guide: glazing safety - part N »
In particular locations, glazing materials within doors or
associated screens must limit the risk of cutting or
piercing injuries in the event of breakage. Part N of the
Building Regulations identifies these ‘critical
locations’ and appropriate measures, including use of
safety glass as defined in BS 6206 : 1981.The 1998 (amended
2000) Edition of Approved Document Part N ‘Glazing
– safety in relation to impact, opening and
cleaning’ identifies critical locations for glazing
within doors and screens: these are shown in the diagram.
APPROVED DOCUMENT N, DIAGRAM 1,
CRITICAL LOCATION IN INTERNAL AND EXTERNAL WALLS

In these locations,
glazing should:
1) break safely, if at all or
2) be robust or in small panes or
3) be permanently
protected. |

These requirements are achieved, respectively, by:
1) compliance with test requirements in BS 6206 (that
follows)
2) use of inherently strong materials or
annealed glass (subject to thickness/area limits), or small
panes each no wider than 250mm and larger than 0.5m2
3)
an unclimbable, robust screen 800mm high from floor level
which prevents a 75mm diameter sphere coming into contact
with the glass.
