When you use underground warning tape, you help keep workers safe. The tape protects important lines and lowers the chance of accidents. Using the tape can save time and money by stopping damage and delays.

Underground Warning Tape Safety

Why Safety Matters

You must always think about safety near buried utilities. Many accidents happen because people do not know where lines are. If you dig without checking, you might hit gas pipes or water lines. You could also hit electrical cables. This can cause fires or floods. It can also make the power go out. Sometimes, workers or people nearby get hurt. You could even get fined or have legal problems if you break the rules.

Before you dig, you have to call 811. This is the law in the United States. When you call, you tell them about your project. You say what work you will do and what tools you will use. You also say how deep you will dig. You give the address and when you want to start. After you call, trained locators come to your site. They mark where the buried utilities are with flags or paint. You must follow these marks while you work.

Note: You need to call 811 two or three business days before digging. This is not just a good idea. It is the law. If you do not call, you could get fined. You might also cause outages or injuries.

Here are the steps you should follow before digging:

StepDescription
1Call 811 two or three business days before you dig.
2Give details about your project, like the type of work, tools, and how deep you will dig.
3Tell them the date and time you will start digging.
4Give the address and any nearby street names.
5Wait for the locators to mark the utilities with flags or paint.
6Follow the marks when you dig.

You keep yourself, your team, and your community safe by doing these steps. Underground warning tape gives extra safety. The tape shows you are close to buried utilities. This helps you avoid making dangerous mistakes.

Preventing Damage and Accidents

You can stop most utility strikes by using the right safety steps. Many accidents happen when people do not call 811 or do not dig safely. Here are some common reasons for utility damage:

  1. Not calling the 811 locator center
  2. Not leaving enough space from marked utilities
  3. Utilities not marked or marked in the wrong spot
  4. Using hand tools or machines carelessly
  5. Mistakes in finding buried utilities
  6. Using old or wrong utility maps
  7. Locator mistakes from people or bad data

You lower these risks by using underground warning tape. The tape is a visual alert. When you see it, you know to stop and check for buried utilities. This easy step can save lives and stop costly repairs.

The table below shows how underground warning tape helps lower accidents and injuries:

EvidenceExplanation
Underground Warning Mesh reduces accidentsWhen you install warning tape the right way, workers can see dangerous areas. This lowers the chance of accidents when digging.

Tip: Always use bright underground warning tape. This makes it easier for everyone to see dangers and stay safe.

You are important for utility safety. By following the right steps and using underground warning tape, you help stop accidents before they happen.

Selecting Warning Tape

Color Codes and Utility Types

You need to choose the right color for your warning tape. The American Public Works Association made a color code system. This system helps you know what utility is underground. Each color means a different kind of line. Look at the table below to match the tape color to the utility:

ColorMeaning
RedElectric power lines, cables, conduit, lighting cables
OrangeTelecommunication, alarm or signal lines, cables, conduit
YellowGas, oil, steam, petroleum, or other gaseous materials
BlueDrinking water lines (potable water)
GreenSewers and drain lines
PurpleReclaimed water, irrigation, and slurry lines
PinkTemporary survey markings
WhiteProposed excavation (planned digging area)

You should always use these color codes. This keeps everyone safe and helps stop mistakes near utilities.

Material and Durability

You want your warning tape to last underground. Pick tape made from strong materials like polyethylene or polypropylene. These materials do not tear easily and can handle soil and water. Some tapes have coatings that resist chemicals. This makes them good for many kinds of soil and weather. Always check if your tape meets industry standards. These standards include D.O.T. Office of Pipeline Safety USAS B31.8 and OSHA 1926-956 (c) (1). If your tape meets these standards, it will work well and keep utilities safe.

Underground Detectable Warning Tape

You must pick between detectable and non-detectable tape. Underground detectable warning tape has a metal layer inside. This layer lets you find the tape with a metal detector. Use underground detectable warning tape when you work with non-metallic pipes. This tape helps you find buried utilities even if you cannot see them. It also meets safety rules for many projects.

Underground detectable warning tape gives extra safety. It works as a visual warning and an electronic marker. You can use it in busy areas or places with lots of buried lines. This tape helps stop damage, service problems, and accidents. Non-detectable tape is best for low-risk places where you do not need to trace the tape later.

Tip: Always check your local rules before you pick your tape. Some places need underground detectable warning tape for certain utilities.

Installing Warning Tape

Placement and Depth

You must put underground warning tape at the right depth. This keeps buried utilities safe. The tape warns anyone who digs in that spot. Always use the tape when building new things or fixing old ones. This step helps stop damage to utility lines. It also keeps people safe.

The best depth depends on the tape’s type and size. The tape should go above the utility line. But it must be deep enough so it does not get moved by work on top. Experts say to put the tape at least 12 inches deep. For most jobs, 24 to 36 inches is even better. This gives a good warning before someone hits the utility.

Here is a table to help you pick the right depth:

Tape SizeRecommended Depth
2" x 1000'10" to 14" deep
3" x 1000'14" to 24" deep
6" x 1000'24" to 36" deep

Match the tape depth to the kind of utility. Water, gas, and electric lines need tape at least 12 inches above them. This way, people see the tape before they reach the line.

Utility LineRecommended Tape Depth
General12 in (30 cm) minimum, 24-36 in (60-90 cm) optimal

Tip: Use high-visibility tape. Bright colors help people see danger and stay safe.

If you use underground detectable warning tape, you get more safety. This tape has a metal strip inside. You can find it with special tools. This helps you find pipes and cables that are not metal.

Marking and Documentation

You need to keep good records when you put in underground warning tape. Mark where you put the tape on your site plans. Write down the depth, color, and type of tape you used. This helps you and others find the utilities later.

Follow these steps for marking and keeping records:

  1. Mark the tape’s spot on your utility maps.
  2. Write down the depth and how far it is from things like buildings or fences.
  3. Note the tape’s color and type, like underground detectable warning tape or non-detectable tape.
  4. Keep all your records safe for the future.

Good records save time and money. They help you avoid mistakes later. They also keep your team and the public safe.

Note: Update your records if you move or change any buried utility lines or warning tape.
