Problem:

Question: How long can a naked human survive at the surface of the Mars planet?

For instance, let's say a worker's base takes fire while he sleeps, and he has to run to the emergency building 200 meters away without any respiratory equipment, pressure suit, UV protections or anything.

Question: Maybe a human could survive for a rather long time, and apnea time is the real limiting factor?

Climate:

Temperature: 27 °C to ?50 °C (base is at a rather warm location, on Equator)
Pressure: 600 Pa (Earth: 101,000 Pa)

Please explain about " Is human can survive on Mars".
