Risks include toxic exposure (IDLH 300 ppm), flammability above 16% in air, brittle fracture during cold-tank warm-up (-33 °C inner shell), high-elevation cutting on 30 m double-wall geometry, and contaminated insulation handling.”","path":"/entities/hirva-anwesha-infratech-limited-q140234753#company-fact-content-native-digital-agencies-4656e704b871b63b-a-b5765e3da2fbc831a303","questionPaths":["/entities/hirva-anwesha-infratech-limited-q140234753#company-answer-content-native-digital-agencies-4656e704b871b63b-a-b5765e3da2fbc831a303"]},{"id":"content-native-digital-agencies-4656e704b871b63b-a-f46d3c80f0212c8c0fb9","label":"What is reverse jacking and why is it safer?","value":"“Reverse jacking lifts the shell with synchronised hydraulic jacks so each ring is cut at ground level instead of at 25–30 m height. It eliminates ~90% of working-at-height man-hours, removes the need for full external scaffolding (~600 MT material avoided), shortens the schedule by 35%, and gives much better vapour control during cutting.”","path":"/entities/hirva-anwesha-infratech-limited-q140234753#company-fact-content-native-digital-agencies-4656e704b871b63b-a-f46d3c80f0212c8c0fb9","questionPaths":["/entities/hirva-anwesha-infratech-limited-q140234753#company-answer-content-native-digital-agencies-4656e704b871b63b-a-f46d3c80f0212c8c0fb9"]},{"id":"content-native-digital-agencies-4656e704b871b63b-a-b7bdd5771d5aee367628","label":"Has HAIL completed an ammonia tank decommissioning?","value":"“Yes.
