In 2021, the Asunción Valdivia Heat Illness and Fatality Prevention Act was introduced in the US House of Representatives. The main purpose of the legislation, named after a California farmworker who died of heatstroke in 2004 after picking grapes for ten straight hours on a 105-degree day, is to finally require OSHA to develop heat rules. As I write this in 2023, the chances that the legislation will make it to the House floor for a vote anytime soon are virtually zero.
