Yes Helium is safer than Oxygen, in that it does not feed combustion the way Oxygen does. In fact, a high concentration of Helium will extinguish a fire.
BUT …
In a closed area, you can suffocate if the concentration of Helium in the air gets too high.

Why is helium gas safer than hydrogen gas?
Because hydrogen is reactive and combines with oxygen, while helium is inert.
Helium safer than hydrogen?
Yes, because helium doesn't react, burn or explode.
Is oxygen lighter than helium?
no. If it was, we would have oxygen balloons instead of helium balloons.
How do you separate oxygen and helium gases?
They have different condensation points. Oxygen will turn into a liquid at a higher temperature than helium.
How does density of helium compare to density of oxygen and nitrogen?
Helium is lighter (less dense) than oxygen & nitrogen.
Why is helium used to fill balloons instead of oxygen or hydrogen?
Helium will not burn. Hydrogen burns in air to form H2O (water) Thus in circumstances where a lite gas is required (e.g. in a balloon) it is safer to use Helium. see http://www.unmuseum.org/hindenburg.htm
Is helium lighter or heavier than hydrogen?
Heavier but safer. Look what happened to the Hindenburg:(
Why can helium escape the earth's atmosphere?
Helium is lighter than oxygen and can escape the ozone.
Is hydrogen more dangerous than oxygen Why?
Hydrogen is dangerous than Helium because Hydrogen is a stronger gas than Helium.
Why is helium used in airships rather than oxygen?
Helium is a lighter gas than oxygen, ever seen balloons filled with helium? They rise upwards with heat due to a lesser amount of particles. If we used oxygen, the airships wouldn't get off the ground!
Is hydrogen or helium safer to use?
Generally speaking, helium is safer, as it is an inert gas, but Hydrogen is cheaper to make and is lighter.
How much faster does helium diffuse than oxygen?
Not much faster, but it does diffuse faster than helium because it is lighter.
