2 SLAC Environment, Safety, and Health Manual Chapter 47: Mobile Elevating Work Platforms (MEWP) 1 Overview Authorized SLAC personnel and subcontractors may use mobile elevating work platforms (MEWPs) to raise personnel, equipment, and working materials to elevated work areas. MEWPs (including scissors lifts, articulating boom aerial devices, and elevating platforms) offer flexible and versatile access to elevated locations. When work must be performed for extended periods of time at elevation and there is no guarded, fixed work surface available, it is generally appropriate to use a MEWP. When a MEWP is properly used, it can provide a useful working platform at heights, and is often safer than ladders or other access equipment. This chapter describes the minimum requirements for safely operating MEWPs at SLAC. 1.1 Hazards/Impacts The misuse of MEWPs can result in property damage, severe injury, or death. Accidents associated with MEWPs include tip/ roll-overs, collapses, or personnel being thrown from the basket. The risk of falling or being pinned by a nearby structure is increased by an impact, ground movement, improper maneuvering by the operator, or failure of an equipment component that is critical to the stability of the MEWP. Contact with electrical lines or equipment is a major hazard associated with MEWPs. 2 Scope The MEWP program and its requirements apply to all personnel participating in operations involving MEWPs at SLAC, as defined in Section 4, Definitions. If use of a MEWP is required by subcontractors, their work is governed by their companies programs. Subcontractors will provide proof of adequate programs, including training and equipment maintenance. 2.1 Exemptions Excluded from this chapter are requirements for scaffolds, industrial lift trucks (forklifts), ladders, ladder stands, cranes, or fixed or permanent elevated work platforms. 3 Standards The MEWP program has adopted the following standards: Title 8, California Code of Regulations, Division 1, Chapter 4, Subchapter 7, General Industry Safety Orders 47-2 SLAC-I-720-0A29Z-001-R023 8 July 2006

The building/facility/area managers of the location where the MEWP work is taking place will authorize the work, and the operator s supervisor and the MEWP custodian will authorize the individual s use of the MEWP by verifying the individual is qualified for that class of device. Operators must stay within the scope of the authorization or obtain additional authorization SLAC-I-720-0A29Z-001-R023 8 July 2006

5 Chapter 47: Mobile Elevating Work Platforms (MEWP) SLAC Environment, Safety, and Health Manual Electrical Hazards Because of the hazards posed by electrical systems, MEWP work in the proximity of unprotected or exposed electrical systems must be authorized by the building/facility/area manager of the location where the MEWP work is taking place, utilize an insulated MEWP, and must comply with SLAC electrical work requirements as outlined in Chapter 8, Electrical Safety. An energized work permit detailing the safety precautions and procedures must be obtained with directorate approval. Work is considered in proximity to electrical systems if the work is inside the limited approach boundary or arc flash boundary, whichever is greater, of the electrical systems (see Chapter 8 for guidance on determining these boundaries) Equipment MEWPs must be designed and manufactured in accordance with the applicable ANSI standard and marked, stored, and maintained following the requirements of this chapter. Only MEWPs that pass a pre-use safety inspection and meet applicable requirements are permitted to be operated at SLAC. The inspection must be conducted by an operator and documented on a MEWP: Pre-use Inspection Checklist (see Section 6, Exhibits ), which must be returned with the device to the MEWP custodian. If a MEWP does not pass this pre-use inspection, the operator must tag it Danger Do Not Operate, remove it immediately from service, and contact the custodian Storage MEWPs should be stored away from high traffic areas and effectively barricaded where necessary. The baskets should be positioned in such a way as to prevent unauthorized access to the basket and controls. During stormy or windy conditions, the basket should be fully lowered to prevent upset. The keys should not be left in stored MEWPs Maintenance MEWP custodians will establish and follow a program of regular maintenance to ensure that MEWPs remain in a safe operating condition. The custodian will ensure maintenance records are kept and available upon request. Only authorized personnel, that is, employees of SLAC Fleet Services or of a third-party approved by it, will be permitted to maintain or repair MEWPs. When service occurs that requires entry of any body part into a danger zone within the equipment, or unexpected startup or energizing of the MEWP could cause injury, maintenance personnel will first isolate hazardous energies as required by the SLAC Lock and Tag Program for the Control of Hazardous Energy Marking Each MEWP will have a conspicuously displayed legible plate or other legible marking verifying that it is designed and manufactured in accordance with the applicable ANSI standard. See Section 6, Exhibits, 6 SLAC Lock and Tag Program for the Control of Hazardous Energy (SLAC-I-730-0A10Z-001), 8 July 2006 SLAC-I-720-0A29Z-001-R

Additional labeling requirements are provided in Section 6, Exhibits, MEWP: Pre-inspection Checklist Leased or Rented Equipment Prior to bringing a leased or rented MEWP onto SLAC property, the MEWP custodian will verify the MEWP meets the minimum requirements of this program Use of Fall Protection Equipment For aerial devices (for example, articulating boom lifts and Genie/JLG lifts), approved fall restraint or arrest systems must be used by personnel while they are within the basket of the device, and such systems will be connected to an approved anchorage point provided within the basket. For vertical-only work platforms such as scissor lifts, a fall arrest system will be neither worn nor used by personnel while they are working properly within the guardrails of the lift unless there are manufacturerinstalled rated anchorage points within the basket, and the manufacturer recommends the use of a fall arrest system. Wearing approved fall restraint or arrest equipment does not permit the wearer to stand on the basket s railings, use planks or other such methods to gain a higher elevation, or climb out of the basket onto another surface. Equipment designed by the manufacturer for exiting at heights must comply with all pertinent regulations and SLAC policy. For details on fall protection systems and requirements, refer to Chapter 45, Fall Protection Personnel Operators Operators must be properly trained, qualified, and licensed (refer to Section 5.3, Training ) in order to use a MEWP, and they must use fall protection as required. While operating a MEWP, operators will carry proof of authorization and operator training, such as an operator s wallet card from an approved SLAC MEWP training course or other acceptable outside training firm Custodians Custodians of MEWPs must be trained at a minimum to the level of a qualified operator Spotters Safety spotters are required during the use of MEWPs when there is a potential for operator injury due to physical contact with facility systems or structures. A safety spotter may be another co-worker located on the work platform or on the ground depending on the area to be observed during movement. In many cases the spotter can be a worker who is performing other duties, but can be called on to observe during vertical or horizontal movement and need not be an additional person with the sole purpose of spotting SLAC-I-720-0A29Z-001-R023 8 July 2006

13 MEWP: Safe Operating Requirements Department: Chemical and General Safety Program: Mobile Elevating Work Platforms Owner: Program Manager, Scott Blankenship Authority: ES&H Manual, Chapter 47, Mobile Elevating Work Platforms MEWP Operators MEWP operators will comply with the following: Operators will have their license in possession while operating MEWPS. In addition to required MEWP training, operators must have completed ES&H Course 200, Fall Protection Authorized Person, 1 training if they are to use extensible or articulating boom aerial devices. MEWPs will be inspected at the beginning of each shift in use. Personnel will document the pre-use inspection on the MEWP Pre-use Inspection Checklist (or other approved checklist) and will keep the checklist in a protected location in the MEWP. Personnel are not permitted to climb outside the protective guardrails of any elevated fixed platform, elevating work platform, or aerial device. No person will sit or stand on railings, or use planks or boards to gain access to a higher elevation or to climb off the MEWP. Most MEWPs are intended for use as work platforms and not as a means of access to or egress from elevated levels. Stairs, ladders, and stepladders should be used to gain access to elevated work locations. MEWP Control Panels MEWP control panels require dual activation by the operator to activate the directional (horizontal or vertical movement) controls. Time-delay ramping feature activation controls are not permitted. Authorized ES&H personnel must approve MEWP controls other than A joystick equipped with an enable switch that has a time-out function of 10 seconds or less (non-locking or spring loaded) A joystick with guarded trigger mechanism A joystick with a separate enable switch (continuously pressed) A joystick with a pull-up trigger A foot pedal + joystick MEWPs All controls must be clearly labeled. The operator s manual will be kept in a weather-resistant storage location on the MEWP July 2006 SLAC-I-730-0A21S-008-R000 1 of 2

14 MEWP: Safe Operating Requirements The mid and top chains, railing, and gate enclosures must be in the closed position before elevating the device. To prevent inadvertent movement of the MEWP after it has been moved into the final work position, the control panel will be de-energized (turned off). The maximum operating weight capacity will not be exceeded (including personnel, equipment, supplies, and tools). Personnel will not work on MEWPs when exposed to high winds, storms, or when the equipment or materials are covered with ice or snow. MEWPs will not be used as cranes. No MEWP will travel with personnel in the basket while it is elevated, unless the equipment is designed for this activity and operations are conducted in accordance with all applicable regulations and standards. MEWPs will be operated on stable, flat, and structurally sound flooring or ground only. Where moving vehicles are present, the work area will be marked with warnings such as flags or roped off areas, or other effective means of traffic control will be provided. Unstable objects such as barrels, boxes, loose brick, tools, debris, will not be allowed to accumulate on the floor of the MEWP. Proper ventilation must be provided when operating internal combustion equipment indoors. If there are any questions about the air quality, stop work and contact a SLAC industrial hygienist. Maintenance will be done by SLAC Fleet Services or an approved service provider. 8 July 2006 SLAC-I-730-0A21S-008-R000 2 of 2
