In your demonstration, explainhow dishes and utensils should be washed, dried,and kept sanitary at home and in camp.

Requirement 3 Contaminated water can transmit diseasessuch as cholera, dysentery, typhoid, andpolio, and is estimated to cause 485,000diarrheal deaths in the world each year. Over the last 100 years, manyimprovements in the health, success, andlifespan of the U.S. population can belinked to improvements in water quality. Water treatment and disinfection was oneof the most important public healthachievements in the U.S. of the 20thcentury and have helped ensure access tohealthy and safe water for millions ofAmericans.

Requirement 3

Requirement 3 The water in lakes, rivers, and springs maylook crystal clear but often contains variousbacteria that can cause illness. Three purification methods:– Filters: Simply pump water from the sourcewith a water filter into a container. The filtermechanically removes protozoa and bacteria.– Chemical tablets: Water purification tablets,such as Potable Aqua, are a second option.They employ chemicals, usually iodine, to killharmful bacteria.– Boiling: Bringing water to a rolling boil is athird option.

Requirement 3Washing Dishes While Camping Prewash: Is for getting the waste off ofthe dishes.Hot Water Wash: Using as little soap aspossible, the dishes are washed. Thecleanest dishes go first, the dirtiestdishes go last.Hot Water Rinse: Rinse dishes in hotwater.Sanitizing Soak: dip dishes in a chlorineand water rinse to kill bacteria. Use 1tablespoon of bleach to 1 gallon ofwater for your rinse. Allow utensils toremain for 45 seconds in the rinse.The utensils should be air dried andthen covered or put away once dry.

Requirement 3How NOT to wash dishes while camping!!

Requirement 3Washing Dishes at Home Step One: Scrape food off surfaces before washing. Step Two: Wash the dishes in hot, soapy water. Be sure to use cleandishcloths each day and don’t use sponges! They tend to harborgerms. Step Three: Rinse dishes very thoroughly in clean, hot water. Youwant all the soap removed because soap that makes its way into yourchlorine bleach solution in Step 4 stops the bleach from sanitizing. Step Four: Sanitize the dishes with a chlorine bleach solution. Soakdishes for at least 45 seconds in a sanitizing solution made up of 1tablespoon of unscented chlorine bleach 1 gallon of cool water. Step Five: Allow dishes to air dry. Don’t dry with a cloth or towel; thiscan spread germs.

Requirement 44.Explain what a vector is and how insects and rodentscan be controlled in your home, in your community,and at camp. Tell why this is important. In yourdiscussion, explain which vectors can be easilycontrolled by individuals and which ones requirelong-term, collective action.

Requirement 4 A disease vector is an organism that does not cause a disease, buttransmits an infection by conveying pathogens from one host toanother, serving as a route of transmission.

Requirement 4Vector control focuses on utilizing preventive methods tocontrol or eliminate vector populations. Commonpreventive measures are: Habitat and environmental control– Removing or reducing areas where vectors can easily breedcan help limit their growth. Both individuals and communities can undertake stagnantwater removal, destruction of old tires and cans which serveas mosquito breeding environment. Both individuals and communities can reduce the presenceof garbage to reduce the incidence of flies and rodents actingas vectors to spread diseases. Both individuals and communities can reduce the presenceof human/animal (pet) feces to reduce the incidence of fliesacting as vectors to spread diseases.

Requirement 4Vector control focuses on utilizing preventive methods tocontrol or eliminate vector populations. Commonpreventive measures are: Reducing contact– Limiting exposure to insects or animals that are knowndisease vectors can reduce the likelihood of contact withvectors reducing infection risks significantly. The individual can use screens on homes or tents andwear protective clothing when outside, to reduce thelikelihood of contact with insect vectors. Eliminate entry points that rodents can use to enter thehome.

Requirement 4Vector control focuses on utilizing preventive methods tocontrol or eliminate vector populations. Commonpreventive measures are: Chemical control– Larvicides can be used in mosquito breeding zones throughcommunity programs.– Insecticides can be applied both around the home and community.– Individuals using insect repellents can reduce insect and tick bitesand thus infection.– Both individuals and communities can use rodenticides (rat poison)to control mice and rats. Biological control– The use of natural vector predators by government agencies canhelp control vector populations. Using fish that eat mosquito larvae,.
