Parts of loads, machines, material or construction facilities permanently or temporar-
ily projecting into the normal operating area must be protected, clearly and visibly
marked or clearly visible.
Illumination of operating areas: Operating areas must be sufficiently illuminated as
per ANSI/IES RP7 see also, 29 CFR 1910.178 (h) regarding auxiliary directional light-
ing.
The user is responsible for equipping an industrial truck with working lights if the op-
erating conditions require so.
Sound: Powered industrial trucks may increase the working environment sound lev-
el. The customer/employer is responsible for noise assessment of the workplace and
consideration of and meeting the operator's need for ear protection.
Dock plates: Dock plates (loading aisles) must not be driven on.
Trucks with/without trailers and railroad cars: It is forbidden to use the industrial
truck in trucks, on trailers or railroad cars. In addition, railroad cars or trailers must not
be moved with a powered industrial truck unless it has been specially designed and
equipped for this purpose.
Floors and floor conditions: Areas of use for industrial trucks shall be smooth and
level, free of gaps, floor drains, etc.
The floor shall be maintained to keep them free of debris and liquids which hinder safe
operation of the truck.
Ramps and inclines in the area of truck use are forbidden.
Travel surface: The surface over which the truck system operates shall be main-
tained to ensure that the traction required for travel, steering, and braking perform-
ance can be met under reasonably anticipated environmental conditions.
Truck identification plate capacities and ratings are based on level, dry surfaces hav-
ing a minimum coefficient of friction with the driven and brake wheel of 0.6. Surface
conditions which deviate from this standard may adversely affect truck safety and re-
quire appropriate truck derating.
Physical environment: The physical environment, including temperature, humidity,
ambient weather, air quality (e.g. explosive, particulates, and/or gaseous constitu-
ents) shall be a part of the truck design criteria. Changes in the environment shall be
evaluated to verify there is no adverse effect on the truck's safety systems.
Radiated emissions: Many types of devices may emit energy, such as electromag-
netic, electrostatic, or optical, that could affect the operation of the vehicle system.
Likewise, vehicle systems may emit energy that could affect other systems and/or
personnel.
Users should seek guidance from the truck manufacturer if interference is suspected.
The conditions acceptable for the truck system installation shall be defined by user
and truck manufacturer agreement.
