‘Only half meter of flood water can carry a car away’: NDMA issues crucial guidelines to stay safe during monsoon

During a monsoon flood, safety becomes paramount, and understanding what actions to avoid can make the difference between life and death. The National Disaster Management Authority (NDMA) has issued critical guidelines on what not to do when facing flood conditions due to heavy rains, aiming to protect people from common yet potentially deadly mistakes.

Whether it’s the risks associated with driving through flooded areas, swimming in fast-flowing water, or even using electrical equipment on wet floors, these guidelines are designed to prevent accidents and save lives. We delve into each of these precautions, offering expert insights into why these actions are so dangerous and how to stay safe during a flood.

Avinash Negi, director at Atal Bihari Vajpayee Institute of Mountaineering, and search and rescue expert, Manali, Himachal Pradesh, tells indianexpress.com, “Floods can turn familiar landscapes into treacherous terrains, posing a significant threat to anyone caught in their path.”

Negi says, “Driving through flooded areas, even if the water appears shallow, can be a deadly mistake. Water is much denser than air, creating buoyancy that can lift and destabilise vehicles. Just six inches of fast-moving water can knock a person off their feet, and a mere foot of water can float many cars. As the water rises, it reduces tire traction, making it difficult to steer or brake effectively, potentially leading to loss of control and hydroplaning.”

Floodwaters, he adds, often conceal debris, potholes, open manholes, or downed power lines. Driving through such waters can result in severe damage to your vehicle or even electrocution. Water entering the engine compartment can cause it to stall, leaving you stranded in a dangerous situation.

He says, “The NDMA advises against driving through flooded roads or underpasses, even if they appear navigable. It’s always better to find an alternative route or wait for the water to recede.”

Swimming in fast-flowing flood water

Swimming or wading through fast-flowing floodwaters is an extremely dangerous proposition, says Negi. “Floodwaters can be incredibly powerful, with strong currents and undercurrents that can easily sweep you off your feet. Even experienced swimmers can struggle to navigate these treacherous conditions.”

Floodwaters often conceal debris, submerged objects, or even open manholes. These unseen hazards can cause serious injuries or trap swimmers underwater. They can be contaminated with sewage, chemicals, or other pollutants, increasing the risk of infection and illness.

The NDMA strongly discourages any attempts to swim or wade through floodwaters, he states. “It’s always safer to stay on dry ground and avoid any unnecessary risks.”

Negi stresses that even seemingly shallow water can be deceptively powerful. The force of moving water can easily knock a person off their feet, regardless of their size or strength. The faster the water flows, the greater the risk of being swept away. It’s important to remember that even a few inches of fast-moving water can pose a serious danger.

Avoid electrical hazards

“Using electrical equipment on wet floors, particularly concrete, during a flood can be extremely dangerous,” cautions Negi. “Water is a good conductor of electricity, and any contact between electrical appliances and water can lead to electrocution. This risk is further amplified on concrete floors, which can also conduct electricity.”

He mentions that the NDMA recommends unplugging all electrical appliances and avoiding any contact with electrical outlets or wires in flooded areas, adding that it’s also crucial to “wait for the area to dry completely before restoring power or using any electrical equipment.”

Vacuum cleaners should never be used to remove standing water

Using a vacuum cleaner to remove standing water is a serious safety hazard. Negi informs that the water can damage the motor and electrical components of the vacuum, potentially leading to electrocution or fire.

Safer alternatives for removing standing water include:

*Mops and buckets: A simple mop and bucket can be used to remove water from small areas.

*Wet/Dry Vacuums: These specialised vacuums are designed to handle water and are a safer option for removing larger quantities of water.

*Professional Water Extraction Services: For extensive flooding, it’s best to call in professionals with the right equipment and expertise to safely remove the water.

Negi recommends following the NDMA guidelines to avoid unnecessary risks, and to always err on the side of caution. “If you’re unsure about a situation, it’s best to seek help from professionals or emergency services.”
