Work environment

Danger area: A "danger area" is the area within which persons are endangered by
the traveling or lifting movements of the industrial truck or its load lifting devices (e.g.
fork or attachments), or by the loads being transported. This also includes the area
within reach of falling loads or falling / lowering truck attachments.
Qw W
Unauthorized persons must be required to leave the danger area. The driver
must give a warning signal whenever a situation presenting danger to
persons might develop. The industrial truck must immediately be brought to
a standstill if persons, although asked, do not leave the danger area.
The employer is responsible for rating any atmosphere or any area hazard under
ANSI/NFPA 505 and providing appropriate operator training on the subject.
Industrial trucks operated in danger areas and batteries used in such areas must be
approved and match the requirements of ANSI/NFPA 505.
Industrial trucks and application areas must be marked required by ANSI/NFPA 505.
Stopping distance: The stopping distance of an industrial truck, depends on many
factors, including other traffic and pedestrians, the amount of free space available,
the ground construction and the stability of the load(s).
Caution should be exercised with changed environments. Changes in weather, sur-
face conditions, or applications may effect the truck's stopping distance; speeds
loads, brake settings, and/or operation should be adjusted accordingly.
Aisles and obstacles: Permanent aisles, roadways or passageways and floors must
be appropriately dedicated or marked as required by ANSI Z535.2.
Restricted areas of truck operation require identification and/or marking.
In nonrestricted areas, the floor space boundary required for the truck and its load
and/or train shall be clearly marked, including the clearance necessary for turns and
maneuver.
Doors which open automatically and blind corners shall have suitable audible and/or
visual alarms to anticipate the approach of the truck and to allow for door actuation.
Passive devices such as mirrors are recommended also.
A minimum clearance of 1.5 ft (450mm) should be maintained between obstructions
and trucks (including loads). All other areas having reduced clearance shall be des-
ignated as restricted areas and be clearly marked by signs, stripes, lights, or other
designations.
– Automatic truck guide paths should not be routed through doorways frequented by
personnel unless the opening is wide enough for personnel to remain outside the
guide path clearance aisle. Also, opening and closure of powered or nonpowered
doors shall be accomplished in a manner that alerts or restricts personnel near the
doorway.
– In order to minimize the possibility of blocking the complete closing of a fire door,
the truck will respond to a signal such as an input from a limit switch and/or heat
sensor and stop prior to the fire door.
– System planning and design should not have a normal stop location where a truck
or its load would block a fire door closure.
