Field safety sensors

The handset's own radios and sensors wired to the incident ledgers. A Bluetooth heart-rate strap, pulse oximeter or 4-gas monitor streams into a watchdog that compares every reading with confined-space and altitude thresholds at your sector elevation: strain rotates you to rehab, low SpO₂ sends a medic, a bad atmosphere fires the scene-wide ALL STOP and a hazmat escalation. Push-to-talk turns a spoken report into a timestamped, geotagged ICS-214 or triage line without taking a hand off the rope. A one-tap NFC scan audits a trauma pack, rope bag or pharmaceutical cooler and raises the resupply requisition when a seal is broken, a drug is expired or the cold chain failed. The dive-to-elevation lock keeps a recently surfaced Track 4 diver off hoists, aircraft and high HLZs until the surface interval has run. Safety aids — the safety officer, medical direction and the dive supervisor govern. Not medical advice.

Incident

1 · 4-gas & biometric watchdog

Thresholds: O₂ < 19.5 % or > 23.5 %, LEL ≥ 10 %, CO ≥ 35 ppm, H₂S ≥ 10 ppm → CRITICAL GAS EVAC · SpO₂ < 90 % (< 80 % above 2 500 m) → HYPOXIA · core ≥ 38.8 °C or HR ≥ 185 → REHAB.

2 · Push-to-talk voice → ICS-214 / triage

4 · Dive-to-elevation & flight decompression lock

Surface interval 12 h; 18 h after a dive deeper than 18 m, longer than 40 min, or repetitive — before any flight, hoist or elevation ≥ 600 m (DAN / US Navy flying-after-diving guidance, conservative). Crew-call acceptance and hoist vectoring consult the lock automatically.

Kit audits

Web Bluetooth: Heart Rate service 0x180D (HR measurement 0x2A37), Pulse Oximeter service 0x1822 (PLX continuous 0x2A5F, SpO₂ + pulse); 4-gas monitors expose vendor UUIDs — the console pairs any device advertising a 128-bit service and reads a 7-byte frame (O₂×10, LEL×10, CO, H₂S) from its first notifying characteristic, else type the display. Web Speech API for dictation (falls back to typing); Web NFC NDEF text record "KIT:callsign;CAT:category;SN:serial;EXP:YYYY-MM-DD". Readings and lines queue offline and replay. Not medical, engineering or diving-medicine advice.
