FullBox is the firefighter’s personal PPE locker — always up to date, always ready for review. Forget tracking down your gear records in binders, emails, or spreadsheets. FullBox gives every firefighter a simple digital locker: see what you’ve been issued, check inspection status, submit requests, and get notified when something needs your attention — all from your phone. Your Digital Locker Everything issued to you — Structural PPE, Wildland PPE, and SCBA — is organized in one place. Tap any item to see its full history: last inspection date and type, maintenance records, and current status. Inactive or retired gear is only a tap away, never lost. Inspections on the Go Perform weekly, monthly, annual, and post-repair inspections directly in the app for all equipment. Bulk inspections let you process multiple items in a single session. Every completed inspection is logged instantly and made available to your PPE manager without extra steps. 4 Clicks to Request Need new gear, a repair, or advanced cleaning? Submit the request in seconds and track its status. No paper forms, no emails, no follow-up guesswork. Stay Informed Receive push notifications for inspection due dates, overdue reviews, request status changes, and gear ready for pickup. Your PPE manager sets the schedule — FullBox keeps you informed so nothing slips through. Built with Fire Departments, for Fire Departments FullBox supports NFPA-informed PPE tracking and Cal/OSHA-aware recordkeeping. It works alongside your department’s existing policies and review schedules — not against them. Your records stay current, searchable, and ready for review at any time. The firefighter digital locker is just one piece — but it’s where accurate records start. FullBox is part of a complete department PPE system used by PPE managers, quartermasters, logistics teams, and command staff. Requires an active FullBox department account. Contact your PPE manager or visit fullbox.io to get started.
