An emergency stop activates. The search begins.
- The exact stop point is unclear
- Teams rely on calls, radio messages or a physical search
- Response ownership and timings are difficult to prove
- Incident knowledge is scattered or lost
Safety Intelligence Platform
Patent PendingGB2514612.7
Know exactly which emergency stop was activated — without modifying the existing safety circuit.
CSS adds a read-only monitoring layer to existing emergency stops, then turns every activation into a located, owned and traceable incident.
Independent · Family-run · Lancashire-based
Monitoring layer, not the safety function. CSS does not control, reset or replace the emergency-stop safety system.

The operational difference
From “something stopped” to “we know exactly where”.
CSS removes the location gap that slows the first minutes of an emergency-stop response.
The exact stop is identified. The response starts.
- Site, area and monitored stop point are shown immediately
- The right people receive a clear alert
- Ownership, actions and timestamps stay visible
- Every event becomes evidence for improvement
One connected workflow
Detect → Locate → Respond → Record → Learn
A clear path from physical activation to operational intelligence—while the existing safety circuit remains untouched.
Simple by design
A monitoring layer around the safety function.
The sensor observes activation. The field unit carries the event securely into the CSS platform. The existing emergency-stop circuit continues to perform its safety function independently.
E-stop
The emergency stop continues to operate through the existing safety circuit. CSS sits outside that protective function and does not alter its control logic.
Real product workflow
One operational picture, from control room to responder.
The CSS dashboard gives teams a live operational view while the Android app carries the incident, response history and supporting evidence into the field.

Safety Intelligence Platform
Turn a stop signal into faster action and usable intelligence.
Locate the event. Mobilise the response. Measure the impact. Keep the evidence. Close the follow-up work.

Make the operational impact visible.
Build an evidence-based picture of what happens after an activation—so decisions are based on recorded events rather than recollection.

CSS is designed to reduce avoidable response delays. Measured pilot data will be used to establish and evidence customer-specific improvement.
Reports that make the case
Turn operational data into management evidence.
CSS brings response performance, physical downtime, estimated cost and corrective-action governance into clear reports for safety review, audit support and investment decisions.
CSS reports shown with demonstration data. Personal identifiers have been obscured. Financial values are operational estimates, not accounting entries or realised losses.
Assisted intelligence, human control
Help people understand the data—not hand decisions to a machine.
CSS is developing carefully bounded AI capabilities around the platform. The assistant supports people; it does not operate machinery, change the safety state or make autonomous safety decisions.

Contextual help inside the platform
Read-only guidance, incident summaries and diagnostic explanations help users understand what they are seeing and find the right workflow more quickly.
AI AnalyticsIn development
Surface patterns that deserve attention
The planned analytics layer is intended to highlight recurring activations, costly areas, response trends and follow-up priorities for human review.
AI boundary:advisory and read-only by design; outputs require human judgement and must not be treated as a substitute for competent safety assessment.
Engineering hardware shown · Production appearance may changeReal-world validation
Built for controlled pilots, not speculative promises.
CSS has functioning hardware, firmware, dashboard and mobile-app workflows. The next stage is controlled pilot deployment, repeatable small-batch preparation and measured feedback in real operating environments.
- Site review and an agreed, asset-specific scope
- Configured devices, dashboard and Android-app access
- Installation, functional checks and recorded test evidence
- Named users, support and agreed success measures
- End-of-pilot findings and a clear next-stage decision
Why Close Safety Systems
Practical engineering, joined to the whole incident workflow.
CSS is an independent, family-run Lancashire business. We are building the hardware and software as one traceable system, with a clear boundary between operational monitoring and the existing safety function.
