OSHA-Compliant Ship Ladders – Alaco Ladder Company

OSHA-Compliant Ship Ladders

OSHA Compliant Ship Ladder SpecsWhen shopping for aluminum ship ladders, the Occupational Safety and Health Administration (OSHA) imposes several safety and structural guidelines. Overlooking them could get you in trouble with health and safety inspectors. Contrary to popular belief, you cannot just install cheap, random ladders on business premises, especially if you manage several workers regularly. You need OSHA-compliant ship ladders.

OSHA generally defines ship ladders by their measurements. Under standard number 1910.21(b), ship stairs or ladders have open risers, rails, and treads that horizontally slope between 50° to 70°. Note that they don’t fall under standard stairs.

Alaco Aluminum Ships Ladders have a reputation of being among the sturdiest in the industry. Using only high-quality, high-strength 6061-T6 aircraft grade aluminum alloy, our OSHA-compliant exterior ladders and OSHA-compliant roof access ladders are manufactured for extra safety and longer life, while meeting strict industry standards.

Virtually maintenance-free, our aluminum OSHA-compliant ship ladders never need painting and offer superior scratch resistance to ladders constructed of lower-grade alloy or steel. Additionally, every ladder is designed to fit specific conditions, (using standardized components) for flexibility and efficiency. Our OSHA-compliant exterior ladders and OSHA-compliant roof access ladders are designed for a fixed, permanent installation utilizing Alaco heavy-duty aluminum brackets.


Standard 1910.25(b)(1) requires OSHA-compliant ship ladders to have railings on each side. Handrails and guardrails will make climbing steep treads much easier, especially for your less mobile, flexible workers. OSHA rarely allows the lack of rails. If you demonstrate that attaching handrails only compromises your workspace further, you must propose an alternative fall protection system.

1910.25(b)(3) and (4)

We ensure that our OSHA-compliant exterior ladders and OSHA-compliant roof access ladders have uniform tread depths and riser heights. Unusually shaped or placed steps can cause accidents, especially in hectic spaces where workers move quickly.

Also, all platforms and landings equal the width of the stair. If you need to place them beside an entryway, we can adjust the platform so that an open door compromises less than 20″.


Aluminum ship ladder models have varying load limits. However, OSHA requires that each step should have the capacity to support at least a concentrated load of 1,000 lbs. or five times its intended load, whichever is smaller. For instance, let’s say your aluminum ship ladder has a manufacturer-rated capacity of 500 lbs. It should withstand loads lighter than 1,500 lbs.

Fortunately, our OSHA-compliant exterior ladders and OSHA-compliant roof access ladders consist of heavy-duty, aircraft-grade alloy capable of withstanding more than the minimum weight limit. They won’t buckle even if a hefty adult male carrying several tools climbs them.

1910.25(c)(2), (3), and (4)

Our OSHA-compliant ship ladders meet all the minimum height and width requirements and then some. They have a minimum tread depth and width of 9.5″ and 22″, respectively, while the riser height also caps at 9.5″.

1910.25(d)(1), (2), (3), and (4)

As for spiral stairs, the maximum riser height stops at 9.5″ as well. However, the minimum clear width, headroom clearance, and tread depth measurements are 26″, 6’ 6″, and 7.5″, accordingly.

Using Aluminum Ship Ladders and Stairs

You can’t use aluminum ship ladder models in a typical office setting, but they’re a popular choice in industrial work environments. Our units consume less space, accommodate 1,000+ pounds, and require minimal maintenance. You can use our OSHA-compliant exterior ladders and OSHA-compliant roof access ladders for roof hatch and mezzanine access.

However, OSHA advises employers to use ship stairs sparingly. Although they’re efficient and convenient, their steeper treads make them slightly more dangerous to use. Mobility-impaired users can’t maneuver these steps. Standard number 1910.25(b)(8) even dictates that employers must first prove the impracticality of standard stairs before installing ship ladders.

Get Quality, Top-Grade OSHA-Compliant Ship Ladders

Invest in top-grade aluminum ship ladders. Your workers will regularly use them while carrying heavy items, so it’s imperative to have a heavy-duty unit. If you continue using a non-compliant unit, not only will you end up wasting money, but you’ll also endanger your staff.

Contact us at Alaco Ladder Company for more information on our available OSHA-compliant ship ladders. We have dozens of roof hatch and mezzanine access stairs. Just call (888) 310-7040, and our personable sales team will explain your options.

OSHA-rated Aluminum Ladder | Alaco Ladder

For Contractors, OSHA-rated Heavy-duty Aluminum Ladder Products Are A Must

Aluminum ladders come in all shapes and sizes, from standard units used around the house to professional-grade, heavy-duty aluminum ladder units. But no matter the size and form they take, it’s a good idea for contractors to choose OSHA-rated aluminum ladders and check the product’s duty rating before purchasing one.

The duty rating specifies the maximum amount of weight that a ladder can safely carry. The American National Standards Institute (ANSI) lists these five categories:

  • Type III – These are ladders with a maximum weight capacity of 200 lbs. Type III ladders are typically the basic units used around the house. They are best for jobs that do not require the user to carry anything up and down the ladder.
  • Type II – Also known as medium-duty ladders, these are also appropriate for home use such as when hanging Christmas lights. Tradesmen and farmers can also use these ladders for basic jobs. Medium-duty ladders can carry up to 225 lbs.
  • Type I – These ladders can carry up to 250 lbs. Also called heavy-duty ladders, these are often used in commercial applications or for any user looking to carry lightweight items up and down the ladder. These ladders come in multiple forms, including multi-purpose ladders, stepladders, and some attic ladders.
  • Type IA – These ladders have a maximum capacity of 300 lbs. These are usually meant for industrial use. Ladders with this type of rating allow the user to carry heavy items up and down the ladder. If you are an architect, contractor, or working in construction, a heavy-duty aluminum ladder with this ANSI rating is the one you’ll likely choose.
  • Type IAA – These are ladders for special duty or high-impact industrial or professional use wherein the user is looking to carry extremely heavy items up and down the ladder. These can accommodate up to 375 lbs.

According to the Occupational Safety and Health Administration (OSHA), falls from portable ladders such as straight, combination, and extension ladders are one of the leading causes of workplace-related injuries and fatalities. As such, architects and contractors who want to ensure the utmost safety when designing and building commercial buildings should always choose OSHA-approved heavy-duty aluminum ladder products with the appropriate duty rating.

Ladder-related accidents usually end in falls and painful injuries. Never assume that the length of the ladder or some other characteristic corresponds with the ladder’s duty rating. Also, don’t take a ladder’s recommended use at face value. While a Type I ladder is good for basic use, if the weight it regularly carries is beyond 250 lbs. the ladder could eventually break.

If you’re an architect or contractor, be sure to carefully consider the type of heavy-duty aluminum ladder you need, with safety and efficiency in mind. Remember, the more the ladder will support, the more expensive it will be, but it will also be safer. Also, take advantage of training courses that our aluminum ladder company provides.

Here at Alaco Ladder Company, we have the course Reaching the Roof: Specifying Fixed Access Aluminum Ladders for Safety and Efficiency. In this course, we discuss the different types of fixed access ladders, safety codes and standards, and the importance of having OSHA-certified heavy-duty, professionally-built aluminum ladders in commercial buildings.
