Preventing Portable Ladder Misuse

Ladder Safety

The Problem

Portable ladders are vital tools on many worksites, but when they’re misused, the consequences can be severe. Improper ladder use can lead to falls, structural failure, and injuries that put you and your teammates at risk. Today, we’ll discuss the most common ladder misuse practices, why they’re dangerous, and how to ensure ladders are used safely and correctly.

Identify the Hazards

  • Falls due to unstable or improperly set-up ladders.
  • Structural failure caused by overloading, modifications, or damaged ladders.
  • Falling tools or equipment obstructing climbing or causing injuries.

Safety Practices and Preventative Measures

Never Use Ladders as Makeshift Scaffolds or Ramps

  • What Not to Do: Don’t set up two ladders with a walkboard across them or lay an extension ladder on saw horses.
  • Why It’s Dangerous: These makeshift setups are unstable and prone to collapse.
  • Safe Practice: Use proper scaffolding systems or elevated work platforms designed for the job.

Do Not Climb the Back Side of a Step Ladder

  • What Not to Do: Never climb the cross-bracing of a step ladder.
  • Why It’s Dangerous: Cross-braces aren’t load-rated and lack slip-resistant features.
  • Safe Practice: Use ladders as designed and only on the climbing side unless labelled otherwise.

Avoid Using Ladders as Tool Racks

  • What Not to Do: Don’t hang tools or materials on ladder rungs or rails.
  • Why It’s Dangerous: Tools may fall or obstruct climbing, increasing the risk of injury.
  • Safe Practice: Use tool belts or designated storage systems.

Do Not Lash Two Ladders Together

  • What Not to Do: Never tie two ladders together to create a longer one.
  • Why It’s Dangerous: It compromises ladder strength and stability.
  • Safe Practice: Use a ladder of the correct height and rating for the job.

Avoid Using Ladders on Unstable Surfaces

  • What Not to Do: Don’t place ladders in truck beds, trailers, or raised platforms.
  • Why It’s Dangerous: Vehicles and uneven surfaces can move, causing ladders to tip.
  • Safe Practice: Set up ladders on stable, level ground.

Do Not Modify or Salvage Damaged Ladders

  • What Not to Do: Don’t attempt to fix a broken ladder with makeshift repairs.
  • Why It’s Dangerous: Modifications reduce structural integrity.
  • Safe Practice: Remove damaged ladders from service and replace them with compliant ones.

One Person at a Time

  • What Not to Do: Don’t allow more than one person on a ladder unless it’s rated for it.
  • Why It’s Dangerous: Exceeds the safe working load and increases the risk of tipping.
  • Safe Practice: Always check load ratings and use ladders as intended.

Real-Life Case or Scenario

Where possible, use an actual incident that you have experienced or been involved in.

Recently, on a local site, a worker used an extension ladder laid across sawhorses as a makeshift scaffold. The ladder slipped, and the worker fell approximately 2.5 metres, fracturing their wrist. This could have been avoided with the use of compliant scaffolding or an elevated work platform (EWP).

Employee Responsibilities

  • Inspect ladders before every use.
  • Use ladders only for their intended purpose.
  • Report damaged or misused ladders.
  • Adhere to weight and safety guidelines.

Employer Responsibilities

  • Provide compliant and suitable ladders.
  • Ensure staff are trained in ladder safety.
  • Remove and replace damaged or non-compliant ladders.

Discussion & Questions

  • Have you ever seen a ladder misused on-site? What happened?
  • What can we do better to ensure safe ladder use across the site?

Encourage everyone to share input and personal experiences.

Commitment/Action Plan

Let’s all commit to using ladders the way they’re meant to be used. If you notice a ladder being misused or in poor condition, stop and report it. A safe setup starts with your decision to do it right.

Wrap-Up

Misusing ladders is entirely preventable. Following these simple guidelines and staying vigilant ensures we avoid injuries and stay safe on the job. Thanks for your time, and let’s keep safety front of mind every day.

Standards Overview

Canadian workplace health and safety regulations require that ladders be suitable for the task, maintained in safe working condition, and used in accordance with manufacturer instructions. Unsafe modifications and unstable setups are prohibited. Refer to the Canadian Centre for Occupational Health and Safety (CCOHS) Good Practice Guidelines for safe ladder use.
