How to avoid short circuit or electric shock caused by Indoor extension cords in wet environment?

When using indoor extension cords in wet environments, a number of safety precautions must be taken to avoid short circuits or electric shocks. Wet environments increase the risk of electrical equipment malfunctioning because moisture can cause electrical current to flow improperly, which can lead to electrical accidents. Here are some effective preventive measures:

Choose indoor extension cords that are waterproof or moisture-proof, especially those with a high IP rating (Ingress Protection). The higher the waterproof rating, the better the extension cord can resist the intrusion of water vapor or moisture in wet environments, reducing the risk of short circuits.
Although "indoor extension cords" are generally not suitable for wet environments, there are extension cords on the market that are suitable for outdoor use, which are specially designed with waterproof casings and greater moisture resistance. Consider purchasing these outdoor extension cords if you are using them in very wet environments.
Make sure the plug and socket parts of the extension cord are not directly exposed to water or moisture. For example, do not plug the extension cord into a wet wall socket, and do not soak the extension cord in water or place it in a place with severe moisture.
For sockets in wet environments, you can consider using waterproof socket covers, which can effectively isolate the socket from the effects of moisture.
When used in a humid environment, the extension cord should be checked regularly for broken, exposed wires or aging. If the outer sheath of the wire is found to be damaged, replace it with a new extension cord in time to prevent moisture from entering the exposed part and causing a short circuit.
Make sure the insulation layer of the extension cord is not damaged. Especially in a humid environment, the damaged insulation layer will cause the current to come into contact with moisture, greatly increasing the risk of electric shock.

Try to avoid placing the extension cord directly on a wet ground, especially a wet ground or a place with stagnant water. If it needs to be placed on the ground, it can be raised with an extension cord rack or hanging device to avoid contact with water.
In a humid environment, the contact surface of the extension cord should be placed on a waterproof mat or moisture-proof material to reduce the risk of direct contact with moisture.
Choose an extension cord with a switch, which can disconnect the power supply in time during use and reduce the risk of electrical failure in a humid environment. Especially during operation, if the extension cord is found to be wet, the power supply can be quickly cut off to avoid electrical accidents.
Choose an extension cord with an overload protection function, which can automatically cut off the power supply when the current is overloaded or a short circuit occurs, thereby reducing the risk of fire or electric shock caused by a short circuit.
When using extension cords in a humid environment, avoid stretching them too long or bending them excessively, which will damage the wire and insulation layer and increase the chance of moisture penetration.
The connection part of the extension cord is prone to water accumulation or the insulation layer is damaged due to external force, so check the joint part regularly to ensure that there is no damage, leakage or rust.
If the extension cord or appliance is no longer in use, the extension cord plug should be unplugged in time to avoid the risk of short circuit caused by long-term contact with the extension cord due to moisture.
Even if the extension cord is not used temporarily in a humid environment, the extension cord should be put away to avoid long-term exposure to moisture or harsh environments.
Keep the space where the extension cord is used dry and well ventilated. If the environment is humid, consider using a dehumidifier or air circulation device to reduce humidity and thus reduce the impact of moisture on the extension cord.
In a humid environment, it is best to install a residual current device (RCD) on the socket or power line. This device can cut off the power supply in time when the current leaks to avoid the risk of electric shock.
When using an extension cord, avoid the extension cord plug part from contacting wet objects, especially in high humidity environments such as kitchens and bathrooms. Poor plug contact or moisture intrusion into the plug can cause electrical short circuits, burn sockets or cause electric shocks.

When using indoor extension cords in humid environments, the key is to choose suitable waterproof and moisture-proof extension cords, keep the extension cords dry and intact, and take additional safety precautions, such as using overload protectors and leakage protectors. This can greatly reduce the risk of electric shock or short circuits and ensure the safe use of extension cords.
