Plant-wide response that never stops the line blind.

A manufacturing complex tied process-safety alarms, evacuation and shelter-in-place to one platform — hardened for high-noise, hazardous zones and OSHA / EHS compliance.

// The Operational Reality

On a loud floor, an alarm nobody hears is no alarm at all.

Across 2.4 million square feet of high-noise production, audible-only alarms didn't reach the floor. Worse, process-safety alarms weren't tied to evacuation — operators had to interpret a horn and decide what to do.

There was real confusion between shelter-in-place and evacuate, and OSHA / EHS accountability after an event was a manual headcount that nobody trusted.

Unheard alarmsAudible-only warning is lost on a high-noise production floor.
Alarms not tied to actionProcess-safety alarms didn't drive a defined evacuation.
Shelter vs evacuate confusionNo clear, automatic logic for which response to take.
Manual accountabilityPost-event headcounts were slow and unreliable for EHS.
// The HQE Solution

A unified system, engineered to fit.

HQE made the right response automatic — the correct zone evacuates, the rest shelters, and every worker is accounted for.

1
Reach

High-dB voice + strobe

Zoned high-output voice and strobe notification cuts through the loudest areas of the plant.

2
Automate

Alarm-to-action logic

Process-safety alarms drive a defined response automatically — no operator interpretation required.

3
Decide

Shelter vs evacuate

Zone logic evacuates the affected area while the rest of the plant shelters in place, clearly and simultaneously.

4
Account

RFID muster

RFID muster tracking delivers 100% worker accountability and an OSHA-ready audit log.

// Systems Deployed

The stack behind it.

Every deployment integrates the systems you already own, unified through HQE's proprietary ML/AI-powered ecosystem — all in one pane of glass.

// How We Deliver

From survey to sustained operations.

A disciplined, mission-grade delivery process — the same five phases on every HQE engagement.

01

Assess

RF / coverage survey, threat model & compliance gap analysis on-site.

02

Design

System design engineered to your existing infrastructure, facilities and mandates, regardless of the brands already installed.

03

Integrate

Bridge existing systems — alarms, access, C2 — into one pane of glass.

04

Deploy

Phased install, load-testing, live drills & operator certification.

05

Sustain

24/7 monitoring, supervised health & lifecycle support contract.

// The Outcome

Measurable mission impact.

6s

Alarm-to-evacuation

A process-safety trip drives the right zone's response in seconds.

100%

Muster accountability

Every worker accounted for via RFID at the muster point.

1

OSHA-ready audit log

Each event auto-documented for EHS and regulators.

When a process alarm trips, the right zone evacuates and the rest shelters in place — automatically — and we account for every worker.
