Sheeting means the members of a shoring system that retain the earth in. position and in turn are supported by other members of the shoring system. See. figure 2.0. Shield (Shield system) means a structure used in an excavation to withstand. cave-ins and which will protect employees working within the shield system.
For very noisy environments, multiple shielding layers are often used. Most common is using both a foil and a braid. In multiconductor cables, individual pairs are sometimes shielded with foil to provide crosstalk protection between the pairs, while the overall cable is shielded with foil, braid, or both.ut braided shields do not provide 100% coverage. They allow small gaps in coverage. Depending on the tightness of the weave, braids typically provide between 70% and 95% coverage. When the cable is stationary, 70% is usually sufficient.
