 So today I'm going to talk to you about personal protective equipments also referred to as PPE and these are the equipments that are being used in a lab to eliminate the hazard that is in the workplace. So the first thing is when you're working in a lab you always wear a lab coat to protect your arms and you always wear long pants and closed toe shoes. Gloves are the most common PPE. You have to pay attention that gloves come in different sizes. You always choose a right size glove. If you want to work in more sterile environment you also can use the shoe covers and hats to cover your hair and depending on what you're doing during the day in the lab you might need to protect your face with a mask or a face shield usually when you're working with liquid nitrogen you want to protect your face and we have different types of gloves that when you're working with liquid nitrogen or dried ice you're putting these on to protect your arms and hands from burning and there are different types of goggles that you can use when you're doing cell culture or you're working with liquid nitrogen to protect your eyes from splashes.
