With more heat waves expected this summer, California officials are trying to assess the long-term economic impact on workers and businesses — and what more can be done to protect workers bearing the brunt of extreme temperatures.
Although California is one of the few states with heat standards protecting outdoor workers, advocates and workers say enforcement is still a struggle. Meanwhile the state has been trying for years to create indoor workplace heat rules.
A 2021 study of California worker compensation data by a left-leaning economic research nonprofit shows hot days lead to increased workplace accidents across California. The Washington Center for Equitable Growth study estimates hot temperatures have caused at least 360,000 workplace injuries in California from 2001 to 2018, or about 20,000 injuries a year.
The welfare impacts associated with heat-related workplace injuries may be on the order of $525 million to $875 million per year in California.
Researchers examined California workers compensation data and tracked daily temperatures down to the zip code. They compared the number of worker injuries and illnesses on 85-to-105-degree days to days when temperatures hovered around 60 degrees.
A new state advisory committee is set to use this data as a roadmap to tackle hot workplace issues. The group of state agency staffers and scholars will examine persistent problems with underreported heat-related illness and injuries, as well as gaps in data collection and the financial toll on workers and businesses when temperatures rise and production falls.
Young workers at risk
A day above 100 degrees can lead to a 10-15% increase in same-day injuries on the job, the study says, with injuries hitting low-wage workers hardest. And recovering from a heat-related injury or illness costs the average worker $35,000, including health care and long-term wage impact.
“This implies that the welfare impacts associated with heat-related workplace injuries may be on the order of $525 million to $875 million per year in California alone,” the study authors wrote.
The study says workplace injuries include incidents not usually linked to heat, such as falling from heights, getting struck by a vehicle or mishandling dangerous machinery. Research links high temperatures to reduced cognitive performance and decision-making.
The lead author of the study, University of Pennsylvania professor R. Jisung Park, is a member of the advisor committee. He and his coauthors found that low-wage workers, especially young men, face the greatest risks of heat injuries, even in mostly-indoor workplaces like restaurants or warehouses.https://datawrapper.dwcdn.net/GKazD/3/
The state’s advisory committee met for the first time at the end of June. Its mandate is part of a package of heat-related legislation passed last year.
Gov. Gavin Newsom in September signed several bills creating the first extreme heat warning and ranking system in the nation, directing the California Department of Public Health to study the impact of extreme heat on pregnant workers and encouraging local governments to invest in protections against extreme heat and other climate effects.
“There are certain sectors that are going to be heavily influenced of course, including food production,” said Daniel Sumner, an advisory committee member who is an agricultural and labor economist at UC Davis. “I think we’d be remiss not to try to think through impacts that directly affect workers’ lower productivity, raise danger for workers, and as a consequence raise food prices.”
Are California workers protected from heat?
California is one of a few states with laws that mandate employers provide water breaks, shade and rest for outdoor workers once temperatures reach certain levels.
The state implemented its outdoor heat standard in 2005, after several farmworkers – three in Kern County and one in Fresno County – died due to heat exposure. After the 2008 death of a pregnant teen working in a Central Valley vineyard drew national outrage, state officials frantically tried to strengthen and enforce the heat protections.
The Washington Center study found occupational heat-related injuries in California declined by about 30 percent since the standards took effect in 2005.
There still are no heat-related federal workplace protections, even for outdoor workers, although the Occupational Health and Safety Administration announced two years ago it was developing heat rules for outdoor and indoor workers.
There’s currently little relief for California’s indoor workers. The state has been considering proposals for heat rules for employees in indoor settings like restaurants or warehouses for nearly seven years, missing a 2019 deadline the Legislature set.
Last summer, a 24-year-old United Parcel Service driver died after collapsing from the heat during deliveries in Pasadena.
The 340,000-strong union representing the UPS workers has been seeking heat rules that would cover its California members. The union reached a “historic” contract agreement with the company July 25 after threatening a strike, securing a deal with higher wages and more heat protections.
Jassy Grewal, a lobbyist for the United Food and Commercial Workers Western States Council and a member of the state’s heat advisory committee, said workers in high-intensity environments, or those who don’t have a cool place at home, are especially vulnerable without indoor heat rules.
“What type of pressures from employers, like work quotas, contribute to heat-related illness,” Grewal asked during the first committee meeting. “And how does the intensity of work and how physically demanding it is relate to the impact of heat exposure while at work and while not at work?”
Gaps in job protections
Unions and worker advocates have sued the state in the past to enforce heat-related regulations, and they say the state needs to hold employers accountable.
Advocacy groups warn that despite progress, the greatest risk to workers lies with the state’s troubled enforcement record.
Some experts say it’s as simple as better outreach, informing workers about heat risks and their rights.
“It’s all implementation and ensuring that these workers actually get the benefits of these laws,” said Michael Méndez, environmental policy professor at UC Irvine, “and having a culturally and linguistically appropriate messaging on the risk and severity of these heat waves.
“I think for any population it’s confusing to understand how our climate is changing and how much risk they could have. So ensuring that we have trusted messengers and doing it in a culturally and linguistically appropriate way matters.”
“We expect state agencies to be out in full strength across California to make sure employers are being compliant with the state heat rules. Heat is still a deadly hazard.”ANTONIO DE LOERA-BRUST, UFW SPOKESPERSON
The United Farm Workers sued the Cal/OSHA in 2012 to compel the state to enforce heat rules for farmworkers. In 2015 the state settled a suit the union brought on behalf of five farmworkers who alleged CalOSHA was systematically neglecting its duty to enforce the 2005 law.
UFW spokesperson Antonio de Loera-Brust told CalMatters “people died to win” California’s enforcement standards.
“We expect state agencies to be out in full strength across California to make sure employers are being compliant with the state heat rules,” De Loera-Brust said. “Heat is still a deadly hazard.”
Farmworker health
A February study on California farmworker health and safety by the UC Merced Community and Labor Center found that only a third of farm laborers could recognize the symptoms of a heat-related illness.
Only half of the roughly 1,500 farmworkers surveyed said their employers always provide shade mandated by California law when it hits 80 degrees, while a quarter said their employers never or rarely provide the required shade.
The study, which surveyed farmworkers in six languages, also found:
- About 22% of farmworkers said their employer “never” monitors for heat illness. A slightly higher percentage in the Imperial Valley, where scorching temperatures are common, said the same.
- 82% of farmworkers in the San Joaquin Valley said they have received heat related illness training.
- About 43% of farmworkers statewide, including two-thirds of Central Coast farmworkers, said their employers never had a written heat illness protection plan.
Some farm employers still don’t comply with state rules about providing water, shade and rest, the survey shows.
- 55% of farmworkers across the state said their employers always monitored the temperature on hot days — 76% said it in the Imperial Valley, but 46% did in Napa Valley and Sonoma areas.
- 75% of farmworkers said their employers provide clean drinking water every time.
- Barely half of farmworkers reported their employers always provide a 10-minute cool down rest, while 21% said their employers “never” did.
Alice Berliner, worker health and safety program director at the community and labor center, said it’s clear employers some workers aren’t getting safety information or training in Spanish when they need it.
“We know heat-related deaths are going up,” she said. “If we want to prevent future deaths from happening, we really need to ensure workers are protected at work.”
State officials taking preventive measures, such as conducting heat sweeps ahead of heat waves, has helped, she added.
What will the state committee do?
Assembly Speaker Robert Rivas, who authored legislation creating the advisory committee last year, called the panel of 13 a “solid first step.” He said he will work with the Legislature to do more for workers.
“Climate change is accelerating, and extreme heat and heat-related illnesses are on the rise,” the Salinas Democrat said in a statement. “California is committed to protecting workers’ health and quality of life during extreme heat waves.”
Despite near-universal consensus among state officials and advocates that heat reform work is urgent, and despite recent record shattering temperatures, the committee has been given a 2026 deadline to report results to the Legislature.
The committee is set to meet quarterly. The next session is September 19. Members indicated they’ll likely commission a study to guide the committee’s work.
“I have no doubt the work this committee will do will save lives,” said Cal/OSHA chief Jeff Killip at the meeting.
Tips from the National Weather Service about heat waves:
Outdoor Activities
- Slow down. Reduce, eliminate or reschedule strenuous activities until the coolest time of the day. Those particularly vulnerable to heat such as children, infants, older adults (especially those who have preexisting diseases, take certain medications, living alone or with limited mobility), those with chronic medical conditions, and pregnant women should stay in the coolest available place, not necessarily indoors.
- Dress for summer. Wear lightweight, loose fitting, light-colored clothing to reflect heat and sunlight.
- Minimize direct exposure to the sun. Sunburn reduces your body’s ability to dissipate heat.
Eating and Drinking
- Eat light, cool, easy-to-digest foods such as fruit or salads. If you pack food, put it in a cooler or carry an ice pack. Don’t leave it sitting in the sun. Meats and dairy products can spoil quickly in hot weather.
- Drink plenty of water (not very cold), non-alcoholic and decaffeinated fluids, even if you don’t feel thirsty. If you are on a fluid-restricted diet or have a problem with fluid retention, consult a physician before increasing consumption of fluids.
- Do not take salt tablets unless specified by a physician.
Cooling Down
- Use air conditioners or spend time in air-conditioned locations such as malls and libraries.
- Use portable electric fans to exhaust hot air from rooms or draw in cooler air.
- Do not direct the flow of portable electric fans toward yourself when room temperature is hotter than 90°F. The dry blowing air will dehydrate you faster, endangering your health.
- Take a cool bath or shower.
Check on Others
- Check on older, sick, or frail people who may need help responding to the heat. Each year, dozens of children and untold numbers of pets left in parked vehicles die from hyperthermia. Keep your children, disabled adults, and pets safe during tumultuous heat waves.
- Don’t leave valuable electronic equipment, such as cell phones and GPS units, sitting in hot cars.
- Make sure rooms are well vented if you are using volatile chemicals.
Heat Safety in Vehicles
- Even on mild days in the 70s, studies have shown that the temperature inside a parked vehicle can rapidly rise to a dangerous level for children, pets and even adults. Leaving the windows slightly open does not significantly decrease the heating rate. A dark dashboard or car seat can quickly reach temperatures in the range of 180°F to over 200°F. These objects heat the adjacent air by conduction and convection and also give off long wave radiation, which then heats the air trapped inside a vehicle. Touch a child’s safety seat and safety belt before using it to ensure it’s not too hot before securing a child
- Never leave a child unattended in a vehicle, even with the windows down, even for just a minute
- Teach children not to play in, on, or around cars. They could accidentally trap themselves in a hot vehicle.
- Always lock car doors and trunks–even at home–and keep keys out of children’s reach.
- Always make sure children have left the car when you reach your destination. Don’t leave sleeping infants in the car.

As California continues to ride its worst wave of the COVID-19 pandemic, public health officials have more unsettling news: Six cases of a worrisome, potentially more infectious new coronavirus variant have been detected in California.
The new strain, first detected in the United Kingdom, also has been seen in Colorado and Florida and 33 other countries.
Last week, San Diego County reported it had identified the new variant, called B.1.1.7, in a 30-year-old man with no travel history. Gov. Gavin Newsom announced the discovery in a live streamed event with Dr. Anthony Fauci, a leading national voice in the pandemic. Over the weekend, San Diego county health officials reported three additional cases.
Fauci said this news was expected, since international travel is ongoing and viruses generally mutate. “RNA viruses, they make a living out of mutating,” he said. “The more you replicate the more you mutate.”
However, the lack of travel history in the San Diego case is an indicator that the new form of the virus is circulating among the community, health officials there said. By today, the number of cases with the new variant had grown to six – four in San Diego, with one hospitalized, and two in San Bernardino, the governor announced.
“What’s really important is that detecting this lineage here doesn’t really change what we need to do other than we need to do it better,” Dr. Kristian Andersen, an infectious disease and genomics expert at Scripps Research in San Diego, said in a news conference. That includes wearing masks and maintaining social distance.
Here’s what Californians need to know about the new coronavirus strain.
How was it discovered?
The new virus variant was first reported by England’s public health agency following a surge of cases in the southeastern part of the country. The first two samples were discovered in Kent and in London in September.
While mutations in viruses are common, this particular strain stood out because it carries more genetic changes than is typical, according to researchers.
What’s the concern with this coronavirus variant?
Public health officials say the new strain seems to be more easily transmitted than the standard form of the virus. This means people who are exposed are more likely to become infected.
According to health officials in the United Kingdom, evidence shows that infection is growing more rapidly in geographical areas where this variant is found. A study from The Centre for the Mathematical Modelling of Infectious Diseases in London shows this particular strain is 56% more transmissible. The study is still being peer-reviewed.
Dr. Mark Ghaly, California’s health secretary, explained it like this in a recent news conference: “For COVID to enter a human cell, it needs to bind to a receptor, a sort of front door on a human cell,” he said. “And the new, mutated COVID virus seems to bind a little tighter, a little more easily and enter the cell of the human body easier than our current COVID virus.”
It remains unclear how this mutant form of the virus has contributed to the current surge in California. Officials have said its prevalence here is still likely low. On Dec. 21, Ghaly said that California had been checking thousands of specimens daily over the last month, looking for mutations.
“We’re concerned because of the unknowns,” Ghaly said. “We’re concerned that we aren’t sure how this impacts the broadscale efforts to contain and mitigate the virus as it exists now.”
What is California doing in response?
The California Department of Public Health said health care providers are collecting specimens for genetic sequencing, and the state is analyzing samples suspected of being variant strains.
“As variants and mutations are found, that information is used to inform public health decisions and critical information is shared with the public,” the department said in an email.
How widespread is the new strain?
After the new variant was detected in the United Kingdom, some 40 countriesrestricted travel from the UK. The variant has since been reported in France, Japan,Spain, Sweden and Canada among other countries.
The first known U.S. case, in a Colorado National Guardsman in his 20s, was reportedDec. 30.
Two variants that share some mutations with the UK variant also have been reported in South Africa and Nigeria, according to the U.S. Centers for Disease Control and Prevention.
“We know there’s more. We don’t know how many,” said Andersen, the infectious disease expert in San Diego. “Its prevalence for now is relatively low.”
Will it make me more sick?
Right now, there’s no evidence that this new COVID variant has a higher fatality rate or causes more severe illness than the currently predominant strain, according to the CDC. A recent UK government study compared patients infected with the new variant to those with the predominant strain and found no statistically significant differences in severity of illness, deaths or reinfection. Scientists around the world are still studying the UK variant, however, and more answers may come soon.
Will currently authorized vaccines protect against this new strain?
Scientists believe they will. Fauci told Newsom last week that the variant “doesn’t seem to evade the protection that’s afforded by the antibodies that are induced by vaccines.” But scientists are testing the variant against the currently authorized vaccines made by Pfizer and Moderna.
The CEO of AstraZeneca, which is developing another COVID-19 vaccine candidate, told the London Times that the company’s scientists believe the vaccine will protect against the new variant. But some scientists believe it’s possible that the UK variant, or future variants, may prove tougher for vaccines to overcome.
