Rental Customer Questions About Digging Safety
- Do I need to call 811 before renting and using a mini excavator for a backyard project?
- Yes, absolutely. The 811 call requirement applies to any excavation, regardless of depth or project size. This includes homeowners digging fence post holes, installing irrigation systems, or planting trees. When you rent a mini excavator or trencher through Rntr, you are responsible for contacting 811 before the equipment arrives on site. Most rental providers will ask whether you have completed a locate request before the rental begins.
- How far in advance do I need to call 811 before my rental dig date?
- The standard notice period in most U.S. states is two to three full business days before you plan to dig. Some states require more. In Florida, for example, the law requires a minimum of two full business days notice. In Texas, it is also two business days. Always check your state's specific 811 digging laws, since requirements vary. Submit your locate request as soon as you know your dig date so markings are complete before your rental equipment is delivered or picked up.
- Is the 811 service free to use?
- Yes. Calling 811 or submitting a request through the call-before-you-dig online portal at 811.com is completely free. Utility companies are required by law to send locators to mark their underground lines at no charge to you. There is no reason to skip this step. The cost of repairing a severed gas line, fiber optic cable, or water main far exceeds any minor inconvenience.
- How deep can I dig before calling 811?
- There is no minimum depth that exempts you from the call-before-you-dig requirement. Even shallow digging of just a few inches can strike a utility line, since burial depths vary significantly based on soil conditions, past excavation, erosion, and when lines were originally installed. Some fiber optic cables are buried as shallow as six inches. The safest and legally compliant answer is: call 811 before any digging, at any depth.
- What equipment rentals on Rntr require me to complete a utility locate first?
- Any equipment that penetrates or disturbs the ground requires a utility locate before use. This includes mini excavators, full-size excavators, trenchers, augers, skid steers with attachments, tillers, and even some fence post drivers. If you are unsure whether your planned rental requires a locate, contact your local Rntr rental provider before your dig date. They can help you determine what steps to take before the equipment arrives on site.
- What happens if I hit a utility line while using rented excavation equipment?
- Stop work immediately and do not attempt to move the equipment or repair the line yourself. If you suspect a gas line has been struck, evacuate the area and call 911. For other utilities, call the utility company directly and notify your rental provider. Liability for utility line damage caused by failure to follow proper locate procedures typically falls on the excavator, which could include you as the renter. This is another critical reason to complete the 811 process before your rental dig date.
- Can I do an online call-before-you-dig request instead of calling 811 by phone?
- Yes. Most states now accept online locate requests through 811.com, which walks you through the process and routes your request to the appropriate utility companies in your area. Some states have their own dedicated portals as well. Online requests carry the same legal standing as a phone call, and many experienced contractors prefer the online option because it provides a confirmation record. Submit your request with accurate location details and a description of your planned dig area.
Understanding 811 and Call Before You Dig Laws
The specific requirements vary by state:
- Texas: Texas law (Texas Utilities Code Chapter 251) requires a minimum two-business-day advance notice. Penalties for violations can reach $10,000 per incident.
- California: The DigAlert system covers California, with a two-business-day notice requirement.
- Most other states: Two to three business days is the standard, but always verify your specific state's requirements.
The APWA Color Code: Reading Utility Markings on Your Job Site
- Red: Electric power lines, cables, and conduit
- Yellow: Gas, oil, steam, petroleum, or other gaseous or flammable materials
- Orange: Communication lines, cable TV, telephone, and fiber optic
- Blue: Potable water
- Green: Sewers and drain lines
- Purple: Reclaimed water, irrigation, and slurry lines
- Pink: Temporary survey markings
- White: Proposed excavation area
Gas line digging safety deserves special attention. A ruptured gas line can cause fires, explosions, and asphyxiation. If you see yellow markings anywhere near your planned dig zone, reduce your excavation area, use hand tools to expose the line, and maintain extra clearance before bringing any powered equipment near those markings.
Markings are typically valid for a set number of days (often 28 days in most states) before a new locate request is required. If your project extends beyond that window, you must re-notify before continuing to dig.
Excavation Site Preparation: Steps to Take Before Breaking Ground
1. Submit your 811 locate request. Do this at least two to three business days before your scheduled rental pickup or delivery. Use the online portal or call 811 directly. Keep your confirmation number.
2. Wait for all utility operators to respond. Just because some markings appear does not mean all utilities have responded. Confirm with your One Call center that all operators in your area have cleared or marked before you begin. Some areas have multiple operators for the same utility type.
3. Survey the marked area. Walk the job site after markings are placed. Note the location of all colored flags and paint lines relative to your planned dig area. Take photos for your records.
4. Establish hand-dig zones. Most states and OSHA guidelines require hand digging within a tolerance zone of 18 to 24 inches on either side of any marked utility line. Use shovels, hand trowels, or vacuum excavation equipment in these zones rather than powered digging equipment.
5. Brief everyone on the site. If you have helpers or a crew, walk them through the utility markings before work begins. Excavation safety tips are only effective when the entire team understands the hazards.
6. Inspect your rental equipment. Before operating a mini excavator or trencher, confirm the attachment being used is appropriate for the soil conditions and that the operator understands the depth constraints near utility lines.
7. Dig cautiously and progressively. Work in layers, especially in zones near marked utilities. Stop and reassess any time you encounter unexpected resistance, discolored soil, an unusual smell, or any sign of buried infrastructure.
Hand Digging Around Utilities: When and How to Do It Right
- Dig parallel to the utility line first to establish its depth, then work carefully around it.
- Vacuum excavation (also called hydrovac or soft digging) is an increasingly popular option for safely exposing utilities in tight areas. Some Rntr rental providers carry vacuum excavation equipment.
- If you uncover a line, do not move it, pry against it, or attempt to lift equipment over it without professional guidance.
- Mark exposed utilities clearly with additional flags or caution tape so crew members and equipment operators know exactly where the hazard is.
Trenching Safety and Excavation Safety Tips for Deeper Digs
- Excavated soil and spoil piles must be placed at least two feet from the edge of the trench to prevent collapse.
- Access and egress must be provided every 25 feet in trenches four feet or deeper.
- Trenches near roadways, heavy equipment, or in unstable soils require additional precautions.
- Water accumulation in a trench signals immediate danger. Do not enter until water is removed and stability is confirmed.

How to Avoid Hitting Utility Lines: Common Mistakes and How to Prevent Them
Assuming a previous locate is still valid. Utility markings expire. If your project runs longer than the validity period (typically 28 days), you must submit a new locate request. Digging on expired markings is treated the same as digging without any markings under most state laws.
Not accounting for unmarked private utilities. The 811 system covers public utility operators, but private lines on your property are not always included. Irrigation systems, landscape lighting, propane lines, and utility connections between buildings on the same property may not appear in any locate database. You are responsible for knowing the location of private utilities on your property.
Treating the marked line as the exact utility location. Locators mark approximate centerlines. The actual utility may be several inches off due to locating equipment tolerances and soil conditions. The tolerance zone exists precisely because markings are not guaranteed to be exact. This is why hand digging in that zone is required.
Skipping the locate because the project seems small. Many utility strikes happen on minor projects, fence post installations, tree planting, and mailbox posts. The depth of the hole does not determine whether a locate is required. The act of digging requires a locate, full stop.
Not maintaining visual contact with markings during excavation. Rain, foot traffic, and equipment movement can obscure surface markings. Check that flags and painted lines are still visible throughout the project. Refresh or replace markers that have been buried or displaced before continuing work.
Utility line damage prevention is ultimately a discipline built from consistent habits. Renting excavation equipment through Rntr is straightforward, but the responsibility for following safe excavation practices always rests with the operator. Make the 811 call your first step every time, without exception.
