Matching the Ladder to the Task

Choosing the right ladder isn’t just about convenience but also about safety, efficiency, and compliance. Using the wrong type can increase the risk of falls, damage property, and even breach workplace safety obligations.

Step and extension ladders are the most common types on Australian worksites and in homes. Both have their strengths, but they’re designed for different situations. Knowing when to use each can help you work faster, safer, and with fewer headaches.

Step Ladder: Pros and Cons

Pros

• Limited reach compared to extension ladders

• Bulkier to transport than a single-section ladder

• Not suitable for roof access or very high work

Extension Ladder: Pros and Cons

Pros

• Greater reach is ideal for roof access, gutters, and second-storey work

• Adjustable height for different tasks

Side-by-Side Comparison

Safety Tips and the 4:1 Rule

• 4:1 Rule: For every 4 metres of ladder height, place the base 1 metre away from the wall.

• Maintain three points of contact at all times.

• Inspect ladders before use for cracks, loose rungs, or bent rails.

• Use accessories like ladder stabilisers or levellers when conditions demand extra security.

• Never overreach, climb down, and reposition instead.

Making the Right Choice

A step ladder is often the safest and most efficient option if you work indoors or on a quick, low-height task. An extension ladder is essential for outdoor, high-reach work, especially for roof access.

Pair your ladder with the right accessories to prevent slips and movement for maximum safety. For example, a stabiliser for an extension ladder can make a big difference in safety and compliance.
