Place the ladder so no one walks more than 25 feet (7.62 m) to reach it, according to Legal Information Institute. This limit applies to trench excavations 4 feet (1.22 m) or deeper.
Key takeaways for place the trench ladder within the travel limit before anyone enters
- Travel distance: A stairway, ladder, ramp, or other safe means of egress must be located so that employees require no more than 25 feet (7.62 m) of lateral travel, according to Legal Information Institute.
- Depth trigger: This lateral travel requirement applies to trench excavations that are 4 feet (1.22 m) or more in depth, according to Legal Information Institute.
- State variation: California Code of Regulations, Title 8, Section 1541. General Requirements. states that a stairway, ladder, ramp, or other safe means of egress shall be located in trench excavations that are 4 feet or more in depth so as to require no more than 25 feet of lateral travel for employees, according to California Department of Industrial Relations.
- Spoil setback: Keep materials or equipment at least 2 feet (.61 m) from the edge, or use retaining devices that stop them falling or rolling in, or use both, according to Legal Information Institute.
- Action step: Pace the walk to the ladder before entry and record the distance against the 25-foot limit to verify compliance on site.
Where the ladder goes and how far a person may walk
The rule requires a stairway, ladder, ramp, or other safe means of egress in trench excavations that are 4 feet (1.22 m) or more in depth, according to Legal Information Institute. This placement must ensure that employees require no more than 25 feet (7.62 m) of lateral travel to reach the egress point. The source specifies that this requirement applies to the lateral distance an employee must walk within the trench to access the ladder or ramp. It does not specify the vertical distance or the type of ladder, only the lateral travel limit. See portable ladder checks before climbing.
When positioning the ladder, measure the horizontal distance from the furthest working point in the trench to the base of the ladder. If this distance exceeds 25 feet (7.62 m), the ladder is not placed correctly for that work area. You may need to move the ladder closer to the work zone or add additional ladders if the trench is long. The 4 feet (1.22 m) depth threshold is the trigger for this specific lateral travel requirement. If the trench is shallower than 4 feet (1.22 m), this particular rule regarding the 25-foot lateral travel limit does not apply, according to Legal Information Institute.
Illustrative example of a trench walk
A trench is 4 feet deep, so the lateral travel rule is on. One ladder is at the work area. The furthest walk along the trench floor is 25 feet, which meets the limit. Spoil sits 2 feet back from the edge. If the crew will work past that point, add another ladder so each walk stays within 25 feet. Write that paced distance next to the trench spot before anyone enters.
The travel distance each page prints for a trench ladder or ramp
The specific lateral travel limit printed on these pages is 25 feet, which equals 7.62 meters. This figure appears in the text of the federal regulation maintained by the Legal Information Institute. Washington State Legislature’s WAC 296-155-655 also specifies that a stairway, ladder, ramp or other safe means of egress must be located in trench excavations that are four feet (1.22 m) or more in depth so as to require no more than 25 feet (7.62 m) of lateral travel for employees, according to Washington State Legislature.
Ohio Administrative Code Rule 4123:1-3-13 presents the distance in a split line format. The text reads "to require no more than twenty-five feet (7.6 meters) of lateral," according to Ohio Administrative Code. When you pace the distance on your job site, you are checking against the 25-foot figure. The rule requires that the egress point be located so that the lateral travel for employees does not exceed this printed limit. Once the trench is 4 feet deep, the 25-foot lateral travel limit applies.

The trench depth that turns the ladder rule on
The ladder requirement activates at a specific trench depth, distinct from the depth that triggers shoring. According to the Ohio Administrative Code, an adequate means of egress is required in trenches four feet (1.2 meters) deep or more. This four-foot mark is the threshold where the ladder rule turns on for that specific jurisdiction's text. You must place the ladder, ramp, or stairs so that workers can reach it without exceeding the travel distance limit once the trench reaches this depth.
It is critical to distinguish this ladder trigger from the shoring trigger on the same page. Do not assume that because you are shoring a trench, the ladder rule is automatically satisfied or that the depths are identical.
When you are on a job site in Ohio, check the depth of your trench against these two specific figures. If your trench is four feet deep, you need the ladder in place and accessible. The Ohio Administrative Code does not present these as a single combined threshold; they are separate lines of text with separate depth numbers.
Other jurisdictions may print different depth numbers for these same requirements. The four-foot and five-foot figures cited here come specifically from the Ohio Administrative Code page. If you are working in a different state, you must check that state's specific administrative code for its own depth triggers. Do not apply Ohio's four-foot ladder trigger to a job site in another state without verifying the local rule. The depth that turns the ladder rule on is a jurisdiction-specific number, and the Ohio Administrative Code provides the figures for Ohio work.
A filled reference table of the ladder and spoil distances
The table below lists the specific figures printed on the pages for the Legal Information Institute and the California Department of Industrial Relations. Each row keeps the travel distance, depth trigger, and spoil or air numbers tied strictly to that publisher's text. You can use this to verify your site plan against the exact source you are following.
| publisher | travel distance it prints | depth that turns the rule on | any spoil or air number it prints |
|---|---|---|---|
| Legal Information Institute | 25 feet (7.62 m) | 4 feet (1.22 m) | 2 feet (.61 m) spoil; 19.5 percent oxygen |
| California Department of Industrial Relations | 25 feet | 4 feet | 2 feet spoil; 19.5 percent oxygen |
The Legal Information Institute page notes that atmospheres shall be tested before employees enter excavations greater than 4 feet (1.22 m) in depth where oxygen deficiency exists, defined as less than 19.5 percent oxygen, according to Legal Information Institute.
The California Department of Industrial Relations page states that atmospheres shall be tested before employees enter excavations greater than 4 feet in depth where oxygen deficiency exists, defined as less than 19.5 percent oxygen, according to California Department of Industrial Relations.
Use the row for the specific source you are citing in your daily log. Keep the metric figures attached to the Legal Information Institute row and the imperial-only figures attached to the California Department of Industrial Relations row. Do not mix the two sets of units in a single entry.
Spoil setback beside the ladder rule
Spoil setback appears on the same regulatory text as the ladder rule, so you can check it in one pass.
Spoil setback. Materials and equipment must be placed and kept at least 2 feet (.61 m) from the edge of excavations, or protected by retaining devices sufficient to prevent them from falling or rolling in, or by a combination of both if necessary, according to Legal Information Institute. The California Department of Industrial Relations prints the same 2-foot requirement without the metric figure, stating protection shall be provided by placing and keeping such materials or equipment at least 2 feet from the edge of excavations, or by the use of retaining devices, or a combination of both, according to California Department of Industrial Relations. Washington State Legislature uses the phrasing "must be provided" and includes the metric equivalent, stating protection must be provided by placing and keeping such materials or equipment at least two feet (.61 m) from the edge of excavations, or by the use of retaining devices, or a combination of both, according to Washington State Legislature.
A blank line for today's trench ladder check
Before anyone climbs into the excavation, you must pace the walk to the ladder and write down the trench location, the distance, and which page you used. Use the Construction Daily Log Checklist for Supervisors. This single line keeps the record tied to the specific spot where the crew is working. Do not assume the distance is the same on every page or for every site condition.
| line | trench spot | paced walk | page used |
|---|---|---|---|
| Example | far end of the trench | a short walk along the floor | the page for that job |
Today, pace the furthest walk and fill the blank rows before anyone climbs in.
FAQ about the trench ladder
How far may the walk to the ladder be?
The rule limits lateral travel to no more than 25 feet (7.62 m) for employees to reach a stairway, ladder, ramp, or other safe means of egress, according to Legal Information Institute. The California Department of Industrial Relations also states that the lateral travel requirement is no more than 25 feet, according to California Department of Industrial Relations. Pace the actual walk from the work area to the ladder entry point to verify it stays within this limit before anyone enters the trench.
Which depth turns that rule on?
The ladder requirement applies to trench excavations that are 4 feet (1.22 m) or more in depth, according to Legal Information Institute. Measure the vertical depth of the excavation to determine if this specific egress rule is triggered for your site.
What to do with the spoil pile?
Materials and equipment must be placed and kept at least 2 feet (.61 m) from the edge of excavations, according to Legal Information Institute. This setback can be achieved by keeping the spoil pile at that distance or by using retaining devices that prevent materials from falling or rolling into the excavation, according to Legal Information Institute.
What to write down today?
Record the trench location, the paced distance to the ladder, and the specific page used for the rule in your daily log. This documentation confirms that the travel distance was measured and verified against the source text before entry.
