NFPA 70E Annex F Risk Assessment and Risk Control Sections F.3 and F.4 provide insight to how design concepts and system upgrades can reduce or eliminate electrical hazards. Table F.3, The Hierarchy of Risk Control Methods, lists six Risk Control Methods; the lower the number in this table, the greater the effectiveness in reducing the risk. The design concepts and upgrades discussed pertain to (1) elimination, (2) substitution, and (3) engineering controls in the hierarchy of Table F.3. Safety by design is considered to have less effectiveness than item (6) PPE in the Hierarchy of Risk Control Methods.

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
