INTRODUCTION
You should know how to select and erect ladders and scaffolds to reach an area that cannot be reached
from the ground. Safety is of prime importance in the erection and use of ladders and scaffolds. The
number of serious accidents caused by scaffolds and ladders that are not erected or used properly far
exceeds those from other sources. Improper use or assemblage of scaffolds or ladders not only
endangers you, but it is also a potential death trap for anyone under the items.
PART A: LADDERS
4-1. Ladders. Ladders are devices that are used to gain access to work that is performed at higher
levels. It is possible to paint the entire exterior surface of a one- or two-story building from a ladder;
however, it is often more comfortable and timesaving If a scaffold is erected. Ladders are of several
types: single rung, extension, step, and trestle. Each ladder is designed for a specific use and should not
be used for any other purpose. Ladders are made of magnesium, aluminum, steel, or well-seasoned
wood which is free of knots or other defects.
