6. 1r gad 3.6 Biological Hazards Type(s)/Source: Biting insects(mosquitoes wasps, bees&ticks)and animals. Qualified Exposure Risk: Low ` Primary"Control': • Isolation(Attention to detail—avoidance) ` • PPE(Gloves/boots/long-sleeve shirts) • Insect repellent, barrier cremes,wasp spray ` Hazard: Contact with plants, insects, and animals likely to be present at the site should be avoided. Stinging and biting insects, including bees, spiders, and ticks, can cause extreme discomfort and/or serious allergic responses. Insect bites are generilly not dangerous, unless they are from a poisonous insect or mosquitoes potentially carrying West Nile virus. The primary concern with animal bites and scratches is the potential for infection and/or rabies. Snake or scorpion bites can also be dangerous, but more from infection or trauma than the toxins injected by the snake or scorpion. Controls : Avoid conducting site activities fro dusk to dawn when the risk of encountering biting mosquitoes is higher. Before beginning fieldwor each day, inspect the work area for the presence of standing water, poisonous plants and inhabitant ptiles and take measures necessary to minimize the potential for contact. Specially prepared insect repellent containing approximately 50% DEET for protecting exposed skin from biting insects. T ese products are commercially available and may minimize the potential for development of skin i ashes and/or irritations due to such exposures; apply insect repellent sparingly to exposed skin. Note: Avoid contacting plastic zippers or other plastic closure mechanisms on clothing, equipment bags, etc.,with DEET containing creme which will cause these materials to degrade. If you are allergic to bee or wasp stings, be sure to have the appropriate first aid available (e.g., an epi- pen)on the project. If you are stung,administer first aid and seek immediate medical attention. Be sure a reptile or animal bite victim obtains inedical attention quickly if a bite or scratch occurs, ` especially if there is a potential that it was poisonous. In the meantime, administer First Aid by gently cleansing the wound with soap and water, and jinsing thoroughly under running water. Dry off and place a clean bandage on the wound. Victims c f these bites should lie down and remain calm and motionless;cold packs should be applied and trier ical attention sought immediately.
