The present Patent of invention "HELICAL RAMP LIFE-PRESERVER" refers to a model
of helical ramp, aimed for collective use, for immediate rescue of lives subjected
to a probable fire, to be used in buildings of any height, or in places that cannot
be reached by the devices currently in use, such as "Magirus" stairs, or even in
those where these devices can reach, but a probable delay to help would put in
risk people's life in an eventual emergency state.
