Safety is Our ValueSafety is Our Value
“We measure safety performance by the number
of incidents. But let’s be clear…
it’s really not about incident rates…it’s about people.
People who have faces, names, families, hopes, and dreams.”

What is What is Valley FeverValley Fever??
Disease caused by a fungus (Coccidioides or “cocci”)
Infection may occur when spores are inhaled
Fungus can infect the lungs and other parts of the body
Acute respiratory infection may occur 7 to 21 days after exposure and typically resolves rapidly
Small chance infection may alternatively result in a chronic pulmonary condition or spread to other parts of the body
Slide 5Bechtel Environmental, Safety, and Health (BESH)
Where the cocci fungus livesWhere the cocci fungus lives
Cocci lives in soil in the southwestern U.S., regions of Mexico, Central and South America
– Cocci lives in the soils of San Luis Obispo County
Cocci grows in soil to depth of inches to a few feet (needs oxygen)
Cocci fungal spores enter air when soil is disturbed by winds, construction, farming, other activities
