First aid is extremely important when someone is exposed to waters potentially contaminated with human, animal, or toxic wastes.
If you live in a hurricane-prone area, take a community-based first aid course, such as those offered by the American Red Cross.
If you are injured, contact a physician if possible to determine the necessary type of treatment (for example, need for tetanus shot).
Immediately clean out all open wounds and cuts with soap and clean water.
Apply an antibiotic ointment to wounds and cuts if available to discourage infection. Take care to assure the affected individual is not allergic to the compound.
If a wound develops redness, swelling, or drainage, seek immediate medical attention.
If you are not sure what to do for yourself or someone else, seek help immediately.
