As the location of job sites change the environment changes with them. In the Central Valley of California one of the hazards we deal with is a fungus that can live within the soil. When the soil is disturbed by digging, vehicles, or wind, the fungus spores get into the air and when they reach the lungs it can cause the illness known as Valley Fever. Reactions to the illness can vary by individual and it is not a contagious disease, but workers can face symptoms such as fatigue, cough, fever, and difficulty breathing among others. We prevent Valley Fever exposure by using water on open dirt areas to keep dust down, avoid work during dust storms, and using water to clean dusty equipment.
