UNIQUE NO.
DUE DATE: 23 SEPTEMBER 2025
, Safety Management IIA
Question 1 (6 Marks)
1.1 Define engineering for safety and safety engineering (4)
Engineering for safety refers to the proactive integration of safety principles into the
design of equipment, processes, and systems. It focuses on eliminating or minimising
hazards at the source during the design phase rather than relying solely on
administrative measures or personal protective equipment (Nkuna, 2024).
Safety engineering involves the systematic application of engineering principles and
tools—such as risk assessments, Failure Mode and Effects Analysis (FMEA), and fault
tree analysis—to identify, evaluate, and control hazards throughout the life cycle of a
system (Manuele, 2020). It is often more reactive, ensuring existing systems remain
safe through continuous improvement and monitoring.
1.2 How they complement each other (2)
Engineering for safety and safety engineering complement each other by addressing
hazards across the system’s lifecycle. Engineering for safety ensures that hazards are
designed out at the source, while safety engineering provides methods and tools to
continuously monitor and control risks that may emerge in operation. Together, they
create a holistic, preventive approach to workplace safety.
Question 2 (6 Marks)
2.1 Five-step design process applied to the grinder incident (5)
1. Define the problem: The angle grinder caused a hand injury due to poor
guarding.
