Conveyor guards

Persons often work near operating chain drives or conveyors. Guarding should be designed to prevent persons from coming in contact with the chain and sprockets during normal operation.

On long conveyor runs it may be necessary to construct bridges to provide access to the opposite side of the conveyor. Long runs of conveyors present particular guarding problems and an acceptable solution is by the provision of a trip wire along the whole length of the machine Figure 27.18) which must be placed close to the belt so that it is immediately available in an... 

Because of the injury potential of these conveyors, they should be guarded so that when in use there is no possible means of access to them Figure 27.23). Repairs and maintenance should only be undertaken when the drive motor is locked-off. 

Screw conveyors shall be guarded to prevent employee contact with turning flights. 

Where a conveyor passes over work areas, aisles, or thoroughfares, suitable guards shall be provided to protect employees required to work below the conveyors. 

All moving parts of conveyors must be effectively guarded. 

Screw conveyors, often used to move very viscous substances, must be provided with either fixed guards or covers to prevent accidental access. People should be prohibited from riding on belt conveyors and emergency trip wires or stop buttons must be fitted and operational at all times. 

Conveyors and machinery, including pulleys, guards, and other metallic components, must be bonded and grounded to prevent static discharges. Belts should be made of a conductive material, have a conductive coating, or have a grounded static collector just beyond the point at which the belt leaves the pulley. 

Scenario 4 A conveyor consists of several rollers that are four feet long and three inches in diameter that are covered by sheet metal guards. To properly clean these rollers, the equipment must be running. The guards are removed, and the rollers are sprayed using a water hose as an extended tool.

Screw conveyors must be completely covered except at loading and discharging points. At those points, guards must protect employees against contacting the moving screw the guards are movable, and they must be interlocked to prevent conveyor movement when not in place.
