CAM-328

Cutting sparks next to the drums, with no fire watch

Early afternoon. A kneeling operator is cutting a pipe and throwing a jet of sparks onto the ground. A few metres to his left stands a row of drums and a large tote. Right in front of him, on the same slab, an unsecured red gas cylinder is standing upright. The wheeled extinguisher is on the far side of the walkway. There is no spark screen and nobody keeping watch.

The figures on this screen are an example from the illustration, not any client's measurement.

The rule

You decide once. IRIS applies it always.

cutting or welding sparks appear and no screen and no fire watch are in view

Then

alert the holder of the hot work permit
save the video from the first spark
record in the report how many drums and cylinders were in the frame

The instruction that set it up«Tell me if anyone cuts or welds here without a screen, without a fire watch, or with drums less than ten metres away.»

What changes

What changes for whoever answers for the plant

Hot work goes fine a thousand times and badly once. What separates the thousand from the one are the screen, the fire watch and the distance to product. The camera sees all three: it sees the sparks, counts the drums nearby and sees that nobody is watching. The alert goes out while the tool is still running, with video from the first spark.

What people usually ask

Does IRIS detect flammable gases?

No. A transparent gas does not show up in an image: a dedicated sensor detects it. A camera sees sparks, smoke, flame, drums and cylinders. That is a lot, but it is not a gas detector. Both are needed and they work side by side.

Can IRIS stop the job?

No. IRIS cuts no power and stops no machine. It warns while the job is happening and hands over the video with the time. Stop or carry on is decided by the permit holder, who knows the rest of the context.

Who decides what counts as a poorly protected job?

The plant does. IRIS does not write the rules: the plant states the distance to respect, whether a screen is required and whether a fire watch is mandatory. IRIS looks at whether that holds inside the frame and warns when it does not. Changing the rule means changing a sentence, not reprogramming anything.
