CAM-435

The liquid has left the containment and is running across the concrete

Midday on the concrete apron. The liquid waste tank, green and lying on its legs, has a dark stain at its foot that has already crossed the edge of the containment and is running down the ground toward the lane the trucks come in by. Two workers in hard hats and safety vests are standing right at the edge of the stain. IRIS sees a liquid spreading outside the area meant to hold it, and still growing.

The rule

You decide once. IRIS applies it always.

a liquid appears outside the containment area and the stain keeps growing

Then

alert the plant manager and the environmental officer with the camera and the time
save the video from before the first stain appeared
log the exact time and the starting point in the report for the environmental record

The instruction that set it up«Tell me if a pool appears outside the tank containment and keeps growing.»

What changes

What changes for whoever answers for the plant

A spill that gets past the containment stops being the plant’s own problem: it reaches the drain, and from the drain the sewer. That’s a file with the regulator. Seeing it after eleven minutes instead of at the end of the shift changes who cleans it and what it costs. The camera doesn’t say which liquid it is — the tank label or a lab test says that — but it gives the exact time, the video and the point where it started.

What people usually ask

Does IRIS know which liquid has spilled?

No. It sees a dark stain leaving the containment and growing, and that’s what it reports. What’s inside is told by the tank label, the packing slip or a lab test: a camera doesn’t confirm a chemical. What IRIS adds is the exact time, the point where it started and the video, which is exactly what you need to react fast and to write the report afterward.

Does it mistake rain for a spill?

No, not if the rule is written properly. A whole wet apron isn’t a spill; what raises the alert is a stain that starts at one point, crosses the edge of the containment and keeps growing when it’s no longer raining. That distinction is the plant’s call, not ours: where the camera looks, how much the stain has to grow and when it becomes an alert is written by the people who know the site.

Does it close the valve or stop the transfer?

No. IRIS doesn’t act on anything: it alerts a person and shows them the video. Stopping a transfer pump, moving the truck off the apron or calling the emergency service are decisions the shift supervisor makes, with the information in front of them. The camera works alongside the plant’s systems; it doesn’t replace them and it doesn’t give them orders.
