Safety glasses A Grade in Melbourne
The use of monolithic toughened glass more than 5000mm above finished floor height may be at risk of spontaneous breakage. Toughened glass glazed monolithically should be heat soaked unless a barrier exists which will revert the fragments from falling and reduce the risk of injury.
An awning or a balcony would be considered a barrier which suits this purpose. Please refer to AS1288 for further clarification.
