Recently, some netizens said that they can buy a living blue ring octopus with “one of the world’s most toxic marine organisms†in the online shopping mall. According to store owners, people buy this octopus mainly for pets. Experts reminded that blue ring octopus belongs to highly toxic organisms. Once it is paralysed, there is no anti-virus serum treatment and it is not suitable for pets. In the same way, if you do not pay attention to some safety hazards during the renovation, it is also very dangerous. Let us talk about the hidden dangers in the decoration today.
First, mixed cold and hot water pipes
White is a cold water pipe, red is a hot water pipe, and a cold water pipe and a hot water pipe are mixed together.
There are hidden dangers: the expansion and contraction rate of hot and cold water pipes is different. Due to thermal expansion and contraction, the cold water pipes burst and leak.
Standard operation: distinguish hot and cold water pipes according to color and operate strictly.
Second, use glue
There are many types of glue used for decoration on the market. It is difficult for consumers to distinguish whether glue is environmentally friendly.
There are hidden dangers: release a lot of harmful substances, harming human health.
Normative operation: At present, there is no natural and pollution-free glue on the market. The substitute is 108 glue. However, we must look for better brands and look for products with test reports.
Third, there is no set of insulation pipe
During the construction, the wires are directly buried in the wall. The wires are not covered with insulating tubes, and the wire connectors are directly exposed.
There is a hidden danger: this is very unsafe, and after the arrival, the wire may be short-circuited due to the aging of the wire and the wire may be short-circuited. At the same time, if the wire breaks, the wire cannot be changed at all, only the wall knocks on the ground.
Standard operation: The wires must be laid with insulation sleeves on the outside, and the circuit joints should not be exposed on the outside. They should be installed in the line box. No joints are allowed between the distribution boxes.
Fourth, free to change the waterway
In the case that the owner did not understand the decoration, he misled the owner to dismantle the waterway at random and wasted money.
There are hidden dangers: waste of money is only one aspect. Once it is not sealed or lacks pressure during the demolition of the waterway, it will lead to burst of water pipes.
Normative operation: When the pipeline is changed, it will move and it must not be moved when it is not.
Fifth, place strong and weak electricity together
Typical jerry cuts. Put strong electricity such as lighting wires and weak electricity such as telephone lines and network cables in a pipe or box, and lay less pipes, saving time and effort.
There are hidden dangers: There will be interference when making a call or surfing the Internet. At the same time, too much threading in a pipe also creates a risk of fire.
Normative operation: Strong and weak electricity should be routed separately. It is forbidden to share one pipe and one bottom box for strong and weak electricity.
Sixth, the length is not enough without connection accessories
Because the length of the insulating tube is not enough, there is exactly a turn here, no connection fitting is placed, and a section is exposed at the intersection with the junction box.
There are hidden dangers: If you stay for a long time, it may cause leakage due to the aging of the line.
Normal operation: There should be something connected between the nozzle and the junction box.
Seventh, repeated wiring
A large number of repeated wiring, multi-use materials, waste the owner's financial and material resources.
There are hidden dangers: Once a problem arises in the line, it is difficult to detect it in a layout like "Tian Luo Di Network."
Normative operations: Arranged closely, in the case of no more than 40% of the capacity of the pipe, the same trending line can be worn in a pipe. However, it is necessary to separate strong and weak electricity.
Eighth, the line pipe was damaged by the follow-up project
Typical barbaric construction. After the pipeline was laid, it was slotted on the ground again and the pipeline was laid through.
There are hidden dangers: After you check in, you may find that there is no electricity in a room in your home. You can only detect and re-thread all the wires in your home.
Normative operation: The construction cannot be performed again in the place where the pipeline is laid. If it is damaged, it is forbidden to wire in the middle when changing lines.
Ninth, putty when cement
Typical shoddy. Not to mention the horizontal slot, after the completion of the line pipe wiring, actually putty powder as cement.
There are hidden dangers: The horizontal slotting during the decoration has destroyed the bearing weight of the entire building, and the original design's ability to resist earthquakes has decreased.
Normative operation: The cement used to plug the trunk must be consistent with the cement of the original structure to ensure its strength.
Tenth, wire separation
All lines use a single color, for the sake of labor.
There are hidden dangers: once the line is in trouble, the line of discordance is detected again.
Standard operation: FireWire uses red wire and red cloth, neutral wire is blue, green and black, and it is coated with the same kind of color wire cloth, and the ground wire applies yellow, green and blue wires.
