Think of how many intricate things you do with your hands just to wire a switch. How well do you protect your hands?
Gloves are the standard PPE for hand protection. However, you must use the specific type of gloves that fits the situation. For example:
For electrical protection, wear gloves suitable to the energy levels involved. Test prior to use with the correct method (don't blow into them).
If you're using solvents, adhesives, or other chemicals, check the container label or Material Safety Data Sheet (MSDS) to find out which gloves to use.
Wear work gloves in situations where mechanical injury is possible. A slip with a saw can be a nonevent, or it can send you to the emergency room.
