This example from the Tajima Motor Company, the Tsunami Floating Shelter SAFE+, aims to provide a last resort option for emergency workers who have left it too late to escape.
Claimed to be both unsinkable and immensely strong, the SAFE+ is available in two sizes – 20 or 10 person capacity, with the larger unit also able to cater for a wheelchair bound person. All passengers are provided with 4-point seat belts and protective seating (tie downs and belts are provided for the wheelchair occupant) and the pod also has full 180 degrees self-righting capability according to Tajima Motor Company. When the time comes to escape the Shelter, egress can be made from either the main door, which opens well above the waterline, or through a roof mounted hatch.
The size of the pod has been kept as compact as possible, with the larger 20 seat model weighing only 1300 kg (2866 lbs) and measuring 6.2 m long, 2.3 m wide and 2.3 m high (20.2 x 7.6 x 7.56 ft), so it's roughly the size of a large SUV. The smaller 10 seat model is almost half the size, at 3.4 x 2.0 x 2.1m. Such compact dimensions make the SAFE+ easily transportable by a flatbed truck or capable of being stored in a normal car parking space or on an evacuation tower.
