Offical Tool Safety Test

Explanation
A rubber mallet is not typically used for putting in nails. Rubber mallets are commonly used in construction and woodworking for tasks that require a softer blow, such as assembling furniture or tapping objects into place without damaging them. However, when it comes to driving nails, a regular hammer is the more appropriate tool as it provides a harder impact necessary to secure the nail properly. Therefore, the statement that you can put in nails with a rubber mallet is false.

Explanation
The correct answer is "back" and "rip". Both "back" and "rip" are types of saws commonly used in woodworking. A back saw is a small, fine-toothed saw with a rigid metal or wooden back, used for making precise cuts. A rip saw, on the other hand, is a saw with larger teeth designed for cutting along the grain of wood. These two types of saws are essential tools in woodworking for different purposes.

Explanation
A rip saw is used to make big cuts in soft wood. Unlike a crosscut saw, which is used for cutting across the grain, a rip saw has larger teeth that are designed to cut with the grain of the wood. This makes it more efficient and effective for cutting through soft wood, allowing for larger and smoother cuts to be made. Therefore, a rip saw is the correct choice for making big cuts in soft wood.

Explanation
A ball peen hammer is used to shape metal because it has a rounded end, called the peen, which is used to strike and shape metal surfaces. The peen allows for precise shaping and forming of metal, making it the ideal tool for metalworking tasks. Claw hammers are primarily used for driving and removing nails, while rubber mallets are used for softer materials and delicate tasks. Therefore, the ball peen hammer is the correct choice for shaping metal.

Explanation
The question asks whether we throw tools or not. The correct answer is "No" because throwing tools is generally not a safe or productive practice. Tools are meant to be used for their intended purpose and throwing them can cause damage, injury, or loss of the tool. It is important to handle tools responsibly and with care to ensure their longevity and effectiveness.

Explanation
If the tool breaks while you are using it, the best course of action would be to inform Mr. DeSilva immediately. By doing so, he can assess the situation and provide a solution or a replacement tool if necessary. It is important to notify the responsible person so that they can address the issue promptly and ensure the safety of everyone involved.

Explanation
The correct answer is "No, not unless Mr. DeSilva gives specific directions to." This answer implies that the students are not allowed to take tools out of the classroom unless they are instructed to do so by Mr. DeSilva. This suggests that there are rules and guidelines in place regarding the use and movement of tools, and the students are expected to follow these instructions.

Explanation
The question asks about the number of types of screwdrivers in our class. The answer is 2, indicating that there are two types of screwdrivers in the class.

Explanation
Slotted screwdrivers are not typically used for scraping stuff off. They are primarily designed for driving slotted screws. Scraping is usually done with tools specifically designed for that purpose, such as scrapers or putty knives. Therefore, the correct answer is "No."

Explanation
Locking pliers can be dangerous to use because they lock down hard on something and can hurt if not used correctly. This is because when the locking mechanism is engaged, the pliers grip tightly onto an object and can apply a significant amount of force. If the user does not handle them with caution or uses excessive force, they may cause injury to themselves or damage to the object being held. Therefore, it is important to follow proper safety guidelines and use locking pliers correctly to avoid accidents.

Explanation
A claw hammer is the correct answer because it has two long pokey things, known as claws, on the back of the hammer. These claws are designed specifically to grip and pull out nails, making the claw hammer the most suitable tool for this task. The ball peen hammer, rubber mallet, and sledge hammer do not have the same claw feature, and therefore are not as effective for pulling out nails.
