Working with high-rise structures is as dangerous as working as a military officer in Iraq.
The risk is always present when working with high-rise structures. The transfer of construction materials from the ground up to the working floor is not as easy as you think. The pulley system that you are using must be strong and reliable to avoid any untoward accidents that may happen. In the same manner, the lowering of unused construction materials from the working floor down to the ground imposes the risk of getting hit on the head. Despite of the presence of your hard hat, excessive weight could break it and can cost you your own life.
