Introduction:
Tools are a common part of our everyday lives and are present in nearly every household and industry. These tools help us to perform many tasks that would be difficult or impossible to do without them. However, when tools are used improperly or are poorly maintained, even the lowly screwdriver can cause significant personal injury. Special attention toward hand tool safety is necessary in order to reduce or eliminate these hazards. This exercise will help you to assess the potential hazards and put controls in place to mitigate such hazards.

Engineers Toolkit / Hand Tool IQ Resource Document / Hand Tool IQ ExercisePliers:
One of the most important considerations when using pliers is that you make the correct selection for the job being done. If you use the wrong type of pliers, you may injure yourself and almost certainly damage your work. Pliers that are too large can damage a fastener and using pliers that are too small may damage the tool. Many a technician has acquired a painful blood-blister as an improperly gripped pair of pliers slipped off a fastener and pinched a tender part of a hand. It hurts and that little purple spot never goes away. There are many different kinds of pliers to consider. Pliers are also an essential wiring tool.Never use a pair of pliers when you have a wrench that will do the job. Wrenches are always better than pliers.
Procedure:
Before you get started, print out and then answer the problems on this exercise sheet. Study the following tools using the Hand Tool IQ Resource and refer to your listing of Research Resources. Make notes regarding the nomenclature listed about, hand tool care and safe use using the Learning Log.
Groove Joint Pliers / Wire Strippers / Hemostats / Needle Nose Pliers / Chain Nose Pliers / Mini Diagonal Cutters1.Whichtype of pliers are delicate and made for holding, manipulating, and bending tiny parts?
2.Why do you have to adjust wire strippers before you use them?
3.What is another name for long-nose pliers?
4.What is the name of the pliers that can be adjusted to various opening widths and used to secured and turn medium to very large nuts and bolts?
5.What is the advantage of insulated handles on pliers?
Drivers:
Drivers are made in various shapes and lengths and are designed to secure specific types of threaded fasteners. The size of a driver is determined by the length of the shaft and the size of the tip or its socket. The size and shape of the blade tips on screwdrivers vary from narrow parallel-sided tips to wide, tapered tips. Some drivers have special tips for cross-slotted, recessed screws or bolts, and clutch-bit screws as well as bolts and nuts. Some drivers are even provided with a ratchet in the handle to make them easier to use.
Always use a driver that fits the screw slot or nut exactly. A poor fitting driver can damage the screw and driver, slip off the screw, and cause personal injury. If a tight screw with a damaged slot can be backed out partially, it may possible to remove it completely by turning it with a pair of pliers. When a driver becomes chipped, or the gripping edges become rounded, or when other damage occurs so that it doesn't fit the screw…Don't use it. The tool must be repaired or discarded. Remember that drivers are used for one purpose only - to turn threaded fasteners. They must never be used for any other task.
Procedure:
Study the following fasteners using the Tool IQ Resource or the Research Resources. Make notes regarding the proper tools used to secure these fasteners as well as their care and safe use using the Learning Log.
Identify the best driver used to secure and adjust the following fasteners and devices:
Fastener / Tool Name / Fastener / Tool NamePan Head /
Trim Pot

Pan Head /
Hex Nut
Wrenches:
As with every tool, one of the most important considerations when using wrenches is to make the correct selection for the job being done. This is where specific knowledge and practice with tools comes in handy. If you use the wrong type of wrench, you may injure yourself, damage the tool and almost certainly damage your work. Selecting a wrench that is too large can damage a fastener and using a wrench too small may damage the wrench.
Procedure:
Study the following fasteners using the Tool IQ Resource and the links listed in the Research Resources. Make notes regarding the proper tools used to secure these fasteners as well as their care and safe use using the Learning Log.
Identify the best wrench used to secure the following fasteners:
Fastener / Tool Name / Fastener / Tool NameCap Head Bolt /
Button Head Screw
Square Nuts /
Set Screws
Cap Head Screw /
Machine Screw
Miscellaneous and Special Tools:
There are many miscellaneous and special tools you’ll need to inspect, service, and support the modeling of engineering and design projects. These tools fall into this category because they can’t be considered as either a pliers, driver, or wrench type of tool. Their use is more specialized which makes them irreplaceable in particular situations. Remember… Using substitutes runs the risk of personal injury, damaged tools or damaged work. Always use the right tool for the job.
Procedure:
Study the following tools using the Hand Tool IQ Resource and the links listed in the Research Resources. Make notes regarding their care and safe use using the Learning Log and answer the following questions.
Multi-meter / Parts Box / Zip-Lock Bags / Parts Holder / Pocket Knife / Needle FilesInspection Mirror / Pen Light
- Make a list the four types of measurements a multi-meter can test.
- What kind of tool features a tang?
- What tools in your toolkit can be used to temporarily store parts while repairing equipment?
- Which of these tools typically features a magnet for retrieving dropped steel fasteners?
- Which of these tools can easily break if the wires are over-extended?
Toolkit Inventory:
One of the most important employability skills you’ll need to master is the care and use of materials. The Engineer’s Toolkit is a good place to start practicing. Anytime an engineer goes on a job they’ll need a complete toolkit. There’s nothing more frustrating to an engineer than arriving at a job site, starting work, and then realization they’re missing a needed tool or something else they require. Always inventory your toolkit before heading out on a job. You’ll also need to inventory it when you turn it in. It’s important to note that your program may have a different type of toolkit than what’s featured in this module. That’s OK. Just use the inventory sheet that came with your toolkit to conduct this exercise.
Procedure:
Print out the toolkit Inventory Sheet for the Engineer’s Toolkit used in your engineering program. Complete the inventory sheet by going down the list of tools item-by-item making note of any missing or damaged items from the kit. Report any missing, damaged or extra items when you show the completed inventory sheet to your instructor.
Conclusion:
It’s been said that it’s our use of tools to solve problems that sets us apart from other animals. Although other animals make and use tools, it is uniquely human to collect them, categorize them and then display them on huge pegboards with all the tools outlined with shadows so you know if one is missing. It’s important to know tools by their proper name and to use them correctly and safely. To earn the respect of professionals you will need to know that there is no such thing as a “flat-head” or even a “flat-tip” screwdriver. It’s either called a “standard” or “common” screwdriver. Using the wrong name will earn you nothing but ridicule and remember… It is better to have tools you don’t need than need a tool you don’t have.

Exercise2 – PPE and Laboratory Safety
Objective:
Upon the completion of this exercise, you will identify, understand and properly apply Personal Protective Equipment (PPE) and safety procedures in a shop or lab environment. To demonstrate your knowledge,you will match the appropriate PPE with the task being performed. You’ll also demonstrate how to respond to various types of emergencies should one occur in the engineering lab.
Information:
Before we start, it’s important to note that all injuries are preventable. However, they are also probable and even likely to occur based upon the circumstance. There are three basic elements to a safety program that reduces the possibilities of mishap and mitigates the damages should an injury occur.
- Personal Protective Equipment (PPE)
- Safety Rules
- Emergency Response Procedures
Driving is a good example of this three prong approach to safety. Drivers and passengers are protected by specialized PPE equipmentin vehicles when they use seatbelts, drive vehicles that are safe and feature an airbag safety system. When drivers obey traffic laws, they are following safety rules that keep everyone safer. Should a collision occur, emergency responders step in to render first aid, clear the wreckage and provide ambulance service if necessary.
This is also the approach we will use in our classroom. It is the way we do business. Everyone is required to properly use the appropriate Personal Protective Equipment (PPE). They are required to be knowledgeable of and adhere to the Laboratory Safety Practices. You are also an important member of the Emergency Response Team should there be a fire, an injury or even a leaking battery.
The chemicals, paint, andbatteries, etc. used in your lab should be properly stored in according to school’s fire safety regulations and the Material Safety Data Sheet (MSDS). The proper type and number of fire extinguishers should be positioned at the entrances to the lab. Flammable materials should be stored in a special fireproof cabinet that will not explode if the materials inside it catch on fire. Acids should be stored in a special acid-proof cabinet as well. Flammables, acids and combustibles should never be stored together. The MSDS library, first aid kit and battery-leak response kit should be stored away from the materials cabinets and must be conspicuously labeled and easily accessible by everyone. All students should know how administer basic first aid as well as properly use a fire extinguisher and the battery-leak response kit.

Questions and Tasks:
- Use the Research Resources the Laboratory Safety Practices to develop a detailed definition for each of the terms found in the Nomenclature section of this document. Many words have multiple definitions. Some of which may have nothing to do with the field of Safety or Robotics Engineering. Make sure your definition falls within the context of this lesson.
- After completing the training on the ABC’s of Portable Fire Extinguishers closely examine the fire extinguisher in your shop or lab.
- What type of fire extinguisher is it?
- What class of fire or fires is it designed to extinguish?
- Is it properly serviced and in good repair?
- Is it the right type of fire extinguisher for your room?
- Complete the training on OSHA standards for PPE. Using a school football team as an example, create a list of Personal Protective Equipment (PPE) that keep a player safe and then identify the part of the body the PPE protects.
- Thoroughly study the Laboratory Safety Practices for this course. Place a checkmark in the columns indicating the most appropriate PPE for the task being completed.

- Create a poster suitable for display in the shop or lab. The poster will list the Nickel Cadmium, Lithium Ion, Alkaline and Lead-Acid batteries on one axis of a chart and the step-by-step procedures for dealing with a battery leak on the other axis.
Conclusion:
Safety is sometimes a difficult concept for instructors to teach and for students to learn. We’re a resilient species that heals quickly and after all, you must still be alive if you are reading this material. There’s a lot to be said for survival instinct, self-preservation and good old-fashioned fear to keep a body alive. You may have had your little brushes with danger or perhaps a close call when you did something crazy or stupid. But for the most part, it’s a good chance you have all our fingers and limbs. You might have a scar or two, but you’re in good control of your faculties… So far.
With that in mind, Personal Protective Equipment (PPE), Safety Rules and Emergency Response Procedures take over when agility, reflex and muscular speed cannot. It’s important to remember that all injuries are preventable, but they are also more probable and even likely when you do not use PPE or adhere to safety rules and guidelines. Under those conditions, mishap and personal injury to yourself and someone else is almost a certainty.
In completing this exercise you learned how and when to use Personal Protective Equipment (PPE). You also learned how to use a portable fire extinguisher and how to respond to a spilled or leaking battery. It’s important to know that your instructor is the point of contact in emergency situations. If possible, all emergency response is to be coordinated through them. If you are not able to render assistance, it is your responsibility to find someone who can. You must find help.

Exercise 3 – Material Safety Data Sheets (MSDS)
Objective:
Upon the completion of this exercise, you will understand what Material Safety Data Sheets (MSDS) are, where they are located in your lab, and how to use them. You will research various chemicals and materials common to your lab and then use their MSDS information to determine the proper first aid, emergency response, and the proper disposal for objects you will use during your studies.
Information:
Although the types and amounts may vary from program to program, most labs require some use of chemicals to accommodate instruction. These materials may include batteries, lubricants, solvents, cleaners, paints or other types of chemicals. In fact, chemicals are prevalent in everyday life and knowing what they are as well as their safe use and disposal is very valuable information indeed. Manufactures are required to research the chemicals used to make their products and develop a standardized report that lists safety information regarding the product. These Material Safety Data Sheets (MSDS) allow consumers and secondary manufactures to prevent, prepare for and respond to safety incidents regarding the chemicals found in nearly all manufactured goods.
