All manner of signs are used to warn people of danger. Metal signs, cardboard signs, digital signs, and even stickers or labels are used. In the case of electrical components, such as transformers and cables, you will want the sticker or label type of sign. They are easy to manufacture, and easy to use. Additionally, they will not cause you additional harm because electricity will not disburse through a plastic label like it can through a metal sign. Here is how you can use these stickers and labels for electrical purposes.
Pre-printed Warnings on Transformer Labels
Transformers control thousands of volts of electricity every minute. They are lethal to anyone that does not see or heed the warning on the transformer itself. Avoiding death and injury is as simple as ordering some pre-printed warning labels and placing these labels on parts of transformers where the labels are easily seen before anyone attempts to touch these devices. The use of bright orange with CAUTION is common, as is the sign of a stick figure getting shocked to the ground by a voltage star. If you need something that is more customized, talk to the sign manufacturer to see what can be added to these labels.
Color-Coded Cable Markers
Color-coded cable markers are another excellent product to remind others not to touch these cables without proper safety gear and safety protocols. You can use individual colors for different cables, or utilize the safety regulations with regards to color-coding. If you want to print cable wire numbers on these labels, then you can also purchase a blank sheet of colored labels that are printer-friendly and printer-ready. Just type what you need to type into the boxes that represent your sheet of cable markers and print.
Lightning Bolts and Voltage "Stars"
These pictorial representations of high voltage and electrical energy may also be purchased from sign manufacturers as labels. The reason why transformer labels work so well is that they are weatherproof, they last a long time, and you cannot get electrocuted from a plastic or paper sticker. You can request the voltage "stars" or lightning bolts at any size, and you can use whatever colors to show how dangerous a particular electrical area really is. Red, orange, and yellow are the most common.
The label signs only stick to hard surfaces. You can put them in or on anything you do not want other people to touch. Since these symbols are universal with electrical dangers, those that cannot read or cannot read English will still understand what these signs mean.
