What approach to inherently safer design is used when adjusting the concentration of alcohol in a water solution?

Using a moderate concentration of alcohol in a water solution is a key element of inherently safer design because it balances efficiency with safety considerations. High concentrations of alcohol can increase flammability and toxicity, while very low concentrations may not achieve the desired effectiveness, whether it's for flavor or other applications.

By selecting a moderate concentration, you help mitigate risks associated with handling flammable materials. This approach aligns with the principles of inherently safer design, which prioritize minimizing hazards through design choices rather than relying solely on protective measures.

In many contexts, a moderate concentration can enhance safety by reducing the risk of ignition and subsequent fire hazards, making the overall process safer for both the operators and the environment. This approach is particularly crucial in industries where volatile substances are prevalent, as even small adjustments in concentration can significantly impact safety outcomes.
