In the first mile and the last mile, you need predictable cold, clean paperwork, and clear SOPs. Two numbers frame your risk: CO₂ 8‑hour TWA 5,000 ppm and IDLH 40,000 ppm. Stay within limits, size coolants smartly, and align with PI 954 when you use real dry ice. What is reusable dry ice and when is it better for −20 °C to −30 °C lanes?
