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 requested 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, haulers and their areas of use must be labeled in accordance with
ANSI/NFPA 505.
Braking distance (slopes): When driving on a slope, the braking distance is longer
than on a horizontal surface. To compensate for this circumstance, various
precautions must be taken. These precautions include the following: reduce speed,
limit loads, ensure sufficient space at the bottom of the slope, etc.
The braking distance of a vehicle (which is used both for transporting loads and as a
towing vehicle) depends on many factors, including traffic in the form of other vehicles
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 vehicle must be adjusted accordingly.
Gangways and obstacles: Permanent gangways, travel ways or passages, floors
and ramps 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/or attachments and the space required for turning and maneuvering must
be clearly marked.
