Question 1: Describe two common hazards that might occur during the manufacturing of a plastic product and explain how these hazards could be prevented.

Answer: Potential hazards include burns from hot equipment and cuts from sharp tools. Prevention methods include wearing protective gloves, using guards on machinery, and following safety procedures.

Question 2: Design a safe workspace layout for a small workshop where students will make a wooden box. Include at least three safety features in your plan.

Answer: A safe workspace plan should include designated areas for cutting, assembling, and finishing; clear walkways free of clutter; safety equipment like goggles and gloves readily available; proper ventilation; and emergency exits marked.

Question 3: Explain why it is important to wear safety goggles when working with power tools. Provide two scenarios where goggles are essential.

Answer: Safety goggles protect the eyes from flying debris, dust, or splinters. They are essential when drilling into wood or metal and when cutting materials that produce dust or small particles.

Question 4: Sketch a simple safety guard for a saw that could be used to prevent accidental contact with the blade. Label the key features of your design.

Answer: A correct sketch would show a protective cover that surrounds the saw blade, with an opening for the material to pass through. The guard should be securely attached, easy to remove for maintenance, and made of durable material. Labels should include 'protective cover,' 'adjustable opening,' and 'secure attachment.'

Question 5: List three personal safety precautions a student should follow when using a hot glue gun.

Answer: Wear protective gloves, avoid touching the hot nozzle or glue, and work on a heat-resistant surface. Also, unplug the glue gun when not in use.

Question 6: Plan and sketch a safety instruction poster for students working with electrical tools. Include at least three key safety messages and visual cues.

Answer: A clear poster might include messages such as 'Always unplug before adjusting,' 'Wear insulated gloves,' and 'Check for damaged cords.' Visual cues could be icons or symbols representing each message, with large, bold headings and easy-to-understand images or sketches.

Question 7: Identify two safety features that should be included in the design of a new electric hand drill to ensure user safety.

Answer: Features could include an automatic shut-off when overheating occurs and a safety lock switch to prevent accidental activation.

Question 8: Explain the importance of conducting a risk assessment before starting a manufacturing project. What are two questions you should ask during this assessment?

Answer: A risk assessment helps identify potential hazards to prevent accidents and injuries. Questions include 'What could cause injury during this task?' and 'What safety measures can be implemented to minimize risks?'

Question 9: Design a simple safety checklist for students to follow before operating machinery. List at least five safety steps.

Answer: The checklist should include steps such as checking that safety guards are in place, wearing appropriate protective gear, inspecting tools for damage, ensuring the workspace is clear, and confirming emergency stops are accessible.
