What is the main aim of the 'Substitute' principle?

• A. Wrapping hazardous materials securely
• B. Using materials that are less hazardous than the originals
• C. Modifying existing processes to increase safety
• D. Hiring specialized personnel to manage hazards

Answer: (B)

The main aim of the 'Substitute' principle is to use materials that are less hazardous than the originals. This principle is a fundamental aspect of inherently safer design, which seeks to minimize risks by replacing dangerous substances with safer alternatives. By substituting hazardous materials with those that pose a lower risk to health and the environment, the potential for accidents, exposure, and other hazards is significantly reduced. This approach not only enhances safety but can also improve overall efficiency and sustainability in chemical processes. In contrast, wrapping hazardous materials securely focuses on containment and does not address the inherent dangers of the materials themselves. Modifying existing processes may improve safety characteristics but does not eliminate the hazards if the original materials remain unchanged. Hiring specialized personnel to manage hazards can help mitigate risks but does not fundamentally reduce the hazards associated with the materials or processes being used. Therefore, the objective of substitution is to eliminate hazards at the source, making it the most proactive and effective approach within the inherently safer design framework.
