(2) The employer must require employees to adhere to acceptable conditions for access, prior to climbing the tower at heights above four feet.

(3) Prior to employees being exposed to elevations above four feet, the employer must ensure that 100 percent fall protection systems compatible with the tasks assigned are provided, used, and maintained as required in this chapter and in accordance with the manufacturer's specifications.

(4) In addition to the requirements of WAC 296-32-24005 (5) through (7), all of the following must occur prior to employees climbing the tower at heights above four feet:

(ii) The documentation must be maintained on-site while work is being performed.

(iii) The documentation must include the date of the planning and inspection, the name of the competent person performing the planning and inspection, and the site location.

(b) All climbing facilities must be visually inspected daily at the tower base by a competent person for rust, corrosion, deterioration, structural, mechanical, or other hazards on the climbing facilities that could lead to death or injury of an employee in the performance of their duties. Additionally, the climbing facilities must be visually inspected for these items as the employees ascend to the elevation point where work is being performed. If any such hazard is identified during this inspection, employees must not use the climbing facility until such hazards are abated.

(c) Components of a fall protection system (including anchor points) and the fall protection equipment used by employees must be compatible with one another.

(d) Employees must use engineered anchor points or anchor points designated by a competent person.

(5) An employer must comply with the requirements of this section in one of the following ways:

(a) Require employees to use the 100 percent fall protection systems.

(b) If the fall protection systems described in this section are not present or do not meet the manufacturer's specifications, the employer must not permit employees to climb the tower at heights above four feet unless an alternative means of access to the work area is used such as an aerial lift, elevated work platform or other engineered systems.

(6) Positioning device system specifications. Positioning device systems must be used in conjunction with 100 percent fall protection systems and their use must conform to the following provisions:

(a) Positioning harnesses or full body harnesses must be used.

(b) Positioning devices must be rigged to prevent an employee from a free fall greater than two feet.

(c) Positioning devices must be secured to an anchorage capable of supporting at least twice the potential impact load of an employee's fall or three thousand pounds (13.3 kN), whichever is greater.

(d) Connectors must be drop forged, pressed or formed steel, or made of equivalent materials.

(e) Connectors must have a corrosion-resistant finish, and all surfaces and edges must be smooth to prevent damage to interfacing parts of this system.

(f) Connecting assemblies must have a minimum breaking strength of five thousand pounds (22.2 kN).

(g) D-rings and snap hooks must be proof-tested to a minimum tensile load of three thousand six hundred pounds (16 kN) without cracking, breaking, or taking permanent deformation.

(h) Snap hooks must be a locking type snap hook designed and used to prevent disengagement of the snap hook by the contact of the snap hook keeper by the connected member.

(i) Reserved.

(j) Unless the snap hook is designed for the following connections, snap hooks must not be engaged:

(i) Directly to webbing, rope or wire rope;

(ii) To each other;

(iii) To a D-ring to which another snap hook or other connector is attached;

(iv) To a horizontal lifeline; or

(v) To any object which is incompatibly shaped or dimensioned in relation to the snap hook such that unintentional disengagement could occur by the connected object being able to depress the snap hook keeper and release itself.

(7) Vertical lifelines.

(a) All employees suspended from a boatswain's chair or rope descent system must use an independent fall arrest system where the fall arrest anchorage is separate from the suspension system anchorage.

(b) All employees must be connected at all times to the fall arrest system while they are suspended.

(c) All rope used for suspended personnel must have a minimum breaking strength of five thousand pounds for each employee.

(d) Rope used for suspended personnel must not be used for material handling.

(e) The design of a descent control mechanism must prevent the device from causing an uncontrolled descent.

(f) The design of the manual descent device must permit operation only when rigged in the correct manner.

(8) Self-rescue devices. Self-rescue devices are not a fall protection system. Self-rescue devices used to self-rescue after a fall must meet the following requirements:

(a) Use self-rescue devices according to the manufacturer's instructions; and

(b) Self-rescue devices must be addressed by the fall protection work plan.

(9) When working from an aerial lift/crane basket:

(a) Employees must maintain 100 percent fall protection;

(i) When accessing the tower/structure from the aerial lift/crane basket the employee must first tie-off to the tower/structure; and

(ii) After tying-off to the tower/structure the employee must then immediately unhook from the aerial lift/crane basket and access the tower.

(b) Employees must maintain 100 percent fall protection:

(i) When accessing the aerial lift/crane basket from the tower/structure the employee must first tie-off to the aerial lift/crane basket; and

(ii) Then immediately access the aerial lift/crane basket; and

(iii) Then immediately unhook from the tower/structure.

(10) Ladder safety systems and related support systems for climbing facilities that are used by employees as a means of 100 percent fall protection must conform to all of the following criteria:

(a) Prior to climbing the structure, a competent person must ensure that the ladder safety system has been inspected for proper operation and that all components used with the ladder safety system are compatible.

(b) To perform an inspection, the competent person must do all of the following:

(i) Approach the ladder at the base and connect to the functional safety climb system.

(ii) Attach to the base of the fall arrest system. If the attachment point is above six feet, then 100 percent fall protection must be used. The 100 percent fall protection must be attached to an alternate approved anchorage point.

(iii) Forcibly engage the device without letting go of the ladder.

(iv) If the device does not function properly, employees must not use the device until it functions properly.

(c) If a climbing facility is obstructed, inhibiting the effective use of the ladder safety system, an alternative means of 100 percent fall protection must be used that is at least as effective as the types of fall protection described by this chapter.

(11) Fall protection work plan. The employer must develop and implement a written fall protection work plan including each area of the work place where the employees are assigned and where fall hazards of ten feet or more exist.

(a) The fall protection work plan must include, but not be limited to:

(i) Identify all fall hazards in the work area;

(ii) Describe the method of fall arrest or fall restraint to be provided;

(iii) Describe the proper procedures for the assembly, maintenance, inspection, and disassembly of the fall protection system to be used;

(iv) Describe the proper procedures for the handling, storage, and securing of tools and materials;

(v) Describe the method of providing overhead protection for employees who may be in, or pass through the area below the worksite;

(vi) Describe the method for prompt, safe removal of injured employees; and

(vii) Be available on the job site for inspection by the department.

(b) Prior to permitting employees into areas where fall hazards exist the employer must ensure employees are trained and instructed in the items described in this section.
