It is important to follow proper procedures and seek permission before making any changes to the programs or files on a computer.

Injuries have to be reported to the instructor as soon as they happen because immediate action is required to ensure the safety and well-being of the injured person. Reporting the injury promptly allows the instructor to assess the severity of the injury and provide appropriate medical attention or first aid.

Delaying the reporting of injuries can result in a delay in receiving necessary medical assistance, which could worsen the condition or lead to complications.

Teachers are responsible for the overall functioning of their classrooms, which includes ensuring that tools and machines are in working order. They have the authority to report any issues with tools or machines to the appropriate maintenance personnel or department.

Therefore, the teacher is the most appropriate person to report tools or machines not working.

Sharp tools should be carried with the cutting edge facing down to minimize the risk of accidents or injuries. When the cutting edge is facing down, it is less likely to come into contact with any unintended objects or body parts, reducing the chances of cuts or lacerations. This position also ensures better control and stability while carrying the tool, preventing it from slipping or falling.

Hot glue is not safe to touch because it is typically heated to high temperatures in order to melt and become adhesive. This can cause burns or skin irritation if it comes into direct contact with the skin. It is important to use caution and protective measures, such as gloves or tools, when handling hot glue to avoid any potential harm.

Hand tools should not be placed in pockets as they can cause injury or discomfort. Placing tools in pockets can restrict movement, cause imbalance, or lead to accidental activation or damage.

It is important to never leave a safety zone if a machine is still running because it can pose serious risks to personal safety. Moving away from the safety zone while a machine is in operation increases the chances of accidents or injuries.

Therefore, the statement "Never leave a safety zone if a machine is still running" is true.

It is important to report damage to computers or equipment, regardless of whether the teacher is busy or not. Reporting damage ensures that the necessary repairs or replacements can be made promptly, preventing further damage or inconvenience to other students.

Therefore, it is crucial to report any damage, even if the teacher is busy, to ensure the smooth functioning of the classroom and the equipment.

It is not safe to talk and distract students when they are using tools and machines. This can lead to accidents and injuries as their focus and attention should be on the task at hand.

It is important to check the condition of tools and machines before using them to ensure they are safe and in proper working order. Failing to do so can lead to accidents, injuries, or damage to the equipment. Therefore, the statement "You do not have to check the condition of tools and machines before you use them" is false. It is necessary to inspect tools and machines before use to maintain a safe working environment.

Tools cannot hang over the edge of a workbench because it can be dangerous and may cause accidents. It is important to keep tools properly stored and organized to ensure a safe working environment.

Safety glasses are a crucial protective measure in a lab setting. They help protect the eyes from potential hazards such as chemicals, flying objects, or debris.

Therefore, the statement that safety glasses must be worn in the lab unless instructed otherwise by the teacher is true.

The correct answer is "All of the above" because the statement mentions three conditions that need to be fulfilled before using any tool or machine. These conditions include having a safety demonstration, passing the machine safety test with a perfect score, and obtaining permission. Therefore, all three conditions must be met in order to use any tool or machine.

Emergency shut off switches are designed to quickly and effectively stop the power supply to machines in emergency situations. This is crucial for ensuring the safety of individuals working with or around the machines. By cutting off the power, these switches help prevent accidents, potential damage, and further escalation of any hazardous situations.
