Practice Questions and Answers
1. Safety Practices
1. What is the primary purpose of a Job Safety Analysis (JSA)?
To identify potential hazards before starting a job and implement controls.
It ensures workers are aware of risks and preventive measures are in place.
2. Which type of fire extinguisher should be used on electrical fires?
Class C fire extinguisher.
Class C extinguishers are designed for energized electrical equipment.
3. What is the minimum distance to maintain from overhead power lines when using a
ladder?
At least 10 feet (3 meters).
Maintaining distance reduces the risk of electrocution.
4. What is the purpose of a safety data sheet (SDS)?
To provide information on handling, storage, and emergency procedures for
hazardous chemicals.
SDS contains crucial details for safe chemical use.
5. When should personal protective equipment (PPE) be worn?
Whenever a hazard cannot be eliminated or controlled by other means.
PPE is the last line of defense after engineering and administrative controls.
, 2. Hand Tools
6. What is the correct way to carry a sharp hand tool such as a chisel?
Point the sharp edge down and away from the body.
Prevents accidental cuts and injuries.
7. How often should hand tools be inspected?
Before each use.
Regular inspection ensures they are safe and functional.
8. What is the purpose of a torque wrench?
To apply a specific torque to a fastener.
Ensures bolts are neither too tight nor too loose.
9. Which hand tool is best for cutting metal pipe?
Hacksaw.
Hacksaws have fine-toothed blades designed for metal cutting.
10. What is the correct way to store hand tools?
In a designated tool box or rack, clean and dry.
Proper storage prevents damage and accidents.
3. Power Tools
11. What safety precaution is essential when using a circular saw?
Always use the blade guard and ensure the saw is unplugged when changing blades.
Prevents accidental contact with the blade.
12. Why should extension cords be rated for the tool’s amperage?
To prevent overheating and potential fire hazards.
Underrated cords can melt and cause electrical fires.
13. What is the purpose of a ground-fault circuit interrupter (GFCI)?
To protect against electric shock by shutting off power when a fault is detected.
GFCIs are critical in wet or conductive environments.
14. How should power tools be handled when working at heights?
Secure them with lanyards or tool belts to prevent drops.
Prevents injury to workers below.
15. What maintenance is required for pneumatic tools?
Regular lubrication and inspection for air leaks.
Ensures safe and efficient operation.
4. Construction Math
16. What is the volume of a concrete slab 10 ft long, 5 ft wide, and 0.5 ft thick?
25 cubic feet.
Volume = length × width × height → 10 × 5 × 0.5 = 25.
