Green Guide - Paragraph 11.8

Crush barriers – continuous crush barrier configuration

The configuration of crush barriers – that is, their layout in relation to each other and to the gangways – has a crucial influence on the safe management of spectators in standing areas.

Experience at sports grounds indicates that the safest configuration is to provide crush barriers along the full width of a terrace or viewing slope, with gaps only at the radial gangways. Because this configuration is considered to be the safest arrangement for guiding and controlling the movements of standing spectators, it is also the principal method by which ground management can aim to achieve the highest permissible capacity levels for a standing area.

For existing construction: at all sports grounds where standing accommodation is already provided, consideration should be given to the conversion of existing standing areas so that they incorporate a continuous crush barrier configuration between radial gangways. An example of a continuous crush barrier configuration is illustrated in Diagram 11.3.

As stated in Section 2.8 of the Green Guide, provided that the strengths of the continuous crush barriers are appropriate for the angle of slope and the spacings between the crush barriers, and the standing area is both in good condition and well stewarded, there should be no reduction in the calculation of its available viewing area, nor of its (P) and (S) factors, nor of its appropriate density, which should be the maximum of 47 persons per 10 square metres (as explained in Section 2.9 of the Green Guide).

Worked Example 1 in Annex A of the Green Guide illustrates how a continuous crush barrier configuration results in a higher capacity than a standing area of an identical size but with a non­ continuous configuration (as shown in Worked Example 2 of the Green Guide).
