Solution Summary: Portable Mini Scaffold
A portable mini scaffold is an engineering control that provides painters with a larger elevated base to work from than a conventional stepladder. The mini scaffold has four manually locking wheels and four levels to adjust plank height.
The portable mini scaffold is a collapsible scaffold system that is 46-1/8 in. wide, 50-1/8 in. high and a depth of 25-1/2 in. The frame and planks are made out of steel and are powder coated. The two scaffold planks are rated to hold 500 lb of combined material and worker weight. The portable mini scaffold is ideal for elevated work on level hard surfaces found inside residential homes and commercial buildings. Falcon Ladders and Mfg. offer extension outriggers that increase the base width to 58 in, depth to 26-3/4 in, and height to 6 ft, increasing working height and stability.

Heavy lifting and carrying can cause low back disorders, such as muscle strain or a disc herniation (“slipped disc”), which is bulging of disc material possibly pressing on the spinal cord or nerves that go into the leg. The portable mini scaffold can reduce heavy lifting and carrying by providing workers with a device which they can load and use to transport material around the job site.
Overhead work can cause shoulder muscle strains; tendonitis, which is inflammation of the tendons; or rotator cuff tears, which is a rupture of a shoulder tendon. The portable mini scaffold can reduce overhead work by providing a platform for painters to stand upright at the level of the working surface.
How Risks are Reduced:
The portable mini scaffold can be loaded with materials and transported around the jobsite reducing the amount of heavy lifting and carrying performed by workers. The portable mini scaffold also provides a platform for painters to stand upright at the level of the working surface, reducing the amount of time workers spend doing overhead work.
Manufacturers state, “This sturdy unit is made of powder coated steel that hauls up to 500 lb but is lightweight for transporting. High grade wheels provide smooth gliding.” The manufacturer also states, “multiple working levels allow you to get close to your project.”
The National Institute for Occupational Safety and Health (NIOSH) has concluded that there is strong evidence that low back disorders are associated with work-related lifting and forceful movements (Bernard et al. 1997). Using the portable mini scaffold to transport materials at the job site reduces work related lifting. A reduction in the amount of time a worker spends manually handling materials reduces the risk of low back injury. Additionally, there is strong evidence that sustained shoulder elevation is associated with shoulder tendonitis (Bernard et al. 1997). The portable mini scaffold provides workers with an elevated platform to paint and prep walls. The scaffold elevates workers to the height of the painting surface reducing the amount of overhead work and time spent elevating the arm.
Effects on Productivity:
Productivity will increase because the portable mini-scaffold provides a platform for workers to move with ease when painting or prepping elevated surfaces.
Care should be taken when working from the top two rungs to avoid tipping the scaffold. Workers should ensure that the wheels are locked. Falcon Ladders and Mfg. have an outrigger system available for purchase that increases stability, increases available working height, and comes with an additional platform.
The manufacturer states “outriggers give the traditional fold-up scaffold an untraditionally stable, solid foundation.”
