Mold Exposure at Work: What Colorado Employees Need to Know in 2025

Aug 22, 2014 | WC & Other Laws

Mold may be out of sight, but it should never be out of mind—especially when it comes to workplace safety. Exposure to mold in the workplace can lead to serious health issues, and many workers don’t even realize they’ve been exposed until symptoms become persistent or severe.

If you’re experiencing unexplained respiratory issues, chronic fatigue, or allergy-like symptoms at work, mold could be the hidden cause—and you may be entitled to workers’ compensation benefits.

What Is Mold and Why Is It Harmful?

Mold is a type of fungus that spreads by releasing spores into the air. These spores can easily become airborne—even if the mold itself is hidden behind walls, under flooring, or covered in paint. Once inhaled, mold spores can trigger allergic reactions, respiratory conditions, and in some cases, long-term health complications.

Some molds also produce mycotoxins, which are toxic substances linked to neurological symptoms, immune suppression, and chronic illness.

Common Symptoms of Workplace Mold Exposure

Because symptoms can resemble allergies or the common cold, many workers overlook early signs of mold exposure. Others may not develop symptoms until prolonged or repeated exposure.

Watch for the following symptoms:

Persistent or worsening respiratory issues (e.g. difficulty breathing, chronic cough)

  • Allergy-like symptoms (sneezing, nasal congestion, itchy eyes)
  • Recurring headaches
  • Flu-like symptoms that don’t resolve
  • Lethargy or unusual fatigue
  • Skin rashes or irritation

If multiple coworkers are experiencing similar symptoms, that’s a red flag—and it may support your claim.

What to Do If You Suspect Mold at Work

1. See a Doctor Immediately

Discuss your symptoms and potential mold exposure with your healthcare provider. There are specific medical tests that can help determine:

  • Whether you’ve been exposed to mold
  • The type and concentration of mold
  • The severity of your reaction

Early documentation is essential if you plan to pursue a workers’ compensation claim.

2. Identify the Source of Exposure

Once medical concerns are raised, the next step is to identify where the exposure occurred. Mold may be found in:

  • Air ducts or HVAC systems
  • Basements or storage areas
  • Ceilings and walls with prior water damage
  • Poorly ventilated restrooms or break rooms

Take photos, report what you see (or smell), and talk with coworkers who may be experiencing similar issues.

3. Report It to Your Supervisor—Promptly

Per CDC guidance and Colorado workplace safety protocols, you should report mold concerns to your employer as soon as possible. Keep a record of your complaint in writing.

Filing a Workers’ Compensation Claim for Mold Exposure

Occupational disease claims—especially those involving environmental exposure—can be complex, expensive, and fiercely contested. Employers and insurers may try to deny liability, especially when symptoms are gradual or affect multiple people.

That’s why it’s critical to:

  • Document your medical condition early
  • Find other affected coworkers, if possible, to strengthen your case
  • Consult an experienced workers’ compensation attorney who understands mold exposure claims

At Kaplan Morrell, we’ve helped countless workers across Colorado get the medical treatment and compensation they deserve after exposure to mold, chemicals, and other airborne contaminants in the workplace.
