Built with the people who go toward it.

One system for the whole chemical emergency, from the first call to the review.

The hazmat officer who has to say how far back people need to be. The incident commander who has to know where every crew is. The control-room operator whose detectors just alarmed. CERES is the complete incident management system they work with: identify the chemical, draw the zone with the people inside it, run the board, warn the neighbors and keep the record, on the truck, in the command post and in the control room.

Multi-platform connectivity, one interface: CERES on a monitor, a tablet and a phone, connected to The Weather Company, met stations, Gastronics fixed sensors, GPS devices and area and personal monitors from Industrial Scientific, Honeywell RAE, Dräger, Blackline Safety and AccuSense — Live weather, met stations, fixed sensors, GPS devices and portable gas detectors feed one picture on the desktop, the tablet and the phone.

The CERES Command Board: incident command, the hazmat branch and the responsible party on assignments, with the elapsed time and the PAR and MAYDAY buttons — The Command Board: drag crews onto assignments, run a PAR in one tap, watch the air timers and call a MAYDAY, while the ICS 214 activity log writes itself.

A chlorine plume in CERES with four colored levels of concern downwind, the threat-zone panel and the scenario panel — A chlorine release driven by a single detector reading: four levels of concern with the people inside each, and where the plume goes if the wind shifts.

A hydrogen sulfide footprint from a gas-pipe release, run with SCICHEM over an industrial area, with the detector readings on the map, the footprint time slider, and the people counted outside and sheltered — SCICHEM over an industrial area: the footprint replayed on a time slider, the detector readings on the map, and who is outdoors and who is sheltered.

A sensor-driven plume across an industrial site drawn from two detector readings, beside a Blackline G7 EXO area monitor — A sensor-driven plume: gas detector readings set the release rate, and the plume updates as new readings arrive.

The job, in six moments

Six moments of a chemical emergency, written from the responder's side. What CERES does in each comes second, on the product sheets.

The call comes in
A leaking tank car, a placard read from a hundred meters, a wind you are guessing from the smoke. The first question is what it is and how far back people need to be, and the honest answer at this moment is usually a guess.
The first decision
Shelter in place or evacuate. A school downwind, a hospital, a care home. Someone will ask you to justify it later. Right now you have to make it.
Someone has to go in
The entry team suits up on your word. What the suit stops, how long the air lasts at this work rate, what the meter is really reading, how hot it is inside the suit: those are your responsibility before they are anyone else's.
Everyone accounted for
Crews move, assignments change, the radio is busy and the tactical worksheet is a wet whiteboard. The one thing you cannot lose is where your people are.
The neighbors, the partners, the plant
Mutual aid arrives with its own map. The plant has readings you cannot see. Dispatch, the LEPC and the county want the same picture, now, and again by email.
After, and between calls
The report is due, the review is coming, and the next call will not look like this one. The team that does well on it is the team that practiced.

How CERES answers each one for a hazmat team And at a plant

Built with responders

We build CERES with the fire departments, hazmat teams and plant emergency responders who use it. What they ask for on a call, in a drill or in an after-action review is what goes into the next release.

Thank you for going toward it.

Written from your sideEvery screen starts from the decision you have to make. Every tool names the standard behind its numbers and every model its published basis, so you can stand behind the call.
Free for the responderOne responder can use CERES at no cost: the ERG, the ALOHA models, the map and most of the tools.
Practice without a page-outStory missions and lessons run on a private exercise incident with the real tools, so training never pages anyone.

One system for the whole incident

CERES follows an incident the way you work it: before the call, on the call and after it. Open an incident, and every model run, detector reading, assignment and decision is kept in its record.

Prepare

Before the call
- Tier II, RMP, Seveso and E2 facilities on your map, with the worst case already modeled for every Tier II or RMP chemical
- Predefined scenarios and vulnerability zones for the hazards in your district or around your plant
- Rosters that responders join with a QR code, teams, contacts and your agency's equipment, all set up before anyone is paged
Respond

On the call
- The material identified by name, UN number, placard or symptoms, with the ERG 2024 distances turned to the live wind
- Plume, fire and explosion zones with the people inside each, and where the plume goes if the wind shifts
- The Command Board for assignments, one-tap PAR, air and work-cycle timers and MAYDAY, even offline
- Call-down notification by email and SMS, incident chat, and share links partners open without an account
Analyze

After the call
- The incident record, with its tasks, activity log and costs, and the ICS 202, 203, 204, 208 and 214 forms filled in from it, in Word or PDF
- Reports with the map, the zones and the population; KML/KMZ, Shapefile and CAP exports
- Detector history, and the footprint replayed on the time slider for the after-action review

The Tools and Calculators workspace with the identify and predict groups shown as cards — 80 tools in nine groups that follow the incident, from identification to reference. Each one names the standard behind its numbers. Browse the catalog

The Incident Notification tool with an exercise ammonia-release message: notification type, priority, location, summary and the point of contact — Incident Notification: initial, update and final notices to your call-down list, from templates, with a delivery log for every recipient.

Plume modeling that keeps up with the wind

A straight-line plume assumes a steady wind over flat ground. CERES also models what happens when the wind shifts or dies, when the ground is not flat, when a fire makes smoke, and when your own detectors say otherwise.

A hydrogen sulfide plume on a harbor calculated from one detector reading, with heavy-gas zones, the downwind time cone and the wind-confidence lines — One detector reading at a harbor: the release rate calculated from the sensor, heavy-gas zones, the time cone, and lines showing where the plume goes if the wind shifts.

Wind shifts and calm air SCICHEM: Instead of a straight line, SCICHEM puffs follow the live and forecast wind through shifts, calm and light winds, for runs of up to eight hours. Every dispersion run also shows where the zone moves if the wind backs or veers.
Terrain, buildings and wind shear SCICHEM: Three-dimensional dispersion over hills and valleys and around large buildings (set up for your site), with wind that changes with height, and a vertical cross-section of the plume at any angle.
Smoke and soot PRO: Fire smoke treated as a hazard in its own right: the rising soot cloud and SO₂ from a burning tank and, with SCICHEM, where the soot comes back down.
Driven by your detectors: Live readings set the release rate, and the plume updates as the detectors report, with the arrival time and indoor and outdoor exposure at every receptor. Locate source works backward to the likely origin.
The models you already trust: The ALOHA 5.4 models, run natively and checked run for run against ALOHA output, plus Pro models for fire, explosion, boilover, battery fires and radiological releases.
People in every zone: Up to four levels of concern with the census population inside each, the downwind time cone, and the dose at a school or muster point.

SCICHEM comes with Live Facility; sensor-driven plumes with HAZMAT Team and Live Facility; the Pro models with Vulnerability and Risk and above.

See every model and its published basis

Two kinds of response, one system

A fire department needs the hazard zone and its crews in view within minutes. A plant needs its own detectors to raise the alarm, and its neighbors warned first. CERES is built for both, and gives them the same picture when they meet at the gate.

Fire departments and hazmat teams

Fire and rescue services, hazmat teams, and city and county emergency management

From a placard read at a hundred meters to the final report and the next drill: identify the chemical, draw the ERG or ALOHA zone, protect the entry team, account for every crew member and warn the neighbors, from the truck laptop, the tablet or the phone.

Support and questions

What is CERES?

CERES is the complete incident management system for chemical emergencies, from the hazmat call to the plant alarm: identify the chemical, draw the hazard zone with the people inside it, run the command board, read your own detectors and weather, warn the neighbors and keep the incident record, in any browser and in the iOS and Android apps. Vlahi Systems builds it with the fire departments, hazmat teams and plants that use it.

How do I get help?

Email support@vlahi.com at any time with what happened and your site name; we reply by the next business day. Licensed teams and plants also get phone support during US Central business hours. Every tool in CERES has a how-to tour, and the help comes in five languages.

Is there a free version?

Yes. CERES Free is for one responder: the ALOHA direct, puddle, tank and gas-pipe sources, every ERG 2024 event type, the map, scenario history and the free tools. Create a free account.

How do teams and plants buy CERES?

Vulnerability and Risk, HAZMAT Team and Live Facility are licensed per site, and each includes the one before it. Write to sales@vlahi.com for a quote, a walkthrough with your own site, or a trial license.

Which version of ALOHA does CERES use?

CERES runs its own implementation of the US EPA and NOAA ALOHA 5.4 source, dispersion, heavy-gas and fire models, checked against ALOHA output, and adds Pro models for cases ALOHA does not cover. Sites that need the original ALOHA program can still run it. The hazard models sheet lists every model with its published basis.

Can we change products later?

Yes. Write to sales@vlahi.com and we will move your site to the product you need.

How is our data protected?

Sign-in uses email and password with optional two-factor authentication, or a Microsoft, Google or Apple account, and is protected against password guessing. Roles are set per site, and share links show only what you publish. Plants that need their own servers can run a private deployment.

I forgot my password.

Open the password reset page and enter your email address; the reset link arrives by email.

What does "Vlahi" mean?

"Vlahi" means "Romanians": it is the medieval name for the people of the lands between the Carpathians, the Danube and the Black Sea. We named Vlahi Systems after it because we are proud of that heritage.
