Types of Ladders
Ladders are not one-size-fits-all tools. Each design serves a specific job. So, using the wrong type puts both the worker and bystanders at risk. Below, find a full breakdown of the most common types of ladders, and what each one does.
Stepladders
The stepladder ranks as the most familiar ladder, in both homes and workplaces. It is a self-supporting, A-frame structure. So, it doesn't need a wall for support. You can set it up in the middle of a room, in a kitchen, or in an open space.
Stepladders work great for painting interior walls, or replacing light fixtures. They also suit shelf work and light repairs. Typically, they range from 4 to 12 feet tall. One key rule: never stand on the top two rungs. This hurts stability. In fact, it ranks among the leading causes of falls.
Extension Ladders
Extension ladders are non-self-supporting. So, they lean against a wall or structure. They have two or more sections that extend to reach great heights. Commonly, this means 16 to 60 feet. In Canada, Ontario's rule O. Reg. 213/91 sets a cap. Two-section extension ladders must not exceed 18 metres (60 feet), for Grade 1 and 1A ladders.
These ladders work as the top choice for roofing, exterior painting, and gutter cleaning. They also suit large construction jobs. Because they need a solid surface, proper angle placement matters a lot. So, follow the 4-to-1 rule. Move the base one foot out, for every four feet of height.
Platform Ladders
Platform ladders look similar to stepladders. But, they add a broad, flat platform at the top. Often, a safety rail wraps three sides. This design lets workers stand for long periods, without gripping rungs. So, it suits tasks that need two free hands, like drywall work or electrical wiring.
You commonly find them in retail stores and warehouses. Also, they show up on commercial construction sites. Platform ladders are self-supporting too. And, they offer far more stability than a standard stepladder, for long overhead work.
Straight (Single) Ladders
A straight ladder has one section. It is non-self-supporting, so it must lean against a wall or solid surface. Unlike extension ladders, you cannot adjust the length. Straight ladders work well when you need access close to a wall. Think exterior maintenance, roofing access, or specific construction tasks.
Canadian rules under O. Reg. 213/91 set a cap too. Single ladders must not exceed 9 metres (30 feet) in length, for Grade 1 or 1A ratings.
Multi-Purpose (Articulating) Ladders
Multi-purpose ladders rank as the most versatile type of all. With simple hinge adjustments, you can set them up as a stepladder. Or, as an extension ladder, scaffolding base, trestle ladder, or staircase ladder. For tradespeople who need one ladder for many jobs, these prove highly practical and cost-effective.
Their flexibility makes them popular in renovation work, general contracting, and electrical work. In these fields, job needs can shift throughout the day.
Telescoping Ladders
Telescoping ladders collapse into a compact form. So, they're easy to transport and store. Yet, they still extend to real heights when needed. They work much like an extension ladder, but retract section by section. So, they suit workers who move often between job sites. They also work well when vehicle storage runs tight.
Trestle Ladders
A trestle ladder is a self-supporting, double-sided ladder. Think of it as a heavier-duty stepladder, built to support two workers at once. Crews commonly use them in large painting jobs, or warehouse work. They also help when two people need to work on the same area, at the same time.
Fixed Ladders
Fixed ladders are permanent structures. You'll find them on buildings, communication towers, industrial gear, and confined spaces. Under OSHA's rule 29 CFR 1910.28, fixed ladders over 24 feet need a certified fall protection system. This means either a Personal Fall Arrest System (PFAS) or a Ladder Safety System. Meanwhile, Canadian rules under SOR/86-304 require fixed ladders to meet ANSI Standard A14.3 design rules.
Types of Ladders in Construction
Construction sites demand the most from ladders. Workers face uneven ground, shifting heights, rough weather, and hard physical tasks, all at once. So, choosing the right type of ladder affects both output and safety.
Extension ladders work as the workhorse of the construction site. Crews use them for roofing access, exterior framing, window work, and fascia jobs. However, workers must always secure the top first. They must also set the angle correctly, before anyone climbs. Notably, a ladder that slips at the base ranks among the top causes of fatal falls in construction.
Stepladders serve a key role indoors too. Think drywalling, ceiling work, electrical rough-ins, and plumbing. Their self-supporting design suits rooms where walls sit unfinished or hard to access.
Multi-purpose ladders keep growing in popularity on Canadian sites. This happens because they cut the number of ladders a crew must carry. In fact, one well-set articulating ladder can replace three separate units. This saves both equipment costs and setup time.
Platform ladders have found a strong role in commercial interior work too. When a worker needs both hands free, a platform ladder helps a lot. Think conduit work, ductwork, or ceiling jobs. Its wide platform and safety rail give stability that a standard stepladder cannot match.
The Infrastructure Health & Safety Association (IHSA) in Ontario has a clear rule. All portable ladders on a project must meet design, performance, and marking rules. These cover Grade 1, Grade 1A, or Grade 1AA, under CSA standards. Notably, these grades set the load capacity of the ladder. This matters a lot when workers carry tools while climbing.
Types of Ladders OSHA Safety Guidelines
OSHA's ladder standard sits under 29 CFR 1926.1053. It applies to construction settings. In fact, it ranked fourth on OSHA's most cited violations list, for fiscal year 2024. Canadian workplaces follow provincial rules instead, not OSHA directly. Still, many Canadian standards line up closely with OSHA's core ideas.
For Canadian workers, each province has its own law. For example, in Ontario, the Occupational Health and Safety Act (OHSA) and O. Reg. 213/91 govern site safety. In British Columbia, WorkSafeBC sets the rules. Meanwhile, Alberta follows the OHS Act. Notably, in 2024 alone, WorkSafeBC issued 152 penalties for weak fall protection.
- Key guidelines that apply across all types of ladders include:
- Ladders must support their maximum intended load at all times.
- Place all ladders on stable, level surfaces, and secure them where they could shift.
- Extension ladders must extend at least 3 feet (0.9 m) above the landing point when used for roof access.
- Workers must maintain three points of contact while climbing - two hands and one foot, or two feet and one hand.
- Keep ladders free from oil, grease, or wet surfaces.
- Employers must maintain records of ladder inspections, training, and any incidents.
Note: Requirements may vary depending on your workplace, province, or specific industry. Always consult your provincial OHS authority for the regulations that apply to your situation.
Different Types of Ladders Explained
Knowing the different types of ladders goes beyond just knowing their names. Load capacity, material, and duty rating all shape which ladder fits a given task.
Ladder Duty Types: Every ladder sold in North America carries a duty rating. This rating shows the max load it can hold. That includes the worker, plus their tools:
- Type IAA (Extra Heavy Duty) - supports up to 375 lbs; for industrial and construction use
- Type IA (Extra Heavy Duty) - supports up to 300 lbs; industrial use
- Type I (Heavy Duty) - supports up to 250 lbs; construction and industrial environments
- Type II (Medium Duty) - supports up to 225 lbs; commercial use
- Type III (Light Duty) - supports up to 200 lbs; household use only
Never use a Type III household ladder on a construction job site. Going over the load rating risks sudden structural failure.
Ladder materials matter a lot too. Aluminum ladders are light, tough, and resist rust. But, they conduct electricity. So, never use them near electrical panels or power lines. Fiberglass ladders, on the other hand, don't conduct electricity. This makes them the go-to choice for electricians, and anyone working near live power. Wooden ladders are the old-school choice. They carry electricity less than aluminum does. But, they can warp and wear down over time. So, they need regular checks.
Ladder Safety Tips for Workers and Home Use
Knowing the types of ladders is only half the job. How you use them decides whether you go home safe, at the end of the day.
Before You Climb: Always inspect your ladder before use. Look for cracked rails, damaged rungs, missing feet, loose bolts, and signs of rust. A ladder that looks fine from far away can still hide hairline cracks. These cracks can weaken the whole structure.
Setting Up Correctly: Proper setup ranks among the most skipped parts of ladder safety. For extension ladders, apply the 4-to-1 angle rule. Secure the top with rope ties, ladder hooks, or a standoff stabilizer. And, never place a ladder on boxes, pallets, or any shaky surface.
While Climbing: Keep three points of contact at all times. Always face the ladder, both going up and coming down. Also, keep your body centered between the rails. Never overreach to either side. If you can't reach something with ease, climb down and move the ladder instead.
Weight and Load Limits: Always know the duty rating of your ladder. Then, factor in your body weight, plus any tools you carry. Notably, overloading brings a real risk, with no visible warning signs.
Common Mistakes That Cause Falls: Overreaching stands as the top cause of ladder falls. Standing on the top rung of a stepladder comes second. And, using a damaged ladder, just because it "seems fine," comes third. For a closer look at these errors, and how to stop them, read Common Ladder Accidents and How to Avoid Them.
Choosing the Right Ladder for Safe Use
Choosing the right ladder comes down to four key factors. These are the task height, the setting (indoor or outdoor, near power or not), the load you'll carry, and how long you'll stand there.
Indoor tasks at medium heights include painting, fixture work, and ceiling repairs. For these, a stepladder or platform ladder in the 6-to-10-foot range meets most needs. For outdoor work above one storey, an extension ladder works as the standard choice. Meanwhile, electricians and utility workers must use fiberglass ladders.
A simple decision guide:
- Is there a stable surface to lean against? → Extension or straight ladder
- Do you need to work without wall support? → Stepladder or platform ladder
- Will you be near electricity? → Fiberglass only
- Do you need both hands free for extended periods? → Platform ladder with safety rail
- Are you working at multiple heights on the same site? → Multi-purpose articulating ladder
The right choice saves time, cuts risk, and keeps your crew within provincial OHS rules. Always check with your provincial authority, before starting any elevated work.
Stay Safe - Follow Proper Ladder Safety Practices
Ladder safety does not happen on its own. It takes real knowledge, steady habits, and a clear grasp of both the gear and the setting. So, every time you skip an inspection, or use the wrong ladder, you make a choice with real risk.
Fall accidents injure more than 40,000 workers in Canada every year, per OHS Canada. Falls from height remain a top cause of deadly workplace accidents in the country. These numbers stand for real people. And, almost every one of these events was avoidable.
