8. Responsibilities of the Owners and Users
8.1 General Responsibilities. Each owner or user shall comply with the requirements
of this section.
The following responsibilities pertain to owner and user inspection, testing, mainte-
nance and modification. These activities shall be performed by qualified person(s).
8.2 Inspection and Testing Classifications.
8.2.1 Initial Inspection and Test. Prior to initial use, all new or modified mobile
units shall be inspected and tested to ensure compliance with the provisions of this
standard. Verification by the manufacturer, the installer or an equivalent entity(s),
meets this requirement.
8.2.2 Regular Inspection and Tests. The inspection procedure for mobile units is
divided into two classifications based upon the intervals at which inspections and
test shall be performed. Safe intervals shall be set by the user based on the recom-
mendations that shall be supplied by the manufacturer.
Such intervals are dependent upon component function and exposure to wear, dete-
rioration and other agents which adversely affect component life. Two classifica-
tions are designated:
(1) Frequent Inspection and Test: Daily to monthly intervals
(2) Periodic Inspection and Test: One to twelve month intervals
8.2.3 Frequent Inspection and Test. Items determined by the user based on rec-
ommendations by the manufacturer for each specific aerial device shall be inspected
for defects.
Inspection and tests referred to as critical in the manufacturer's manual shall be
strictly adhered to.
The following tests and inspections shall be performed by the operator once daily,
prior to first use:
(1) Operating controls and associated mechanisms for conditions interfering with
proper operation
(2) Visual and audible safety devices for malfunction
(3) Hydraulic or pneumatic systems for observable deterioration or excessive leak-
age
(4) Fiberglass and other insulating components of visible damage or contamination
(5) Missing illegible operational markings
(6) Electrical apparatus for malfunction, signs or excessive deterioration, dirt, and
moisture accumulation
Any suspected items shall be carefully examined and a determination made by a
qualified person as to whether they constitute a safety hazard. All unsafe items shall
be replace or repaired before use.
8.2.4 Periodic Inspection and Test. An inspection of the mobile unit shall be per-
formed at the intervals defined in 8.2.2 depending upon its activity, severity of ser-
vice, and environment, or as specifically indicated below. (These inspections shall
include the requirements of 8.2.3).
(1) Structural members for deformation, cracks or corrosion
(2) Parts, such as pins, bearings, shafts, gears, rollers, locking devices, chains,
chain sprockets, wire ropes, and sheaves for wear, cracks or distortion
(3) Hydraulic and pneumatic relief valve settings
(4) Hydraulic system for proper oil level
(5) Hydraulic and pneumatic fittings, hoses, and tubing for evidence of leakage,
abnormal deformation, or excessive abrasion
(6) Compressors, pumps, motors and generators for loose fasteners, leaks, unusual
noises or vibrations, loss of operating speed, and excessive heating
