Which approach is considered inherently safer when developing processes?

The choice of wider safer operating limits is considered inherently safer when developing processes because it provides a larger margin of safety in operational conditions. This approach allows processes to operate effectively without being pushed to their limits, which can minimize the likelihood of accidents and unintentional releases. By ensuring that the operating conditions remain well within safe ranges, the risks associated with process variability and unforeseen events are reduced.

Wider operating limits enhance the ability of a facility to absorb disturbances without leading to a failure or hazardous situation. This is essential in inherently safer design, which aims to eliminate, reduce, or control hazards at the source rather than relying solely on protective measures or equipment.

In contrast, narrower operating limits could increase risk by operating closer to the threshold of safety. Unpredictable processes introduce variability and uncertainty, likely leading to higher hazards, while the use of hazardous materials inherently increases the risks associated with potential releases and accidents. Therefore, wider safer operating limits facilitate a design that inherently reduces risks and enhances overall safety in process operations.
