Cautions about overall electrical items
Once rats enter indoors or buildings, they easily get into machines. They may tear wirings and leave
excrement that can cause serious damage to machines.
If rats tear wirings, it may cause short circuits. And it could cause a serious problem to machines.
If rats leave excrement over printed circuits boards or bared cables, it will be carbonized and may cause
fire.
REFERENCE:
Below is an example we had fire from a board. (See the pictures below.)
You can see blue-green attached material on the burnt location.
When copper burns, Cuo (copper oxide II) is black and Cu2O (copper oxide I) is red. According to the
blue-green color, the attached material can be considered Copper hydroxide. By this fact, we suppose water
existed on the burnt location.
COUNTERMEASURE:
1．Keep the room clean, neat and organized.
2．Lock up the room with no openings.
If once rats came in;
3．Sprinkle rat repellent.
4．Catch rats with adhesive sheets. (Emergency countermeasure)
5．Hire an rat exterminator.
To prevent damage caused by rats, it is important to keep rats-free environment.
If already rats are in your space, exterminate them by using rat repellent or other ways as mentioned above.
