For the E175, what is the maximum dry ice load allowed in the forward cargo only?

The maximum dry ice load allowed in the forward cargo compartment of the E175 is 400 pounds. This limitation is established for safety reasons, as dry ice can create a significant amount of carbon dioxide gas as it sublimates. If the cargo area is overfilled beyond the specified limit, there may be inadequate ventilation, leading to an accumulation of carbon dioxide, which could pose a risk to both the crew and the passengers.

This weight limit ensures that there is a sufficient space for ventilation, mitigating the risk of asphyxiation. Aircraft manufacturers and regulatory bodies set such limitations based on testing and operational safety considerations, making it crucial for operators to adhere to the specified maximum loads to promote a safe flight environment.
