Question 1Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

When handling a drum of corrosive parts cleaner, which personal protective equipment is the minimum requirement?

  1. Cotton gloves and a dust mask
  2. No PPE, provided the drum remains sealed
  3. Chemical gloves and splash goggles Correct answer.
  4. Leather work gloves and safety glasses

Explanation

Corrosive liquids can cause severe skin and eye damage, so chemical-resistant gloves and splash goggles or a face shield are required when handling them. Leather, cotton, and dust masks do not resist chemical splash.

Question 2Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

Under WHMIS, a supplier label showing a flame pictogram indicates which hazard?

  1. The product is corrosive
  2. The product is flammable Correct answer.
  3. The product is an oxidizer
  4. The product is acutely toxic

Explanation

The flame pictogram is used for flammable gases, liquids, and solids. Corrosive products use the corrosion pictogram, oxidizers use a flame over a circle, and acutely toxic products use a skull and crossbones.

Question 3Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

What is the correct technique for lifting a heavy box from the floor?

  1. Lift and twist at the same time to turn around
  2. Hold the box away from the body at arm's length
  3. Bend at the waist while keeping the legs straight
  4. Bend knees, keep back straight, hold load close Correct answer.

Explanation

Safe lifting keeps the load close to the body, uses the leg muscles, and maintains the natural curve of the back. Twisting while lifting increases the risk of back injury.

Question 4Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

Which class of fire extinguisher is intended for fires involving ordinary combustibles such as wood, paper, and cardboard?

  1. Class B
  2. Class D
  3. Class C
  4. Class A Correct answer.

Explanation

Class A extinguishers are for ordinary combustibles. Class B is for flammable liquids, Class C for energized electrical equipment, and Class D for combustible metals.

Question 5Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

What should be done with a socket that has a visible crack?

  1. Wrap the crack with electrical tape
  2. Grind the crack until it is smooth
  3. Use it only at low torque settings
  4. Discard it and replace it Correct answer.

Explanation

A cracked socket can shatter under load and send metal fragments toward the user. It must be removed from service and replaced, not repaired or used at reduced torque.

Question 6Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

When using a two-way radio in a noisy parts warehouse, what is the best practice?

  1. Turn the radio volume down to reduce feedback
  2. Speak rapidly to keep the channel clear
  3. Hold the mic close and speak clearly Correct answer.
  4. Use shop slang so messages are shorter

Explanation

Clear, slow speech with the microphone close to the mouth improves intelligibility in background noise. Standard terms rather than slang reduce miscommunication.

Question 7Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

What is the main purpose of a receiving report?

  1. To calculate employee payroll
  2. To order new stock from a supplier
  3. To list customers who bought parts
  4. To record goods received against the order Correct answer.

Explanation

A receiving report documents the quantity and condition of goods delivered and is matched against the purchase order and packing slip. This protects both inventory accuracy and payment accuracy.

Question 8Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

What is the function of a barcode scanner at a parts counter?

  1. It prints customer invoices
  2. It enters a part number into the system Correct answer.
  3. It measures the dimensions of a part
  4. It charges the customer's payment card

Explanation

A barcode scanner converts the barcode into a part number or identifier that the inventory system can look up. It speeds data entry and reduces keystroke errors.

Question 9Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

Which section of a Safety Data Sheet contains first-aid measures?

  1. Section 9
  2. Section 11
  3. Section 4 Correct answer.
  4. Section 7

Explanation

SDS Section 4 lists first-aid measures, while Section 7 covers handling and storage, Section 9 covers physical and chemical properties, and Section 11 covers toxicological information.

Question 10Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

A small solvent spill occurs in the parts room. What should be done first?

  1. Alert others, secure the area, and check the SDS Correct answer.
  2. Cover the spill with water and leave it
  3. Wash it into the floor drain with water
  4. Wipe it up with a dry paper towel and place the towel in regular trash

Explanation

The first priorities are to protect people and prevent the spill from spreading, then follow the SDS and spill kit instructions. Drains and regular trash are not appropriate for solvent waste.

Question 11Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

What does the acronym PASS describe in fire safety?

  1. The steps for using a fire extinguisher Correct answer.
  2. A storage method for compressed gas cylinders
  3. A forklift pre-use inspection checklist
  4. A type of personal protective equipment

Explanation

PASS stands for Pull the pin, Aim at the base of the fire, Squeeze the handle, and Sweep side to side. It is a memory aid for using a portable extinguisher.

Question 12Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

Before repairing a conveyor in the warehouse, which step is required?

  1. Isolate, lock and tag the energy source, then verify Correct answer.
  2. Ask a coworker to watch the control switch
  3. Reduce the conveyor speed to its lowest setting
  4. Place a warning sign on the control panel only

Explanation

Lockout/tagout requires isolating all energy sources, applying a personal lock and tag, and verifying that the equipment cannot start or move. A sign or a watcher does not provide the same protection.

Question 13Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

A shipment arrives with fewer items than the packing slip lists. Which document should be completed to record the shortage?

  1. A supplier backorder report
  2. A customer credit application
  3. A receiving discrepancy report Correct answer.
  4. A warehouse cycle count sheet

Explanation

A receiving discrepancy report records shortages, damage, or overages found at receiving and supports a claim or correction with the supplier. A cycle count checks inventory on hand, and a backorder records an out-of-stock item owed to a customer.

Question 14Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

What is the main function of a bill of lading?

  1. To authorize a price change on a customer account
  2. To record employee training records
  3. To list torque specifications for parts
  4. To act as a contract and receipt for goods Correct answer.

Explanation

A bill of lading is issued by the carrier and acts as a receipt for the goods, a contract of carriage, and often a document of title. It travels with the shipment and supports claims if goods are lost or damaged.

Question 15Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

What is the purpose of a cycle count in a parts warehouse?

  1. To verify selected inventory items on a schedule Correct answer.
  2. To calculate customer credit limits
  3. To automatically reorder stock from suppliers
  4. To count every item in the warehouse once a year

Explanation

Cycle counting checks a small number of items on a rotating schedule so errors are found and corrected without shutting down the warehouse. It is not the same as a full annual physical count.

Question 16Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

In a spreadsheet, which formula adds the values in cells B2 through B10?

  1. =ADD(B2+B10)
  2. =TOTAL(B2-B10)
  3. =SUM(B2:B10) Correct answer.
  4. =COUNT(B2;B10)

Explanation

The SUM function with a range such as B2:B10 adds every cell in that range. COUNT counts numeric entries rather than adding them.

Question 17Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

You receive an email asking you to click a link and enter your parts system password to verify your account. What should you do?

  1. Reply with your password to confirm it is you
  2. Forward the email to all coworkers
  3. Report it as phishing and don't click Correct answer.
  4. Click the link but enter a fake password

Explanation

Unexpected requests for credentials are a common phishing tactic; the safe response is to report the message through the organization's process and avoid the link. Legitimate IT staff do not ask for passwords by email.

Question 18Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

What is the best way to reduce strain at a computer workstation?

  1. Lean forward toward the monitor
  2. Work without breaks to finish faster
  3. Place the keyboard on your lap
  4. Adjust chair and monitor for eye-level screen Correct answer.

Explanation

A neutral seated posture with the screen near eye level, feet supported, and elbows near 90 degrees reduces musculoskeletal strain. Regular breaks and stretching also help.

Question 19Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

Which pair of products should be stored separately from each other?

  1. Oxidizers and flammable solvents Correct answer.
  2. Two brands of the same motor oil
  3. Two containers of identical coolant
  4. Empty sealed paint cans

Explanation

Oxidizers can intensify a fire and react violently with flammable materials, so they must be segregated. Similar products can usually be stored together under the site's rules.

Question 20Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

What does a backorder indicate?

  1. The item is out of stock but due later Correct answer.
  2. The item was damaged in shipping
  3. The item is discontinued and no longer available
  4. The item was returned by a customer

Explanation

A backorder records an item that a customer ordered but that is not currently in stock, with the expectation that it will be supplied when available. Discontinued items cannot be backordered in the same way.

Question 21Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

A parts technician is shipping a container of used oil to a recycler. Which document is required under transportation of dangerous goods regulations?

  1. A dangerous goods shipping document Correct answer.
  2. A material return authorization
  3. A purchase order
  4. A packing slip only

Explanation

Dangerous goods shipments require a shipping document with the proper shipping name, class, UN number, quantity, and emergency contact information. A packing slip alone does not meet the requirement.

Question 22Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

A metric micrometer shows 5.0 mm on the sleeve and 28 divisions on the thimble. What is the reading?

  1. 5.53 mm
  2. 5.78 mm
  3. 5.28 mm Correct answer.
  4. 5.028 mm

Explanation

The thimble has 50 divisions, each representing 0.01 mm, so 28 divisions equals 0.28 mm. Adding the sleeve reading gives 5.0 + 0.28 = 5.28 mm.

Question 23Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

After a machine has been locked out, which action verifies that the lockout is effective?

  1. Checking that the lock is the correct colour
  2. Placing the key in a locked cabinet
  3. Try to start it and test for zero energy Correct answer.
  4. Asking a supervisor to sign the tag

Explanation

Verification means trying the start control and testing the circuit or moving parts to confirm no energy is present. If the machine starts or energy is detected, the lockout is not complete.

Question 24Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

In crane hand signals, what does a raised clenched fist mean?

  1. Move the load forward
  2. Hoist the load
  3. Stop Correct answer.
  4. Lower the load

Explanation

A clenched fist held up is the standard stop signal. Hoist and lower use different arm and hand motions, so the signal person must use the agreed code.

Question 25Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

When a hazardous product is transferred from a supplier container into a secondary container in the shop, what must the secondary container have?

  1. A workplace label showing product and hazards Correct answer.
  2. No label if used during the same shift
  3. Only the supplier's original label
  4. A label showing only the expiry date

Explanation

Workplace labels are required for secondary containers and must identify the product and provide safe handling information, often through a symbol or reference to the SDS. The supplier label stays on the original container.

Question 26Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

A parts technician must lift a heavy boxed alternator from the warehouse floor onto a bench. Which lifting method best reduces the risk of back injury?

  1. Twist at the waist while lifting to swing the load onto the bench
  2. Bend the knees and lift with the legs Correct answer.
  3. Keep the legs straight and bend forward at the waist to reach under the load
  4. Hold the load away from the body to keep it clear of the toes

Explanation

Safe manual lifting relies on the leg muscles and keeps the load close to the body's centre of gravity, which shortens the lever arm on the lower back. Bending the knees allows the strong thigh muscles to do the work while the spine stays in a neutral position.

Question 27Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

A parts technician needs to loosen a rusted flare nut on a steel brake line without damaging the fitting. Which tool is best suited to this job?

  1. A pipe wrench with serrated jaws
  2. An adjustable wrench
  3. A 12-point box-end wrench
  4. A flare nut (line) wrench Correct answer.

Explanation

A flare nut wrench grips several flats of the fitting and has a slot that lets it slip over the tube, so torque is spread over the nut instead of a few points. This prevents rounding of the relatively soft hex on brake line fittings.

Question 28Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

A customer returns a defective starter that is still under the supplier's warranty. Which document must normally be obtained from the supplier before the part is sent back?

  1. A cycle count sheet from the warehouse
  2. A bill of lading signed by the receiving clerk
  3. A receiving report with the original packing slip attached
  4. A return goods authorization (RGA) Correct answer.

Explanation

Suppliers issue a return goods authorization before accepting returned stock, and the number ties the shipment to a credit, repair, or replacement. Returns shipped without prior authorization are often refused at the dock or credited incorrectly.

Question 29Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

A parts technician has a spreadsheet of 4,000 part numbers and wants to see only the items whose on-hand quantity is below the reorder point. Which spreadsheet feature should be used?

  1. Merge the on-hand quantity cells into one cell
  2. Apply a filter to the on-hand quantity column Correct answer.
  3. Freeze the header row so the column titles stay visible
  4. Sort the on-hand quantity column from smallest to largest

Explanation

Filtering hides rows that do not meet a criterion while leaving the underlying data intact, so only the parts below the reorder point remain visible. It is the standard way to isolate a subset of records without deleting or moving anything.

Question 30Common Occupational Skills (safety, tools and equipment, communication, documentation, computer applications)

A forklift strikes an upright on a pallet rack in the parts warehouse, leaving it visibly bent. What is the correct response?

  1. Reload the bay with heavier parts to stabilize the bent upright
  2. Take the bay out of service, unload it, and report the damage to a supervisor Correct answer.
  3. Record the damage on the next scheduled rack inspection sheet and keep light loads in that bay
  4. Straighten the upright with a pry bar and put the bay back into service

Explanation

A bent upright has lost structural capacity and can collapse without warning, so the load must be removed and the bay blocked off or tagged until a competent person inspects and repairs it. Prompt reporting ensures the repair follows the rack manufacturer's instructions.

Question 31Parts Identification and Cataloguing (catalogue/interchange lookup, numbering systems, terminology)

A part number that is assigned by the vehicle manufacturer and sold through its dealer network is best described as a(n):

  1. OEM part number Correct answer.
  2. Interchange number
  3. Casting number
  4. Aftermarket number

Explanation

An OEM part number is created and controlled by the vehicle manufacturer for parts sold through its own distribution channel. Other numbering types serve different purposes: cross-referencing, identifying raw castings, or identifying independently produced replacement parts.

Question 32Parts Identification and Cataloguing (catalogue/interchange lookup, numbering systems, terminology)

In a parts catalogue, what is the purpose of an interchange listing?

  1. Records vehicle build dates
  2. Lists fastener torque values
  3. Shows equivalent parts sold by other suppliers Correct answer.
  4. Gives installation labour times

Explanation

An interchange, or cross-reference, section maps a given part to equivalents offered by other manufacturers or to other numbering systems. It is used to find an alternative source for the same application, not to supply service data.

Question 33Parts Identification and Cataloguing (catalogue/interchange lookup, numbering systems, terminology)

How many characters are in a VIN built to the current North American standard?

  1. 15
  2. 21
  3. 17 Correct answer.
  4. 10

Explanation

Since the 1981 model year, the standardized VIN has contained 17 characters. Each position has a defined meaning, which is why the VIN can be used to narrow a parts lookup.

Question 34Parts Identification and Cataloguing (catalogue/interchange lookup, numbering systems, terminology)

When a component is catalogued as LH, which side of the vehicle does it fit?

  1. Left as determined from the driver's seat facing forward Correct answer.
  2. The side nearest the driver on every vehicle
  3. The side on the left when viewing the vehicle from the front
  4. The side opposite the fuel filler neck

Explanation

Left and right are always determined from the driver's seat facing forward, the same orientation used for the vehicle's own reference. This convention holds regardless of the market's steering side.

Question 35Parts Identification and Cataloguing (catalogue/interchange lookup, numbering systems, terminology)

A hose catalogued with a dash size of -06 has an inside diameter of:

  1. 3/16 in
  2. 1/4 in
  3. 3/8 in Correct answer.
  4. 1/2 in

Explanation

Dash numbers express the nominal inside diameter in sixteenths of an inch, so -06 equals 6/16, or 3/8 in. The same scale makes -04 equal 1/4 in and -08 equal 1/2 in.

Question 36Parts Identification and Cataloguing (catalogue/interchange lookup, numbering systems, terminology)

How many radial lines mark the head of an SAE grade 5 bolt?

  1. Three Correct answer.
  2. Five
  3. Two
  4. Six

Explanation

SAE bolt grades are identified by radial lines on the head: grade 2 has none, grade 5 has three, and grade 8 has six. The markings let a technician confirm strength without measuring the fastener.

Question 37Parts Identification and Cataloguing (catalogue/interchange lookup, numbering systems, terminology)

In an illustrated parts catalogue, what does the number shown next to a component in the exploded view represent?

  1. The quantity used per vehicle
  2. The item reference that matches the parts list Correct answer.
  3. The casting number of the component
  4. The OEM part number to order

Explanation

Illustration callouts are reference numbers only; they link each pictured component to its line in the accompanying parts list. The actual part number and quantity are read from that list.

Question 38Parts Identification and Cataloguing (catalogue/interchange lookup, numbering systems, terminology)

A catalogue note states that part 12345 supersedes part 12300. What should the counterperson do?

  1. Treat 12300 as the improved version
  2. Order both numbers and install them together
  3. Order 12345, which replaces 12300 Correct answer.
  4. Advise that the part is no longer available

Explanation

Supersession means the newer number replaces the older one, usually because of an engineering change; the older number is no longer supplied. The current number is the one ordered and stocked.

Question 39Parts Identification and Cataloguing (catalogue/interchange lookup, numbering systems, terminology)

A parts list shows two versions of a component split by a serial number break. What must the counterperson determine before selecting the part?

  1. The supplier that built the component
  2. The price difference between the two versions
  3. The vehicle's serial number or break point Correct answer.
  4. The colour code of the component

Explanation

A serial number break means the design changed partway through production, so the vehicle's own number decides which version applies. Identifying the vehicle correctly avoids ordering the version that will not fit.

Question 40Parts Identification and Cataloguing (catalogue/interchange lookup, numbering systems, terminology)

Why can a casting number found on a component usually not be used as the order number?

  1. It is the dealer's internal order code
  2. It is always identical to the finished service part number
  3. It is the aftermarket interchange number
  4. It identifies the cast part, not the service part Correct answer.

Explanation

A casting number identifies the raw casting and the tooling that produced it; the finished service part may be machined, assembled, or updated, which changes its service number. Catalogue lookup should always be by the service part number for the application.

Question 41Parts Identification and Cataloguing (catalogue/interchange lookup, numbering systems, terminology)

A metric fastener is marked M10 x 1.5. What does the 1.5 indicate?

  1. The shank diameter is 1.5 mm
  2. The head takes a 1.5 mm wrench
  3. The thread pitch is 1.5 mm Correct answer.
  4. The bolt is 1.5 in long

Explanation

In metric fastener callouts the first number is the nominal diameter in millimetres and the second is the thread pitch, the distance between adjacent threads. A 1.5 pitch on an M10 is the common coarse thread for that size.

Question 42Parts Identification and Cataloguing (catalogue/interchange lookup, numbering systems, terminology)

A serpentine belt is listed as 6PK1200. What does this code tell the technician?

  1. Six ribs with a 1200 mm effective length Correct answer.
  2. Six teeth driving a 1200-tooth sprocket
  3. Six millimetres wide and 1200 mm long
  4. Six plies rated for 1200 N of tension

Explanation

In this common belt code the first figure is the number of ribs, PK identifies the rib profile, and the final figure is the effective length in millimetres. Matching both rib count and length is required for correct fitment.

Question 43Parts Identification and Cataloguing (catalogue/interchange lookup, numbering systems, terminology)

A bearing is designated 6205-2RS. What does the 2RS suffix mean?

  1. Two rubber seals Correct answer.
  2. Two snap rings
  3. A tapered bore
  4. A roller cage with two rows

Explanation

The suffix describes the sealing arrangement: 2RS indicates a seal on both sides, while ZZ would indicate two metal shields. Suffix codes are read after the basic bore and series numbers.

Question 44Parts Identification and Cataloguing (catalogue/interchange lookup, numbering systems, terminology)

A customer requests an 1157 bulb. What characteristic defines this bulb type?

  1. It has two filaments and offset pins Correct answer.
  2. It has a single filament and a bayonet base
  3. It fits only wedge-type sockets
  4. It is a sealed-beam halogen unit

Explanation

The 1157 is a dual-filament bulb used for combined stop and tail functions, with offset locating pins so it seats only one way in the socket. That dual circuit is what separates it from its single-filament counterpart, the 1156.

Question 45Parts Identification and Cataloguing (catalogue/interchange lookup, numbering systems, terminology)

A customer asks for a harmonic balancer, but the catalogue lists the item under a different name. What is the best approach?

  1. Refuse the order until an OEM number is supplied
  2. Order the part by the customer's description alone
  3. Order the most expensive version to be safe
  4. Search under the standard name and cross-reference the trade term Correct answer.

Explanation

Catalogues use standard nomenclature, while customers often use trade or regional terms for the same item. Recognising the trade term and confirming it against the catalogue description gives the right part without delaying the customer.

Question 46Parts Identification and Cataloguing (catalogue/interchange lookup, numbering systems, terminology)

A universal part is catalogued by dimensions rather than by vehicle application. How should it be selected?

  1. Choose by the vehicle's model year only
  2. Choose the largest size listed to allow adjustment
  3. Choose by the price of the item
  4. Measure the original against the listed dimensions Correct answer.

Explanation

Universal items are not tied to a specific application, so the only reliable selection method is comparing the original component's measurements with those published for the item. Year, price, and guesswork cannot confirm fit.

Question 47Parts Identification and Cataloguing (catalogue/interchange lookup, numbering systems, terminology)

Which vehicle information does the eighth character of a VIN provide?

  1. The engine code Correct answer.
  2. The check digit
  3. The model year
  4. The assembly plant

Explanation

Positions four through eight carry vehicle attributes, and the eighth character specifically identifies the engine installed. This is why engine parts lookups rely on the VIN rather than on the year and model alone.

Question 48Parts Identification and Cataloguing (catalogue/interchange lookup, numbering systems, terminology)

A part number carries a trailing letter suffix after the base number. What does the suffix normally indicate?

  1. The supersession history of the part
  2. A colour or side variation of the base part Correct answer.
  3. An alternate manufacturer who builds the same part
  4. The quantity contained in the package

Explanation

Suffix letters distinguish variations built on a common base number, such as colour, left or right, or a minor design level. Because the meaning differs between manufacturers, the catalogue legend should always be checked.

Question 49Parts Identification and Cataloguing (catalogue/interchange lookup, numbering systems, terminology)

An engine catalogue lists a piston as .020 OS. What does this mean?

  1. It weighs 0.020 kg more than standard
  2. It is 0.020 in oversize for a rebored cylinder Correct answer.
  3. It is 0.020 in undersize and needs a sleeved bore
  4. It is the twentieth piston in a matched set

Explanation

Oversize markings tell the machinist and parts person what bore size the component is made for; .020 OS fits a cylinder bored 0.020 in larger than standard. The matching piston-to-bore clearance must be maintained during machining.

Question 50Parts Identification and Cataloguing (catalogue/interchange lookup, numbering systems, terminology)

Which VIN position contains the check digit?

  1. Tenth
  2. Eighth
  3. Fourth
  4. Ninth Correct answer.

Explanation

The ninth character is a calculated check digit used to validate that the VIN has been transcribed correctly. It carries no vehicle attribute, which is why it is never used for parts lookup.
