Using a hot plate to heat an unknown liquid in a glass flask could be dangerous if protective/safety equipment aren’t worn. The unknown liquid may be a corrosive chemical which could cause burns when it gets in contact with any part of the body. It s therefore advisable to use googles to prevent the chemicals from splashing into the eyes. Safety gloves and long sleeve shirt should be worn to prevent heat and chemical burns. A shoe covering the whole part of the feet should also be worn as accidents such as the falling to the ground of the heated liquid may occur in the laboratory. This will help protect the feet from contact with the unknown liquid. Nose masks should also be put on to prevent inhalation of toxic chemicals into the body.
