SPECIAL REPORT: Texas was hit by the biggest carbon monoxide catastrophe in recent U.S. history during February's storm.

Many poisoning victims had no CO alarms in their homes — Texas is one of the few states that don't require them.

At least 11 deaths have been confirmed and more than 1,400 people sought care at emergency rooms and urgent care clinics for carbon monoxide poisoning during the weeklong Texas outage in February. Children made up 42% of the cases.

Black, Hispanic and Asian Texans suffered a disproportionate share of the carbon monoxide poisonings, @propublica, @TexasTribune and @NBCNews found based on a review of hospital data. They accounted for 72% of the poisonings, far more than their 57% share of Texas' population.

Over the past two decades, the vast majority of states have implemented laws or regulations requiring carbon monoxide alarms in private residences, often on the heels of high-profile deaths or mass poisonings during storms.

But in Texas, where top lawmakers often promote personal responsibility over state mandates, efforts to pass similar carbon monoxide requirements have repeatedly failed.
