Technical Data

This is the technical data for the Lifeaxe Emergency Hammer for Double-Glazing.

Q. Is the "Lifeaxe Emergency Hammer for Double-Glazing" actually suitable for double glazed windows? I know the name suggests it is but I am looking for absolute verification.

A. The term “double glazed window” is a reference to a window which utilizes two pains of glass with a sealed air gap between. Double glazed windows are known to be difficult to break due to the air trapped between each pane (which allows the glass to flex and act as an air cushion) and this is most apparent towards the centre, however the edges of the glass adjacent to its frame are more rigid (especially the corners) and this is the area one should strike the glass to break it.

The Lifeaxe has been designed to penetrate both toughened and annealed (float) glass and is suitable for both vehicle and vertical building glazing. In the event two panes of glass are used (double glazed) the user would break the first pane then proceed to break the second pane. Instructions are supplied with every Lifeaxe and the purchaser should make themselves familiar with these on receipt and retain them for future reference.

Q. Can the emergency escape hammer break glass office doors?

A. Yes, as long as they are not wired safety glass.
