Temporary FP Systems
Although double-lanyard systems remain a seemingly obvious answer for moving horizontally on many present structures without the provision of horizontal lifelines, their use is cumbersome. An interesting variant used in Japan employs a simpler system that includes a keybox attached to the worker’s belt. One lanyard key is inserted and remains attached until a second lanyard key is inserted in another opening. This action ejects the first lanyard key and allows unhindered transfer past obstructions or supports while ensuring continuous protection.
