How does the Walking-Working Surfaces rule apply to service vans?

29 CFR 1910 Subpart D expects you to maintain safe access into vehicles, secure ladders, and provide fall protection when technicians climb on roofs or racks. Document inspections for steps, grab handles, and tie-off points, then reference them inside your fleet JHAs. Update the log whenever accessories change and link the findings to PPE assignments, MEWP training, and near-miss reports so supervisors can verify corrections before vans leave the yard. Treat the van as a mobile jobsite and audit it monthly.
