Performance characteristics of materials including woods, metals, polymers, smart and modern materials, papers, boards, textiles, and composites, focusing on their properties to enable discrimination and appropriate selection.
Topic 7: Potential hazards and risk assessment in Design and Technology (Edexcel A-Level) focuses on identifying, evaluating, and controlling risks in design and manufacturing environments. This topic covers the legal framework (e.g., Health and Safety at Work Act 1974, COSHH, PUWER), hazard identification (e.g., mechanical, electrical, chemical, ergonomic), risk assessment methodologies (e.g., 5-step HSE approach), and control measures (e.g., hierarchy of control: elimination, substitution, engineering controls, administrative controls, PPE). Students learn to apply these principles to real-world design scenarios, such as workshop practices, material processing, and product testing.
Understanding risk assessment is critical for any designer or engineer, as it ensures the safety of users, manufacturers, and the environment. In the A-Level exam, this topic often appears in extended writing questions, where students must evaluate risks in a given context and propose justified control measures. It also links to broader topics like material properties, manufacturing processes, and product life cycle analysis, making it a key component of the 'Designing and Making Principles' paper.
Mastering this topic not only helps students achieve high marks but also instils a professional mindset essential for careers in design, engineering, and manufacturing. By the end of this topic, students should be able to conduct a thorough risk assessment, understand legal responsibilities, and communicate safety measures effectively.
