It is not unless you have a deathwish - helium is used because it has a lower density than air.
Added:
The Hindenburg zeppelin disaster was mainly caused by the US ban on helium use in balloons.

Hydrogen gas was used in air balloons because it is much less dense than air and therefore rises, taking the balloon with it. it is unfortunately also very explosive so not used often anymore.
hydrogen
Hydrogen is not used to inflate hot air balloons. Just regular air is used which is then heated to make the balloon more buoyant as hot air weighs less than cold air. Hence the name hot air balloons.
Two of the gases that are used to fly balloons are Hydrogen and Helium. Helium is the preferred gas because Hydrogen is very explosive. The Hindenburg disaster was caused by the ignition of the Hydrogen gas that filled it.
Hydrogen gas is highly flammable and can form explosive mixtures with air, making it a significant safety risk in hot air balloons. If there is a leak or ignition source, hydrogen can ignite easily, leading to catastrophic fires or explosions. Additionally, hydrogen is odorless and colorless, making it difficult to detect leaks. These factors make it much safer to use helium, which is non-flammable, as a lifting gas in hot air balloons.
Hydrogen, until the Hindenburg,then everyone realized that "Hey, Hydrogen isn't that safe to use!"Hot air balloons, you mean?? Just air that is hot.Actual hand balloons and such? Helium or again, just air. Helium floats better because it is lighter than the surrounding air around it. Helium and air are still used in both.
Helium is the most used gas for balloons; sometimes hot air and rarely hydrogen.

Helium - it's less reactive.
Helium gas is commonly used to fill party balloons because it is lighter than air, making the balloons float.
Helium is used in blimps and balloons. It is the second lightest element to hydrogen, which is not used because it is highly flammable.
Helium is a gas used to inflate lighter than air balloons.

hydrogen, helium, hot air
Hydrogen gas makes the ballon lighter than air therefore it drifts upwards
Hot air balloons are typically filled with heated air, which is lighter than the surrounding air and provides lift. Some balloons may also use helium or hydrogen gas for buoyancy, but hot air is the most commonly used lifting gas for traditional hot air balloons.
