What is a key aspect of maintaining safety when using scissors?

Maintaining safety when using scissors involves various practices, and one key aspect is keeping the scissors closed when not in use. This is important because an open scissor presents a potential hazard to both the user and those nearby. When scissors are left open, the blades can inadvertently cause cuts or injuries if they come into contact with skin or other surfaces. Keeping scissors closed minimizes the risk of accidental injuries and ensures they remain safely stored or handled.

In contrast, cutting quickly can lead to accidents or mistakes, and passing scissors blade-first increases the risk for injury to others. Lastly, the necessity of using left-handed scissors is applicable only to those who are left-handed and does not address safety concerns universally. Thus, the practice of closing scissors not in use is a fundamental safety measure critical in a barbershop environment.
