In an official safety briefing for an underground geothermal tunnel complex, the director announces: 'Under no circumstances is any technician authorized to enter Sector 4 without a verified dual-sensor atmospheric monitor, even if personal rebreathers are fully charged. While solo entry into Sectors 1 and 2 is permitted under active green-status ventilation, Sector 4 remains strictly under a mandatory two-person buddy protocol at all times, with motorized transport prohibited across all active drill corridors until full atmospheric clearance is logged.'
Based on this recorded safety announcement, a certified technician is permitted to conduct a solo inspection in Sector 4 as long as their personal rebreather is fully charged and the ventilation status is green.
