In which situation is it necessary to wear gloves?

Wearing gloves is essential when cleaning broken glass to protect your hands from cuts and injuries that can result from handling sharp edges. Broken glass poses a significant risk of lacerations, and gloves act as a barrier between your skin and the hazardous material, minimizing the chance of injury.

In contrast, while changing light bulbs and using power tools may involve some risks, the specific need for gloves is not as universally applicable as it is with broken glass. Light bulbs do not typically present sharp edges in the same way that broken glass does, and while using power tools may produce debris or cause vibrations that can be uncomfortable, gloves are not always required for general tool use. Sitting at a desk presents negligible hazards that would require gloves, making it an inappropriate situation for their use.
