The glow stick contains two chemicals and a suitable dye (sensitizer, or fluorophor). The chemicals inside the plastic tube are a mixture of the dye and diphenyl oxalate. The chemical in the glass vial is hydrogen peroxide.
The chemicals in glowsticks are securely encased in the plastic tube and you will usually not come into contact with them at all. If your glowstick is punctured, though, it's possible that a small amount of these chemicals might leak. The chemicals are not poisonous, they're not radioactive, and they're not flammable.
