Ladders, platforms and walkways
are designed to comply with strict
OSHA regulations. Carbon steel
fabrication with a painted finish is
standard. Stainless steel or galvanized
finish is available upon request.
Mounting brackets and other structural
accommodations can be factory-fitted
to facilitate field installation. Interior
access ladders require a properly sized
access manway for safety clearance.
Standard or caged external access
ladders are designed for access to
the tank top, fill port, manways or
tank appurtenances. Handrails and
provisions for anchoring to a support
pad are also included.
Note: OSHA-compliant internal ladders measure 16" wide and external ladders measure 24" wide.
