Using Signs to Protect Employees

Every work environment presents its own unique situations and challenges, so it should be no ‘shock’ to hear that when it comes to electrical safety management, certain things must be done every time. Lets discuss them now.

When a danger signs indicate that there is immediate danger that will result in death if not avoided. The colors associated with a danger sign are red, white or black.


Meanwhile, caution signs indicate potential dangers and often have a yellow background and black letters. These signs indicates a hazard could cause minor injuries. However, the hazard could also cause serious injury or death.

In some cases, the sign even includes the form of a human laying prone to emphasize the danger.


If the voltage of the hazard is consistent, it should be listed on the warning label. Voltage is a measurement of the electrical force passing through the appliance. If the hazard can be potentially lethal or cause serious injury because of the voltage, this should be clearly described on the warning label.

Voltage over 40,000 is almost always fatal. The lower the voltage, the less likely that it will be fatal. However, even voltages as low as 32 have been fatal on rare cases.


The more descriptive the signs, the better. If there are measures that must be taken to avoid electrical shocks, these instructions should be clearly expressed.

If there is enough space, the label should have instructions for what to do if an electrical shock does occur.

Areas with high voltage need to be designated as such so that only qualified individuals can enter the area. When there’s a risk that unqualified employees might come in contact with live parts, visible, high-voltage signs must indicate this.

With the proper labels, employees and contractors can avoid being another shocking tale.
