What is a safety requirement when using clippers?

Regularly oiling clipper blades is crucial for maintaining their functionality and safety during use. Oil reduces friction between the blades, which helps prevent overheating and ensures a clean, efficient cut. Neglecting this maintenance can lead to dull blades, increased risk of pulling hair, or even causing accidental cuts or injuries to the client. Additionally, well-oiled blades can prolong the life of the clippers, making them a more cost-effective tool in the long run.

The other options, while relevant to clipper use, do not focus on the same level of maintenance and safety when it comes to ensuring the tools function well during use. For instance, using only on dry hair or avoiding use on sensitive skin are practices that address client comfort and safety, but they do not directly relate to the operational safety and effectiveness of the clippers themselves. Maintaining a slow cutting pace can be important for precision, but it does not fundamentally address the mechanical care of the clippers. Therefore, regular oiling stands out as a specific safety requirement essential for the effective operation of clippers.
