Gas detection across paint, weld, engine test and battery assembly

Paint, weld, engine test and battery assembly produce four different gas problems; the design uses one alarm strategy across all of them.

An automotive plant carries a sequence of hazards along the line, one after another. The paint shop holds solvent vapour and the highest fire load. Welding releases fumes including hydrogen fluoride from flux. Engine test cells carry carbon monoxide. Battery assembly adds electrolyte vapour and, on the thermal-runaway path, hydrogen.

Because the processes sit close together, the alarm strategy has to be plant-wide rather than per-cell. A VOC alarm in the oven should stop the line before an operator opens a panel, and that logic lives in the controller, not in four separate instruments.

The battery line is the newest requirement and the one most plants are least prepared for. Off-gassing from a failing cell appears long before visible smoke, which is why hydrogen and electrolyte vapour channels are being added to lines designed before anyone thought about it.

Typical configuration

Paint shop	VOC and %LEL at ovens, flash-off zones and solvent stores
Weld shop	Fixed fume monitoring plus portable checks at manual stations
Engine test	CO and NOx at cell exhaust and around the dyno
Battery line	Hydrogen and electrolyte vapour at formation and aging racks
