CHAIN GUARDS
Guards cover several points on circular collectors to prevent personal
injury from moving parts. If guards must be removed during
maintenance procedures, use caution when operating equipment and
replace guards when maintenance has been completed.
OPERATING ENVIRONMENT
Circular collectors are usually exposed to the elements. The bridge
and other access points may become slippery when wet or icy.
Handrails and other safeguards must be in place when working on the
equipment. Use care when access is necessary. Do not work outside
of the bridge handrails. Wipe up grease and oil spills.
The access area for drive maintenance is below the bridge deck
level. The difference in level will depend on the bridge design. A
falling hazard exists. Use caution when in or near the access area.
VENTILATION
Noxious fumes can be generated by septic sewage. Provide forced
ventilation and exhaust facilities when workmen are in a drained tank.
