The state corrections department owes a federal judge a plan for lowering heat levels on Louisiana's death row.
U.S. District Judge Brian Jackson ruled in December that death row gets so hot it violates U.S. constitutional protections against cruel and unusual punishment. He demanded a plan by Monday evening that will cool the cells so the heat index never goes above 88 degrees.
Windows and fans are currently the primary sources of ventilation on death row.
Lawyers for condemned killers Elzie Ball, Nathaniel Code and James Magee say the heat could worsen the men's health conditions.
Prison officials said the conditions might be uncomfortable during the hottest summer months, but they are safe.
The corrections department is appealing Jackson's ruling, but hasn't gotten a delay in filing the cooling plan.
