Failed presidential candidate Gov. Ron DeSantis (R) signed a bill late last week barring Florida localities from requiring employers to provide outdoor workers with access to water, rest and shade, outraging workplace safety advocates who say the new law will kill people .

Backed by the agricultural and construction industries, the controversial legislation is whats known as a preemption law: It forbids cities and counties from pursuing their own ordinances on a particular subject, in this case protections from extreme heat.

The law effectively nullifies a proposal in Miami-Dade County that would require some employers to maintain a heat safety program and provide employees with water and shade on hot days. The county commission recently withdrew the proposal after the state legislation put its legality in doubt.

The preemption bill recently passed the Republican-controlled state House and Senate, along with a similar measure that prevents jurisdictions from requiring employers to pay livable wages on government-funded projects.

Unions and other progressive groups said blocking heat regulations would endanger farm and construction workers and anyone else who labors in one of the hottest states in the country.

Someone is going to die as a result of this legislation, Kim Smith, a telecommunications technician, told HuffPost last month.

Last year, Texas Republicans passed a similar preemption bill that blocked localities from implementing heat protections as well as other ordinances related to housing and labor. The legislation, known as Texas death star bill, appeared designed to thwart local laws in Austin and Dallas that guaranteed water breaks for workers.
