Preface
This is the second edition of CSA Standard B354.4, Self-Propelled Boom-Supported Elevating Work Platforms. It supersedes the previous edition published in 1982, under the title Boom-Type Elevating Work Platforms. The purpose of this Standard is to provide criteria for the design, manufacture, remanufacture, rebuild/recondition, testing, performance, inspection, training, maintenance, and safe operation of self-propelled boom-supported elevating work platforms.
With the objective of guarding against and minimizing the risk of injury to workers, the scope of this Standard has been expanded to provide additional information on safe operating procedures and training requirements. As well, the section on inspection and maintenance requirements has been enhanced to provide more guidance on the different types of inspections (daily, periodic, and annual). A new structural inspection requirement has been added to ensure that older machines or those that have sustained actual, suspected, or potential damage maintain their stability and structural integrity.
With respect to design and manufacture criteria, the Standard is closely harmonized with the equivalent ANSI Standard.
This Standard was prepared by the Technical Committee on Elevating Work Platforms, under the jurisdiction of the Strategic Steering Committee on Occupational Health and Safety, and has been formally approved by the Technical Committee. It will be submitted to the Standards Council of Canada for approval as a National Standard of Canada.
Scope and Purpose
1.1 Scope
This Standard applies to self-propelled boom-supported integral chassis elevated work platforms that have a platform capable of being positioned completely beyond the base and that are used to position personnel, along with their necessary tools and materials, at work locations. Self-propelled boom-supported elevating work platforms (aerial platforms) are power-operated with primary functions, including drive control from the platform. For the purpose of this Standard, self-propelled boom-supported elevating work platforms will be referred to as aerial platforms.
1.2 Purpose
The purpose of this Standard is to specify the minimum requirements for design, manufacture, remanufacture, rebuild/recondition, testing, performance, inspection, training, maintenance, and safe operation of aerial platforms to achieve the following objectives:
(a) the prevention of personal injuries and accidents;
(b) a uniformity in ratings; and
(c) an understanding by manufacturers, dealers, installers, maintenance personnel, operators, owners, and users of their respective responsibilities.
Aerial platforms are generally intended for use over level surfaces. Normally they are not insulated for use near electrically energized circuits, nor are they intended to be used in hazardous locations. For any aerial platforms intended for use around electrically energized circuits, see CSA Standard C225.
The operation of any aerial platform is subject to certain hazards that can only be protected against by having competent, careful personnel trained in the intended use, safe operation, maintenance, and servicing of this type of equipment.
1.3 Application
The design and manufacturing requirements of this Standard apply to those aerial platforms manufactured six months after the date of publication of this Standard. All other provisions of this Standard apply to both new and existing aerial platforms and become effective at the time of publication of this Standard.
1.4 Equipment not Covered
This Standard does not apply to
(a) vehicle-mounted aerial devices, such as those covered in CSA Standard C225;
(b) non-self-propelled elevating rolling work platforms, as covered in CSA Standard CAN3-B354.1;
(c) self-propelled elevating work platforms, as covered in CSA Standard CAN3-B354.2;
(d) mast climbing equipment, such as that covered in CSA Standard CAN3-B354.5;
(e) construction hoists used to raise and lower materials and personnel to different elevations, as covered in CSA Standards Z256 and CAN/CSA-Z185;
(f) mobile cranes, such as those covered in CSA Standard Z150;
(g) vehicle-mounted vertical lift devices, such as those covered in the ANSI/SIA Standard A92.7.
(h) vehicle-mounted bridge inspection and maintenance devices, as covered in ANSI/SIA Standard A92.8;
(i) permanently installed (nonmobile) elevating lifts used to transport personnel between different elevations; and
(j) firefighting equipment.
1.5 Terminology
In this Standard, “shall” is used to express a requirement, ie, a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Legends to equations and figures are considered requirements.
1.6 Measurement
The values given in SI (metric) units are the standard. The values given in parentheses are for information only.
