For a residential gas leak with no hazard present, what type of response should be documented?

The correct choice is a documented response as a "Hazardous material release investigation with no hazardous condition found." This classification is appropriate in situations where a residential gas leak is reported but is determined to pose no immediate hazard to individuals or the environment.

Documenting the response in this manner emphasizes the investigative nature of the call, confirming that there was a potential hazardous situation (the gas leak), but following an assessment, it was determined that there were no dangerous conditions present. This provides a comprehensive record that both acknowledges the concern raised and the thorough response conducted, promoting accountability and awareness of similar future incidents.

Using this classification helps to maintain client safety and ensures that all necessary protocols are followed, even in the absence of an actual hazard. It also distinguishes this type of response from other potential classifications that would imply a more severe risk or hazard presence, which would not be suitable given the circumstances.
