Choosing the Right Ladder: A Matter of Load and Logic
The Problem
Many workers assume all ladders are the same, but this is a dangerous misconception. Choosing the wrong ladder is like driving a vehicle on a bridge that can’t hold the weight—it’s a recipe for failure and serious injuries. Ladders are manufactured with specific categories and load ratings designed for different tasks, tools, and weights. Today, we’ll cover how to select the correct ladder to prevent accidents and keep everyone safe on site.
Identify the Hazards
- Using the Wrong Ladder: Domestic ladders (e.g., household-use types) used in a commercial setting can fail under heavier loads.
- Exceeding Load Ratings: Overloading ladders can lead to structural failure and serious falls.
- Ignoring Combined Weight: Workers often forget to account for tools, materials, PPE, and body weight when selecting a ladder.
- Lack of Inspection: Labels stating the ladder’s load rating may be missing, faded, or ignored.
Safety Practices and Preventative Measures
1. Understand Ladder Types
- Self-Supporting Ladders: Step ladders, platform ladders, articulated ladders, and dual-access ladders.
- Non-Self-Supporting Ladders: Extension ladders and single ladders, which require a stable supporting structure.
2. Know the Load Ratings (based on CSA standards):
- Light Duty: Up to 100 kg — for light home use only.
- Medium Duty: Up to 125 kg — suitable for light trade work.
- Heavy Duty: Up to 150 kg — for heavy-duty use on job sites and construction work.
- Always select ladders rated for heavy-duty industrial use when working on commercial or construction sites.
3. Critical Safety Calculation
- Add up:
- Your body weight
- PPE and work clothing
- Tools and materials carried up the ladder
- Ensure the total weight is within the ladder’s load rating.
4. Inspect Ladders Before Use
- Ensure the load rating label is present and legible.
- Look for cracks, missing rungs, bent rails, or worn labelling.
5. Avoid Common Misuse
- Never exceed the rated capacity.
- Do not use ladders marked as light-duty or residential for professional work.
- Always double-check ratings before use.
Real-Life Case or Scenario
A worker grabbed a domestic ladder (rated 100 kg) for a job involving frequent lifting of materials. The combined weight of the worker, PPE, and gear exceeded the limit. Mid-task, the ladder failed, causing a fall and a broken arm. This incident could have been prevented by selecting an industrial-rated ladder appropriate for the task.
Employee Responsibilities
- Use only ladders rated for the specific task.
- Calculate total load (body + gear + tools) before use.
- Inspect ladders before use and check that the load rating is visible and appropriate.
- Report any missing labels or visible damage immediately.
Employer Responsibilities
- Provide ladders that meet CSA safety standards and are fit for purpose.
- Ensure all load rating labels are legible.
- Train workers on how to properly select ladders and calculate safe loads.
Discussion & Questions
Commitment/Action Plan
Starting today, commit to inspecting your ladder before each use and ensuring the load rating is suitable for your task. Don’t guess—when in doubt, ask your supervisor.
Wrap-Up
Selecting the right ladder isn’t about convenience—it’s about safety. Using the correct type and rating reduces the risk of collapse and injury. Thank you for making ladder safety a priority on this site.
Standards Overview
CCOHS refers to CSA standards for ladder safety.
- Ladders must display visible load ratings.
- Only ladders suited to the task and environment may be used.
- Regular inspections must be carried out to ensure ladders remain safe to use.
