Inspecting Float (Ship) Scaffolds
A float (ship) scaffold is a suspension scaffold consisting of a braced platform resting upon two parallel bearers and hung from overhead supports by ropes of fixed length.
- Make sure platforms are supported by, and securely fastened to, a minimum of two bearers extending at least 6 inches beyond the platform on both sides.
- Ensure rope connections do not allow the platform to shift or slip.
- Check to make sure only two ropes are used with each float.
- Make sure ropes are arranged to provide four ends that are securely fastened to overhead supports, and that each rope:
- is hitched to one end of the bearer
- passes under the platform and is hitched again at the other end
- leaves enough rope for supporting ties
- Ensure each employee on a float (ship) scaffold is protected by a personal fall-arrest system.
- Check for the following for maximum intended loads of 750 pounds:
- Platforms are made of ¾-inch plywood.
- Bearers are made from 2 x 4-inch or 1 x 10-inch rough lumber, and free of knot and flaws.
- Ropes have a strength equivalent to at least 1 inch-diameter, first-grade manila rope.
