Operating environment

Danger zone: The "danger zone" refers to the area in which people are put at risk by
the travel or lifting movements of the industrial truck or of its load-handling equipment
(such as the forks or attachments, for example) or by the loads to be transported. It
also includes the possible impact zone of falling loads or falling or lowering
attachments.
Qw W
Unauthorized people must be asked to leave the danger zone. The driver
must indicate the possible development of a hazard situation for people by
sounding a warning signal. The industrial truck must be stopped immediately
if people do not leave the hazard zone, even though requested to do so.
The owner is responsible for classifying the atmosphere or hazard zones in
accordance with ANSI/NFPA 505.
The industrial trucks used in hazard zones and the batteries used there must carry
appropriate approval and satisfy the requirements of ANSI/NFPA 505.
Industrial trucks and their areas of use must be labeled in accordance with ANSI/
NFPA 505.
Braking distance: The braking distance of a powered industrial truck depends on
many factors, including traffic in the form of other industrial trucks and pedestrians,
the available space, the nature of the ground, and the stability of the load(s).
Particular care is required in situations where the environmental conditions have
changed. Changes to the weather, the ground surface or the application can have a
negative effect on the braking distance, so the maximum speed, the braking settings
and/or the operation of the industrial truck must be adjusted accordingly.
Gangways and obstacles: Permanent gangways, travel ways or passages and
floors must be marked appropriately in accordance with ANSI Z535.2.
Areas to which access by industrial trucks is not permitted must also be indicated and/
or marked.
In areas to which access is permitted, the area needed for the industrial truck and its
load and the space required for turning and maneuvering must be clearly marked.
Automatic doors and blind corners must be fitted with appropriate acoustic and/or
visual warning systems to indicate an approaching industrial truck or the operation of
the door. Passive devices – such as mirrors – are also recommended.
A distance of at least 1.5 ft (450 mm) must be maintained between obstacles and
freely moving industrial trucks (including load). All other areas with limited space must
be closed to industrial trucks and be clearly identified by signs, markers, light signals,
or other means.
– Automated industrial truck guidance systems must not pass through gangways
used frequently by pedestrians if the opening is not wide enough to allow people to
stand outside the guide path. The opening and closing of non-motorized doors
should be accompanied by a warning signal to warn people in the vicinity of the
gangway to keep away.
– To avoid the risk that a fire door cannot be completely closed, the industrial truck
responds to an appropriate signal – from a limit switch and/or a heat sensor, for
example – and stops ahead of the fire door.
