What is the minimal Personal Protective Equipment that must be worn when operating an Angle Grinder?

Dust mask, Overalls and Earmuffs
Safety Glasses
Safety Glasses and Earmuffs
Earmuffs and Safety Gloves

Correct Answer

A. Safety Glasses and Earmuffs

Explanation

When operating an Angle Grinder, it is important to protect both the eyes and the ears. Safety Glasses are necessary to shield the eyes from any flying debris or sparks that may occur during operation. Earmuffs are essential to protect the ears from the loud noise produced by the grinder. While a dust mask and safety gloves may be advisable for additional protection, the minimal Personal Protective Equipment required is Safety Glasses and Earmuffs.

The angle grinder is a portable electric grinder that uses an_____ _ for grinding away material

Correct Answer
Abrasive
Disk

Explanation
The angle grinder is a portable electric grinder that uses an abrasive disk for grinding away material. The abrasive disk is a tool with a rough surface that is designed to remove material through friction. It is commonly used in various applications such as cutting, grinding, and polishing. The abrasive disk is attached to the angle grinder and rotates at high speeds, allowing it to effectively grind away material from surfaces.

4.

Grinding Disks need frequent replacement.

True
False

Correct Answer

A. True

Explanation

Grinding disks need frequent replacement because they are used to remove material from a surface through abrasion. As they are constantly in contact with the workpiece, they gradually wear down over time. The abrasive particles on the surface of the disk become dull and less effective, resulting in reduced grinding performance. Additionally, the heat generated during grinding can cause the disk to warp or crack, further necessitating replacement. Regular replacement of grinding disks ensures optimal performance and safety during grinding operations.

What should you ensure before using the Angle Grinder?

The disk is not defected.
The disk being used matches the size and RPM of the machine.
The cord has an up-to-date ticket and isn't broken or frayed.
The securing nut is fastened tight.
All of the above

Correct Answer

A. All of the above

Explanation

Before using an Angle Grinder, it is important to ensure several things. Firstly, the disk should not be defected, as a defected disk can be dangerous and cause accidents. Secondly, the disk being used should match the size and RPM (rotations per minute) of the machine to ensure proper functioning. Thirdly, the cord should have an up-to-date ticket, indicating that it has been inspected and deemed safe for use, and it should not be broken or frayed. Lastly, the securing nut should be fastened tight to ensure that the disk is securely attached to the machine. Therefore, all of the above precautions should be taken before using an Angle Grinder.

Never use a Grinder without the disk guard. Why is this so?

It protects you from flying debris.
It prevents you from using an incorrect size disk.
All of the above
None of the above

Correct Answer

A. All of the above

Explanation

Using a grinder without the disk guard can be dangerous for several reasons. Firstly, it protects the user from flying debris that may be created during the grinding process, preventing potential injuries. Secondly, the disk guard ensures that only the correct size disk is used, which is important for safety and preventing damage to the grinder or the workpiece. Therefore, all of the above reasons explain why it is necessary to never use a grinder without the disk guard.

7.

Always match the maximum RPM of the disk with the grinder.

True
False

Correct Answer

A. True

Explanation

It is important to always match the maximum RPM of the disk with the grinder to ensure safe and efficient operation. Using a disk with a higher RPM rating than the grinder can lead to the disk spinning too fast and potentially causing accidents or damage. On the other hand, using a disk with a lower RPM rating may result in poor performance and ineffective grinding. Therefore, it is crucial to select a disk that matches the maximum RPM of the grinder to ensure compatibility and safety.

8.

The grinder shouldn't be used as a cutting device if there's another cutting tool available.

True
False

Correct Answer

A. True

Explanation

Using a grinder as a cutting device can be dangerous and inefficient compared to using a proper cutting tool. Grinders are primarily designed for grinding and shaping materials, not for precise cutting. They have a rotating abrasive wheel that is not ideal for making clean cuts and can cause the material to splinter or shatter. It is always recommended to use the appropriate cutting tool for the task at hand to ensure safety and achieve better results.

Rate this question:

9.

The Grinder Disk should be spinning before making contact with the material being ground or cut.

True
False

Correct Answer

A. True

Explanation

It is important for the grinder disk to be spinning before making contact with the material being ground or cut in order to ensure smooth and efficient cutting or grinding. If the disk is not spinning, it may cause uneven cuts, damage to the material or the grinder itself, and increase the risk of accidents. Therefore, it is necessary to ensure that the disk is spinning before starting the grinding or cutting process.

Rate this question:

10.

The Grinding disk can be used for cutting material.

True
False

Correct Answer

A. False

Explanation

The grinding disk is not designed for cutting material. It is primarily used for grinding and smoothing surfaces. Cutting disks, on the other hand, are specifically designed for cutting through materials. Therefore, the statement that the grinding disk can be used for cutting material is false.
