What is the span of lumber?

What is this? Floor joist span is the length of an individual joist, from the foundation walls to an interior beam. The spacing between joists is typically 16”, but can also be 12”, 20”, and 24”. The spacing and ability to span a greater – or smaller – distance is dependent on the size of lumber used for the joists.

### What is the minimum distance required for scaffold planks to extend over the support frame without the use of a cleat?

Each end of a platform, unless cleated or otherwise restrained by hooks or equivalent means, shall extend over the centerline of its support at least 6 inches (15 cm).

### Is it legal to work off a ladder?

Are ladders banned? No, ladders are not banned. They can be used for low-risk, short duration work and where a risk assessment shows that other more suitable work equipment cannot be used due to the layout of the work area.

What is the span of a scaffold plank?

The span of a scaffold plank is the distance it runs between supports. The longer the span, the more deflection (bend) it will have, and therefore, the less its load-bearing capacity will be. For 2 x 10 (nominal) or 2 x 9 (rough) solid sawn wood planks, allowable spans for a given load are shown in the table below:

## Can I use a shorter span for my decking?

Some wood species are stronger than others, so refer to the Decking Span Table below before going to the Deck Joist Span Table. Don’t be afraid to go to use a shorter span if you are unsure. It’s better to build a deck that is strong than bouncy and unstable. Don’t use a board any smaller than what is recommended for that spacing for that species.

## What size wood should I use for a 24 inch planter board?

Don’t use a board any smaller than what is recommended for that spacing for that species. So, for 24 o.c. if you use cedar, it can’t be smaller than a 2×6, Hemlock, can’t be smaller than 5/4×6.
