Computer Lab Safety Ultimate Quiz: Trivia

Knowing the location of fire extinguishers and fire exits in the computer lab is important because in case of a fire emergency, it is crucial to be able to quickly locate and access these safety measures. Fire extinguishers can be used to suppress small fires before they spread, while fire exits provide a safe route for evacuation. Being aware of these locations can help prevent injuries and minimize damage in the event of a fire.

It is not okay to drink a soda near the computer because if the soda spills, it can damage the computer's hardware and cause malfunctions. Liquids can short-circuit the electronic components and lead to permanent damage. Therefore, it is advised to keep all liquids, including soda, away from the computer to ensure its safety and proper functioning.

Glancing away from the computer screen periodically while working for long periods of time can help prevent eye strain. Staring at the screen for extended periods can cause eye fatigue and discomfort. Taking regular breaks and looking at objects at a distance can help relax the eye muscles and reduce strain. Therefore, the statement is true.

Excessive heat can indeed damage computers. Computers generate heat during operation, and if not properly cooled, this heat can build up and cause components to overheat. Overheating can lead to various issues such as system instability, reduced performance, and even permanent damage to the hardware. To prevent this, it is important to ensure proper ventilation and cooling mechanisms are in place to dissipate the heat generated by the computer.

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. These activities can be disruptive and potentially dangerous, so it is important for students to refrain from engaging in them while in the classroom. Instead, students should focus on appropriate behavior that promotes a positive and productive learning environment.

When a computer is on, it is not fine to move it around as much as you like. Moving a computer while it is powered on can cause damage to the internal components, such as the hard drive or other sensitive parts. It is recommended to shut down the computer properly before moving it to ensure its safety and prevent any potential damage.

It is important to have at least two copies of all your important files because it provides a backup in case one copy gets lost, damaged, or corrupted. Having multiple copies ensures that you can still access your important files even if something happens to one of the copies. This practice helps to safeguard against data loss and ensures that you have a reliable backup in case of emergencies or accidents.

Dust can cause various issues in computers such as overheating, clogging of fans and vents, and damage to internal components. Therefore, it is important to keep dust away from computers to ensure their proper functioning and longevity.

Sitting up straight at the computer is not bad for your back. While it is commonly believed that sitting up straight is the correct posture, research suggests that sitting in a more relaxed and natural position is actually better for the back. Maintaining a slight recline and supporting the lower back with a cushion or lumbar roll can help reduce strain on the spine. Therefore, the statement is false.

A surge protector is designed to protect electronic devices, such as computers, from voltage spikes or surges that can occur in the power supply. These surges can be caused by lightning strikes, power outages, or fluctuations in the electrical grid. By using a surge protector, any excess electric power is diverted away from the computer, preventing damage to its components. Therefore, it is true that using a surge protector can help keep excess electric power from damaging a computer.

Static electricity can destroy the sensitive electronics inside a computer because when there is a buildup of static electricity, it can discharge and create a sudden surge of high voltage. This surge can damage or short-circuit the delicate components of the computer, such as the motherboard, memory chips, or processor. It is important to handle computer components carefully and use anti-static precautions, such as grounding yourself and using anti-static mats or wristbands, to prevent static electricity from causing damage.

This statement is not accurate. Turning off your computer is necessary for various reasons, such as conserving energy, preventing overheating, and allowing for updates and maintenance. Additionally, shutting down the computer when not in use can help prolong its lifespan and prevent potential issues. Therefore, the correct answer is False.

When working inside a computer case, it is important not to touch any of the circuit boards directly. This is because circuit boards are sensitive and can be easily damaged by static electricity or oils from our skin. To prevent any damage, it is recommended to handle circuit boards by their edges when adding or removing them. Therefore, the statement "True" is correct.

Long sessions of typing can put a strain on the muscles, tendons, and nerves in the hands and wrists, leading to repetitive stress injuries. These injuries can include conditions like carpal tunnel syndrome, tendonitis, or trigger finger. The repetitive motions and excessive use of the hands during typing can cause inflammation, pain, and discomfort. Therefore, it is important to take regular breaks, practice proper ergonomics, and perform hand exercises to prevent these injuries.

The student should not open the computer and check the power supply if it will not start. Opening the computer and tampering with the power supply can be dangerous and may cause further damage. It is advisable to seek professional help or consult the manufacturer's troubleshooting guide in such situations.

The statement suggests that if your computer is not working, you can simply begin working on it without reporting it to the teacher. However, this is not true. If your computer is not functioning properly, it is important to inform your teacher or any relevant authority so that they can provide assistance or arrange for a replacement. Ignoring the issue and continuing to work on a faulty computer may hinder your productivity and cause further damage.

Writing down your computer serial number is important because it can be useful in case of theft, warranty claims, or technical support. It helps in identifying your specific device and proving ownership. Additionally, it can be required for insurance purposes or when selling or transferring the computer to someone else. Therefore, it is important to keep a record of your computer serial number.

Placing coats, bags, and other items on the table away from the computers is the correct answer because it helps to prevent tripping hazards. Placing these items on the floor next to the computer or under the chair can lead to accidents and potential injuries. Keeping them on the table ensures a clear and safe workspace, reducing the risk of tripping over them while moving around.

Shutting down the computer by pressing the power button on the computer case is not the recommended method. It is better to use the operating system's shut down option to properly close all running programs and processes. Pressing the power button directly can result in data loss or damage to the system.

Fingerprints contain oils and moisture that can conduct electricity and cause short circuits on computer circuit boards. Therefore, the statement that fingerprints will not cause short circuits is incorrect.
