Face masks are one tool utilized for preventing the spread of disease. They may also be called dental, isolation, laser, medical, procedure, or surgical masks. Face masks are loose-fitting masks that cover the nose and mouth, and have ear loops or ties or bands at the back of the head. There are many different brands and they come in different colors. It is important to use a face mask approved by the FDA. http://www.lioncare.net/medical-protection/face-masks/

Circuit breakers can be used as an alternative to fuses, but have significantly different characteristics. This is a cylindrical fuse. When the circuit fails or is abnormal, the current continues to rise, and the increased current may damage some important components in the circuit, or may burn the circuit or even cause a fire. If the fuse is correctly placed in the circuit, the fuse will cut off the current by itself when the current abnormally rises to a certain height and heat, thus protecting the safe operation of the circuit. http://www.wzcfdq.com/cylindrical-fuses/cylindrical-fuse/
