Health and Safety Plan for Delineation and Destruction of Well B-1 Valley Fever Valley fever, or coccidioidomycosis, is an infection caused by the fungus Coccidioides immitis. Valley fever can be contracted by breathing in the microscopic fungal spores when they become airborne. The fungus is known to live in the soil in the southwestern United States and parts of Mexico and Central and South America. Most people who breathe in the spores do not get sick, and usually, people who get sick with valley fever will get better on their own within weeks to months, but some people will need antifungal medication. Certain groups of people — including adults aged 60 or older, people who have weakened immune systems, pregnant women, and people who have diabetes are at higher risk for developing the severe forms of the infection. Avoid Valley Fever by wearing dust masks when working in areas with large amounts of dust. Poison Ivy/Poison Oak/Poison Sumac Be aware of plants in the work site. Poison ivy has three pointed leaves that change colors with the seasons; reddish in the spring, green in the summer, and yellow, orange or red in the fall. Poison oak has three leaves shaped in lobes that resemble leaves of an oak tree. Poison sumac has leaves that grow in groups of 7 to 13 along the stems. The plant itself resembles a shrub or a tree with clusters of small, yellowish flowers that mature into clusters of yellow or off-white berries. If these poisonous plants are known to grow in the area of a work site, cover up with closed shoes, long pants and long sleeves. If you come into contact with any of these plants,wash clothes and skin that have been exposed with soap and warm water. Be sure to scrub under nails. The rash can spread if the oils are present when scratching. Tecnu®or alcohol wipes can be used to remove the oils. 3.4.2 Weather Sunburn Working outdoors with the skin unprotected for extended periods of time can cause sunburn. Excessive exposure to sunlight is associated with the development of skin cancer. Field staff personnel should take precautions to prevent sunburn by using sunscreen lotion and/or wearing hats and long-sleeved shirts. Sunscreen is recommended to have a minimum of sun protection factor(SPF) 30. Heat Stress Adverse climate conditions are an important consideration in planning and conducting site operations.
