Why is it important to wear gloves and protective clothing during filling procedures?

Wearing gloves and protective clothing during filling procedures is crucial for safeguarding against physical hazards such as freeze burn and frostbite. Many filling processes involve handling materials at low temperatures or using cryogens, which can cause severe skin damage if they come into contact with bare skin. The protective gear acts as a barrier, ensuring that any exposure to these hazardous substances does not directly affect the skin, thereby preventing injuries such as frostbite.

While maintaining cleanliness is an important aspect of many laboratory and filling procedures, the primary focus in this context is on the physical protection that gloves and clothing offer against the specific risks associated with cold materials. It's worth noting that other options, such as avoiding allergic reactions or preventing electrical shocks, may not be as directly relevant to the specific hazards presented during the filling procedures being referenced.
