This is compounded by the wind entering the building allowing the building interior to pressurize, lifting the underside of the roof panels, resulting in the ...
Horizontal lifeline systems require careful engineering due to the specific nature of the structures they are designed for, ensuring safety in high-risk areas. [ 3 ] Lifeline wire has traditionally been available in 1/8" ( 3.175 mm) and 3/16" ( 4.763 mm) wire diameters, with a soft but durable vinyl coating increasing the effective diameters to ...
