In 1976, in Cleveland Ohio, CAL-OSHA performed an impact safety test on several glass products by mounting the windows into a box placed below a slag pit trough and poured molten slag onto the different products.
The red-hot steel slag can still be seen all around the box. Of all ten products tested, MacPherson & Company’s SAFE-SHIELD composite glass was the only product that passed this CAL-OSHA test.
At MacPherson Glass we aim to pioneer advancements in Engineered Safety Windows that provide unparalleled protection for Industrial Workers
