You go toward it. We make sure you can see it.
A hazmat call is a chain of decisions made in minutes, on a placard, a wind sock and a phone that keeps ringing. CERES is built with the people who make those decisions, so that the zone, the crew and the neighborhood are in front of them while there is still time to act. It runs in any browser on the apparatus laptop, the tablet and the phone, with nothing to install.
- The zone on the map before the first unit arrives, with the people inside it counted
- Every crew member on the board, every PAR answered, every minute logged without a clipboard
- The same picture on the truck, in the command post and at the plant gate, and a record the review can trust
Six moments of a call
Written from the responder's side. In each one, what CERES does comes second.
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.
Search by UN number, placard, name or the patient's symptoms. The ERG 2024 isolation and protective-action distances appear on the map, turned to the live wind, before the first apparatus stops. The Chemical Profile puts NIOSH, CAMEO and DOT data on one page, with the source on every line.
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.
ALOHA and the Pro models draw up to four levels of concern with the census population inside each. Threat at a point gives the indoor and outdoor dose over the first hour for that school, so the call is a number, not a feeling. Wind-confidence lines show where the plume goes if the wind backs or veers.
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.
Suit breakthrough by chemical (ASTM F739), the respirator class and SCBA time (OSHA 1910.134), APR canister life, PID and LEL correction factors with the Dräger CatEx LEL tables and 604 detector tubes, heat stress and stay time. Incident Weather read as a size-up: approach sector, stability, the next wind shift, lightning and heat for the crews.
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 Command Board puts crews on assignments by drag and drop, with one-tap PAR, air and work-cycle timers, MAYDAY and an automatic ICS 214 log, and keeps working without a connection. My Status from the phone, the team status board, a roster joined by QR code, and location shared only while responding.
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.
Call-down notification by email and SMS with the plume link, from templates, with a delivery log, and a public alert drafted from the zones as CAP 1.2. Share links that partners open without an account, and incident chat and video calls with them. A plant's detectors and met stations feed the same map, and a sensor-driven plume follows the readings as they report.
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.
PDF and Word reports with the map, zones and population; ten FEMA ICS forms, from the 201 briefing to the 214 activity log and the 233 action tracker; the incident record with tasks, log and costs. Story missions on a private exercise incident with the real tools, guided to learn and tested to qualify; Basics lessons on the tools and models, and incident-command lessons on taking command and accountability; a practice mode in most tool tours.

To the people who go toward it
CERES is built with fire departments, hazmat teams and plant fire brigades across the Americas, Europe, Asia and Australia, and shaped by what they asked for on scene. The measure of it was never the feature list. It is whether the zone was right, whether the crew came out, and whether the report told the truth. That part is your work, and it is the hardest work there is. Ours is to make sure nothing in the software stands between you and it.
Thank you for going toward it. Vlahi Systems
