Annex A Accessibility - Typical distances required for
          tools in corrosion protection work
Annex B Recommended minimum dimensions of openings for
          access to confined areas
Annex C Minimum dimensions for narrow spaces between
          surfaces
Annex D Design features which may be used to avoid
          deposits accumulating or water being trapped

Covers the basic criteria for the design of steel structures to be coated by protective paint systems so as to avoid premature corrosion and degradation of the coating or structure. Provides examples of appropriate and inappropriate design, showing how problems of application, inspection and maintenance of paint systems can be avoided. Also deals with measures for facilitating handling and transporting of the steel structures.
