Underestimating the Dangers: Flood Waters Can Be Deadly

As Tropical Storm Debby approaches central Florida, the state braces for another bout of severe weather. While many Floridians are familiar with the routine of preparing for storms—stocking up on supplies, securing property, and staying informed—there's a critical aspect that often goes underestimated: the dangers of flood waters. Beyond the inconvenience of navigating submerged streets or dealing with water-damaged property, flood waters pose significant risks that can have life-threatening consequences.

Hidden Hazards Beneath the Surface

One of the most insidious dangers of flood waters is what lies beneath. Murky and opaque, flood waters can obscure sharp objects, debris, and open manholes, creating treacherous conditions for anyone wading through. In urban areas, where drainage systems are overwhelmed, submerged hazards can cause serious injuries, from deep cuts to broken bones.

Health Risks and Contaminants

Flood waters are often a toxic brew of pollutants. As the water surges, it can mix with sewage, chemicals, and other hazardous materials, turning it into a hazardous soup. Contact with contaminated water can lead to infections, skin irritations, and gastrointestinal issues. The risk of waterborne diseases, such as leptospirosis, increases significantly after flooding, especially in warm, humid conditions.

Electric Shock

In areas with downed power lines or compromised electrical infrastructure, flood waters can become a conductor of electricity. This presents a significant risk of electrocution, particularly in residential neighborhoods where power lines may not be immediately visible. Even after the storm has passed, standing water can remain electrified, posing a hidden danger.

Swift Currents and Drowning Risk

Many people underestimate the force of moving water. It only takes six inches of fast-moving water to knock over an adult, and just a foot to carry away a small car. During and after a storm, rivers, streams, and drainage channels can swell rapidly, creating powerful currents. Even in seemingly shallow areas, the risk of drowning is real and should not be underestimated.

Structural Instability

Flood waters can compromise the structural integrity of buildings, roads, and bridges. Water can erode foundations, weaken support beams, and cause landslides or sinkholes. Entering or driving on these compromised structures can be extremely dangerous. After the storm, it's crucial to have buildings inspected for damage before reoccupying them.

Wildlife Encounters

Flood waters can displace wildlife, leading to unexpected encounters. Alligators, snakes, and other animals may be forced into populated areas, seeking refuge from rising waters. While these creatures are typically not aggressive, close encounters can still pose a risk, especially in the confusion and stress of a storm.

Safety Precautions and Recommendations

1. Avoid Walking or Driving Through Flood Waters: It’s best to stay on higher ground and avoid any contact with flood waters if possible. Heed road closure signs and do not attempt to cross submerged roads.
2. Turn Off Electricity: If flooding is imminent, shut off the electricity to prevent potential shocks. Avoid using electrical appliances and outlets that may have been exposed to water.
3. Keep Children and Pets Away: Ensure that children and pets are kept indoors and away from flood waters. They are especially vulnerable to the risks of contamination and swift currents.
4. Stay Informed: Monitor local news and weather reports for updates and follow the guidance of local authorities. Evacuate if ordered to do so and know your evacuation routes.
5. Use Proper Protective Gear: If you must enter flood waters, wear protective clothing, including waterproof boots and gloves, to minimize skin contact with contaminated water.
