Entrance Tunnel
The doorway tunnel permits ingress and egress from the snow cave and can also be excavated first as a way to start development. Instruments ought to at all times be used for effectivity and security (see Frostbite, under).
The doorway tunnel ought to solely be as massive as essential to allow motion out and in, as a way to present higher insulation, and if doable, ought to be located in order that prevailing winds don’t come blasting into the inside of the snow cave.
If wanted, protecting baffles may be constructed across the entrance to offer higher safety towards wind.

As soon as extra, this isn’t a serious hazard as long as air flow is maintained, however this incidence will show lethal if the doorway tunnel and vent holes are closed up by snowfall when the occupants are sleeping.
Many victims of carbon monoxide succumb to its results whereas they’re asleep, so if there’s any doubt that this may increasingly happen go away somebody on watch and sleep in shifts for security.
