What is the maximum amount of dry ice allowed to be shipped on Envoy aircraft, excluding dry ice for catering purposes?

The maximum amount of dry ice allowed to be shipped on Envoy aircraft, excluding dry ice for catering purposes, is indeed 70 lbs total. This limit is in place because dry ice, as a solid form of carbon dioxide, can release gas in enclosed spaces and potentially pose a suffocation hazard or pressure build-up in containers. The established guidelines allow this quantity to balance safety with the need for transporting items that require refrigeration.

Understanding the rationale behind the 70 lbs limit involves recognizing that this amount has been deemed safe for passenger and crew health while still accommodating sufficient dry ice for diverse logistical applications. Additionally, any shipments must be properly marked and packaged to comply with regulations that ensure safety throughout the flight.
