What should you do with long hair while working in the laboratory?

Securing or tying back long hair while working in the laboratory is crucial for safety. Loose hair can easily come into contact with chemicals, glassware, or flames, posing significant risks for accidents or injuries. By tying hair back, you reduce the chance of it interfering with your work or getting caught in equipment, which can lead to entanglement or spills. Additionally, having hair secured helps to maintain a clear and safe working environment, allowing you to focus on your experiments without distraction or risk. This practice is an integral part of personal protective measures in maintaining a safe laboratory space.
