Primary-source directory
Loading Dock Resources
A short directory of primary sources a facility manager can use to understand loading dock equipment, safety rules, Louisville permit offices, and detention research.
This index keeps official rules, standards catalogs, manufacturer documents, and research in one place without treating unlike sources as interchangeable. Start with the question in front of you, then read the limitation before relying on a document.
Orientation
How to use these loading dock safety references
A useful loading dock resource answers a narrow question. Louisville Metro pages explain its application, permit, fee, license, and inspection processes. Kentucky statutes and regulations address state-level licensing and adopted code material. OSHA pages provide federal rule text. Standards organizations define equipment categories and point to published standards. Manufacturer pages describe particular product families or manuals. None of those sources, by itself, decides the condition of a bay.
For proposed work, identify the property's issuing office first. A Louisville mailing address does not turn a general permit page into a decision for that opening, operator, control, or supporting structure. Ask the responsible office which application applies and what documentation it needs. The linked fee schedule is included as a current-reference destination, not reproduced here and not applied to a hypothetical job.
For equipment questions, record the manufacturer, model, and available manual from the installed door, leveler, restraint, or operator. A mechanical leveler manual should not be generalized to pit hydraulics, and commercial-door guidance should not be assumed to cover every rolling curtain, sectional panel, photo eye, bottom bar, or control mode. Use the source to sharpen the question for qualified personnel, not to create a repair procedure.
Working links
Primary-source directory for facility managers
The directory is ordered from local permits and code through licensing, safety standards, equipment guidance, and industry data. Each row says both what the source can answer and where its authority stops. Linked standards and manuals remain the publishers' material; this page does not reproduce them.

Interpretation
Rules, manuals, and research have different jobs
OSHA's dockboard and hazardous-energy pages are rule sources, not a clearance to keep a position in use and not instructions for servicing it. A facility's own safety program and appropriately qualified personnel govern the response to a failed leveler, uncertain restraint status, damaged door, or exposed mechanism. Do not use this directory to improvise spring, cable, electrical, hydraulic, lockout, or pit-entry work.
Industry standards and definitions help distinguish a dock leveler from a portable dockboard, or a sectional door from a rolling assembly. They do not establish that a particular installation complies. Editions can change, purchased standards are not reproduced here, and the listing or instructions for the installed equipment still matter.
The ATRI entry is national detention research. Its row preserves the publication and study years supplied by the source, while its limitation prevents a local inference: it is not Louisville data and does not attribute detention to broken dock doors. That distinction matters whenever research is used to frame an operational question.
