Breakdown
ZERO SPARK
Cold-Cut Mandate
Absolute prohibition on any heat-generating tool — grinders, torches, friction saws, or plasma cutters — within the work boundary. Only diamond wire, hydraulic shears, and nibbler technology approved for metal removal.
DIAMOND WIRE
Wire Saw System
Diamond wire saw operates via hydraulic drive with no electrical components within the cutting zone. Wire loop tension and feed rate calibrated to vessel wall thickness to prevent frictional heating above 40°C surface temperature.
LEL BOUNDARY
10-Meter Exclusion Zone
Four-point LEL monitoring grid established at 10-meter radius from cutting zone. Any reading above 5% LEL triggers immediate work stoppage, tool withdrawal, and ventilation assessment.
HAZWOPER
Emergency Standby
Level B PPE-equipped HAZWOPER responders on standby for the duration of all segmentation operations. Medical surveillance and decontamination station established at the exclusion zone perimeter.
