Common OHS practices and using the right tools for computer hardware.

1. Occupational Health And safety

2. Introduction In any field, we prioritize the health and safety of the people within the workplace. Without any standards and precautions, this will result to a lot of incidents that may harm people and in the worst case scenario, die in an unfortunate event. Having Occupational Health and Safety Standards help us avoid most of the problems that we will face in our workplace. If you would notice most technological fields have these standards which we are compelled to follow.

3. OHS Standards refers to the rules, policies, legislation, procedures, and activities that are geared towards protecting the health and welfare of all the people in our working environment. Specially in this course, we should follow the common safe practices in computer servicing and installation. There are a lot of things that we don’t know and did not follow even in holding or handling devices around us. Here are common practices on when we are installing and servicing computers. Occupational Health and Safety Standards

4. Common OHS Practices

5. Don’t Work Alone . This is applicable to all workplaces. Having someone watching you and taking care of you will be beneficial specially when your work involves electricity, mechanical equipment, power tools, and even chemicals. Someone should always be there to help you in case of emergency. Common OHS Practices

6. Turn off the device before working on it. This is the most obvious one but most people won’t follow this and simply forget. Being confident in what we do sometimes leads us to a sparkling pain. Before working on any electrical device, remember to plug it off or let it discharge before handling the device. Also use PPEs but more on that later.

7. Take away any liquids. Whether this will be water, aerosols, coffee, etc. don’t let any liquid get close to an electrical device. Liquids are highly conductive and will cause some parts of the device to short circuit.

8. Like liquids, Tools can be conductive. Some tools are conductive as well and can cause short circuit. Be careful in using tools because most of it is made out of metal and they are conductive as well

9. Discharge yourself/ Ground yourself. Most people would think that this will cause you pain and electric shock because of the word “ground” in it, but this is an easy step to accomplish. Most of the system units have a metal casing that we can use to discharge ourselves. This helps us disperse the electric charge building up in our bodies. Also remember to wear shoes.

10. Don’t be forceful. Sometimes we have a lot of screws, bolts, and nuts in out device and when we assemble and disassemble them it might get confusing to put it back together since those are not labelled. If it doesn’t fit, don’t force it, but if it’s in the right place, don’t screw them too tightly

11. Clean - Clean the area before and after using it. Cleaning before using the area will assure you that dust or anything will not be in contact with your components. Cleaning after will help you see if there are any components left behind and makes your service better .

12. Hold components appropriately. Most of the parts of the system unit is exposed and the pcbs are sensitive to conductance like the motherboard, RAM, and CPU. We have to hold or handle these components carefully. People would hold these on the edges and carefully not touch the integrated circuits. Some people would use gloves to hold these components

13. Always Wear Personal Protective Equipment. Most of you might have seen PPEs around hospitals and energy plants. People are required to use this equipment to assure the safety of the technician/ worker. These might include; gloves, masks, helmets, lab coats, earplugs, and many more

14. Make sure the pins are aligned properly- Most of the components are connected via pins which are mostly made with a sort of metal that connects each component together. Some components have specific number of pins and they are not that strong. Pins can bend when given enough force. So be careful. Check if the component that you will plug has the appropriate number of pins and also if they align to the connector properly.

15. Contingency measures during workplace accidents. We should expect the worst in most of situations to generate plans that will guarantee safety without compromising the work. Having plans to execute when there is a problem or accident will always lessen the damages. We should consider many types of emergencies as well.

16. Clean the components properly. We have to use proper equipment to clean our components. Commonly it is advised to bring a brush in servicing a computer to clean the edges of each components but sometimes the fibers get left behind when the cleaning process is done. Some people use compressed air or a blower to clean a computer system. And Don’t Blow Air Using Your Mouth!

17. What are some potential hazards you've identified in our workplace? What steps do you take when working around potential hazards? What's one way that management can help you prevent injury?

18. Using the right Tools

19. Electrostatic Discharge tools (ESD)

20. Hand Tools – the tools in computer assembly are commonly small hand tools. They are individually or packaged in a computer repair kit. These vary in sizes, quality, and price.

21. Cleaning Tools.

22. Diagnostic Tools We should also have tools that will help us configure and test components to predict issues before application or before we turn on the computer. With these tools we can test the network connection, visual output, and voltage and current of the motherboard/ components.

23. A power supply tester is  an electronic device used to test how well a computer power supply is functioning . This type of testing is often performed as part of maintenance on a computer and can be used to try to determine the source of a computer problem. A network cable tester is  an electronic device that measures the conductive between two ends of a cable . It also checks and measures signal for correct wiring.

24. Toner probe: The toner part is connected to a cable at one end using specific adapters, such as an RJ-45, coaxial, or metal clips. The toner generates a tone that travels the length of the cable. The probe part traces the cable. When the probe is in near proximity to the cable to which the toner is attached, the tone can be heard through a speaker in the probe. Loopback adapter:   is also called a loopback plug, tests the basic functionality of computer ports. The adapter is specific to the port that you want to test.
