Object and Fundamental Principles

The Regulations in this chapter lay out the broad scope of the standard, as already explained above. Regulation 110-04-01 advises that adherence to the standard is also intended to ensure compliance with statutory requirements. There is a list of the relevant statutory Regulations in Appendix 2 of the standard. 

This chapter now simply states that the standard aims to provide systems that are safe and which function properly. Regulation 120-02-01 states that invention, and new materials which may infringe the standard, are not prohibited provided they attain a comparable degree of safety and their use is noted on the completion certificate. 

Section 130-01-01 clarifies that the purpose of the standard is to protect persons, property and livestock against the injurious effects of electric shock, burns, mechanical movement of electrically actuated equipment, and explosion. So only trained, competent and conscientious operatives should be employed and the materials should be suitable and of good quality to the appropriate British or other standard. 

Section 133 addresses, among other things, the need for installations to be verified by using inspection and testing to ensure that the provisions of BS 7671 have been met. 

Part 2 provides an extensive list of definitions of terms used throughout the standard. One definition that needs to be clarified is that of the earthing arrangements. There are four descriptors in general use which are used both in BS 7671 and in this book. They are TN-S, TN-C-S, TT and IT systems. In these abbreviations, the letters have the following meanings

RADWASS has been organized in a hierarchical structure of four levels of safety documents. The top-level publication is a document of safety fundamentals which provides the basic safety objectives and fundamental principles to be followed in national waste management programmes. The lower levels include safety standards, safety guides, and safety practice documents. The series has been structured in a logical and clear manner to reflect the systems approach to waste management.
