Hurricane experience benefits later industrial fire research response

NIEHS-funded researchers reported that lessons from Hurricane Harvey accelerated and improved research response after an industrial fire.

In 2017, Hurricane Harvey affected more than 30,000 Texas residents and destroyed more than 200,000 homes. Following that experience, the Southwest Center for Occupational and Environmental Health (SWCOEH) teamed up with community, academic, and government partners to create a location-specific disaster research response (DR2) toolkit.

These experiences are described in a paper published March 16 by NIEHS-funded researcher Elaine Symanski, Ph.D., and her collaborators. The former director of SWCOEH, which is at The University of Texas Health Science Center (UTHSC) at Houston, Symanski is now with Baylor College of Medicine.

The new paper highlights DR2 work assessing allergic symptoms and stress, as well as safety training and distribution of personal protection kits, in the aftermath of Hurricane Harvey.

Just 18 months after the hurricane, SWCOEH used the study protocols and other resources in the new toolkit to rapidly mobilize researchers and volunteers to respond to the Intercontinental Terminals Company fire in Deer Park, Texas. The fire started March 17, 2019 and burned for six days.

“Our experience illustrates the potential positive impact of a coordinated and collaborative response to the environmental consequences of disasters, and how one experience informs capacity among all partners in future DR2 responses,” Symanski said.

The National Institutes of Health (NIH) DR2 program, led by NIEHS, contributed to development of the Houston-area DR2 toolkit through publicly available resources such as the Rapid Acquisition of Pre- and Post-Incident Disaster Data (RAPIDD) protocol. Use of the RAPIDD protocol has helped researchers shorten the time needed to begin collecting health data, medical tests, and biological samples from people exposed to environmental contaminants.

Bringing science to the scene

Richard Kwok, Ph.D., a staff scientist in the NIEHS Epidemiology Branch, serves as the institute’s DR2 program manager. He explained that although the middle of a disaster may seem an inappropriate time to conduct research, there are good reasons why that timing is incredibly important, and development of DR2 toolkits is essential.

“In the midst of a typical disaster response, the primary focus is on immediate needs — saving lives and preventing property and environmental damage,” Kwok said.

“Because of this, health concerns repeatedly go unidentified and unaddressed. The DR2 program is helping enable research that otherwise would be missed,” he continued. “We can’t improve our responses, or our ability to recover and better prepare for future events without the critical information provided by timely data collection and research.”

Environmental justice matters

Symanski noted that communities of color are more likely to experience greater impacts of disasters, due to vulnerabilities like poor housing and limited access to a host of resources. Therefore, DR2 toolkits need to address environmental justice.

“Addressing environmental justice concerns requires a trusted partnership between academics and community members,” she said. “There is a need for greater recognition and allocation of resources among [research] funders to support long-term activities required for establishing these partnerships.”

She further explained that lots of communities may be disproportionately affected by disasters, so researchers need an expanded network of partnerships to conduct community-engaged research.

“This circles back to the need for resources to establish and maintain partnerships that can be leveraged when disasters hit,” Symanski said.

From local to global impact

The NIH DR2 program resources are seeing usage beyond local applications (see sidebar). “In April 2020, NIEHS, in collaboration with the National Library of Medicine, mobilized staff and contractors to quickly transform the DR2 platform to support the National Institutes of Health (NIH) COVID-19 response,” said Aubrey Miller, M.D., NIEHS senior medical advisor and NIH DR2 program director. “To date, over 125 COVID-19 data collection tools have been submitted to the DR2 platform by research groups around the world.”

Miller said that the DR2 team will launch a new web portal this summer, with improvements and updates, including keyword search capabilities, availability of common data elements, surveys to enhance electronic data capture, and links to other widely used data repositories.
