Unseen Dangers: Safeguarding Your Health During and After a Flood

Floods in Malaysia are one of the natural disasters that frequently hit the country, occurring almost every year, especially during the monsoon season. Today, December 2, 2024, Berita Harian reported that the death toll from floods across the country has risen to six victims, with the latest incident involving two elderly men who drowned while monitoring livestock in Machang, Kelantan, this afternoon. However, the number of flood victims nationwide has decreased to 140,896 people as of 8 PM tonight, compared to 148,024 people at 4 PM earlier.

Floods can be devastating, impacting not just homes and infrastructure, but also our health. As water swells and floods communities, it introduces a multitude of potential health risks that can persist long after the waters recede. In this blog post, we'll explore the health risks associated with floods and provide practical wellness strategies to protect yourself and your loved ones.

Understanding Flood-Related Health Risks

Floods potentially expose individuals to various health hazards, both immediate and long-term.

Immediate threats involve drowning and injuries from debris. In fact, the National Oceanic and Atmospheric Administration (NOAA) reports that flooding is the leading cause of weather-related deaths in the U.S., surpassing hurricanes and tornadoes. Fast-moving water can sweep even strong swimmers away, while debris like broken glass and sharp metal pose serious risks as people navigate through flooded landscapes.

Long-term health risks can be even more alarming. Contaminated floodwater that seeps into homes may harbor bacteria and viruses. According to the Centers for Disease Control and Prevention (CDC), water can be contaminated with sewage, hazardous chemicals, and harmful microorganisms, presenting serious health risks like gastrointestinal illnesses when ingested.

Furthermore, mold can rapidly grow in water-damaged homes, leading to respiratory problems, allergies, and asthma attacks. The World Health Organization (WHO) estimates that up to 30% of buildings in wet, humid climates have dampness and mold problems, increasing the risk of health issues. Effective rehabilitation of homes post-flood is crucial in minimizing these long-term health risks.

Preparing for a Flood

Preparation can significantly enhance safety during a flood.

Start by staying informed about local weather conditions. Obtaining a battery-operated weather radio and subscribing to local alert systems can keep you updated on impending floods and emergencies.

Creating an emergency kit is another vital step. Essential items in your kit should include:

• Non-perishable food for at least three days

• At least one gallon of clean water per person per day

• A comprehensive first-aid kit

• Personal hygiene supplies and medications

  
  

Additionally, ensure all household members know the location of the emergency kit.

Discussing and practicing an emergency plan with your family can greatly reduce anxiety during an actual event. Outline clear evacuation routes and predetermined meeting spots to avoid confusion.

Safety During Floods

If you find yourself in a flooded area, prioritizing safety is crucial.

Avoid walking or driving through floodwaters. Just six inches of fast-moving water can knock an adult off their feet, which can be deceptively dangerous. If you must evacuate, use designated routes and avoid flooded areas altogether.

If you are trapped in your home, move to higher ground if necessary. In a rapidly rising situation, do not hesitate to call for help.

Always listen for emergency broadcasts and follow local authorities' guidance. They are equipped to provide important updates and safety instructions, ensuring your protection.

Post-Flood Health Precautions

Once the floods have receded, focus on your health and well-being.

• Avoid contact with floodwater as much as possible. This water may be contaminated, leading to illnesses. Wear protective gear like boots and gloves when cleaning up.

• Assess damage from a safe distance before returning to affected areas. If you suspect that floodwaters have compromised your home, consult professionals before going back inside.

  
  

During post-flood cleanup, be cautious. Use masks and gloves when handling contaminated materials to protect yourself against harmful inhalation or contact.

Dealing with Mold Growth

Mold represents one of the unseen dangers following a flood that can develop rapidly in dark, damp areas of your home.

After cleanup, drying out your home is essential. Open windows, use fans, and consider deploying dehumidifiers to reduce moisture. If you discover mold, consider hiring professionals specializing in mold remediation for thorough treatment.

For small infestations, a mixture of soapy water may suffice, but if the mold covers an area greater than 10 square feet, professional help is typically required.

Mental Health After a Flood

The aftermath of a flood can significantly impact mental health. Many individuals may experience trauma, anxiety, or depression following such disasters.

Recognizing and addressing these feelings is important. Engaging with community support groups allows survivors to share their experiences and lean on one another for recovery.

Seeking professional help from counselors or therapists can also be beneficial for those who need additional support. Reaching out for help is not just okay; it is a vital step in the healing process.
