Hundreds of Texans reportedly sustained carbon monoxide poisoning as a result of the power outages caused by Hurricane Beryl last month.

The fallout from the hurricane resembled that seen during Winter Storm Uri in 2021 when many people used portable generators to heat up their homes. However, this time around, residents in the Houston area were trying to keep cool down amid the sweltering Texas heat.

Here’s some of what The Texas Tribune and ProPublica reported on some of the people who were injured by carbon monoxide poisoning in the days following the hurricane in July:

Though generators have been linked to deaths after nearly every major power outage, including 10 fatalities in Texas during the 2021 winter storm and power grid failure, Wells was not worried.

Her family had routinely used the generator when the power was out, including during the 2021 freeze, which resulted in the worst carbon monoxide poisoning event in recent history. They always kept the device at a safe distance to prevent the colorless, odorless gas from seeping inside. On July 11, however, they moved it a few feet closer to their home in Cleveland, Texas, placing it under the porch in anticipation of rain from the hurricane.
