Also, falling objects can hurt people below scaffolds.

Protect Yourself
Scaffolds are supported (usually by posts/beams and legs) or suspended (by ropes). • OSHA says a scaffold must be designed by a qualified person.* Supported scaffolds must be able to support their own weight and at least 4 times the maximum intended load . • OSHA says a competent person* must inspect a scaffold before each workshift and after anything happens that could affect the structure.

(If you use a screen, the scaffold must be secured against the expected wind force.) OSHA says you must not work on a scaffold that has ice or snow on it — except to get ice or snow off the scaffold. Guidelines for checking a scaffold

• If a scaffold is more than 2 feet above or below a level, there must be a way to get on or off — such as a ladder, ramp, or personnel hoist. The access must not be more than 14" from the scaffold. • Put a standing scaffold on a firm foundation (with base plates attached to feet)— for instance, with one piece of wood under each pair of legs (across the shortest distance), extending at least 1 foot past each leg.
