Common Summer Workplace Hazards in the Inland Empire

Each summer, the Inland Empire—home to bustling cities like Riverside and San Bernardino—faces a sharp rise in temperatures, often pushing well past 100°F. While these months might signal beach days and barbecues for some, they also bring serious risks for the region’s labor force, especially those working outdoors or in hot, poorly ventilated environments.

From construction crews and agricultural laborers to delivery drivers and warehouse workers, the Inland Empire’s summer workforce faces unique challenges. Long hours in the sun, limited access to shade, and heat-intensified workspaces can all contribute to increased injury risks—some of which can be life-threatening if not properly addressed.

Heat-Related Illnesses

During the Inland Empire’s sweltering summer months, heat-related illnesses become a top concern for workers exposed to high temperatures. Two of the most serious conditions—heat exhaustion and heatstroke—can escalate quickly and pose significant health risks if not treated immediately.

Heat exhaustion occurs when the body loses too much water and salt through sweat. Symptoms include heavy sweating, dizziness, nausea, headaches, and muscle cramps. Left untreated, it can progress to heatstroke, a medical emergency marked by confusion, fainting, a rapid heartbeat, and dangerously high body temperature (above 104°F). Heatstroke can cause permanent organ damage or even death.

These illnesses aren’t just physical threats—they’re workplace hazards that employers are legally required to prevent.

High-Risk Jobs in the Inland Empire

Certain jobs are especially vulnerable to heat-related illnesses, particularly those that involve outdoor labor or enclosed spaces with poor ventilation. Common high-risk occupations in Riverside and San Bernardino counties include:

  • Construction workers exposed to direct sunlight on rooftops, roadways, or job sites.
  • Agricultural laborers harvesting crops in open fields with little shade.
  • Landscapers who perform strenuous work on sun-baked properties.
  • Warehouse and factory workers, especially in facilities without air conditioning.

Cal/OSHA Requirements for Heat Illness Prevention

California has strict rules in place to protect workers from excessive heat. Under Cal/OSHA’s Heat Illness Prevention Standard (Title 8, Section 3395), employers must provide:

  • Access to clean, cool drinking water—at least one quart per hour per employee.
  • Shade for rest periods, especially when temperatures exceed 80°F.
  • Regular breaks and cool-down periods, particularly in extreme heat.
  • Training on recognizing and responding to signs of heat illness.

Failure to follow these rules not only endangers workers—it opens employers up to liability and regulatory penalties.

Workers’ Compensation for Heat-Related Illnesses

If you’ve suffered from heat exhaustion or heatstroke while working, you may be eligible for workers’ compensation benefits. These benefits can cover:

  • Medical treatment and hospital bills
  • Lost wages during your recovery
  • Disability payments if the illness causes long-term effects

You don’t need to prove employer negligence—only that the illness happened while performing your job duties.

Dehydration and Fatigue

As temperatures rise in the Inland Empire, so does the risk of dehydration and fatigue—two often-overlooked contributors to serious workplace injuries. In hot environments, the body loses fluids rapidly through sweat, and if not replenished, dehydration sets in. Dehydration doesn’t just make you thirsty—it impairs physical function, slows reaction time, and clouds judgment.

When paired with long hours and physically demanding tasks, this can lead to fatigue, increasing the chances of slips, falls, and accidents involving machinery or tools. Even highly experienced workers can make dangerous mistakes when they’re overheated and exhausted.

Hydration and Break Policies Are More Than Just Guidelines

To counteract these dangers, employers are legally and ethically obligated to implement hydration policies and scheduled cool-down breaks. These safety measures aren't optional—they’re required under California’s Cal/OSHA heat illness prevention rules.

Employers should provide:

  • Easy access to cool, clean water throughout the shift.
  • Rest periods in shaded or air-conditioned areas.
  • Clear work-rest cycles for high-heat conditions.
  • Training to help workers recognize the early signs of dehydration and fatigue.

Unfortunately, not all employers comply, and many workers are expected to “tough it out” or skip breaks to stay on schedule. This can lead to preventable injuries—and potential employer liability.

Recognizing Heat-Induced Fatigue on the Job

Fatigue caused by heat and dehydration often starts subtly but can quickly escalate. Warning signs include:

  • Lightheadedness or dizziness
  • Muscle weakness or cramps
  • Slowed reaction time
  • Headaches or confusion
  • Lack of coordination
  • Difficulty focusing on tasks

Ignoring these symptoms can result in serious injuries—especially when operating machinery, climbing ladders, or handling heavy materials.

Sun Exposure and Skin Damage

For many outdoor workers in the Inland Empire, daily exposure to the sun isn’t just uncomfortable—it’s a serious occupational hazard. From construction crews and landscapers to road workers and delivery personnel, prolonged time under direct sunlight puts these employees at risk for a range of UV-related health issues.

While a sunburn might seem minor, the damage from repeated sun exposure adds up. Over time, workers face elevated risks of heat rash, premature aging, and even skin cancer—including aggressive forms like melanoma.

Long-Term Health Risks from Sun Exposure

The effects of daily sun exposure can become severe over time, especially without proper protective measures. Common long-term conditions linked to excessive UV exposure on the job include:

  • Severe sunburns that can blister and cause long-lasting skin sensitivity.
  • Heat rash that leads to infection or worsens other skin conditions.
  • Skin cancer, including basal cell carcinoma, squamous cell carcinoma, and melanoma—the most dangerous form.

These conditions may not show immediate symptoms but can have devastating consequences if left unaddressed.

Employers Must Take Preventive Action

Under California workplace safety laws, employers have a duty to protect their workers from known hazards—including sun exposure. Cal/OSHA recommends and in many cases requires employers to:

  • Provide wide-brimmed hats, long-sleeved shirts, or UV-protective clothing.
  • Supply sunscreen with adequate SPF and encourage its use.
  • Ensure access to shaded rest areas during high-UV periods.
  • Offer training on the risks of sun exposure and proper use of protective measures.

If your employer fails to take reasonable steps to protect you from sun damage and you become injured or ill as a result, they may be held accountable.

Slips, Trips, and Falls on Hot Surfaces

In the Inland Empire’s extreme summer heat, job sites can become hazardous in ways many don’t expect. Sun-exposed surfaces like metal walkways, rooftops, and asphalt can reach dangerously high temperatures, leading not only to discomfort but to burn injuries and falls. Workers navigating these environments without the right precautions are at risk of serious harm.

Even seemingly routine tasks—walking across a roof, lifting materials from a truck bed, or standing on a freshly paved surface—can turn dangerous when the heat causes materials to soften, warp, or become slick.

Heat-Related Surface Hazards on the Job

Hot surfaces pose a variety of unique risks, including:

  • Melted or unstable materials: Plastic coverings, rubber mats, and asphalt can become soft or slippery in extreme heat, leading to trips and falls.
  • Improper footwear: Work boots or shoes without heat-resistant soles may lose traction or break down on hot pavement.
  • Overheated metal: Touching tools, ladders, or equipment left in direct sunlight can cause burns—sometimes severe enough to require medical attention.
  • Expansion cracks: Surfaces like sidewalks and concrete slabs may shift or crack under prolonged heat exposure, creating uneven surfaces.

These conditions increase the risk of falls, fractures, sprains, and burns—especially when safety precautions aren’t followed.

Preventing Injury—and Assigning Responsibility

Employers and property owners are legally required to identify and mitigate foreseeable hazards. That includes heat-induced surface risks. Preventive measures may include:

  • Replacing heat-sensitive flooring or walking surfaces.
  • Providing heat-resistant or anti-slip footwear as PPE.
  • Scheduling tasks during cooler hours when possible.
  • Placing warning signs or temporary barriers around hot or unstable areas.

If these precautions are ignored and a worker is injured, the employer or property owner may be held liable. Workers injured due to unsafe surfaces may be eligible for workers’ compensation—and in some cases, additional legal remedies under premises liability or negligence laws.

Know Your Rights and Stay Safe This Summer

Working through the summer in the Inland Empire means facing more than just high temperatures—it means dealing with serious, often preventable workplace hazards. From heatstroke and dehydration to slips on overheated surfaces and sun exposure injuries, the risks are real and can be life-changing.

But as a California worker, you have rights. Employers are legally obligated to follow state-mandated safety standards, especially during the summer months.
