Among record-breaking heat waves across much of the nation that have created dangerous conditions for workers, a group of US Senators has proposed legislation that seeks to protect workers from the heat.

According to a release from Sen. Sherrod Brown (D-OH), the bill is co-sponsored by Sens. Alex Padilla (D-CA), Catherine Cortez Masto (D-NV), and Bernie Sanders (I-VT), alongside 15 other Democratic Senators and 4 cosponsors leading the bill in the House of Representatives.

The bill, named the Asunción Valdivia Heat Stress Injury, Illness, and Fatality Prevention Act, is named in honor of Asunción Valdivia who died in 2004 after picking grapes for ten hours straight in 105-degree temperatures. Mr. Valdivia fell unconscious and instead of calling an ambulance, his employer told Mr. Valdivia’s son to drive his father home. On his way home, he died of heat stroke at the age of 53.

The bill comes in the midst of record-breaking heat waves and rising temperatures, resulting in the widely publicized death of a Dallas postal worker and allegedly another death, this time a construction worker in south Texas. Another construction worker died in Galveston county after working in excessive heat, and a farm worker in Florida also died after suffering heat stroke on the job.

According to Harvard University, increasing temperatures have caused an increase in rates of heat-related illness in recent years, creating what Brown says are "dangerous" conditions which force workers to "[put] their health and safety on the line every day to provide for their families."

“Asunción Valdivia tragically lost his life to heatstroke picking grapes in 105-degree heat under the Central Valley sun. Nearly 20 years later, millions of Americans are facing record-breaking extreme heat conditions that put the health and safety of our workers at risk,” said Senator Padilla, a Democratic Senator from California. “This critical legislation will hold employers accountable and ensure enforceable workplace protections are put in place to prevent workers from falling ill, collapsing on the job, or even losing their lives.”

The bill seeks, among other things, require employers provide "suitably cool potable water or appropriate hydration" if other personal protective equipment is not used. The measure comes amidst backlash after Texas passed a law banning mandatory water breaks.

With no GOP cosponsors, it is unclear how far the legislation will make it in either chamber.
