In this second edition of Confined Space Entry, an effort began, which was sponsored by the Collection Systems Committee of the Water Environment Federation, to incorporate information regarding confined space entry in collection systems. The purpose of this publication is to assist in the preparation of confined space entry programs for collections systems and wastewater treatment facilities. It is designed to facilitate an understanding of the hazards of working in a confined space as well as the elements of a program that will protect workers required to enter confined spaces.
Considers safety problems posed by wastewater management in confined spaces, spaces large enough to allow employee entry, but which could present the following: limited access or egress; an atmosphere incapable of supporting life or harmful to life; a risk of fire or explosion; or a risk of flooding, mechanical actuation, or engulfment. Approaches the problem through recommendations on policy, training, and safety equipment. Annotation c. by Book News, Inc., Portland, Or.
