To hold stock in a vise with a "C" clamp when drillng holes on the dril press.
Correct Answer
A. Safe
Explanation
Using a "C" clamp to hold stock in a vise when drilling holes on a drill press is considered safe. The "C" clamp provides a secure grip on the stock, preventing it from moving or slipping during the drilling process. This ensures accurate and precise drilling, reducing the risk of accidents or injuries. Additionally, the vise provides stability and support to the stock, further enhancing safety during the drilling operation.
2.
To brush chips away from the moving drill with the forefinger.
Correct Answer
B. Unsafe
Explanation
Brushing chips away from the moving drill with the forefinger is unsafe because it can result in injury. The moving drill can catch the finger and cause cuts, fractures, or even amputation. It is important to always keep fingers and hands away from moving parts of machinery to avoid accidents and ensure personal safety.
3.
To keep long hair away from the dril press spindle by keeping it tied back or covered.
Correct Answer
A. Safe
Explanation
Keeping long hair tied back or covered while working on a drill press spindle is safe because it prevents the hair from getting caught in the moving parts of the machine. Long hair can easily become entangled in the spindle, causing serious injury or even death. By keeping hair away from the spindle, the risk of accidents and injuries is significantly reduced, making it a safe practice.
4.
To leave a key in the drill press chuck.
Correct Answer
B. Unsafe
Explanation
Leaving a key in the drill press chuck is unsafe because it can lead to accidents or injuries. The chuck is responsible for holding the drill bit in place, and if the key is left inside, it can interfere with the drilling process. It may cause the chuck to become loose or unstable, resulting in the drill bit slipping or flying out unexpectedly. This can cause damage to the workpiece, the drill press, or even harm the operator. Therefore, it is important to always remove the key from the chuck after adjusting or changing the drill bit.
5.
To wear eye protection.
Correct Answer
A. Safe
Explanation
Wearing eye protection is safe because it helps to prevent eye injuries. Eye protection, such as safety glasses or goggles, can shield the eyes from various hazards like flying debris, chemicals, or intense light. By wearing eye protection, individuals can reduce the risk of eye damage and maintain their visual health.
6.
To keep the long end of material being drilled to the left of the operator.
Correct Answer
A. Safe
Explanation
The correct answer is "Safe" because keeping the long end of the material being drilled to the left of the operator reduces the risk of injury. This positioning allows the operator to have better control over the drilling process and minimizes the chances of the material getting caught or tangled in the drill, which could lead to accidents. By keeping the long end to the left, the operator can also have a clearer view of the drilling area and avoid potential hazards.
7.
To wear loose-fitting clothes while operating the drill press.
Correct Answer
B. Unsafe
Explanation
Operating a drill press requires wearing appropriate protective clothing, including close-fitting clothes. Loose-fitting clothes can easily get caught in the moving parts of the drill press, leading to serious injuries. Therefore, wearing loose-fitting clothes while operating the drill press is unsafe.
8.
To talk to someone while operating the drill press.
Correct Answer
B. Unsafe
Explanation
Operating a drill press requires full attention and focus to ensure safety. Talking to someone while operating the drill press can be distracting and may cause the operator to lose concentration, leading to accidents and injuries. It is important to prioritize safety and avoid any distractions while using power tools.
9.
To use caution when you have to reach around a revolving bit.
Correct Answer
B. Unsafe
Explanation
The given answer "Unsafe" is correct because reaching around a revolving bit without caution can be dangerous. Revolving bits, such as those found in power tools like drills or routers, have sharp edges and can cause serious injuries if they come into contact with the hand or fingers. Therefore, it is important to exercise caution and avoid reaching around a revolving bit to prevent accidents and ensure personal safety.
10.
To use dull drill bits.
Correct Answer
B. Unsafe
Explanation
Using dull drill bits is unsafe because they can cause the drill to slip or bind, leading to accidents and injuries. Dull drill bits also require more force to penetrate materials, which can result in the drill operator losing control and causing damage to the workpiece or surrounding objects. Additionally, dull drill bits produce poor-quality holes, making it difficult to achieve accurate and clean results. Therefore, it is important to regularly inspect and replace dull drill bits to ensure safe and efficient drilling operations.
11.
To force the drill through the work as fast as it will go.
Correct Answer
B. Unsafe
Explanation
The phrase "To force the drill through the work as fast as it will go" suggests a reckless and dangerous approach to drilling. Forcing the drill implies applying excessive pressure, which can lead to the drill bit breaking or getting stuck, causing potential harm to the user or damaging the workpiece. This behavior disregards safety precautions and can result in accidents or damage, hence the answer "Unsafe".
12.
To try to stop a piece of work caught on the drill bit.
Correct Answer
B. Unsafe
Explanation
The given answer "Unsafe" is correct because trying to stop a piece of work caught on the drill bit can be dangerous. It can cause the workpiece to spin out of control, leading to potential injuries or damage to the workpiece. It is important to turn off the drill and wait for it to come to a complete stop before attempting to remove any caught material.
13.
To wear gloves to protect yourself from burns.
Correct Answer
B. Unsafe
Explanation
Wearing gloves to protect oneself from burns is unsafe because gloves made of certain materials, such as synthetic materials or those with a low melting point, can actually increase the risk of burns. These gloves can melt onto the skin when exposed to heat, causing further injury. Additionally, gloves can provide a false sense of security and may lead to improper handling of hot objects or chemicals, resulting in burns. It is important to use appropriate protective equipment, such as heat-resistant gloves or other specialized gear, when dealing with potential burn hazards.
14.
To drill into a container that may have contained gasoline or flammable liquid or materials.
Correct Answer
B. Unsafe
Explanation
Drilling into a container that may have contained gasoline or flammable liquid or materials is unsafe because it can potentially cause a spark or ignite the flammable substance, leading to a fire or explosion. It is important to exercise caution and follow proper safety protocols when dealing with potentially hazardous materials.
