Section 7: Maintainability and Serviceability
Section Indicator Figure
7.1 Minimum lighting level in routine maintenance areas is required where
the operator has to read information, use a hand tool, or make a
connection. This provision can be met by providing integral lighting or
portable lighting which can be temporarily attached such that it does not
have to be hand held.
Acceptance criterion: minimum 300 lux (30 fc)
7.2 Full Body Clearance
NOTE A: Forward horizontal distances are measured away from the
equipment or obstruction for body clearance in a given
posture.
NOTE B: Clearances should be provided based on the nature of the
tasks performed in the designated area.
NOTE C: When determining the appropriate working space required
for a given task, first define the working height. Once this is
known, determine the posture(s) associated with the working
height and use Sections 7.2.1–7.2.9 to determine the
minimum working area for that posture.
NOTE D: Minimum working heights are used to determine postures for
sustained activities (tasks which take longer than 5 minutes
or have a total duration of greater than 1 hour per shift).
7.2.1 Any posture: upper body clearance (shoulder width)
A: Acceptance criterion: minimum 610 mm (24 in.)
