(t) Digger derricks only when used for augering holes for poles carrying electric or telecommunication lines, placing and removing the poles, and for handling associated materials for installation on, or removal from, the poles, or when used for any other work subject to chapter 296-45 WAC, Electric power generation, transmission, and distribution, or chapter 296-32 WAC, Safety standards for telecommunications. Cranes other than digger derricks when used for activities that are covered under chapter 296-45 WAC, Electric power generation, transmission, and distribution, or chapter 296-32 WAC, Safety standards for telecommunications are not exempt;

(u) Powered industrial trucks (forklifts) except when configured to hoist and lower (by means of a winch or hook) and horizontally move a suspended load;

(v) Flash-butt welding trucks. Flash-butt welding trucks or other roadway maintenance machines not equipped with any hoisting device other than that used to suspend and move a welding device or workhead assembly. For purposes of this subsection (4)(v), the terms flash-butt welding truck and roadway maintenance machine refer to railroad equipment that meets the definition of "roadway maintenance machine" in 49 C.F.R. 214.7, and is used only for railroad track work.

(5) Digger derricks that do not meet the exemption criteria in subsection (4)(t) of this section must comply with all of chapter 296-155 WAC, Part L.
