What allows possible sources or methods of releases to be identified?

A facility survey is a systematic examination of a site to identify potential hazards and possible sources or methods of releases. This approach includes assessing the layout of the facility, the processes involved, and any materials present that could pose a risk of release into the environment.

During the survey, employees evaluate various areas of the facility, looking into storage practices, operational procedures, and any historical data on releases or spills. This comprehensive analysis helps in pinpointing vulnerabilities and aids in developing appropriate safety measures and response plans.

While a site map provides visual representation and context for facility layout, and critiques of response and follow-up focus on evaluating previous actions taken during incidents, they do not inherently identify potential release sources. Similarly, site control pertains to managing access and operations within hazardous areas but does not directly contribute to locating potential releases. Therefore, the facility survey stands out as the effective tool for identifying these risks.
