(C) What types of permits can be obtained; and
(D) How to apply for a permit.
(2) The purpose of a permit is to provide notice to the Division that an employer will undertake permit-required activity and to allow the Division an effective means of ensuring that the proposed permit-required activity will be performed safely.
(3) There are two types of permits: Project Permits and Annual Permits. Both types are defined below in subsection (b) and explained in subsections (c), (d), and (e).
(4) The Permit application process is explained in section 341.1.
(b) Definitions. The following definitions apply to this article:

(2) “Climbing a fixed tower crane” means altering the height of the revolving section of the crane by adding or removing tower sections with the use of a climbing frame.
(3) “Conduct permit-required activity” means either:
(A) Engage in permit-required activity by having employees who actually perform the activity; or

Mechanical screens, antennas, chimneys, flag poles, and similar attachments are not to be considered in determining the height of a structure.
(6) “Hold a project permit” or “Hold an annual permit” means to have a valid applicable permit which was obtained prior to the start of work. In the case of underground use of a diesel engine in a mine or tunnel the permit shall be obtained prior to placing the engine in the mine or tunnel.
