Safety Message on Electrical Safety During Floods

Water and electricity do not mix. To ensure your safety and the safety of your family during the current wet season, Sarawak Energy wishes to share these important safety measures in case of floods.

If heavy rain is anticipated in your area, you should be prepared as electrical hazards are major safety risks during and after floods. Preparing for flood conditions and responding to them effectively can reduce the danger.

Electrical appliances exposed to flood water can be extremely dangerous if re-energized without proper reconditioning or replacement. Flood damage to electrical equipment can sometimes be hidden.

Moisture can get into electrical insulation or debris may be lodged inside the equipment. Floodwaters can also be polluted with chemicals, sewage, oil or other contaminants.

These and other factors can affect the ability of electrical equipment to perform properly making the equipment destructive and dangerous.

However, there are steps you can take to ensure your safety. The following are some electrical safety tips to help you in mitigating the risk of electrocution or fire.

Flood Precaution (Before)

  • If you are not sure whether your home is in an area of potential flood risk, check with the District Office or Drainage and Irrigation Department or local authorities.
  • In an area where immediate flooding is anticipated, switch off all electrical power by turning off the main switchboard.
  • If you have time before you evacuate your home or business, move as much electrical equipment as possible to floors or areas above the anticipated flood level.
  • For removal of fixed electrical appliances such as electric motor, fan and other heavy machineries (if and when necessary), engage a licensed contractor for safety reasons.  

 

It is important not only to be well prepared to face pre and post flood situations. Always have flashlights and batteries ready as flood may occur at night.


During a Flood

  • If flooding occurs or upon the advice from the authorities to immediately leave the building, please do so as water and live electrical wires can be a lethal combination.
  • If you have not turned off your main power switch, do not attempt to turn it off once water has entered the building.
  • Do not enter flooded basements or buildings that may contain energized electrical wiring or appliances, and do not touch damp walls.
  • Do not go near or interfere with SESCO electrical installations which are submerged or affected by flood water.  
  • If you are boating in a flooded area, avoid power lines, as the water level may cause the boat to be too close to the wires for safety. It is not advisable to travel by boat at night or when you do not have good vision on the location of power lines. Avoid getting too close to SESCO power lines or any electrical installations.
  • Do not return to your home until you know it is safe or have been advised by the authorities that it is safe to do so.


After the Flood Recedes

  • If your home or business has been flooded, electrical hazards may exist long after the water recedes. Even if water is not visible in a building, the interior structure may be soaked and still prone to electrical hazard.
  • Do not enter flooded basements or buildings that may contain energized electrical wiring or electrical appliances.
  • Stay clear of anything that could conduct an electric current such as metal pipes, metal ladders, and even damp wood.
  • Exercise extreme caution when returning to your home or business after a flood. Do not assume that any part of a flooded electrical installation/ appliance is safe.

 

Warning! When an electrical appliance or installation has been in water, it cannot be turned on again without risk of electrocution or fire.

  • If your electrical main switch was not turned off prior to evacuation, do not enter the building until a qualified electrician has determined it is safe to do so.
  • If the main electrical switchboard / internal wiring is affected by the flood, customers may seek the service of a SESCO registered electrical contractor. The list may be obtained from any SESCO Office.
  • Do not attempt to connect any electrical appliances, which have been affected (totally or partly submerged) unless you are advised it is safe to do so by a competent technician or electrical repair shop.
  • Before switching ON the main supply, have a qualified electrician inspect all wiring. Even if your building is not flooded, the interior structure may be soaked and still be a conductor of electricity.
  • If you plan to use a generator for backup power, make sure that the generator and all connected equipments are in a dry and well-ventilated location.
  • If in doubt or if there is any query, customers may seek help by calling Sarawak Energy’s Customer Care Centre which operates 24 hours a day, 7 days a week.offices as follows:
