Question 2: In Ontario industrial trades, what is the primary purpose of a torque wrench?
- To apply a specific amount of rotational force to a fastener (Correct answer)
- To remove rusted bolts
- To measure thread pitch
- To cut threaded rods
Correct answer: To apply a specific amount of rotational force to a fastener
A torque wrench is used to apply a precise, specified amount of rotational force (torque) to fasteners to ensure proper tightening.
Question 3: Which PPE is required when operating a bench grinder in a trade shop?
- Safety glasses or face shield (Correct answer)
- Steel-toed boots only
- Hard hat only
- Hearing protection only
Correct answer: Safety glasses or face shield
Safety glasses or a face shield must be worn when operating a bench grinder to protect against flying sparks and debris.
Question 4: What does the term 'calibration' mean in the context of industrial trade tools?
- Adjusting a tool to ensure its measurements are accurate against a known standard (Correct answer)
- Cleaning tools after use
- Sharpening cutting edges
- Lubricating moving parts
Correct answer: Adjusting a tool to ensure its measurements are accurate against a known standard
Calibration is the process of adjusting or verifying a tool's accuracy by comparing it to a known reference standard.
Question 5: When using an angle grinder, which action is considered a safety best practice under Ontario trade standards?
- Inspecting the wheel for cracks before use (Correct answer)
- Running the grinder at half speed always
- Removing the guard to improve visibility
- Using the grinder only for cutting metal
Correct answer: Inspecting the wheel for cracks before use
Inspecting the grinding wheel for cracks or defects before use is a mandatory safety step to prevent wheel failure and injury.
Question 6: What type of drill bit is best suited for drilling into hardened steel in industrial applications?
- Cobalt or carbide-tipped bit (Correct answer)
- Standard high-speed steel (HSS) bit
- Wood spade bit
- Masonry bit
Correct answer: Cobalt or carbide-tipped bit
Cobalt or carbide-tipped drill bits are designed to withstand the heat and hardness of drilling into hardened steel.
