Thermal Hazards 2:54-3:20 Another safety consideration is thermal radiation or heat. Devices inside a computer generate heat,in particular, the CPU and memory. Allow a system to cool down before you work on it because some components can get hot enough to cause a severe burn. Any device that has a heat sink or a heat spreader in it should tell you to let that device cool downbefore you touch it. These devices present a definite safety hazard. Physical Hazards 3:21-3:40 Your physical surroundings are another component of safety. Arrange the room in which you work to eliminate physical hazards. Use proper cable management and don't leave wires on the floor. Don't leave components in places where coworkers can trip over them and be aware of personal safety for yourself and those around you. Lifting Hazards 3:41-3:52 You can also ensure your personal safety by lifting with your legs, not with your back. If you're lifting extremely heavy pieces of equipment, wear a back brace, use a cart, or ask for help. Fire Extinguishers 3:53-4:05 Every room in which you work should be fire suppressed. At a minimum, you should have a Class C fire extinguisher available to you. Class C fire extinguishers are made for electrical fires. MSDS 4:06-4:31 Any component that presents a potential hazard ships with its own MSDS, or Materials Safety Data Sheet. An MSDS explains, among other things, what you should do if you come in contact with an electrical component that's potentially dangerous to you. An MSDS also explains how to properly dispose of equipment. For example, an alkaline battery can be disposed of in the trash a NiCad battery cannot. Summary 4:32-4:47

In this lesson, we talked about safety. Safety is your number one priority. Any time you see a hazardous situation that falls within your responsibility, then you should fix it. If it does not fall within your responsibility, then report it to your safety officer and have it taken care of. Personal safety is your top priority when working with computer components. Keep in mind the following issues that can be hazardous: Hazards Description Power Power hazards can cause electrical shock and burns. Before handling a system component, make sure that it is powered off and that the main power cord is unplugged from the wall socket. Ensure that the grounding pin on a PC power plug is intact. Because newer power supplies constantly pull power from the socket, unplug the system before working on internal components. The power inverter (power supply) converts AC current to DC current. The power supply can retain an electrical charge, even when not plugged in. Replace faulty power supplies instead of trying to repair them. Avoid opening the power supply which houses a capacitor (stores a large charge of electricity).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
