Why is there glass around an incandescent bulb?

In order to keep oxygen away from a light bulb’s filament on Earth, some bulbs have most of the air removed, others are simply filled with an inert gas (one that does not burn or aid combustion). Thus on Earth the glass globe around the filament is necessary to keep the filament isolated from the oxygen in the air.

What happens if an incandescent light bulb breaks?

Instead, incandescent bulbs usually contain an inert gas, such as argon, to prevent the filament from corroding, and the gas is contained in a thin glass shell. The shell is fragile, and if it breaks, it produces thin shards of glass that easily penetrate skin and eye tissues and can even be inhaled.
