Give at least 5 examples of improper use of hand tools

1. Cutting toward your body when using hand cutting tools.

2. Hold the nail with your fingers while hammering.

3. Using a tool not sized properly for the job.

4. Carrying sharp tools in your pocket.

5. Placing your hands near the sharp end of the tools.

1. Keep all tools in good condition with regular maintenance.

2. Use the right tool for the job.

3. Examine each tool for damage before use and do not use damaged tools.

4. Operate tools according to the manufacturers’ instruction.

5. Provide and use properly the right personal protective equipment.

1. Cost – power tools are expensive compared to their hand tool counterpart. Owing to the cost of production.

2. Safety – hand tools are relatively safer than power tools, mainly because of their lack of power and automation. However, you can still get injured using both types of tools. But power tool injuries are severe when compared to hand tools.

3. Speed – power tools are much faster than hand tools in two ways. First, there is the benefit of being able to perform a single task faster. Secondly, there is the benefit of virtually unlimited energy available at your disposal. Power tools get the work done with less exertion of strength when compared to hand tools.

4. Energy source – in the case of a hand tool, all of the energy comes from the tool operator, in the case of power tools, the vast majority of it comes from an external power source.

5. Precision -  power tools will be more precise in terms of getting the same task done right repeatedly, hand tools are oftentimes more precise in their level of control.

Hand tools are used manually while power tools are used with an aid of an external force/energy.

Power tools also have motors and other mechanisms that allow them to run more efficiently and more powerfully than hand tools.

Using a power tool in a specified job is quicker as well as require less effort from the user than the hand tool.  

Parts of power tools are most likely to fail and can halt the operation over a period of time than hand tools.

Power tools are more expensive than the hand tools due to its complexness and the wide range of task it can make.

a.)    Give at least 5 examples of improper uses of hand tools. 

It is vital to use the befitting screwdriver size. I bet you don’t know there are four types of Phillips screwdrivers. This runs from #0 to #4. #0 is the smallest Philip size, but #2 and #1 are the most prevalent. #4 are not in vogue anymore, but #1-3 are found in almost everything. While a #2 driver would fit into a #3 size screw, the reverse doesn’t work. Now, the screwdriver head must be snugly fit before you start. If it is too thick, it will be strip. The same happens if it is too narrow.

Most people make the mistake of using ratchets and wrenches for high-impact tasks supposedly devoted to hammers. Wrenches and ratchets don’t have the impact force of hammers, being too light and with round edges. When used, your wrench can not only dent your sheet metal, it can also hurt your fingers severely.

 

Some of the most common accidents involving utility knives include cutting more than your utility knife can handle, using a knife with a dull blade, drawing your utility knife towards your body rather than away, and storing the knife incorrectly with an extended blade. It is essential to use the right blade size when using retractable blades. Also, if the retraction mechanism of your knife is faulty, change it immediately. Many craftspersons have been seriously injured from blades not retracting properly into the handle. If you can afford it, use self-retracting knives that automatically retract when you do not use the utility knife.

 

Pliers are versatile. From bending to cutting and holding objects, pliers get the job done. But pliers are not wrenches. Wrench – not pliers – should be used when you have bolts and nuts to turn. Tasks involving tightening and loosening bolts and nuts should be left to wrenches. Compared to pliers, wrenches provide better torque. Unlike your plier, a wrench is far less likely to damage fasteners or round them.

 

When you replace your pry bar with your screwdriver, you are almost sure to get the shank bent. But that is not all the damage you do. You can also end up breaking the shank and hurting your hand with the broken pieces. It is not like buying a small iron pry bar will not get you bankrupt either.

 

b.)    Give at least 5 examples of proper use of hand tools.  

 

·         Regularly inspect tools to make sure they are in good shape and fit for use.

·         Be sure to maintain your tools by performing regular maintenance, like grinding or sharpening. Always follow the manufacturer’s instructions.

·         Wear appropriate personal protective equipment, like leather gloves.

·         Use the right tool for the job. In other words, don’t try to use a wrench as a hammer.

·         Make sure that your feet are planted on a stable surface.

 

c.) Explain difference between hand tools and power tools at least 5.

 

There are two things to bear in mind when it comes to accuracy. While power tools are more exact when it comes to repeating the same work, hand instruments are typically more accurate in their degree of control. To put it another way, if you want to drill the same hole into a piece of material again and over again, a drill press is the way to go. However, if you need to drill a very small hole into a delicate piece of material, a manual hand drill may be preferable. 

 

In two respects, power tools are substantially faster than manual tools. To begin with, there is the advantage of being able to do a single work faster. Cutting a board using a circular saw, for example, is far faster than cutting a board with a handsaw. The second advantage is that you have nearly infinite energy at your disposal. Power tools, unlike muscles, do not require nearly as much "relaxation time," allowing you to work with less breaks and complete tasks in fewer days. When opposed to manual tools, power tools allow you to perform more work with less effort. 

 

The fact that while power equipment can be operated for lengthy periods of time, doing the same work manually with hand tools for the same amount of time can be difficult. 

 

The apparent distinction between hand and power tools is where the energy to do the operation comes from. While all of the energy in a hand tool originates from the tool operator, the great majority of the energy in power tools comes from an external power source. An air compressor, a power outlet, a battery, or gas might all be used as a power source. Even with most power tools, the operator must use a significant amount of energy in order to move the tool, press it against the workpiece, or move the workpieces around (in the case of a router table, for example). 

 

Because of their lack of power and automation, hand tools are considered to be safer than power tools. Both sorts of instruments, however, have the potential to cause injury. When compared to hand tools, however, power tool injuries are more serious. As a result, before using any tool, whether electric, manual, or gas-powered, make sure you have the essential safety equipment and perform the necessary safety measures.
