PROPOSED RULES

DEPARTMENT OF

LABOR AND INDUSTRIES

[ Filed April 18, 2006, 9:30 a.m. ]

Original Notice.

Preproposal statement of inquiry was filed as WSR 05-17-104.

Title of Rule and Other Identifying Information: Chapter 296-24 WAC, Part J-3, Powered platforms; chapter 296-155 WAC, Part J-1, Elevating work platforms; and chapter 296-869 WAC, Elevating work platforms.

Hearing Location(s): Department of Labor and Industries, Auditorium, 7273 Linderson Way S.W., Tumwater, WA, on May 31, 2006, at 9:00 a.m.

Date of Intended Adoption: July 7, 2006.

Submit Written Comments to: Jim Hughes, Project Manager, P.O. Box 44620, Olympia, WA 98507-4620, e-mail hugw235@lni.wa.gov, fax (360) 902-5619, by noon, June 9, 2006.

Assistance for Persons with Disabilities: Contact Kimberly Johnson by May 24, 2006, at (360) 902-5008, TTY (360) 902-4645, or e-mail rhok235@lni.wa.gov.

Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: Portions of chapter 296-24 WAC, Part J-3, Powered platforms and chapter 296-155 WAC, Part J-1, Elevating work platforms, have been rewritten for clarity and usability, while making housekeeping revision. Existing rules will be combined into a single book titled elevating work platforms, chapter 296-869 WAC.

Reasons Supporting Proposal: Rewritten rules will be easier to use and understand for both employers and employees.

Statutory Authority for Adoption: RCW 49.17.010, 49.17.040, 49.17.050, and 49.17.060.

Statute Being Implemented: Chapter 49.17 RCW.

Rule is not necessitated by federal law, federal or state court decision.

Name of Proponent: Department of labor and industries, governmental.

Name of Agency Personnel Responsible for Drafting: Tracy Spencer, Tumwater, Washington, (360) 902-5530; Implementation and Enforcement: Stephen M. Cant, Tumwater, Washington, (360) 902-5495.

No small business economic impact statement has been prepared under chapter 19.85 RCW. RCW 19.85.030 (1)(a) requires a small business economic impact statement (SBEIS) only when a rule will "impose more than a minor cost on businesses in an industry." An analysis of the proposed rule reveals that in addition to not imposing new costs on businesses, these revisions will make WISHA rules easier for employers and employees to understand and use, and thus save time and resources. Therefore, no SBEIS is required.

A cost-benefit analysis is not required under RCW 34.05.328. There are no costs to assess within these proposed rules.

WAC 296-869-60030   Elevating and lowering the platform.  

You must:

Have the operator make sure all of the following are done before each elevation of the platform:

The elevating work platform is on a surface that is within the limits specified by the manufacturer

Outriggers, stabilizers, extendable axes, or other stability enhancing means are used as required by the manufacturer

Guardrails are installed and access gates or openings are closed per the manufacturer's instructions

The load and its distribution on the platform and any platform extension does not exceed the manufacturer's rated capacity for the configuration being used

There is adequate clearance from overhead obstructions

The minimum safe approach distance (MSAD) to energized power lines and parts listed in Table 6, Minimum Safe Approach Distance, is maintained

All persons on the platform are wearing fall protection devices and other safety gear if required

Prevent rope, electric cords, hoses and similar objects from becoming entangled with the platform.

Have the operator make sure the area is clear of personnel and equipment before lowering the platform.

Remove all personnel from a platform that has been caught, snagged, or otherwise prevented from normal motion before attempting to free it using ground controls.

Note: If possible, reverse the platform controls to free a platform that is caught, snagged, or otherwise prevented from normal motion by an adjacent structure or other obstacle.

Table 6
Minimum Safe Approach Distance

Voltage Minimum Safe Approach Distance
Less than 300 volts (insulated lines) 3 feet (0.9 m)
Less than 300 volts (uninsulated lines) 10 feet (3.1 m)
300 volts to 50 kv 10 feet (3.1 m)
More than 50 kv 10 feet (3.1 m) + 0.4 inches (1.0 cm)

for each 1 kv over 50 kv
