Title Discussion paper on the standardisation of manholes and inspection openings
Original title Ein Diskussionsbeitrag zur Normung von Befahr- und Besichtigungs÷ffnungen [in German]
Bibliographic information July-Aug. 1978, Vol.19, No.7-8, p.241-246. Illus. 17 ref.
Abstract As inspection openings and manholes are not indispensable and in fact are often considered to be undesirable from the engineer's point of view, this aspect of maintenance and safety is often neglected. This paper gives the historical background and current trends in the pertinent West German regulations, and reviews, with tables and diagrams, the dimensions and number of openings required for various types of equipment (boilers, pressure vessels, storage tanks, etc.) by the regulations of the Federal Republic of Germany and other European countries. The problem of accessibility to the openings is more difficult than that of their dimensions and number, but it is very important, having regard to safety and rescue of workers trapped inside. Using anthropometric measurements and data on visual capacity and the possibilities of movement of the human body it should be possible to standardise inspection openings, irrespective of the type of recipient concerned and its use.
