Under no circumstances should you leave an electric garland on overnight.
The Ministry of Emergency Situations of Belarus reminded about this.
How to use electric garland correctly
Be sure to turn off the garland at night and when you leave the house.
In case of a sudden voltage drop, a short circuit may occur, followed by a fire.
When choosing a garland, pay attention to the packaging: the box should contain all the basic information about the product in Russian (name, manufacturer, company, purpose, length, permissible voltage and power). There should also be a certificate of conformity.
It is prohibited to use a garland without bulbs or with damaged wires.
The safety of using the garland is also affected by how securely the tree is secured: if it starts to fall and pulls on the wire, a short circuit may occur.
You should not hang several garlands on the tree and plug them into the network at the same time, this can cause an overload of the electrical network and a fire. It is better to buy one powerful garland.
