Built for logistics-yard EHS managers and yard procurement leads; speaks the language a yard inspector opens against. Every signal Pactwell reasons across maps to a named OSHA 29 CFR 1910.178 operator and truck-operations citation, a 29 CFR 1910.146 permit-required confined-space entry, or a 29 CFR 1910.176 materials-handling rule — so the audit-ready PDF the platform writes at the moment of the breach is the same evidence the inspector opens.
Why Pactwell in a logistics yard
OSHA 29 CFR 1910.178 powered industrial trucks, 1910.146 PRCS, and 1910.176 materials-handling coverage are not aspirational — they are the standards your inspection opens against. Pactwell’s sensor + permit + CCTV correlator writes to those standards directly, so the evidence pack the morning of the walk is the same pack the platform wrote at the moment of the breach.
OSHA 29 CFR 1910.178 · Powered industrial trucks
Pactwell reasons across the certification roster on every operator badge, the daily inspection checklist the shift turn-over signs, and the proximity sensor at the truck itself. The forklift stops being a moving hazard and becomes the boundary of an evidence pack — every crossing, every near-miss, every alarm state written to the same log the inspection opens.
OSHA 29 CFR 1910.146 · PRCS · + 1910.176 · Materials-handling, general
Wheel-restraint interlocks, leveller engagement, king-pin landing verification, and the wheel-chock contact sensor — every trailer arrival is checked against the dock permit window the load planner registered. If a permit surface drops out of compliance in the same window, the correlator writes the evidence pack, not the morning after the trailer left.
Pedestrian–vehicular traffic management
Forklift–pedestrian proximity at aisle intersections, audible and visual alarms at reverse-corridor crossings, and spotter badge-in at every active loading face. Each one written against the permit window it operates inside, so the day the inspector reaches for his tablet, the record matches the bay the camera was pointed at.
Skeptical yard EHS managers, answered
The conversations we lose are the ones where the manager already has a CCTV stack and a gate reader, can prove the alarms get ignored, or has caught spotters leaving the post after the fact. The answers below are the ones we open with.
We already have CCTV and a gate reader.
CCTV gives you the frame after the fact. The gate reader gives you the badge crossing. Neither one tells you a forklift was inside the pedestrian-zone envelope at the same minute the pedestrian badge was in the same bay without a spotter. Pactwell reasons across them — we are not another camera or reader.
Forklifts are loud — proximity alarms get ignored.
A constant audible alarm gets tuned out. Pactwell times the audible output of the correlator to the inverse of approach speed (slower approach → longer warble), drives corridor LED lights at the crossing, and pushes a supervisor-dashboard flag while the alarm is still ringing — so the alarm is heard because it changes shape, not because it is louder.
Spotters leave the post for breaks and we have no record.
Spotter badge-in at the bay reader is timestamped against the active door-open window. When the spotter badge is absent beyond the threshold interval while the loading permit is still live, the correlator writes the absence to the audit trail in the same minute — not retroactively after a supervisor notices.
What gets watched in a yard
The matrix below names the surfaces the correlator is tuned to in a logistics yard — from aisle-intersection proximity to trailer landing without chocks. Each card pairs the input combination with the evidence puck Pactwell writes when the combination fires.
InputForklift proximity sensor + pedestrian-zone badge reader
Aisle-crossing evidence puck: timestamp, both badge IDs, distance envelope, and the CCTV frame at the lead-up.
InputSpotter badge-in reader + dock door contact sensor
Spotter-presence puck: badge-in timestamp window vs. door-open window vs. permit window, with the absence interval highlighted.
InputWheel-restraint contact sensor + leveller contact sensor + trailer-arrival reader
Dock-permit puck: landing sequence timestamped against the wheel restraint and leveller state sensor, with the trailer ID cross-referenced to the load-plan permit.
InputPIT envelope proximity sensor + pedestrian badge
PIT-zone puck: pedestrian badge crossing without a spotter-cleared permit for the aisle, with the CCTV frame at the crossing.
InputReverse motion sensor + pedestrian badge crossing + audible alarm state
Reverse-corridor puck: motion crossing with no audible alarm state in the same window — alarm muted or disabled — flagged at the supervisor dashboard.
InputKing-pin sensor + wheel-chock contact sensor + driver badge
Trailer-landing puck: trailer landed, king-pin engaged, wheel-chock contact "open" with no driver badge clearing in the audit window.
Inputs → outputs
The matrix below pairs the inputs Pactwell reasons across — forklift proximity sensors, pedestrian-zone badge readers, dock door contact sensors, the spotter certification roster, the wheel-restraint and leveller interlocks, and the CCTV feeds pointed at the loading face — with the yard signal each combination reasons over and the compliance output the audit-ready PDF references.
Yard signal Pactwell reasons across
Forklift proximity sensor fires inside the pedestrian-zone envelope while a pedestrian badge is in the same bay without a spotter badge crossing the same reader, with no stop-record from the operator in the preceding interval.
Compliance output
Yard signal Pactwell reasons across
Dock door contact open, loading permit active, spotter badge absent for at least the threshold interval while a forklift or pedestrian badge crosses the same reader.
Compliance output
Yard signal Pactwell reasons across
Wheel-restraint state sensor "unlocked" while the trailer is in the bay with the leveller extended and the loading permit active for that trailer ID.
Compliance output
Yard signal Pactwell reasons across
Trailer landed, king-pin sensor engaged, wheel-chock contact sensor "open" with no driver badge clearing the audit window, while the loading permit is registered for that trailer.
Compliance output
Yard signal Pactwell reasons across
Pedestrian badge crossing the PIT envelope without a spotter-cleared permit for the aisle, with no spotter badge at the aisle reader in the same window.
Compliance output
Yard signal Pactwell reasons across
Motion sensor firing in the corridor while a pedestrian badge crosses with no audible alarm state in the same window — alarm muted or disabled — and no supervisor overlay on the alarm output.
Compliance output
Compliance citations are written against the published OSHA standards — 29 CFR 1910.178 (Powered Industrial Trucks), 29 CFR 1910.146 (Permit-Required Confined Spaces), and 29 CFR 1910.176 (Materials Handling, General).

Run the correlator on the highest-risk bay
If you already have the forklift proximity sensors, the loading-bay spotter badge readers, the wheel-restraint interlocks, and the CCTV feeds at the dock face online, start free at /signup and run the same pilot the matrix above is written against — connect sensors, register permits, point Pactwell at the VMS, and watch a flagged incident arrive inside two weeks. If you’re still evaluating the shortlist, the door for that is open too.
