1.
The speed of the machine is not important for safe operation.
Correct Answer
B. False
Explanation
The statement is false because the speed of the machine is indeed important for safe operation. The speed at which a machine operates can directly impact its efficiency, effectiveness, and safety. If a machine operates at an excessively high speed, it can lead to increased friction, overheating, or even mechanical failure. On the other hand, if a machine operates at an extremely slow speed, it may not be able to perform its intended function efficiently. Therefore, the speed of a machine is a crucial factor in ensuring safe and optimal operation.
2.
A space of one inch is safe between the tool rest and the work.
Correct Answer
B. False
Explanation
A space of one inch is not safe between the tool rest and the work. It is important to have the tool rest as close as possible to the work in order to provide support and stability while working. Leaving a larger gap increases the risk of the workpiece being unstable and potentially causing accidents or injuries.
3.
Eye protection is not necessary during operation.
Correct Answer
B. False
Explanation
Eye protection is necessary during operation to prevent any potential hazards or injuries to the eyes. Operating machinery or performing tasks that involve flying debris, chemicals, or bright lights can pose a risk to the eyes. Wearing appropriate eye protection such as safety glasses or goggles is essential to ensure the safety and well-being of the individual. Therefore, the statement that eye protection is not necessary during operation is false.
4.
Dull tools may be used.
Correct Answer
B. False
Explanation
Dull tools are not recommended to be used as they can be less effective and potentially dangerous. Using sharp tools is generally safer and more efficient.
5.
It is not safe to feel for smoothness while turning.
Correct Answer
A. True
Explanation
Feeling for smoothness while turning can be unsafe because it can distract the driver from focusing on the road and other potential hazards. Instead, it is important to rely on visual cues and maintain proper hand positioning on the steering wheel to ensure safe and controlled turns. By keeping the hands at the proper positions, the driver can have better control over the vehicle and be prepared to react to any unexpected situations that may arise.
6.
The tool rest should be removed while sanding.
Correct Answer
A. True
Explanation
The tool rest should be removed while sanding to ensure safety and prevent any potential accidents or damage. The tool rest is designed to support the tool and provide stability during cutting or shaping operations. However, during sanding, the tool rest can interfere with the sanding process and cause the sandpaper to catch or snag on it, leading to potential injury or damage to the workpiece. Therefore, it is important to remove the tool rest before starting the sanding operation.
7.
It is safe to turn work that is not balanced.
Correct Answer
B. False
Explanation
It is not safe to turn work that is not balanced. Unbalanced work can cause instability, vibrations, and potential accidents. It is important to ensure that work is properly balanced before attempting to turn it to avoid any potential hazards.
8.
Long sleeves may be worn while operating.
Correct Answer
B. False
Explanation
The statement suggests that long sleeves can be worn while operating. However, in many industries and workplaces, it is not recommended to wear long sleeves while operating machinery or equipment. Long sleeves can get caught in moving parts, leading to serious accidents or injuries. Therefore, it is advisable to avoid wearing long sleeves while operating to ensure safety.
9.
The cutting tool may be held loosely.
Correct Answer
B. False
Explanation
The cutting tool should not be held loosely as it can lead to accidents or ineffective cutting. It is important to have a firm grip on the tool to ensure control and accuracy while cutting. Holding the tool loosely can result in slipping or losing control, which can cause injuries or damage to the material being cut. Therefore, the statement is false and the cutting tool should be held securely.
10.
The hair should be confined while operating the machine.
Correct Answer
A. True
Explanation
It is important to confine the hair while operating the machine to prevent any accidents or injuries. Loose hair can get caught in the machine's moving parts, leading to serious harm. By confining the hair, such as tying it back or wearing a hairnet, the risk of accidents can be significantly reduced. Therefore, the statement "The hair should be confined while operating the machine" is true.
