Safety glass usually refers to various glass types that have been strengthened or reinforced in some way to make them less susceptible to breakage or shattering, and make them safer when they are broken. Safety glass should not splinter into large shards when smashed. It may also be referred to as security glazing.

= Building Regulations =

Part N of the Approved Document deals with the requirements for safety glass. It requires safety glass to satisfy one of the following conditions:

* Where people moving in or about the building are likely to come into contact or impact the glass.
* If broken on impact, the glass should break in a way which is unlikely to cause injury.
* Resist impact without breaking.
* Be shielded or protected from impact.

In non-domestic applications, where glazing is transparent, it should incorporate features e.g markings, transfers etc, which make it apparent to people who are likely to impact it when moving in or about the building.
