3: Hazard Analysis Health and Safety Plan <br />3.5.4 Mosquitoes <br />Mosquitoes may transmit diseases such as West Nile Virus. Symptoms of West Nile Virus include: <br />fever, headache, tiredness, body aches, and occasional rash. Avoid mosquito bites by wearing long <br />sleeved shirt and long pants. Apply insect repellent to clothes and/or skin (if FDA approved for <br />topical use). Report any dead birds in the area to local health officials. Mosquitoes are most active <br />from dusk to dawn. <br />3.5.5 Spiders/Scorpions <br />The black widow and brown recluse spiders are the most venomous. Avoid contact with spiders and <br />scorpions and areas where they may hide. They favor dark hiding places. Inspect clothing and <br />shoes before getting dressed. Wear gloves and safety shoes when working with lumbar, rocks, <br />inspecting buildings, etc. Signs and symptoms of bites include: headache, cramping pain/muscle <br />rigidity, rash and/or itching, nausea, dizziness, vomiting, weakness or paralysis, and convulsions or <br />shock. Wash bite area with soap and water and apply antibiotic cream. Contact emergency medical <br />services if allergic reaction or severe symptoms occur. <br />3.5.6 Ticks <br />Deer ticks may carry and transmit Lyme disease to humans. Signs of Lyme disease include a reddish <br />"bulls-eye" around the affected area approximately a week after the bite. Symptoms include <br />headache, fever, and muscle/joint pain. Persons suspecting infection should contact a health <br />professional. Whenever possible avoid areas likely to be infested with ticks during the spring and <br />summer months. <br />Wear light-colored clothing so ticks can be easily spotted and removed. Wear long sleeves and pants <br />and tuck pant legs into boots or socks. Apply insect repellents to clothing and skin (if FDA <br />approved for topical application). Persons with long hair should tie their hair back to minimize the <br />potential for ticks to nestle in the scalp. <br />Personnel should self perform tick checks once daily field work is completed. If a tick is embedded <br />in the skin, use tweezers to grasp the tick's head (near the skin) and pull straight out. Consider <br />saving the removed tick for laboratory analysis. <br />3.5.7 Poisonous Plants <br />Common examples include poison ivy, poison oak and poison sumac. Avoid contact. Long-sleeved <br />shirts and pants will allow some protection against inadvertent contact. If contact occurs, <br />immediately wash the affected area thoroughly with soap and water. If an allergic reaction occurs, <br />seek the care of a medical professional. <br />Poison Ivy is a trailing or climbing woody vine or a shrub like plant with leaves that are each divided <br />into three broad, pointed leaflets. The leaflets are commonly dark glossy green on top and slightly <br />hairy underneath. They produce small yellowish or greenish flowers followed by berry-like drupes. <br />Poison Oak is a member of the same family as poison ivy and has a very similar appearance. Poison <br />oak has leaves divided into three leaflets and generally have three to seven distinct lobes. Typically <br />BROWN AND CALDWELL <br />3-15
