Bryant High School Computer Lab Safety Test

It is not OK to drink a soda near the computer because the liquid can spill and damage the computer's components. The sugar and other sticky substances in soda can also attract dust and debris, potentially causing the computer to overheat or malfunction. Therefore, it is generally recommended to keep liquids, including soda, away from electronic devices to prevent any accidents or damage.

Knowing the location of fire extinguishers and fire exits in the computer lab is important because in the event of a fire, it is crucial to be able to quickly locate and access these safety measures. Fire extinguishers can help to suppress small fires before they spread, while fire exits provide a safe escape route for individuals to evacuate the building. By being aware of their locations, individuals can respond effectively and efficiently in case of an emergency, potentially preventing injuries or further damage.

Excessive heat can damage computers because it can cause the internal components to overheat, leading to malfunctions or even permanent damage. Heat can cause the computer's processor to slow down or shut down completely to prevent damage. It can also cause the hard drive to fail or the motherboard to warp. To prevent damage, it is important to keep computers in a well-ventilated area and ensure proper cooling mechanisms are in place, such as fans or liquid cooling systems.

Having at least two copies of all important files is crucial because it provides a backup in case one copy gets lost, damaged, or corrupted. This redundancy ensures that even if one copy is inaccessible or compromised, the other copy can still be retrieved. By maintaining multiple copies, the risk of data loss is significantly reduced, increasing the chances of preserving important files and information.

Glancing away from the screen periodically when working at a computer for long periods of time is important to avoid eye strain. Staring at the screen for extended periods can cause eye fatigue, dryness, and discomfort. By looking away and focusing on objects at different distances, the eyes can relax and adjust, reducing the strain on the eye muscles. This practice also helps prevent other issues such as headaches and blurred vision.

Dust can cause various problems for computers. It can clog the cooling system, leading to overheating and potential damage to components. It can also interfere with the proper functioning of fans, causing them to work harder and potentially fail. Additionally, dust can accumulate on circuit boards and connectors, leading to poor connections and potential malfunctions. Therefore, it is important to keep dust away from computers to ensure their optimal performance and longevity.

Sitting up straight at the computer is often perceived as the correct posture to maintain good back health. However, this statement is false. Sitting up straight for prolonged periods can actually strain the back muscles and lead to discomfort or pain. It is recommended to maintain a neutral posture that supports the natural curves of the spine, which may include slight reclining or using ergonomic chairs to alleviate back stress.

When a computer is on, it is not fine to move it around as much as you like. Moving a computer while it is on can cause damage to the internal components, such as the hard drive, which can lead to data loss or system failure. It is recommended to turn off the computer properly before moving it to ensure its safety and prevent any potential damage.

Static electricity can destroy the sensitive electronics inside a computer because it can cause a buildup of electric charge on the surface of objects. When this charged object comes into contact with a computer component, it can discharge a high amount of electrical energy, damaging or even completely destroying the delicate circuitry. This is why it is important to take precautions such as grounding oneself and using anti-static equipment when working with computers to prevent any potential damage caused by static electricity.

The correct answer is "not include running and horseplay." This means that running and horseplay should not be part of the behavior in the classroom. This is because running and horseplay can be disruptive and dangerous, potentially leading to accidents or injuries. In order to maintain a safe and productive learning environment, it is important for students to refrain from engaging in such activities in the classroom.

You should report any issues with your computer to the teacher so that they can provide assistance or find a solution. Ignoring the problem and continuing to work on it may lead to further complications or hinder your progress. It is important to communicate any technical difficulties to ensure a smooth learning experience.

Using a surge protector is an effective way to safeguard your computer against damage caused by excess electric power. Surge protectors are designed to absorb and divert excessive voltage spikes, preventing them from reaching your computer and potentially causing harm to its components. By using a surge protector, you can provide an additional layer of protection for your computer and ensure its longevity and safe operation.

When working inside a computer case, it is important not to touch any of the circuit boards directly. This is because touching the circuit boards can cause static electricity to discharge, which can damage the sensitive electronic components on the board. To prevent this, it is recommended to handle the circuit boards by their edges when adding or removing them from the computer case.

Long sessions of typing can put excessive strain on the muscles, tendons, and nerves in the hands, leading to repetitive stress injuries (RSIs). RSIs are caused by repetitive movements, such as typing, and can result in conditions like carpal tunnel syndrome or tendonitis. These injuries can cause pain, numbness, tingling, or weakness in the hands and wrists. Blisters on the fingers may be a temporary issue due to friction, but they are not a common symptom of long typing sessions. Deafness is unrelated to typing and not a typical consequence of prolonged typing.

The statement "You should never turn your computer off" is incorrect. It is important to turn off your computer when it is not in use to save energy, prevent overheating, and prolong the lifespan of the computer. Additionally, regularly shutting down your computer allows for necessary updates and maintenance to be performed. Therefore, the correct answer is False.

The student should not open the computer and check the power supply if the computer will not start. Opening the computer and checking the power supply can be dangerous and may void the warranty. It is recommended to contact a professional technician or the manufacturer for assistance in troubleshooting and fixing the issue.

Shutting down a computer by pressing the power button on the computer case is not the recommended method. This can lead to data loss and potential damage to the operating system. It is advised to use the proper shutdown procedure through the operating system's shutdown option or by using the Start menu.

Writing down your computer serial number is important for various reasons. It can be helpful in case your computer gets stolen or lost, as you can provide the serial number to the authorities or your insurance company for identification purposes. Additionally, the serial number may be required when contacting customer support for technical assistance or warranty claims. Therefore, it is important to keep a record of your computer's serial number for future reference.

Placing coats, bags, and other items on the floor next to the computer can create a potential tripping hazard. Placing them on the table away from the computers is a safer option as it keeps the walkway clear and reduces the risk of accidents.

Fingerprints will cause short circuits to computer circuit boards. This is because fingerprints contain oils and salts that can create a conductive path between two or more electrical components on the circuit board, leading to a short circuit. This can potentially damage the circuit board and disrupt the proper functioning of the computer. Therefore, it is important to handle circuit boards with clean hands and avoid touching the sensitive components to prevent short circuits.
