Why Check ?• You need to be sure that your home is a Safe Environment.

• It is a legal requirement to install safety glazing in Critical Locations. Checking could save lives.

• Approved Document N (Glazing - Protection against impact) of the Building Regulations in Englandand Wales provides guidance for safety glazing.

• BS 6262-4:2005 provides details of safety glazing requirements.

What you need to do• Identify areas in your home that are considered to be ‘critical locations’ (see Figure 1 - over page).

• You must then check that these critical locations have safety glazing material installed.

• If safety glazing material has been installed, there will be visible markings you can check.

All safety glasses must be visibly marked on the glass. If the ‘visible markings’ on the safety glazingmaterial is not clear or you have any concerns about whether the safety glazing has been installed tothe correct standard, you should go back to the original window installer and seek advice.If you are not happy with their response, you should contact FENSA www.fensa.org.uk

Safety Glazing is:• A glass or glazing product which conforms to the relevant European glazing standard

e.g. BS EN 12150 or BS EN 14449 or BS EN 14179.

• The glass has also been tested against the European standard for BS EN 12600 for safety impact.This means that on impact the glass does not break or breaks in a way unlikely to cause serious injury.
