A DOT investigator wants paper you can put in their hand. A hazmat security plan if you haul bulk propane. Training records. Cylinder files. The papers that ride with the load. Some of that is a book we write. Some of it is records only you keep.
We do not do the audit, the inspection, or the training. The split below is the same split already published on what an auditor asks a propane dealer for, narrowed to the DOT investigator rows.
Which of those is a book we write?
The DOT hazmat security plan. We write it from a fixed template to the operation you describe on the intake form. Print-ready. Built within a week of your completed form.
See the DOT Hazmat Security Plan for Propane and whether you need one.
What stays in your file?
Annual review dates and 49 CFR 172.704 training completions stay in your file. We do not train the crew or keep the sign-in sheets. Cylinder files, driver files, truck files, and the papers that ride with the load stay yours.
How is this different from an insurance audit?
A loss-control representative and a state inspector also want written procedures and an SDS binder. The auditor checklist on this site lists those under the state inspector, AHJ, OSHA, and loss-control rows.
See what an auditor asks a propane dealer for for the full split. The written how-we-run book is the Policies and Procedures manual.
Next step: call 610-228-0887 and ask for the manuals intake form, or ask for redacted sample pages.
