Glass can be a hazard at schools if it breaks. Boards need to manage this hazard, including knowing what kind of glass to install and what standards you need to comply with.

Keeping people safe from the hazards of broken glass is part of your overall health and safety responsibilities. We recommend you review your school’s health and safety systems.
This will help you meet the requirements of the Health and Safety at Work Act 2015 — NZ Legislation website(external link).
Give the information on this page to your project manager and contractors fitting new or replacement glass at your school.
|Grade A safety glass||
You must use Grade A safety glass in these situations:
Where a window begins less than 1.6 metres from the ground, and goes higher than 1.6 metres, take the safety glazing to the top of the window or to the next transom (the horizontal cross piece of the window).
Where the window begins at ground level and goes up to 2 metres or higher, use safety glazing unless the glass is protected by mesh, guards or some other similar protection.
|Other glass||In all other cases, all glass should be installed to the New Zealand Standard 4223.3:2016(external link)
Note that some glazing may be fire rated. In these instances, ensure the integrity of the fire protection remains compliant with regulations.
|Double glazing||You may wish to upgrade your windows to double glazing. If you’re using aluminium, make sure you use frames that are thermally broken or insulated. Aluminium is a good conductor of heat so if it's cold outside, the frames will be cold inside and suffer from condensation.|
|Anti-graffiti film||A common issue for schools is the scratching or etching of glass by vandals. One solution is to install an anti-graffiti film. This is an optically clear protective film that is applied to exterior glazing to prevent glass damage.|
You should check the glass in your school regularly. If there are changes to your school, such as new courts being built, this could introduce new hazards and ordinary glass may have to be replaced with safety glass.
Pay for glass in new buildings or alterations out of your project budget, for example, an upgrade project paid for with 5YA funding.
To pay for replacing broken glass or to install new safety glass, use your school’s Property Maintenance Grant PMG funding.
