Question 1: Identify three common hazards that might occur during the manufacturing of a plastic container. Explain how these hazards could be prevented.

Answer: Potential hazards include sharp tools causing cuts, fumes from heating plastic, and burns from hot equipment. Prevention methods include wearing protective gloves and goggles, working in a well-ventilated area, and using heat-resistant gloves or tools.

Question 2: Describe three safety features that should be incorporated into a hand saw used for woodworking.

Answer: Safety features include a blade guard to cover the cutting edge, a non-slip handle for a secure grip, and a blade lock mechanism to prevent accidental movement.

Question 3: Sketch a simple layout of a safe workstation for making a small wooden box. Include two safety features you would add to the workspace.

Answer: A correct sketch would show a work surface with adequate space, tools stored properly, a fire extinguisher nearby, and safety goggles or gloves placed within reach. The safety features could include a dust extraction system and clearly marked emergency exits.

Question 4: Explain why it is important to wear protective equipment, such as goggles and masks, when working with certain materials.

Answer: Protective equipment helps prevent injuries from flying debris, dust, fumes, or chemicals. It reduces the risk of eye injuries, respiratory problems, and skin irritation.

Question 5: Design a safety label for a power drill that highlights two safety precautions. Include a brief explanation of each precaution.

Answer: A safety label should include warnings like 'Wear safety goggles' and 'Ensure the drill is unplugged when changing bits.' These precautions help prevent eye injuries and accidental activation.

Question 6: Describe the process of safely testing a newly assembled electrical circuit that includes a battery, switch, and light bulb. What precautions should be taken?

Answer: First, check all connections are correct and insulated. Then, wear protective gear and test the circuit with the power off. When testing, turn on the switch carefully, and avoid touching exposed wires to prevent electric shock or short circuits.

Question 7: Sketch a plan for a protective cover for a hot glue gun. Label two safety features that would make it safer to use.

Answer: A correct sketch would show a cover that encloses the heating element, with a non-slip base. Safety labels or indicators for heat status, and a handle designed to stay cool, are two safety features.

Question 8: List and explain two safety rules that should be followed when using sharp cutting tools in a workshop.

Answer: Rules include: always cutting away from your body to avoid injury, and using a clamp or vice to secure materials so they do not move unexpectedly.

Question 9: Identify two ways to prevent fire hazards when working with electrical tools or equipment in a workshop.

Answer: Ways include: ensuring electrical cords are in good condition without frays or damage and keeping flammable materials away from electrical sparks or heat sources.

Question 10: Describe how you would plan to keep your workspace safe while making a product involving hot materials and sharp tools.

Answer: The plan should include organizing tools and materials to prevent clutter, wearing protective gear, keeping a fire extinguisher nearby, and ensuring good lighting and ventilation. Also, having a clear procedure for handling hot and sharp items safely.
