Design of glass structures. Glass selection relating to the risk of human injury. Guidance for specification | Status: Current

1 Scope (1) This document provides guidance for the development or improvement of rules deemed to help with the choosing of appropriate glazing for protection against injuries and falling, hereafter called “the Specifications”. The Specifications to be written or revised can be a national regulation, a national standard, recommendations from a professional association, requirements for a particular project, etc. (2) This document deals with the choice of the mode of breakage (see 5.2) with regard to the safety of people against:

• — the risk of injury in the event of a collision with a glazed element, e.g. a partition,
• — the risk of falling through or over a glazed element, e.g. a balustrade, and
• — the risk of accidental falling of glass fragments on people not having caused the breakage, e.g. an overhead glazing.

(3) These risks can be evaluated in the function of a normal use of the building or construction work. This includes use by the elderly, children and people with disabilities, but excludes deliberate risk taking. It presupposes a rational and responsible behaviour of the users or, in case of children, of those responsible for supervising them. (4) The information contained in this document can be used to define minimum glass configuration. It does not exempt from the verification according to CEN/TS 19100‑1 and CEN/TS 19100‑2 and where appropriate CEN/TS 19100‑3. (5) Safety against burglary, vandalism, bullet attack, explosion, exposition to fire and seismic actions are not covered in this document. Preventing these risks needs further appropriate requirements. (6) This document does not apply to the following glass products:

• — glass blocks and paver units;
• — channel-shaped glass.

(7) It also does not apply to the following applications:

• — escalators and moving walkway;
• — lifts;
• — accesses to machinery;
• — animal enclosures and aquariums;
• — greenhouses and agricultural installations;
• — temporary scaffolds.
