A tube and coupler scaffold has a platform supported by tubing, and is erected
with coupling devices connecting uprights, braces, bearers, and runners. Due to
their strength, these scaffolds are frequently used where heavy loads need to
be carried, or where multiple platforms must reach several stories high. These
scaffolds can be assembled in multiple directions, making them the preferred
option for work surfaces with irregular dimensions and/or contours.

Two new OSHA fact sheets - "Tube and Coupler Scaffold Planning and Design" and
"Tube and Coupler Scaffold Erection and Use" - were recently published by the
U.S. Department of Labor.

They help employers to protect construction workers using this type of scaffold
on the job. Workers building scaffolds are at risk for serious injury from
falls and tip-overs, being struck by falling tools and other hazards, and
electrocution from energized power lines. Before starting any scaffold project,
employers should conduct a hazard assessment to ensure the safety of workers.
