How does the 'Smell' step contribute to safety?

The 'Smell' step contributes to safety primarily by allowing individuals to detect harmful substances in their environment, such as smoke from a fire or chemical fumes that may indicate a hazardous situation. This sensory input can serve as an early warning system, alerting individuals to potential dangers before they are visible or felt. For example, noticing the smell of smoke can prompt actions like evacuating an area or investigating the source before a fire spreads, thus mitigating the risk of injury or worse.

In contexts where chemical exposure might be a concern, the ability to smell can also help identify toxic substances that may not have immediate physical effects but could lead to severe health issues if not addressed. The prompt recognition of these odors plays a critical role in situational awareness, helping ensure the safety of all individuals present.
