Mobile Elevating Work Platforms
(MEWPs)
Issue Date: 10/16/23
Revision Date: 10/16/23
Reference: A-12
Large or excessive amounts of material, excluding tools, shall not be transported in a MEWP. Other material
lifts would be necessary for such activities. Load limits specified by the manufacturer shall not be exceeded.
MEWPs that can operate horizontally shall set brakes and outriggers, when used, be positioned on pads or a
solid surface, and chock wheels before using on an incline.
Boom and Ladder Lift Units
Before ladder trucks and tower trucks are moved from site to site, the aerial ladders shall be secured in the
lower traveling position by the locking device above the truck cab, and the manually operated device at the base
of the ladder, or by other equally effective means (e.g., cradles which prevent rotation of the ladder in
combination with positive acting linear actuators).
A mobile elevating work platform may not be moved when the boom is elevated in a working position with
personnel in the basket, except for equipment that is specifically designed for this type of operation.
Articulating boom and extendible boom platforms, primarily designed as personnel carriers, shall have both
platform (upper) and lower controls. Upper controls shall be in or beside the platform within easy reach of the
operator. Lower controls shall provide for overriding the upper controls. Controls shall be plainly marked as to
their function. Lower-level controls shall not be operated unless permission has been obtained from the worker
in the lift, except in case of emergency.
MEWP devices that are insulated shall not be altered in any manner that might reduce its insulating value. The
insulated boom of a MEWP shall be regularly maintained and certified to ensure the continued insulating
properties.
Before moving a MEWP for travel, the boom(s) shall be inspected to see that it is properly cradled and outriggers
are in stowed position.
Modifications
MEWPs may be "field modified" for uses other than those intended by the manufacturer, provided the
modification has been certified in writing.
Overhead Lines
Any vehicle or mechanical equipment capable of having parts of its structure elevated
near energized overhead lines will be operated so that a clearance of 10 ft. (305 cm) is
maintained. If the voltage is higher than 50kV, the clearance will be increased 4 in. (10
cm) for every 10kV over that voltage. See Table A
