1.4.1 Guards and Guarding
Where necessary for the protection of personnel from hazards, all exposed moving
machinery parts that present a hazard to employees at work stations or operator’s
stations shall be mechanically or electrically guarded, or guarded by location or
position
Interfacing of Equipment
When two or more pieces of equipment are interfaced, special attention shall be
given to the interfaced area to ensure the presence of adequate guarding and safety
devices.
Guarding Exceptions
Wherever conditions requiring guarding under these standards, but such guarding
would render the conveyor unusable, prominent warning means such as signs or
warning lights shall be provided in the area or on the equipment in lieu of the
guarding.
Guarded by Location or Position
Remoteness from frequent presence of public or employed personnel shall constitute
guarding by location. Overhead conveyors, such as trolley equipment and hanger-
suspended tray conveyors, for which guarding would render the equipment unusable
or would be impractical, shall have prominent and legible warnings posted in the
area or on the equipment, and, where feasible, lines shall be painted on the floor
delineating the danger area.
When the equipment passes over a walkway, roadway, or work station, it is
considered guarded by location if all moving parts are at least 8 ft. (2.4 m) above the
floor or walking surface or are otherwise located so that the employee cannot
inadvertently come in contact with hazardous moving parts. Although overhead
conveyors may be guarded by location, spill guards, pan guards, or equivalent shall
be provided if the product may fall off the conveyor for any reason and endanger
personnel.
