Break Glass in Emergency


“In Case of Emergency, Break Glass ” – We’ve all seen the signs but have you wondered what would happen if you DID have to break the glass?

Breaking real glass sounds counter-intuitive – it is! That is why other solutions have been developed which are safer, easier and more suitable to break glass emergency equipment.

The type of material you choose will depend on the type of station and its location.

Types of Break Glass


Our flagship product, Safeglass, is the only material specifically designed for break glass use. It breaks into pieces that do not hold an edge and is therefore much safer to break than glass. The pieces can be safely cleared away if it is broken by accident.

Safeglass is used throughout the rail and bus industry. You will find it in hammer boxes, emergency door exits, first aid kits and in the driver’s cab.

You will also find it in fire alarms, oxygen shut off valves (in hospitals) and key boxes.

Toughened glass

This is tough to break as the name suggests but when it does break, it forms small cubes of glass which are much safer than float glass.

This is often used for oxygen shut off valves and fire extinguishers in public transport. Whilst we do supply this kind of glass, we do not recommend it as it can be difficult to break without a tool.


Plastic is normally too tough to be used as break glass but it can be weakened to make it break over certain areas.For example, grooves can be cut into the plastic or a composite part can be made with a breakable material being held in place by a stronger material.

This is safer than toughened glass and real glass but can be awkward to weaken.

We accasionally provide this solution in some situations. Our preference is always Safeglass but this is not possible for everything.
