California has recognized the growing danger of heat-related illnesses in indoor workplaces, where temperatures can become dangerously high, especially during the summer. Between 2010 and 2017, at least seven workers in such environments died from heat-related causes, highlighting the need for better protections. These workers often labor in settings like indoor car washes and warehouses, which can become hotter than the outside environment, posing serious health risks.

Despite the significant risks posed by indoor heat, much of the state's focus has historically been on protecting outdoor workers, such as those in agriculture. Ali Frazzini from the Los Angeles County Chief Sustainability Office pointed out that indoor workers are also at significant risk, particularly in facilities lacking air conditioning such as warehouses. 

In response to these concerns, California has now established new standards to safeguard indoor workers. These standards include providing access to cool-down areas, cold water, and other protective measures to ensure that workers remain safe as temperatures rise due to global warming. These regulations mark a critical step in expanding worker protections beyond outdoor settings.
