1996-2, 2003-1, 2008-4, and 2011-4, MCL 445.2001, 445.2011, 445.2025, and 445.2030)

PART 32. AERIAL WORK PLATFORMS

R 408.43201 Scope.

Rule 3201. These rules apply to the construction, operation, maintenance, and inspection

of aerial work platforms with either manual or powered mobility as used in construction

operations as defined by 1974 PA 154, MCL 408.1001 to MCL 408.1094.

History: 1992 AACS; 2008 AACS.

R 408.43202 Equipment covered.

Rule 3202. (1) These rules apply to equipment that has a primary function of elevating

personnel, together with their tools and necessary materials, on a platform, which is

mechanically positioned. The units covered are described by the following American

national standards institute standards:

(a) ANSI standard A92.2, 2002 edition, "Vehicle-Mounted Elevating and Rotating Aerial

Devices," which is adopted by reference in R 408.43204a. This standard applies to vehicle-

mounted devices installed on commercial chassis and covers the following type of units

(See figure 1):

(i) Extensible boom aerial devices.

(ii) Aerial ladders.

(iii) Articulating boom aerial devices.

(iv) Vertical towers.

(v) A combination of any of the equipment specified in paragraphs (i) to (iv) of this

subdivision.

(b) ANSI standard A92.3, 2006 edition, "Manually Propelled Elevating Aerial Platforms,"

which is adopted by reference in R 408.43204a. This standard applies to work platforms

which are manually propelled, which are vertically adjustable by manual or powered

means, and which may be towed or manually moved horizontally on wheels or casters that

are an integral part of the work platform base. (See figure 2).

(c) ANSI standard A92.5, 2006 edition, "Boom-Supported Elevating Work Platforms,"

which is adopted by reference in R 408.43204a. This standard applies to all integral frame,

boom-supported elevating work platforms which telescope, articulate, rotate, or extend

beyond the base dimensions. (See figure 3).

Page 1

(d) ANSI standard A92.6, 1999 edition, "Self-Propelled Elevating Work Platforms,"

which is adopted by reference in R 408.43204a. This standard applies to self-propelled

vertically adjustable integral chassis work platforms. Such work platforms are power-

operated with primary controls for all movement operated from the platform. (See figure

4).

(2) Equipment adapted to elevating personnel with a primary function other than elevating

personnel, such as fork trucks or cranes, are not covered by these rules. Those types of

equipment are provided for in construction safety standards Part 10. "Lifting and Digging

Equipment," R 408.41001a to R 408.41099a and Part 13. "Mobile Equipment," R
