OSHA Standards for Ladders by Alaco Ladder
Alaco Ladder builds every ladder system to meet or exceed OSHA and ANSI safety standards. Our exterior roof access ladders comply with OSHA 1926.1053, and our ship ladders and access stairs follow OSHA 1910.25.
Ladder safety is not optional. According to the CDC, around 500,000 people in the U.S. are treated for ladder-related injuries each year, and more than 300 of those injuries are fatal.
As a ladder manufacturer with over 100 years of experience, Alaco helps reduce that risk by building compliance into every product we make.
What Are the OSHA Standards for Exterior Ladders?
OSHA regulates exterior and fixed ladders under standard 1926.1053, covering load capacity, safe use, and ladder condition. All Alaco exterior roof access ladders meet these requirements for chimneys, towers, refineries, and other industrial applications.
OSHA 1926.1053(a): Load Capacity
OSHA requires ladders to support 3.3 to 4 times their maximum intended load. Alaco exterior ladders, built from aircraft-grade aluminum alloy, carry three to four times their rated limits — with room for workers, tools, and equipment.
OSHA 1926.1053(b): Safe Use and Rail Extension
This section requires stable placement and side rails extending 3 feet above the landing surface. When full rail extension isn’t possible, Alaco adds sturdy grab attachments to help users stay compliant on site.
OSHA 1926.1053(b)(17): Damaged Ladders
Fixed ladders with corroded parts, split rails, or missing steps must be taken out of service. Alaco backs every product with a 5-year warranty plus repair and maintenance services to keep your ladders compliant.
What Are the OSHA Standards for Ship Ladders?
OSHA regulates ship ladders under standard 1910.25, covering fixed stairways in general industry.
OSHA 1910.25(b): Fixed Stair Requirements
Fixed stairways must have handrails, 6′ 8″ of vertical clearance, uniform treads and risers, 30″ landings, and support 5 times the anticipated live load (minimum 1,000 lbs). Alaco’s high-strength aluminum alloy stair systems comfortably meet all load and clearance requirements.
OSHA 1910.25(d): Spiral Stairs
Spiral stairs require 6′ 6″ headroom, 7.5″ tread depth, 26″ clear width, and a maximum 9.5″ riser height. All Alaco spiral stair products are built to these measurements — ideal for space-limited facilities.
OSHA 1910.25(e): Ship Ladders
Ship ladders must be installed at 50 to 70 degrees with open risers between 6.5 and 12 inches. Alaco aluminum ship ladders meet these angle and riser requirements, giving your facility safe, steep-access climbing in tight areas.

What angle does OSHA require for ship ladders?
Under OSHA 1910.25(e), ship ladders must be installed at 50 to 70 degrees from horizontal, with open risers providing a vertical rise of 6.5 to 12 inches between treads. All Alaco ship ladders are manufactured to meet these requirements.
Does OSHA require handrails on ship ladders?
Yes. OSHA 1910.25(b) requires handrails and stair rails on all fixed stairways, including ship ladders. Where rails are not feasible, employers must provide an approved alternative fall protection system.
What happens if I use a damaged fixed ladder?
OSHA 1926.1053(b)(17) prohibits using fixed ladders with corroded parts, split rails, or missing steps. Doing so is considered negligence and can affect liability and insurance claims. Alaco offers repairs, maintenance, and a 5-year warranty to help keep your ladders compliant.

Alaco ladders are built from aircraft-grade aluminum alloy that is as strong as structural steel but lighter, with superior scratch resistance. This gives them the strength to exceed OSHA load requirements while remaining durable and low-maintenance.
