Safety and Health Plan <br />Tracy Ridge Tracy, California <br />March 27, 2019 Terracon Project No. NA187052.1 lierracon <br />working surfaces shall continually be inspected and maintained to be free of slip, trip, and <br />fall hazards. Keep platforms, stairs, and immediate work areas clear. Do not allow oil, <br />grease, or excessive mud to accumulate in these areas. Eliminate slip, trip, and fall <br />hazards or identify them clearly with caution tape, barricades, or equivalent means. Store <br />loose or light material and debris in designated areas or containers. Secure tools, <br />materials, and equipment subject to displacement or falling. <br />Traffic Control - If site activities interrupt the normal flow of pedestrian or vehicular traffic, <br />barricades and warning signs which comply with the Manual on Uniform Traffic Control <br />Devices and/or State or local ordinances will be erected around affected equipment. <br />Safety orange work vests will be worn by personnel working within 10 feet of any active <br />roadway. All borings or partially completed groundwater monitoring wells will be <br />adequately covered and/or barricaded if left unattended for any period of time. <br />Confined Spaces — No work will be conducted within confined spaces without discussion <br />with the Corporate Safety and Health Manager and development of a confined space <br />safety plan and permit. <br />9.0 Biological Hazards <br />Biological hazards may include ticks, fleas, mosquitoes, wasps, spiders or other pests. <br />West Nile virus is primarily spread through the bite of an infected mosquito (usually a Culex <br />species). Mosquitoes pick up the virus when they feed on infected birds. The virus must then <br />circulate in the mosquito for a few days before they are capable of transmitting the infection to <br />animals or humans while biting. The virus is found in the salivary gland of the mosquito. During <br />feeding, the virus may be injected into a human or animal where it may multiply and possibly <br />cause disease. <br />Most persons who are infected with West Nile virus will have no noticeable symptoms, or have <br />an illness syndrome called "West Nile Fever" lasting 2-10 days. Common symptoms of West Nile <br />Fever include headache, fever, and extreme muscle weakness, occasionally accompanied by <br />vomiting or skin rashes. In some cases, West Nile virus infection will cause severe neurologic <br />disease such as meningitis, paralysis, or encephalitis (swelling and inflammation of the brain). <br />Symptoms of West Nile meningitis or encephalitis may be intense headache, dizziness, stiff neck, <br />marked weakness, muscle tremors, disorientation, mental confusion, or convulsions. <br />Workers should protect themselves from mosquito bites by applying insect repellent to exposed <br />skin. Generally, the more active ingredient a repellent contains, the longer it can protect from <br />mosquito bites. A higher percentage of active ingredient in a repellent does not mean that <br />protection is better—just that it will last longer. Choose a repellent that provides protection for the <br />amount of time that you will be outdoors. Repellents may irritate the eyes and mouth. Whenever <br />10
