The state is urging residents to take care of their physical and mental health in the wake of Tropical Storm Olivia.

The Department of Health is advising the public, particularly children, to avoid floodwaters and storm runoff due to overflowing cesspools, sewer systems and manholes that may contain pesticides, dead animals, fecal matter, pathogens, chemicals and other flood debris. Brown water advisories have been issued for Maui and Lanai, and parts of Kauai, Oahu and Hawaii island. Advisories can be found at 808ne.ws/2FPj9S9.

“If people must enter brown water along coastlines or in areas where water has pooled due to flooding, take precautions to cover any open wounds or injuries, and be sure to wash and rinse thoroughly with soap and clean water afterward,” the DOH said.

The Health Department also is warning that power outages caused by severe weather may affect the safety of food. Refrigerated food is safe for up to four hours in a power outage, but residents should discard perishable food that has been above 40 degrees for more than two hours to prevent food-borne illnesses, the department said. Produce should be thoroughly washed and food should be stored in sealed containers.

The DOH is reminding the public to wash hands often to prevent the spread of illnesses and food contamination. Alcohol- based hand sanitizers are an option if soap and clean water are unavailable.

Taking care of emotional and mental health under stressful conditions is important during natural disasters, and it is critical to have a strong support system, take periodic breaks and ask for help if needed, the DOH said.

“Help your children by sharing age-appropriate information and set a good example by taking care of yourself,” DOH said. “Take breaks and unwind periodically.”

DOH’s Crisis Line of Hawaii is available 24 hours a day at 832-3100 on Oahu and 800-753-6879 on the neighbor islands.
