If you are planning to dig or excavate in an area where there are buried electrical cables, you need to take precautions to avoid damaging them and causing power outages, injuries, or even fatalities. One of the best ways to do this is to use underground electrical warning tape, which is a colored, non-adhesive film that is laid over the cables to alert anyone who digs in the area of their presence.
Underground electrical warning tape is made of low-density polyethylene (LDPE), which is a durable and flexible material that can withstand harsh environmental conditions. The tape is printed with a caution message and the name of the service, such as “Caution: Electric Cable Below” or “Warning: High Voltage Cable”. The tape is also color-coded according to the American Public Works Association (APWA) standards, which specify different colors for different types of utilities.
For example, red is used for electric power lines, orange for communication lines, yellow for gas pipelines, and so on.
The benefits of using underground electrical warning tape are:
It helps to prevent accidental damage to underground cables, which can result in costly repairs, service interruptions, legal liabilities, and safety hazards.
It helps to protect workers and equipment from electric shocks, burns, or explosions that can occur when digging near live wires.
It helps to comply with the Occupational Safety and Health Administration (OSHA) regulations, which require covering the location of underground utility lines with a suitable material1.
It helps to identify the type and location of underground cables, which can facilitate maintenance, inspection, or emergency response.
How to Use Underground Electrical Warning Tape
To use underground electrical warning tape effectively, you need to follow these steps:
Before you start digging, you need to locate and mark the underground cables using a cable locator device or by contacting the utility company or the local authorities.
You need to choose the right type of underground electrical warning tape for your project. There are two main types: detectable and non-detectable. Detectable warning tape has a metallic core or wire that can be detected by a metal detector or a cable locator device. Non-detectable warning tape does not have a metallic core and can only be seen visually2.
You need to lay the underground electrical warning tape over the cables at a depth of 12 inches (30 cm) below the surface or as specified by the local codes3. You need to ensure that the tape covers the entire length and width of the cable and that it is visible from all directions.
You need to secure the underground electrical warning tape with soil or sand and avoid using sharp objects or tools that can damage it.
You need to inform anyone who works in the area about the presence and location of the underground electrical warning tape and instruct them not to dig or disturb it.
