35.4. Safety Engineering and Design Principles

Try these first

1. 1.

   What is inherently safe design?

   Hint

   Think of examples where safety is prioritized before a failure.

2. 2.

   Name one benefit of safety-related control systems.

   Hint

   Consider emergency measures or alerts.

3. 3.

   What does inherently safe design aim to do?

   • Control hazards
   • Avoid hazards
   • Ignore hazards

   Hint

   Think about the difference between avoiding and controlling.

4. 4.

   True or False: Redundant actuators ensure safety by providing backup mechanisms.

   • True
   • False

   Hint

   Consider what happens when a primary system fails.

5. 5.

   Design a simple robotic system using the concepts from inherently safe design principles. What features would you include to ensure safety?

   Hint

   Think of everyday devices that prioritize user safety.

6. 6.

   Evaluate a given machine's control system for safety-related aspects. Identify potential failure points and propose safety enhancements.

   Hint

   Look for the areas where human errors could lead to safety issues.
