray foam on the site Thursday to try to prevent flare-ups.

Officials said Wednesday that benzene levels near the facility didn’t pose a health concern. But authorities issued an order to shelter in place Thursday due to “reports of benzene or other volatile organic compounds” in Deer Park, which is about 15 miles southeast of Houston. Several school districts also canceled classes for the day due to the air quality concerns.

Harris County Judge Lina Hidalgo, who is the county’s top administrator, said at a news conference Thursday that light winds were helping to keep the vapors from spreading more broadly.

“Outside of that immediate area we’re not seeing elevated levels right now,” said Hidalgo.

Dr. Umair Shah, who heads the county health agency, said there’s still only a minimal public health risk, but he cautioned that the elderly, pregnant women and other vulnerable groups should try to limit their exposure.

“The most important thing is that the levels that have been detected are still not high enough for the level of concern that people may be having,” he said.

The county fire marshal, Laurie Christensen, said the benzene vapors may be escaping from gaps in the foam that firefighters have been spraying to try to prevent flare-ups at the site.

The Texas National Guard was assisting at the scene Thursday. A team of about a dozen guard personnel was helping to contain hazardous materials and provide other assistance to local emergency responders.

Environmental groups said residents who live near the facility have experienced various symptoms, including headaches, nausea and nosebleeds. According to the Centers for Disease Control and Prevention, long-term exposure to benzene, a highly flammable chemical, is harmful to blood and bone marrow.

The Environmental Protection Agency conducted air quality tests throughout the Houston area, both on the ground and from a small plane, and “measured no levels of hazardous concentrations,” EPA official Adam Adams said Wednesday.

Some residents who live near the facility, though, said they didn’t have confidence in the air quality test results.

“Everything has been wrapped up in this nice perfect bow in saying that there were no problems. Every air quality was perfect. Every wind was perfect, blowing it away. And if everything was so perfect, why did it happen?” longtime Deer Park resident Terri Garcia said.

Bryan Parras, an organizer in Houston with the Sierra Club, said his environmental group had concerns not just about the air quality, but about the potential effects on the environment and the fishing industry if chemicals from the storage facility or firefighting foam get into the Houston Ship Channel, which leads to the Gulf of Mexico.

“This issue isn’t over just because the fire is out. We want systems in place that will protect our communities,” Parras said Wednesday.

The EPA and the Texas Commission on Environmental Quality said Wednesday that they were waiting for test results of water samples to determine any potential effects from the foam used to fight the fire on waterways next to the storage facility, including the Houston Ship Channel.
