What is the maximum allowed height between ladder rest platforms?

Asked by: Amy Daniels

These are meant to protect climbers as they ascend. Previously, a fixed ladder with a cage required a landing platform at a maximum interval of 30′ feet. The new regulations change this requirement dramatically. Fixed ladders without cages must now have a landing platform at maximum intervals of 150′ feet.

At what height does OSHA require a ladder rest deck?

As you can see from §1926.451(e)(2)(iii), when attachable ladders are used on supported scaffolds more than 35 feet high, they must have rest platforms at no more than 35-foot intervals. There is no requirement in the standard that workers use fall protection while climbing up or down these ladders.

How far above a platform should a ladder extend?

The side rails of through or side-step fixed ladders shall extend 42 inches (1.1 m) above the top of the access level or landing platform served by the ladder.

How tall can a ladder be without a rest platform?

The current OSHA standard at §1910.27(d)(2) establishes a maximum limit of 30 feet between platforms; therefore, ladder distances in excess of 30 feet without an intermittent platform would not be in compliance with the standard.

What are the maximum intervals for rest platforms for a fixed ladder?

Response: 29 CFR 1910.28(b)(9)(ii)(B) requires that ladders equipped with a personal fall protection or a ladder safety system shall have rest platforms provided at maximum intervals of 150 feet (45.7 m).

What are OSHA regulations for ladders?

The minimum clear distance between side rails for all portable ladders must be 11.5 inches (29 cm). edge of a landing area must be no less than 7 inches (18 cm) and no more than 12 inches (30 cm). A landing platform must be provided if the step-across distance exceeds 12 inches (30 cm).

How high can a platform be without a step OSHA?

Vertical clearance above any stair tread to any overhead obstruction is at least 6 feet, 8 inches (203 cm), as measured from the leading edge of the tread.

What is the minimum overlap required for extension ladders taller than 48 feet?

Each section of an extension ladder should overlap the adjacent section by a minimum num- ber of feet, depending on overall length. For ex- tension ladders up to 36 feet long, overlap should be at least 3 feet; for ladder lengths between 36 and 48 feet, overlap should be at least 4 feet.

What is the minimum distance an extension ladder must extend beyond the surface to be accessed?

Summary Statement. Describes the OSHA rules for use of a portable ladder to access an upper landing surface – the side rails must extend at least 3 feet above the landing surface.

What are support requirements for fixed ladders?

Fixed ladders must be able to support at least two loads of 250 lbs. each. Rungs must be shaped to minimize slipping. For more information on the requirements for fixed ladders, see the OSHA Standard, 29 CFR 1910.27 Fixed Ladders.

What is the minimum amount of force guard rails must be able to support?

Guardrail systems shall be capable of withstanding, without failure, a force of at least 200 pounds (890 N) applied within 2 inches (5.1 cm) of the top edge, in any outward or downward direction, at any point along the top edge.

How long must extension ladder sections overlap?

3 feet

Each section of a multi-section ladder must overlap the adjacent section by at least 3 feet for ladders up to 36 feet and 4 feet for 40 feet or longer extension ladders.

What height is fall protection?

OSHA requires that fall protection be provided at elevations of four feet in general industry workplaces, five feet in shipyards, six feet in the construction industry and eight feet in longshoring operations.

Are ladder cages still required?

OSHA ladder cage requirements 2021

Fall protection is now required on all fixed ladders that extend higher than 24 feet. (Previously, OSHA required cages for fixed ladders taller than 20 feet.)

What is the correct rule for safe ladder placement?

4 to 1 rule

The base of the ladder should be placed so that it is one foot away from the building for every four feet of hight to where the ladder rests against the building. This is known as the 4 to 1 rule.

At what depth of a trench does OSHA require fall protection?

5 feet

Trenches 5 feet (1.5 meters) deep or greater require a protective system unless the excavation is made entirely in stable rock. If less than 5 feet deep, a competent person may determine that a protective system is not required.

What is OSHA height work?

‘Work at height’ means work in any place where, if there were no precautions in place, a person could fall a distance liable to cause personal injury (for example a fall through a fragile roof down an unprotected lift shaft, stairwells).

At what height and above is fall protection required on a scaffold?

10 feet

The standard requires employers to protect each employee on a scaffold more than 10 feet (3.1 m) above a lower level from falling to that lower level.

How deep can an excavation be without shoring?

5 feet

How Deep Can a Trench Be Without Shoring? Trenches with a depth of 5 feet (1.5 meters) or greater need a protective system unless the entire excavation is in stable rock. If there is anything less than 5 feet, it is up to a competent person’s discretion to determine if there is a need for a protective system.

What type of soil Cannot be benched?

Type C soil cannot be benched.

What is the difference between a trench and an excavation?

What is the difference between an excavation and a trench? OSHA defines an excavation as any man-made cut, cavity, trench, or depression in the Earth’s surface formed by earth removal. A trench is defined as a narrow excavation (in relation to its length) made below the surface of the ground.

What are the OSHA requirements for trenches?

A stairway, ladder, ramp or other safe means of egress shall be located in trench excavations that are 4 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. Exposure to vehicular traffic.

When a trench is 4 feet or more in depth a means of egress from the trench must be within of employees in the trench?

25 feet

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.

What is the OSHA construction standard?

The construction standard (29 CFR 1926.501(b)(1)) states that fall protection is required when an employee is working on a walking/working surface (horizontal and vertical surface) with an unprotected side or edge which is six feet or more above a lower level.

What depth do you need a trench box?

5 feet

When trenches reach a depth of 5 feet or more, OSHA requires contractors to use a protective system. Protective systems are also required for trenches less than 5 feet deep if the soil might have the propensity to cave in when the trench is dug (such as with sand or mud).

When a trench is 4 feet or more in depth?

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. Type C soil is more stable than Type A soil.

When using a ladder in a trench What must it be?

The ladder must extend at least 3′ above the top of the trench and be placed on firm ground within the trench. A ladder must be provided every 25 feet of lateral travel.

How high should a trench box be above ground?

Trench boxes are generally used in open areas, but they also may be used in combination with sloping and benching. The box should extend at least 18 in (0.45 m) above the surrounding area if there is sloping toward excavation.

Do trench boxes prevent cave ins?

Shield or sometimes referred to as “trench box” or “trench shield” prevents workers from being trapped inside a trench or excavation in event of cave-ins. They also protect workers from any material falling apart from excavation faces and from possible collapse of adjacent structures.

What two requirements must be met so that a trench does not need to have a protective system installed?

The standard does not require the installation and use of a protective system when an excavation (1) is made entirely in stable rock, or (2) is less than 5 feet deep and a competent person has examined the ground and found no indication of a potential cave-in.
